Custom Mining & Metallurgical Equipment Parts
1. Excavator, Drilling & Mobile Mining Equipment Parts
Mining excavators, drilling machines and mobile equipment use load-bearing pins, links, track components, equipment mounts and wear-contact parts. SIMIS offers drawing-based metal parts such as hydraulic breaker rod pins, lift arms, link arms and track shoe and pad plates. The production route depends on each component: selected pins and shafts may be forged and machined, while suitable complex seats, brackets and other shapes may be cast.
For replacement or OEM parts, confirm the equipment model and approved drawing rather than relying on a nominal part name. Important details include pivot-pin diameter, mating-bore fit, hole spacing, surface hardness, wear allowance, mounting geometry and the specified steel grade. Impact and cyclic loading should be reviewed alongside any required hardening, NDT or dimensional acceptance criteria.
2. Conveyor Chains, Sprockets & Drive Components
Ore conveyors and bulk-handling systems use chains, sprockets, rollers, shafts, flights and power-transmission parts. Relevant SIMIS products include scraper conveyor chain components, screw conveyor shafts, pulleys and sheaves and ring gears. Forged steel may suit selected shafts and connectors; cast steel or ductile iron can be evaluated for suitable sprockets, housings and transmission parts. Fabricated conveyor structures are a separate process choice.
The manufacturing review should cover chain pitch, engagement geometry, roller or sprocket diameter, shaft runout, keyways, heat treatment and abrasive dust exposure. Where the OEM provides wear-life or hardness targets, material and acceptance tests are agreed against those requirements rather than assuming every conveying component uses the same wear-resistant alloy.
3. Crusher, Grinding Mill & Wear-Resistant Parts
Crushing and grinding equipment places different demands on structural castings and replaceable wear parts. SIMIS product examples include crusher hammer heads, ball mill liners and chocky wear bars. Selected crusher bodies and bearing supports can be evaluated as castings, while shafts and other heavily loaded components may require forged blanks and finish machining.
Material choice must match the dominant wear mechanism. High-manganese steel can be evaluated for applications with suitable repeated impact; high-chromium wear-resistant iron may be relevant where abrasion dominates and impact conditions permit. Neither alloy is universally superior. For liners and hammer heads, confirm working profile, fixing holes, section thickness, hardness or microstructure requirements, mating dimensions and the agreed inspection plan.
4. Metallurgical Furnace & Rolling Equipment Parts
Metallurgical plants require metallic parts for material handling, rolling equipment, furnace auxiliaries and mechanical drives. SIMIS examples include rolling mill roller shafts, bearing seats, valve parts and equipment brackets and connectors. Steel casting, forging and machining may be appropriate for specified shafts, supports and mechanical interfaces; sheet fabrication should be considered separately for suitable ducts, covers and panels.
Define actual exposure before selecting an alloy: ambient-temperature rolling equipment, hot-area supports and components contacting furnace gases are not interchangeable. Drawings should specify operating temperature, thermal cycling, loads, material/heat-treatment condition and corrosion or scaling requirements. Furnace vessels, pressure-containing equipment and safety-rated assemblies require their own engineering qualification and cannot be assumed from a general metal-parts quotation.
5. Equipment Bases, Bearing Housings & Structural Supports
Crusher stations, screens, ore-handling machinery and processing lines depend on accurately located bearing supports, machine feet, mounting blocks and heavy-duty connectors. SIMIS offers custom bearing seats and housings, metal brackets, shock-mount brackets and counterweight blocks. Cast iron or cast steel may be suitable for particular stiff, complex bases, while forged steel suits selected pins, shafts and other highly loaded connectors.
Review the full assembly interface: base flatness, bearing-bore alignment, bolt-hole pattern, welding or mounting provisions, vibration exposure, lifting points and machining datum strategy. Large welded frames should not be described as single-piece castings; casting, fabrication and machining are chosen according to the customer design, transport limits and required acceptance criteria.
6. Mine Hoist, Winch & Lifting Hardware
Mine hoists, winches and maintenance-lifting systems use drum-related parts, rope-handling fittings, pulley shafts, hooks, pins and structural mounting hardware. Relevant examples from SIMIS include pulleys and sheaves, tow hooks, cylinder trunnions and shaft flange yokes. Forged steel can be assessed for selected load-bearing pins and connectors; cast steel or iron may suit certain housings, sheaves and supporting components when the design permits.
Hoisting parts can be safety-critical. Define the applicable duty classification, loading direction, fatigue requirements, material certificates, proof or functional tests and purchaser-required approvals before quotation. Manufacturing a component to a drawing is not the same as certifying a complete hoist or lifting assembly; no particular load rating or compliance approval is implied without project-specific evidence.
7. Slurry Handling, Dust Control & Recovery Equipment Parts
Green practices in mining and metal work need good environmental and energy recovery systems. Castings and forgings make parts like desulfurization tower shells, heat exchangers, fan blades, and energy recovery rotors.
Their resistance to rust, high heat, and high strength improves the equipment's stability and efficiency. This lowers energy use and environmental harm.
