Jaw crushers are equipments which can coarsely and intermediately crush several hard materials by the press and bend of the two Jaw plates. It consists of fixed and movable Jaw plates. When the both plates close to each other, the materials can be crushed, and when separate each other, the smaller materials than discharging open can be sent out on the bottom, the action of crushing is intermittent. The equipment is widely used in industries such as mining-selecting, construction materials, silicate and pottery, because of the advantages of simple structure, reliable operation, crushing hard materials.

Main engine suddenly stops.

The output can't reach original factory standard

Reasons:

1) The hardness or endurance of materials go beyond the range of instruction book

2) Electric motor connects inversely, the main engine works opposite (Jaw crusher rotates clockwise)or the electric's triangle connection is replaced by star connection by mistake.

3) Discharging open is smaller than specified limits

4) Jaw plate moved, the tops of the teeth opposite each other.

5) The voltage of working space is too low

6) Movable Jaw plate and bearing are wear off that the break is too large that the outer ring of bearing comes into relative rotation

Repairing methods

1) Replace crushing material or crush once again.

2) Adjust the motor connection

3) Adjust discharging open to adapt the instruction book and increase the machines used in tiny crushing

4) Check the distance between dental plate and pitch of gear, if not match the instruction book, replace the Jaw plate, adjusting the relative places between fixed and movable Jaw plates make sure that top of the tooth face the tooth root, then fixed in case the shift

5) Raising the voltage of working space to adapt the demand of main engine.
