How is the gyratory crusher specification expressed?

Gyratory crusher, beginning for 1898, due to the reliable, large capacity, until now still widely used in mineral processing plants and other industrial sectors. Its specifications are expressed in terms of the width of the ore and the discharge port. For example, the 500/70 type gyratory crusher has a feed opening width of 500 mm and a discharge opening width of >75 mm. Domestic specifications include: PX500/75 rotary crusher; PX700/130 rotary crusher; PX900/160 rotary crusher; PX1200/180 rotary crusher; PX1500/180 rotary crusher; PX1500/300 rotary crusher machine. Among them: P stands for broken and X stands for spiral.

1. What is the working principle of the rotary crusher?

The principle of the crusher is the same as that of the jaw crusher , but the difference is that the crushing chamber is an annular space formed between the crushing cone and the fixed cone. At any instant, a part of the material is crushed, and the opposite side is crushed. A part of the material is discharged downward at the same time, which belongs to the continuous working system.

2. What should I pay attention to when switching back to the crusher?

After the crusher enters the normal crushing work, the following items must be observed and observed during operation: (1) Check the operation, there should be no abnormal knocking sound inside the crusher. Special circumstances should be stopped immediately. The grain size of the ore should not be more than 0.8 times that of the ore supply. The lower part of the discharge chute and the broken cone should not be blocked by the ore. Otherwise, the ore will be lifted by the broken cone to enter the eccentric shaft, causing an accident; (2) Pay attention to the oil pump The operation, often check the oil flow indicator, oil temperature and oil pressure indications. After the oil passes through the cooler, the temperature should not be higher than 45 ~ 53 ° C, the return oil temperature should not be higher than 60 ° C, and the oil is supplied to the upper suspension device on time; (3) Pay attention to check the tightness of the V-belt, use the thumb Press the V-belt to measure the tension. If the pressure is not more than >1.5cm, the tension is appropriate (measurement must be before or after parking). Check for cracks, and pay attention to the fact that the V-belt should not be glued. (4) Always check whether the connecting pin between the beam, the middle frame and the base is loose and the clearance is equal to >15.0mm along the circumference; (5) Check each part linings for loose, missing and severe wear; (6) to strictly check the mine situation, and to prevent the hammer, drill a top metal objects into the crushing cavity; (7) accidents during operation, such as ore chute was Block, the oil is stopped or the oil temperature exceeds 60 °C and the bevel gear has a knocking sound. It should be disposed of immediately according to the prescribed procedures.

Two Dimensional Movement Mixer

EYH two-dimensional movement mixer is mainly composed of three parts such as the drum, oscillating frame and machine frame. The drum is installed on the oscillating frame, supported by four rollers and positioned axially by two catch wheels. In the four supporting rollers, the two driving wheels are pulled by the rotation power system to make the drum turn. The oscillating frame is driven by a group of crank rocker mechanism, which is installed on the machine frame. The oscillating frame is supported on the machine frame by the bearing assembly.

Features:

The drum of the EYH two-dimensional movement mixer can carry out two movements simultaneously: one is the rotation of the drum and the other is the oscillation of the drum along with the oscillating frame. While the materials to be mixed carry out rotation, turning and mixing along with the drum, they also make reciprocating mixing movement along with the oscillation of the drum. Under joint action of the two movements, the materials are sufficiently mixed within a short time. The EYH two-dimensional movement mixer is suitable for mixing all powder and granular materials.