-
Castings: Flue gas desulfurization tower shell, Exhaust pipe, Waste heat boiler shell, Heat exchanger shell
-
Forgings: High-pressure fan blade shaft, Energy-saving valve body, Energy recovery rotor
Materials for Mining Equipment & Wear Parts
Gray, Ductile & Wear-Resistant Cast Iron
Gray iron may suit selected rigid bearing supports, housings and equipment bases where damping and machinability matter. Ductile iron can be evaluated for specific transmission and support castings that call for additional ductility. Alloyed or wear-resistant cast irons are relevant to particular abrasive applications, including some mill liners and slurry-handling parts. SIMIS provides drawing-based iron casting and finish-machining options.
Specify the grade, as-cast section, working temperature, hardness or microstructure where relevant, and the required machining surfaces. High-chromium white iron offers a different hardness–toughness balance from gray or ductile iron; it is not a direct substitute for a shock-loaded structural component.
Cast, Forged & Wear-Resistant Steels
Cast carbon and alloy steels can be considered for suitable crusher components, housings and heavy equipment parts. Forged carbon or alloy steel is relevant to shafts, pins, couplings and other components needing a specified wrought condition. High-manganese or other wear-resistant cast steels may suit defined impact-and-abrasion conditions, while stainless grades serve selected corrosion-exposed equipment. See SIMIS steel casting applications for related material families.
Selection depends on actual impact energy, abrasive media, required toughness, heat treatment, weldability and the customer material specification. Hardness alone does not determine field wear life; chemistry, heat-treatment condition, microstructure, casting section and attachment design must also be evaluated.
Aluminum Alloys for Auxiliary Mining Equipment
Aluminum castings or machined aluminum components can suit selected auxiliary housings, motor covers, control enclosures, lightweight brackets and heat-dissipation parts. For example, motor housings may use aluminum where the specified geometry, loads and environmental conditions permit. Such components are generally different from primary crusher wear surfaces, high-impact liners and heavily loaded steel pins.
Confirm the alloy and temper or casting condition, wall thickness, machinability, surface finish, sealing interfaces and any required protective coating. Do not assume an aluminum part meets explosion-protection, electrical or mine-site equipment certification requirements solely from its material or casting process.
Bronze, Copper Alloys & Other Specified Metals
Bronze and other copper alloys can be relevant for customer-defined plain bearings, bushings, wear sleeves, valve parts and electrical or mechanical interfaces. Selection depends on contact pressure, sliding speed, lubrication, corrosion exposure and compatibility with the mating shaft. A bronze bearing and an abrasion-resistant crusher liner perform different functions and should not be specified interchangeably.
SIMIS can review other customer-specified alloys for appropriate cast or machined parts, subject to actual production feasibility. Provide the exact alloy designation, acceptable manufacturing condition and testing requirements. The intended application of valve components or bushings should guide the material choice, not a generic claim that all special metals withstand high heat or chemical exposure.
Engineering Review, Manufacturing & Quality Control
3D Drawings
Processing Drawing
Sample
1. Review Drawings, Wear Conditions & Service Loads
Provide the 2D manufacturing drawing and, where available, 3D model, target quantity, current part photos and assembly information. The engineering review identifies the component function, maximum dimensions, material specification, machining interfaces and required surface condition. For mining equipment, it is particularly helpful to distinguish fixed structural parts from replaceable wear parts and safety-critical load-bearing components.
Confirm whether wear is mainly sliding abrasion, particle erosion, crushing impact or a combination, together with expected loads, operating temperature, moisture, slurry chemistry and maintenance constraints. These inputs help determine whether casting, forging, machining or a fabricated construction is technically appropriate. Incomplete field data is discussed as a design assumption, not presented as a verified performance requirement.
2. Define Material Grades, Hardness & Acceptance Criteria
Review the required material standard and grade, mechanical-property condition, heat-treatment state and any specified hardness range. A crusher liner, a mill liner and a hydraulic breaker pin may require very different combinations of impact toughness, abrasion performance and dimensional stability. If a material substitution is proposed, it should be reviewed and accepted by the customer before production.
Agree on the inspections that the project actually needs, such as material chemistry, mechanical testing, hardness, dimensional examination, visual surface checks and any required nondestructive examination. Special requirements including microstructure checks, ultrasonic or magnetic particle testing, pressure or leak checks and wear trials depend on drawing, standard and purchase agreement. They are not assumed to be performed on every order.
3. Plan Casting, Forging, Tooling & Machining
Select the manufacturing route based on geometry, metal grade, section thickness, part quantity and acceptance requirements. Cast mining parts may need specific pattern allowances, feeding arrangements, cores and controlled cooling; steel forgings require an appropriate blank size, deformation plan and machining stock. For welded or sheet-metal parts, joint design and dimensional control are reviewed separately.
Define important machining datums before tooling release. Examples include liner mounting-hole patterns, crusher housing bearing bores, conveyor shaft keyways, gear interfaces and pump sealing faces. Confirm which surfaces remain as-cast or as-forged and which will be finished by CNC machining. Tooling scope, production lead time and initial sample quantity are established for the specific RFQ rather than promised as universal figures.
