PE Series stone Jaw Crusher machine

JAW CRUSHER INTRODUCTION

The jaw crusher is the workhorse of the crushing industry for mining, construction, and demolition recycling. SANDMAN  jaw crushers are industrial-grade, continuous-duty machines. They take large pieces of rock, ore, concrete, or other materials, and crush them down to smaller sizes, for further processing in a secondary crusher or sand maker.

STANDARD FEATURES

★Complete and ready to run including jaw crusher, belts, and motor.

★Over-sized bearings and castings, robust construction, long-wearing cast manganese steel jaw plates

★Sizes: 6”x 10” through 24” x 30″ jaw opening

★Discharge size: ranges from 1/4” minus through 4″ minus

★Electric and diesel engine power options are available

★All wear and replacement parts are available

★Manufacturing time needs about 30 days

★The swing jaw undergoes two types of motion: one is a swing motion toward the opposite chamber side (called a fix jaw plate due to the action of a toggle plate), and the second is a vertical movement due to the rotation of the eccentric(called a movable jaw plate). These combined motions compress and push the material through the crushing chamber at a predetermined size.

★While the Jaw Crusher is mainly used as the first stage of material reduction in systems that may use several crushers to complete the circuit, the Jaw Crusher has also been used as a second-stage crushing unit. Depending on the application requirements, Jaw Crushers can be used in stationary, wheeled portable, and track-mounted locations. The Jaw Crusher is well suited for various applications, including rock quarries, sand and gravel, mining, construction and demolition recycling, construction aggregates, road and railway construction, metallurgy, water conservancy, and chemical industry.

HOW A JAW CRUSHER WORKS

A Jaw Crusher uses compressive force to break material. The crusher's two jaws achieve the mechanical pressure dies, one fixed and the other movable. These two vertical manganese jaw plates create a V-shaped cavity called the crushing chamber, where the top of the crushing chamber is larger than the bottom. Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 24 x 36‘’ Jaw Crusher measures 24" from jaw plate to jaw plate at the top opening or gape opening and 36” across the length of the two jaw plates.

The narrower bottom opening of the crushing chamber is used to size the discharge material. A toggle plate and tension rods hold the pitman tight near the bottom of the moving swing jaw. The toggle plate is designed to perform like a fuse and protect the crusher if an uncrushable material enters the crushing chamber.                            

Since the crushing of the material is not performed in one stroke of the eccentric shaft,  weighted flywheels are attached to the eccentric shaft and powered by a motor. The flywheels transfer the inertia required to crush the material until it passes the discharge opening.

If you can explain how a nutcracker works you can essentially envision the operation of a jaw crusher.

Inside the chamber, there are two jaws. One is fixed while the other constantly moves back and forth. This action compresses the rock causing it to break.

Rocks stay in the jaws until they are small enough to pass through the bottom gap.

FEATURES & BENEFITS

√Rigid one-piece fabricated base frame for unmatched durability and strength

√Massive cast steel for brute shock loads

√Deep crushing chambers and large eccentric shafts offset combined with a steep toggle angle yield more compressive force throughout the crushing chamber

√Large balanced flywheels supply continuous inertia to the crushing action

√The side guard is held in place by bolts pressing a steel plate, making maintenance easy.

√Reversible manganese jaw plates for long-life use

√Toggle plate is designed as a fuse to protect the crusher from a tramp iron event

HOW TO CHOOSE THE SUITABLE MACHINE

To design a suitable machine, please let us know the following information:

1. what kind of stone do you want to crush? limestone? granite? Or others.

2. what's the size of your stone before crushing? how many inches or mm? 

3. how big capacity do you need? 1t/h?10t/h?100t/h?

4. what are your requirements for the final product size? how many inches or mm? 0-5,5-10,10-20mm Or others?

5. Do you only need one set of crushers or a whole crushing line? (Include the feeder, crusher, screen, conveyor, and so on)

6. Do you need a mobile crushing machine or a stationary one?
