Basic introduction to rotary crusher

Whether it is a gyratory crusher or a cone crusher, its advanced point also happens to be its complex point, which is why relatively speaking, only large key projects will usually consider the use of gyratory crusher, rather than jaw crusher. However, the conventional crushing equipment or stone shredder compared to it, but there are incomparably.

Before the crusher starts, first of all to the hydraulic cylinder inside filling oil. Operation procedure of oil filling: press the selection switch on the electric control box in the "working" position, start the oil pump motor, and then drive the hydraulic pump to run. The main purpose of the crude oil filter is to protect the hydraulic pump from the direct damage of large particle impurities. In order to make the hydraulic pump oil absorption capacity is not affected, the oil filter installed on the oil suction circuit is generally designed to be more than twice the hydraulic pump flow.

The hydraulic oil then passes through the fine oil filter with the sending device, which shall have certain strength; And its maximum pressure drop cannot exceed 0.35mpa; Its transmitting device is a pressure relay. When it is used for a long time, due to excessive accumulation of impurities in the oil on the filter screen, the oil pressure drop is too large. At this time, the pressure relay will send an alarm signal to prompt to clean the filter screen. Gyratory crusher

Press the "moving cone rising" button, the directional valve solenoid Gl is energized, the oil reaches the bottom of the hydraulic cylinder through the directional valve and the hydraulic control one-way valve, thus the moving cone begins to rise. When it reaches the predetermined working position, the oil pump motor can be stopped, the pressure of the hydraulic system can be maintained at a certain level, and the crusher can start to work normally.
