Background
The existing wet ball milling and crushing equipment comprises a grinding cylinder body, a stirrer or a disperser which is arranged on the grinding cylinder body and connected with a rotating shaft, and a separator which is arranged on a material discharging hole in the grinding cylinder body. When the separator adopting the centrifugal principle works, the disperser and the separator connected with the main shaft rotate at high speed, the grinding balls are distributed near the inner wall of the grinding cylinder, less grinding balls are distributed around the separator in the middle of the grinding cylinder, and only the ground materials can enter the discharge hole from the separation hole on the separator under the action of centrifugal force during separation. When the grinding device is in a static state, such as stop operation or initial operation, as the disperser and the separator are not rotated, the grinding balls are deposited at the lower part of the grinding cylinder under the action of gravity, the separator is immersed by the grinding balls, part of the grinding balls can enter the separation holes of the separator, and part of the grinding balls are discharged from the discharge holes when the grinding device is reused, so that the quantity of the grinding balls in the grinding cylinder is reduced, and the grinding efficiency is further influenced.
In order to prevent the grinding balls from entering the separation holes on the separator when the separator is at rest, the length of the separation holes is increased, as in the invention patent of a stirring ball mill with the Chinese patent document number of CN101385989A, the separation holes are arranged into a spiral structure, and the length of the separation holes is increased, so that even if the separator is immersed with the grinding balls when the separator is at rest, the grinding balls are not easy to enter the separation holes due to the bending structure of the separation holes and are discharged through the discharge holes when the separator is in operation. Although the above-described structure partially solves the problem that the grinding balls are discharged through the separation holes, the processing is difficult due to the complicated structure of the separator. Meanwhile, the dynamic balance of the separator during high-speed rotation is not easy to control, and the service life is influenced; meanwhile, the separation path of the separation holes with the spiral structure is long, so that the separation holes are easy to be blocked, and the separation efficiency is influenced.

The ball mill centrifugal separator is used for separating materials ground into smaller diameters from a separation grinding medium from grinding slurry. That is, the desired material is separated from the separation grinding media and larger diameter material particles.
The centrifugal grinding separator is used for separating grinding media from grinding slurry and comprises a separation outer sleeve 1 and a separation inner cylinder 2 arranged in the separation outer sleeve 1, wherein the separation inner cylinder 2 is provided with an inner cylinder separation hole 21; the separation sleeve 1 is provided with a sleeve compound hole 11 which enables grinding media to move outwards and grade materials during rotation, a separation cavity 3 which is sealed in the axial direction is arranged between the separation inner cylinder 2 and the separation sleeve 1, and the separation cavity 3 is respectively communicated with the sleeve compound hole 11 and the inner cylinder separation hole 21.
Specifically, the separation inner cylinder 2 includes a cylindrical inner cylinder body having an inner cylinder receiving chamber 23 provided in the center axial direction thereof for receiving the separation drive shaft 5 and communicating with the inner cylinder separation hole 21. The separation drive shaft 5 is provided with a discharge channel 51, which discharge channel 51 communicates with the separation chamber 3 via an inner cylinder separation bore 21.
When the number of the outer sleeve composite holes 11 is two or more, the outer sleeve composite holes 11 are uniformly distributed on the same circle with the separated outer sleeve axle center as the center of a circle.
The outer sleeve composite hole 11 and the inner cylinder separating hole 21 are respectively in a strip shape, and the lengths of the outer sleeve composite hole 11 and the inner cylinder separating hole 21 are the same in general cases, so that balance is easier to keep and manufacturing is easier.
The outer sleeve composite hole 11 and the inner cylinder separation hole 21 are obliquely arranged, and the included angle a between the radius of the outer sleeve composite hole and the radius of the inner cylinder separation hole and the radius of the hole center are 30-45 degrees.
The separating inner barrel comprises a free end and a limiting end, and the limiting end is provided with a first step 22 for limiting the separating sleeve 1. The side wall of the inner cylinder accommodating cavity 23 of the free end is provided with a second step 24 matched with the separation driving shaft 5. The bottom of the inner cylinder accommodating cavity 23 is provided with a fixing hole 25 for fixing the separation driving shaft 5 and the separation inner cylinder 2 through a fixing bolt.
The inner sides of the two axial ends of the separation sleeve 1 are provided with a sleeve fixing groove matched with the inner cylinder fixing groove on the separation inner cylinder and a fixing pin 4 matched with the inner cylinder fixing groove and the sleeve fixing groove after assembly.

And during high-speed rotation, the outer sleeve composite hole 11, the inner cylinder separation hole 21 and the discharge channel 51 form negative pressure, so that materials with smaller diameters can be sucked into the outer sleeve composite hole 11 and discharged through the discharge channel 51, and materials with larger diameters and the grinding medium A are left outside the separation sleeve 1, thereby realizing separation, avoiding blockage caused by the grinding medium distributed near the separation device during separation, and being shorter in separation channel path and higher in separation efficiency.
