Jaw Crusher Parts

Jaw crushers are designed to exceed the primary crushing needs of customers in the mining, quarrying and recycling industries. These machines are amongst the most advanced and reliable in the market and are highly productive in a variety of applications.

Features:
1. It adopts world-level manufacturing technology and high-end manufacturing materials.
2. More advanced movable jaw assembly makes it more durable. The movable jaw assembly uses high-quality steel casting and drives through two large-sized cast steel flywheels. In addition, the heavy eccentric shaft also adopts forging stock which makes series jaw crusher have extraordinary reliability.
3. The bearing pedestal adopts unitary cast steel structure. The unitary cast steel bearing pedestal can ensure comprehensive fitting with the crusher rack, and at the same time, greatly increase the radial strength of the bearing pedestal, whereas split type bearing pedestal does not have these advantages.

A jaw crusher comprises several main components, including the crushing chamber, the moving jaw, and the fixed jaw. These parts help the jaw crusher crush rock and other materials. Here are the critical parts of a jaw crusher and their functions:
Front frame, Lower Moving jaw, Upper wedge, Frame bolt, Filling wedge, Fixed wedge, Jaw die bolt, Pitman eye protection plate, Disc spring package, Flywheel, Upper Cheek plate, Eccentric shaft, Upper Fixed jaw, Pitman bearing, Upper Moving jaw, Pitman, Center wedges, Frame connecting rods, Lower Cheek plate, Side plate, Lower Fixed jaw, Toggle seat, etc.

Working principle:
The elector motor drives the belt and belt wheel to make the movable jaw to move up and down through the eccentric shaft, and then movable jaw goes up, the angle between the toggle pate and the movable jaw is bigger, thus pushing the movable jaw to get close to the fixed jaw, and at the same time, the materials are crushed or smashed, thus reaching the goal of crushing; when the movable jaw goes down, the angle between the toggle pate and the movable jaw is smaller, under the effect of the draw bar and the spring, the movable jaw moves always from the fixed jaw, and then the crushed materials will be discharged out from the lower mouth of the crushing chamber. With the continuous rotation of the elector motor, the movable jaw of the crusher will do periodic motion to crush and discharge the materials, thus realizing mass production.

The Handling Materials and Application of Jaw Crusher:
Jaw crusher is mainly used for the medium-granularity crushing of all kinds of ores and large materials in mine, metallurgy, building material, highway, railway, water conservancy and chemistry. The maximum compression strength of the materials to be crushed is 320MPa.

The Advantages and Benefits of Jaw Crusher:
Jaw crusher is a crushing machine that is researched and developed very early. With simple and solid structure, reliable work, easy maintenance and repair and low production and construction fees, it has long been widely used for the coarse, medium and fine crushing of various kinds of ores and rocks whose compression strength is 147~245MPa in many industrial departments such as metallurgy, chemistry, building material, power plant and transportation.

Pump parts

Industrial Pump Parts and Castings — Precision Components to Customer Specification

SMI manufactures industrial pump parts and castings to customer drawing and technical specification — covering pump housings, volute casings, impellers, end covers, bearing brackets and associated precision machined components. Production spans casting, precision machining and surface treatment, with finished components supplied to pump manufacturers and industrial equipment OEMs worldwide.

SMI’s capability in this area is defined by its casting and precision machining depth, not by a standard product catalogue. Every component is produced to the customer’s own engineering drawing or specification — including material grade, dimensional tolerances, surface finish and inspection requirements.

Manufacturing Capability

Casting

Pump housings, volute casings and impeller bodies are among the more geometrically complex castings in industrial equipment manufacture — requiring accurate core setting, controlled solidification and consistent wall thickness to meet the hydraulic and pressure requirements of the finished pump. SMI’s casting capability covers grey iron, ductile iron, carbon steel, stainless steel and speciality alloys for corrosion-resistant applications.

Precision Machining

Cast pump components require precision machining of mating faces, bore dimensions, bearing seats and sealing surfaces to achieve correct assembly fit and hydraulic performance. SMI’s machining capability covers the full range of pump component features — flanged faces, impeller wear ring bores, shaft seal housings and bolt patterns — to the tolerances specified in the customer’s engineering drawing.

Corrosion-Resistant Materials

Pump applications in seawater service, offshore environments and chemical process industries impose material requirements beyond standard grey or ductile iron. SMI supplies pump components in duplex stainless steel, super duplex, Hastelloy-equivalent alloys and other corrosion-resistant specifications for customers operating in aggressive fluid environments. Material selection is confirmed at the enquiry stage based on the fluid handled, operating temperature and pressure, and customer material specification.

Component Types

Component Typical Materials Key Manufacturing Operations
Pump housing / volute casing Grey iron, ductile iron, carbon steel, stainless steel Casting, flange face machining, bore machining
Impeller Grey iron, stainless steel, duplex stainless Casting, balance machining, wear ring bore
End cover / bearing bracket Grey iron, ductile iron, carbon steel Casting, bearing seat machining, seal housing
Wear rings Bronze, stainless steel, hard iron Turning, grinding to close tolerance
Shaft sleeves Stainless steel, hard chrome Turning, grinding, surface treatment
Stuffing box / seal housing Grey iron, stainless steel Casting, precision bore machining

Application Areas

Industrial Process Pumps

Centrifugal pumps, multistage pumps, gear pumps and screw pumps used in general industrial process applications — chemical processing, power generation, oil and gas upstream and downstream, and heavy industrial cooling and fluid transfer systems. SMI supplies cast and machined components for both single-stage and multistage configurations to customer drawing.

