Jaw Crusher

Seiko produced

Easy to install

WHITE LAI Jaw crusher has a range of bolt-on options, including an on-board motor base, and guarding for the flywheel and drives made from specially developed composite materials, which makes the unit simple to install as a crusher only or as a complete module in a new or existing plant.

The most versatile primary crusher

WHITE LAI PE Series jaw crushers are most commonly used as primary crushers, to make the first step of size reduction. In some cases the jaw crushers is used to produce final end product but in most cases the jaw crusher is used to prepare the feed for the secondary crusher in a crushing and screening process.

1．Flywheel

Balances inertia, Promotes smooth operation.

2．Frame

Heavy-duty design, Steel plate welded construction, Welded by CO2 shield arc process, Stress relieved after fabrication.

3．Swing Jaw & Main Bearing Housings

Allows removal from frame as an integral subassembly, Permits onsite substitution of a changeover unit in the event of bearing damage, Swing Jaw is a robust steel casting with fully machined face to support swing jaw plate.

4．Bearings

ZWZ or SKF heavy -duty self aligning double row bearings on swing jaw and main frame, Bath oil lubrication ensures positive lubrication (optional).

5．Eccentric Shaft

Forged from hardened and tempered chrome molybdenum steel, particularly large diameters to suit heavy -duty application.

7．Cheek Plates

Manganese steel castings allow easy replacement.

8．Jaw Plates

High manganese steel castings can be reversed allowing extended life.

13．Toggle Plates of cast iron increase the safety factors.

Designed to shear protecting crusher components if noncrushable object is introduced to crusher (i.e. Steel).

Product Structure

WHITE LAI PE series Jaw crusher are premium class crushers due to their design as well as to the materials that are used to produce them. attention has been paid to even the smallest details,so as to ensure the highest possible functionality and reliability,without any compromises.

Benefits

Product durable design

1.High strength and firm structure

Welded frame ensures equal strength in all directions and excellent durability against shock loads.

2.Durable moving jaw assembly

The moving jaw assembly is made of high-quality cast steel and droved by two massive cast steel flywheels. A very large eccentric shaft forging and four large spherical roller bearings that are all of the same size ensure the greatest reliability even under the most severe crushing conditions.

3.Finite element design

WHITE LAI jaw crusher have gone through the FEM technology analysis,which ensures all stress levels inside within appropriate range and guarantees the high strength structure and stable performance of jaw crusher.

4.Selected large spherical roller bearings

All WHITE LAI jaw crusher incorporate larger and sturder spherical roller bearings than competitors'comparable size,thus largely improve its rotation speed.The grease-lubricated bearings are kept free from contamination by means of well-proven labyrinth seals,ensure the reliability that WHITE LAI PE Series jaw crushers are known for.

5.Single piece cast steel frame bearing housings

The single piece cast steel frame bearing housing ensure a perfect fit to the crusher frame.They also prevent unnecessary loads to the frame bearings that are common woth 2-piece frame bearing housings.

Structural Design

6．High production

Deep symmetrical crushing chamber and optimized nip angle maximizes size reduction and improve production capacity.

7．High reduction ratio

Wider intake opening offers possibility to handle larger feed sizes.

8．Easy to install

The Jaw crusher has a range of bolt-on options, including an on-board motor base, and guarding for the flywheel and drives made from specially developed composite materials, which makes the unit simple to install as a crusher only or as a complete module in a new or existing plant.

9．Safe to operate and maintain

WHITE LAI PE jaw crusher is designed to be safe to operate and maintain. There are a limited number of service points and they can be accessed easily and safely. Lifting tools for items such as jaw dies, cheek plates and the toggle plate are supplied with the crusher to guarantee safe maintenance procedures and to ensure the safety of both crusher operators and maintenance crew.
