Product introduction

The jaw crushing machine consists of two jaw plates, the dynamic jaw and static jaw.The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate (stationary jaw), the other is the mobile jaw plate (dynamic jaw), the position is inclined, with the fixed jaw plate forms the upper big lower small crushing cavity (working chamber).The movable jaw plate moves periodically to the stationary jaw plate, sometimes apart, sometimes close.When separated, the material enters the crushing chamber and the finished product is discharged from the lower part.When close, the material between two jaw plates is compressed, bent and split.Widely used in mine smelting, building materials, roads, railways, water conservancy and chemical industries and other industries of various ore and bulk material crushing.The maximum compressive strength of the crushed material is 320Mpa.

Product Advantages

 

The crushing ratio is an important measurement index for measuring the jaw crusher. The crushing ratio of the jaw crusher is the ratio of the raw material granularity to the crusher's product accuracy. It indicates the degree of reduction of raw materials after crushing. After the ore is crushed, the particle size becomes smaller, and the ratio of the particle size before the ore is broken to the broken particle size is called the crushing ratio. It represents the multiple size reduction after the ore is broken. There are several ways to calculate the crushing ratio:

1. Calculate the maximum grain size by using the maximum grain size before crushing and the maximum grain size after crushing. This calculation method is commonly used in the design of concentrators in China because the jaw crusher is used to determine the maximum grain size of the crusher. width

2. The ratio of the effective width of the feed port of the jaw crusher to the width of the discharge port

Certain jaw crushers, the size of their discharge is not determined by the size of the discharge port.

3, using the average particle size before and after crushing ore, also known as the average crushing ratio

Features

1, low noise, less dust.

2. The crushing ratio is large and the product size is uniform.

3, simple structure, reliable work, low operating costs.

4. Lubrication system is safe and reliable, parts are easy to replace, and equipment maintenance is simple.

5, deep crushing cavity and no dead zone, improve the feeding capacity and output.

6. Energy-saving equipment: Single-machine energy-saving 15% to 30%, system energy-saving more than doubled.

7. The discharge outlet has a wide range of adjustment to meet the requirements of different users.

operating principle

When the jaw crusher is working, the movable jaws make periodic reciprocating motions to the fixed jaws, sometimes approaching and sometimes leaving. When approaching, the material is crushed, split, and impacted between the jaws; when it is removed, the broken material is discharged from the discharge opening by gravity.
In the process of breaking large stones into small stones, the first crusher is usually a “main” crusher. The longest and most solid crusher is a jaw crusher. When feeding the jaw crusher, the material is poured from the top inlet into the crushing chamber containing the rake teeth, and the rake teeth force the material against the wall of the chamber and break it into smaller stones. An eccentric shaft is supported for the movement of the caries, and the eccentric shaft penetrates the frame of the fuselage. Eccentric motion is usually generated by flywheels fixed at both ends of the shaft. Flywheels and eccentrically supported bearings often use spherical roller bearings, which must withstand large shock loads, abrasive sewage, and high temperatures.
