JC Series Jaw Crusher

Introduction:

Type: Crushing machine

JC series jaw crusher applies finite element analysis and successfully developed on the basis of millions of our jaw crusher design and manufacturing experience. 

Compared with traditional jaw crusher, JC series jaw crusher pay more attention to the details. Adopts high-strength material, first-class manufacturing process, the series leads to the advantage of excellent -strength structure, reliable equipments, higher crushing ratio, bigger capacity and lower cost. 

Raw materials:Limestone, shale, calcium carbide, carbide slag, bluestone, basalt, river pebble, copper, ore, etc

Capacity:50-1500TPH

Max feeding size:≤425-1250mm

Application:Mining, metallurgy, building material, highway, railway, chemical, etc.

Technology advantages

1.Solid structure 

There are two types of machine frame: welded type and assembled type. The former is for small and middle size, and the latter is for big size.The welded type adopts large arc fillet and low stress welding method, greatly reduces the concentration stress which ensures rack equal strength in all directions, high impact resistance, even force, low failure rate.

Assembled type uses advanced modularization and non-welded frame structure design of high fatigue strength and high reliability. Meanwhile machine assembly design makes transportation, and installation more convenient, especially suitable for installation in narrow and small places like undermine and high altitude mining.

2.Extraordinary cavity design 

Symmetrical V formed design, toggle of large obliquity, long stroke, reasonable rotor speed, allow larger materiel block in feeding, higher productivity, homogeneous output granule, less attrition for jaw plate.

3.Long working life of the heavy-duty movable jaw assembly 

The whole set of heavy movable jaw plate integrates forged heavy eccentric shaft, high quality bearing of heavy loading, the design of movable jaw plate optimized by finite element analysis. These features assure the stroke resistance and stability. Labyrinth seal and centralized lubricating system prevent the greese of bearing not to be contaminated, and assure the easy lubrication which results in longer function and more stability.

4.Shield design for the movable jaw 

Heavy protective shield installed above the movable jaw plate protects internal bearing from damage caused by material falling down in feeding moment.

5.Overall bearing support 

One piece cast of bearing seat assures good match with frame, and avoids unnecessary radio direction pression for bearing in fastening process which occurs usually to composed bearing seat. Therefore, Bearing function is more stable.

6.Convenient particle size adjustment 

JC jaw crusher adopt mechanic or hydraulic device to adjust discharge opening. Compared with shim, adjustment by double block is simpler, saver, faster, and reduces downtime.

7.Integrated motor installation 

Integrative installation of motor chassis and crusher frame not only saves installation space of jaw crusher but also reduces the length of Vee belt. Thanks to synchronous movement of crusher frame, motor chassis and motor. Adjustable motor chassis can realize the adjustment of Vee-belt's tensile force to make the Vee-belt more durable.

8.Shock absorption design

The crusher is fixed by the device of special rubber shock absorption, which absorbs effectively the its vibration at the peak point and meanwhile, allows crusher to displace in vertical and horizontal direction. In this way, the shock to foundation would be reduced.

Working principle:

The motor drives belt and pulley. The movable jaw swings up and down before and after through the eccentric shaft. When the movable pushes the movable jaw plate to the fixed jaw plate, the material is crushed or split into pieces. When the movable jaw and movable jaw plate springs back in the effect of eccentric shaft, the material previously have been crushed discharges from the discharge opening of the lower part. With the motor continuously rotating, the movable jaw breaks and discharges material periodically to achieve mass production.

Compared with traditional jaw crusher, JC series jaw crushers pays more attention on details in the process of design and manufacture. It uses high-strength materials, advanced manufacturing technology, which contributes to the stronger structure, higher reliability, larger crushing ratio, higher productivity, lower cost.

Technical parameter

Note:The capacity is total tons per hour passing through crusher at open circuit when crushing medium and below hardness material and bulk density with 1.6x10³kg/m³. Capacities are relative to physical character and type of feeding,feeding size and composition and so on.
