feeder to the primary jaw crusher, the crushed material is sent to the secondary jaw crusher to be crushed again. The crushed material is sent by belt conveyor to vibrating screen to be separated. The material, whose size is suitable for the feed size of the sand making machine, can be sent to the sand making machine. The unsuitable material should be sent back to the secondary jaw crusher to be crushed again. The crushed material from the sand making machine is sent back to the vibrating screen to be separated. The suitable separated sand, which is the final product, should be sent to the sand washing machine to be cleaned, and then sent by the belt conveyor. The unsuitable separated sand should be sent back to the sand making machine to be crushed again. The producing line forms two closed cycles. The producing line can be changed according to the customers?requests.

When you need a truly massive jaw unmatched in reliability, high capacity, and high productivity, you need a Zenith. Zenith's range of large model jaws includes PE600×900，PE750×1060,PE900×1200,PE250×1200 to suit your particular heavy duty, high volume crushing application. Compare a Zenith jaw crusher with any other jaw crusher on the market. Immediately you’ll see this machine was built for demanding production, strength and a lifetime of dependability.

Jaw crusher features:

1. Huge oversized heat treated shafts forged of special alloy to handle overloads and hard material.

2. Extra large, radial thrust tapered roller bearings absorb and withstand extreme shock, radial and thrust loads and offer substantially more bearing life than competitive models.

3. Much heavier, stronger, massive one piece frame, stress-relieved for optimum reliability.

4. Toggle bearing wedges for easy in, easy out bearing replacement.

5. Hardened barrel wear liners protect the pitman.

6. Replaceable toe wear liners on swing and stationary jaw.

7. Larger stroke, deeper crushing motion, steeper nip angle means higher capacity and greater throughput.

8. One piece cast pitman stands up to the most demanding crushing applications.

1. A high crushing ratio and production efficiency

——the connection of higher turning speed and stroke makes the rated power and passing capacity improved greatly and the crushing ratio and capacity increased.

2. Less spare part consuming and low operation cost

——advanced crushing principal and technical data, reliable operation and low operation cost. All parts of the crusher have anti-wearing protection, which can make the life time of spare parts increased by 30% and the maintenance costs decreased to the lowest. The crusher avoids the disadvantages of impact crusher like low average crushing ratio, large energy consumption, fast abrasion of hammer, impact plate and lining board.

3. between-layer pressuring crushing and better finished product shape.

——The crusher adopts between-layer pressuring crushing principal and the suited turning speed, not the traditional single particle crushing principal. The special crushing cavity can makes the crusher crush materials selectively, thus the proportion of fine product and products of cubic shape be increased distinctly and products of lump size decreased by a large extent.

4. Hydraulic pressure protection and hydraulic pressure cavity clearing, high automatization and less stop production and repairing time.

——the discharge opening adjusted by hydraulic pressure and overload protection makes performance of the crusher increased by a large extent, the maintenance and operation easier, the repairing time shorter; the bidirectional metal releasing hydraulic pressure vat makes slab pass through crushing cavity; the crusher can discharges materials automatically when the hydraulic pressure works under the conditions of iron passing and instantaneous overloading, thus there is no trouble of stopping the crusher to discharge materials by hand.

5. Thin oil lubrication makes the life time increased.

——Unique design of thin oil lubrication system prolongs life time of the crusher, high performance and not touchable labyrinth airproof part blocks off the dust and remove the common disorders like the mixture of oil and water in spring cone crusher.

6. Manifold crushing cavity

——It is only need to change fixed cone lining board and movable cone lining board; the type of crushing cavity can be changed from standard coarse cavity to short head fine cavity, which can meet various kinds of need.

7. Easy maintenance and operation.

——all parts of HP cone crusher can be assembled, disassembled and repaired from the top and side part, including the fixed cone and movable cone. For the changing no need to disassemble the crusher body and fasten the bolts. Hydraulic motor makes the performance of crusher better.

8. The crusher can provide customers a higher capacity, better product shape, and easy be operated