4. Produce Samples & Verify Critical Features
Manufacture first articles or samples according to the agreed process plan and approved drawing. Check major dimensions and relevant functional features: liner bolt holes, wear profiles, shaft diameters, bearing-seat locations, impeller mounting features or hydraulic passage geometry. Confirm surface condition and the intended fit with mating equipment wherever reference dimensions are available.
Sample acceptance may also require chemistry, hardness, heat-treatment evidence, mechanical-property results or nondestructive examination when specified. Identify deviations clearly and agree on any corrections before continuing. A first-article review helps establish manufacturability; it does not by itself certify the complete mining machine or guarantee a stated service-life improvement.
5. Control Batches, Heat Treatment & Traceability
After drawing and sample approval, organize repeat production using the agreed manufacturing route, control plan and acceptance criteria. Monitor relevant process factors such as casting composition and pouring conditions, forging stock and temperature, heat-treatment cycle, machining setup, tool condition and dimensional checks. Apply suitable controls to the wear profile or mechanical interfaces that determine how the part installs and works.
Where the customer requires traceability, maintain links among purchase order, drawing revision, material or melt/heat identification, processing batches and inspection results. Revisions, deviations and subcontracted treatment or finishing operations should be controlled within the agreed supply scope. Production consistency is managed through defined checkpoints rather than a blanket claim that every component is identical or individually tested.
6. Final Inspection, Records & Protective Delivery
Perform final acceptance against the released drawing and order requirements, checking dimensions, visible defects, marking, coating, hole positions and relevant machined surfaces. For wear components, verify the specified hardness or other acceptance results when those tests form part of the inspection plan. For machined shafts and housings, confirm critical fits, thread requirements and assembly surfaces.
Prepare the agreed certificates, dimensional records and test reports as applicable. Protect finished bores, machined faces, threads and corrosion-sensitive surfaces during packaging and transport. Confirm packing method, part identification and delivery documents with the customer. Inspection sampling, witness points and any independent certification requirements are project-specific, not universal claims for all mining components.
Mining Equipment Parts Manufacturing Processes
Casting Crusher, Mill & Mining Machine Components
Sand casting and other suitable casting routes can produce crusher-related components, heavy housings, bearing supports, pump cases, mill liners and selected wear parts. Material and method are chosen around cavity design, casting section, expected loading, alloy requirements and quantity.
Complex cast surfaces and wear profiles are assessed together with molding, feeding, cooling and finishing allowances. Critical mounting faces, bores and holes are machined where required; as-cast dimensions should not be represented as finished CNC tolerances.
Forging Shafts, Pins & Heavy-Duty Connectors
Open-die forging or closed-die forging can be considered for suitable alloy-steel shafts, pins, connectors, rings and related load-bearing blanks. Examples relevant to mining include breaker rod pins and drivetrain parts requiring a specified forged condition.
Forging route and subsequent CNC machining depend on the approved geometry, steel grade, required heat treatment and quantity. Not every crusher hammer, bucket tooth or conveyor part is a forging; select its route based on the actual drawing and operating demands.
Heat Treatment for Strength, Hardness & Toughness
Heat treatment can establish specified hardness, strength or toughness for selected cast and forged mining components. The required cycle varies by alloy: manganese-steel castings, high-chromium iron, steel shafts and structural castings should not be treated as one material family.
Confirm treatment condition, distortion allowances and the necessary acceptance checks before production. Hardness profiles and microstructure tests are requested when relevant to the grade and project specification, not advertised as standard for all jobs.
CNC Machining for Fits, Threads & Mounting Features
CNC machining provides the specified finished features on mining castings, forgings and metal blanks. Typical work includes bearing bores, shaft seats, keyways, liner fixing holes, flange faces, tapped holes, pump interfaces and gear mounting features.
Machining planning identifies robust datums, stock allowance, tool access and the sequence of operations. Final dimensional checks focus on drawing-defined fits, coaxiality, position and functional mounting surfaces.
Sheet Metal Fabrication for Guards & Enclosures
Sheet metal fabrication can be appropriate for selected conveyor guards, dust-system covers, protective enclosures, brackets and duct-related components used around mining and mineral-processing machinery. Cutting, forming and welding follow the supplied drawings.
Sheet thickness, joints, mounting points, access panels and site corrosion requirements should be defined. Fabricated guards and frames are distinct from cast crusher bodies or forged transmission parts; a mixed assembly may need several manufacturing routes.
Surface Protection for Mining Equipment Metal Parts
Surface treatment may include specified blasting, painting, coating or other suitable finishes for mining equipment brackets, housings, guards and machined parts. Coating selection depends on atmospheric moisture, chemical exposure, handling damage and temperature.
A surface finish cannot replace the bulk-alloy hardness or microstructure needed for severe abrasive impact. Wear-resistant liners and chocky bars are primarily selected by material and wear design; protect machined or non-wear surfaces according to the drawing and coating specification.
