The existing ball mills mainly adopt a horizontal roller ball mill and a vibration ball mill, but the ball mills have defects, wherein the horizontal roller ball mill has low production efficiency and long discharging time due to low rotating speed; the vibration ball mill has the problems of large vibration noise, incapability of continuous production and low yield. In order to solve the problems of low rotating speed, large vibration noise and the like, a wet ball mill is designed. The wet ball mill is widely applied at present, can be applied to wet grinding of ferrous, nonferrous metal and nonmetal materials, adopts slurry, ball milling medium and steel balls as ball milling substances of the materials, and controls the ball milling substances to move through the ball mill, thereby crushing the materials. The wet ball mill has the characteristics of high production efficiency and low working noise.
For the wet ball mill on the ore grinding production line, the ball mill needs safe and stable production in grinding materials, so that the yield of the wet ball mill can be greatly improved. However, the existing wet ball mill is complex in structure, when materials are processed, if the feeding and discharging speeds are not balanced, the accumulated content of coarse-fraction materials in the cylinder of the ball mill is insufficient, fine-fraction materials subjected to ball milling are not discharged in time, the time of the materials in the equipment is prolonged, the materials are levigated to form over-damage, the particles of finished products are too fine, the over-pulverization phenomenon occurs, the productivity of the ball mill is reduced, and the production cost is increased.

Detailed Description
The specific embodiment of the present invention is shown in fig. 1.
The embodiment provides a take dosing device wet process ball mill, including feed bin 1, screw valve 2, inlet pipe 3, belt weigher feeder hopper 4, belt weigher 5, speed sensor 6, pressure sensor 7, the balance body 8, transportation belt 9, transportation belt support 10, belt weigher installing support 11, converter 12 and ball mill 13.
The material of this embodiment enters the feeding pipe 3 through the bin 1 and controlled by the screw valve 2. In the process of stably conveying materials, the speed measuring sensor 6 and the pressure sensor 7 provide two signals of the running speed of the belt scale 5 and the instantaneous load of the materials for the programmable frequency converter to receive and process, so that the weighing and metering of the materials and the quantitative feeding control of the materials are realized. The material is fed into the barrel of the ball mill 13 by the conveying belt 9, the bearing drives the barrel to rotate, and in the rotating process, the material can be crushed in the barrel of the ball mill due to the falling impact and the self-grinding of the steel balls and the ores.
Because the material is fed continuously, the pressure in the ball mill 13 causes the material in the cylinder to move from the feeding end to the discharging end, and the product is carried out from the discharging part through water flow. And (4) grading the discharged materials by a grader, collecting and packaging qualified products in a collector, and returning unqualified products to the ball mill or performing secondary grinding until the fineness meets the requirement.
In the ball mill of the embodiment, the ball mill 13 can force the lean material and the plastic material to be uniformly stirred and mixed under the wet process, although the time is short, the slurry with uniform components can be obtained, and the particles of the slurry are mainly round particles, but not flaky particles, so that the rapid flowing of the slurry is facilitated. The ball mill is simple to operate, automatic control can be basically achieved through the frequency converter, labor intensity of production workers is reduced, production cost is reduced, and production efficiency is greatly improved.
