The Consumable Parts of Portable Jaw Crusher

Apr 01 2015

Consumable parts are these parts that are easy to wear and damage in the working process. Since portable jaw crusher works in the mountainous and hilly areas and materials crushed by it are very hard usually above 350 MPA, the consumable parts of portable jaw crusher are worn quickly. What are the consumable parts of portable jaw crusher? this paper will give you a comprehensive summary.

1. Jaw plate

The jaw plate of portable jaw crusher includes the fixed jaw plate and the movable jaw plate. When the portable jaw crusher works, the movable jaw plate moves to the fixed jaw plate driven by motor and materials between these two plates are crushed and grinded. The jaw plate is made of high manganese steel. Since the abrasion resistance of high manganese steel is poor and the working environment of portable jaw crusher is bad, the wearing of jaw plate is quick. Therefore, the jaw plates of portable jaw crusher need to be replaced regularly.

2. The edge guard board

The function of portable jaw crusher’s edge guard board is to protect the rack wall and to reduce the wear of the rack. The edge guard board is between the fixed jaw plate and the movable jaw plate. It is also made of high manganese steel. In order to ensure the normal operation of equipment, the edge guard board of portable jaw crusher needs to be regularly checked. If the guard is worn, it should be replaced immediately.

3. Bracket

Bracket of portable jaw crusher has two roles. One is the power transmission components of the machine, and the other is the insurance part of portable jaw crusher. During the working process, when there are some materials that can not be crushed entering into the crushing chamber, the bracket of portable jaw crusher will be broken and the portable jaw crusher will stop working to avoid more serious damage. The movement manner of bracket adopts rolling contact. There is a layer of grease on the contact surface of bracket. In the normal operation, there is seldom friction between the surfaces.

4. V-belt

V-belt of portable jaw crusher is the power transmission components. The v-belt connects the motor pulley and grooved wheel, which drives the eccentric shaft to rotate. Then the movable jaw plate can make a reciprocating motion. Since the v-belt is made of plastic material, it is worn very quickly. Therefore, operators should regularly check the wear patterns of the v-belt.
