Used Barite Crushing Machine In USA

Used Barite Crushing Machine In USA

USA Used Barite Crushing Machine Cavity Type Selection Principle

There are two types of USA Used Barite Crushing Machine chambers: short head type and standard type. The application of the two chamber types is different. The standard type is used for two-stage breakage and three-stage breakage, and the finished product size is generally larger than 25 mm. It is not used for closed loops in the second stage of breaking. The crushing ratio is 4~6, preferably after screening and breaking. The short head type is used for three-stage breakage, and the finished product has a particle size of less than 25 mm. A closed loop is required, and the crushing ratio is 3~5, which needs to be sieved and broken.

USA Used Barite Crushing Machine Crushing Ratio

  • i=F(80)/P(80).
  • i: crushing ratio. F (80): 80% of the mesh size through which the feed can pass. P (80): 80% of the mesh size through which the discharge can pass.

Feed Particle Size And Abrasiveness

The tight edge feed port of the USA Used Barite Crushing Machine should not be smaller than the maximum feed size. The inlet should not be too large or too small.

The Inlet Is Too Large

  • 1. The material is mainly concentrated in the lower part of the crushing chamber, causing excessive wear of the lower part of the lining plate and low utilization of the lining plate.
  • 2, the crushing ratio is reduced, the USA Used Barite Crushing Machine is low in efficiency and easy to cause the moving cone to rotate.

The Inlet Is Too Small

  • 1. The material can not enter the crushing chamber, the production capacity is seriously shrunk, and the liner of the USA Used Barite Crushing Machine inlet is severely worn or even destroyed.
  • 2. The crushing force fluctuates greatly and the adjustment ring jumps, causing damage to the frame seat cushion, accelerating the wear of the lock cylinder seal and affecting the stability of the USA Used Barite Crushing Machine.

The abrasiveness of the material mainly affects the service life of the broken liner. Appropriate increase of the manganese content of the liner (not more than 20%) can improve the service life of the liner. At present, the liner of ZGMn18Cr2 is used more.

Product Size And Size

The particle size of the product depends on whether the crushing process is open-circuit crushing or closed-circuit crushing, and the discharge opening required to obtain a satisfactory product particle size must be clear. The discharge port here refers to an approximate value, even if the same working condition is the same for two identical USA Used Barite Crushing Machines, the discharge ports are not necessarily the same.

In general, the tight side discharge opening of the USA Used Barite Crushing Machine is equal to the size of the mesh or slightly larger than the average particle size of the desired product. In the case of the product type, the short-head type crushing chamber can obtain the best product type, followed by the standard fine-cavity type, and the larger the cavity type, the less easy to obtain a good product type. In order to ensure good product size, the crushing ratio should be controlled from 3 to 3.5.
