Some Elements of Affecting Production of Jaw Crusher


The impact jaw crusher is mainly used for the crushing the medium-hard and hard materials. Its main features are the followings. The upper end slightly tilts to the outside and it is fixed on the front cavity wall of the crusher. The other jaw plate moves back and forth which is called the moving jaw or the jaw tongue. The position of the moving jaw is tilt. The moving jaw forms a trapezoid crushing cavity with the fixed jaw. Since the working area formed by the moving jaw and the fixed jaw mainly contacts with the materials to be crushed, they have very high wearable requirements.

The jaw crusher uses motor as its power. Through the motor’s wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening. Due to its simplicity, reliable performance, easy maintains and repairs and suitable for every kind of rocks, especially the tough rocks, jaw crusher is used until now.

The capacity of the jaw crusher is concerned by many jaw crusher manufacturers and ore producers. So the factors that impact the capacity of jaw crusher plant should be pay attention to by manufacturers and users.

First, the hardness and toughness of material exceed the range of operating instruction manual. If jaw crusher plant is occurred by the conditions above, the specialist suggested replace jaw crusher within specification range. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like concentrator table price, Henan Hongxing is always doing the best in products and service.flotation separation process: http://www.crusher-machine.com/n123.html

The discharge opening is less than specified limits. You should adjust discharge opening according to operation instruction manual. Or change a new jaw crusher with suitable discharge size.

Second, the voltage is too low working site. You should adjust voltage. timely so as to meet requirements of the host machine overloaded.

Third, the gap between moving jaw and bearing is too large after wear and tear, which caused relative rotation of the bearing outer ring. For this situation you should replace bearing or movable jaw.

Besides, more knowledge about the jaw crusher is best way to avoid of impacting the capacity of jaw crusher.

The crushing chamber is a tilt space with different tilt angles, which can form two crushing cavity, namely the coarse crushing cavity and the fine crushing cavity. The butterfly spring is used to achieve the overload protection. Compared with other crusher machines, the impact jaw crusher has the advantages of low production cost and high working efficiency. The impact jaw crusher is generally made of the highly wear resistant manganese steel liner, because the liner of the jaw crusher has very high wear requirements. When the jaw crusher works, there are two jaw plates in the crushing cavity. One jaw plate is fixed which is called the fixed jaw.
