Pebble sand making machine is specilized for sand making and shaping. In this text, we will introduce the advantage and disadvantage of pebble sand making machine.

The spiral sand washing machine may fail to discharge material as a result of blade wear, excessive feed, overly fine material, low speed, internal blockages, transmission malfunctions, bearing damage, or motor reducer failure.

The crushers play a vital role in the production of sand and gravel. It has various types and wide utilization. Jaw crusher, cone crusher, impact crusher, sand making machine is widely used.

There are two ways to support swing jaw, i.e. traditional support and external oscillating bar support. The latter is developed on the basis of the former one. Now, let’s give you the detail instruction of these two supports.

Cone crusher has features such as big crushing ratio, high efficiency, low power consumption, and stable operation. This paper will analyze the worn causes of vertical shaft screw thread for cone crusher.

Hammer crusher employs high speed hammer head to generate strong impact force to crusher and grind the limestone. After a long time of service, the machine will be deprived of its normal functions due to the components wearing out, distortion or damage caused by the impact force and friction of the material.

In this text, we will talk about the spare parts of jaw crusher – The Function of Thrust Plate.

The jaw plate wear is mainly shown in the middle and bottom parts of jaw plate, especially 1／3 point is the most serious wear, the upper part is less wear.

Impact crusher rotor is one of the easy worn parts, rotor wear is inevitably to stop the machine to check, which directly affect the production efficiency of impact crusher, so how to prolong the service life of the impact crusher’s rotor?