Marine and Offshore Pumps

Seawater cooling pumps, fire pumps, ballast pumps and general service pumps for marine and offshore applications impose specific material and dimensional requirements driven by classification society rules and the corrosive nature of the service environment. SMI has experience supplying pump components in seawater-resistant alloys for marine customers, with material certification supplied as standard.

Oil and Gas Industry Pumps

Upstream and downstream oil and gas applications include high-pressure injection pumps, pipeline transfer pumps and produced water handling systems — all of which involve aggressive fluid environments and high reliability requirements. SMI’s corrosion-resistant material capability is directly relevant to this sector.

Special Fluid Applications

Chemical process pumps handling aggressive or reactive fluids require material selection beyond standard iron and carbon steel. SMI can manufacture pump components in stainless steel, duplex stainless and higher-alloy specifications for customers whose process fluids impose specific corrosion or contamination requirements.

Planetary Reducer

Planetary Reducer and Precision Gear Components — Custom Manufacturing to Customer Specification

SMI manufactures planetary reducers and precision gear components to customer drawing and technical specification — covering gear cutting, precision machining, heat treatment and assembly. Planetary reducer configurations cover a wide ratio range with multiple output shaft options, supplied to industrial equipment manufacturers and OEM customers in heavy machinery, mining, energy and marine sectors.

As with all SMI mechanical component supply, finished products are produced to the customer’s own engineering drawing or specification. SMI does not supply standard catalogue reducers — every configuration is engineered to the specific ratio, torque, shaft geometry and mounting requirements of the customer’s application.

SMI planetary reducer precision components- output flange, ring gear, planet carrier assembly and planet gear shaft, machined to customer specification
SMI planetary reducer component set – output flange, internal ring gear, planet carrier and planet gear shaft assembly, all precision machined to customer drawing and specification

Planetary Reducer — Configuration and Capability

A planetary gear system consists of a central sun gear, a set of planet gears rotating around it, a ring gear enclosing the assembly, and a planet carrier transmitting the output torque. The compact, coaxial layout of the planetary system delivers high torque density relative to its physical size — making it the preferred reducer configuration for space-constrained and high-torque applications across heavy industry.

Standard Configuration Range

Parameter Range Notes
Gear ratio 3:1 — 400:1 Single and multi-stage configurations
Output torque Up to 2,000 N.m Higher torque on request
Output shaft type Square, hexagonal, flange Custom shaft geometry available
Custom configurations All parameters To customer drawing and specification

Custom configurations outside the standard range — higher torque ratings, alternative shaft dimensions, modified mounting geometry or specific material grades — are available on request. SMI application engineers will confirm the appropriate configuration at the enquiry stage.

Components Manufactured

The image above shows four core planetary reducer components manufactured by SMI — illustrating the precision machining capability applied across the full component set:

  • Output flange / planet carrier flange — precision bolt circle and mating face, machined to assembly drawing tolerances
  • Ring gear — internal gear cutting to specified module, tooth profile and accuracy grade
  • Planet carrier assembly — bearing bore machining, planet pin holes and structural body
  • Planet gear shaft assembly — external gear cutting, shaft journals and spline features to drawing

Herringbone Gear Capability

In addition to planetary reducer components, SMI manufactures herringbone gears — a double helical gear configuration where two sets of oppositely angled helical teeth are combined side by side. The herringbone geometry cancels the axial thrust loads inherent in single helical gears, allowing high power transmission without the substantial thrust bearing requirements that helical gears impose. This characteristic makes herringbone gears particularly well suited to high-torque gearboxes in heavy machinery and marine propulsion applications.

Herringbone gears are more demanding to manufacture than equivalent spur or helical gears — requiring precise alignment of the opposing helical flanks at the centreline junction. SMI’s gear cutting capability covers this geometry, with finished gears supplied to the accuracy grade and material specification required by the customer’s application.

Applications

  • Mining and mineral processing equipment — conveyors, mills, hoists and crushing machinery
  • Heavy industrial machinery — presses, mixers, extruders and material handling equipment
  • Energy sector — wind turbine pitch and yaw drives, oil and gas pumping systems
  • Marine propulsion and auxiliary machinery — where herringbone gear capability is directly relevant
  • Construction equipment — tracked vehicles, cranes and lifting machinery
  • Agricultural and forestry machinery — high-torque drive systems

OEM and Custom Supply

SMI’s planetary reducer and gear component manufacturing service is available to equipment manufacturers requiring:

  • Component supply to drawing — individual gear components produced to the customer’s engineering drawing or CAD model
  • Complete reducer assembly — fully assembled and tested planetary reducer to customer specification
  • Gear cutting to specification — module, tooth profile, accuracy grade and material to customer requirement
  • Heat treatment — case hardening, through hardening or nitriding to specified surface hardness and case depth
