Wet type ball mill discharge particle uniformity detection device

Abstract

The utility model relates to a device for detecting uniformity of particles discharged from a wet ball mill, which belongs to the field of ball mill wet material detection equipment. It is characterized in that: the sampling sieve (9) is slidably installed on the slide rail mechanism (5) in the middle of the frame (1) through the translation and turning mechanism (4), and the feeding mechanism (3), drying mechanism (8) and washing Mechanisms are respectively arranged above the sample sieve (9), the weighing mechanism (7) is arranged under the sample sieve (9), and the weighing mechanism (7) and the feeding mechanism (3) are respectively arranged on the frame (1 ), a drying mechanism (8) is arranged above the weighing mechanism (7), and a water tank (6) is arranged at the lower part of the rack (1) of the sampling sieve (9). The present invention can conveniently and timely control the feeding amount of the ball mill and the grinding time of the stones through the discharge detection of the discharge port of the ball mill, thereby improving the phenomenon of uneven particle size in the working process of the ball mill.

Description

technical field [0001] The utility model relates to a device for detecting uniformity of particles discharged from a wet ball mill, which belongs to the field of ball mill wet material detection equipment. Background technique [0002] The ball rate mill is a very important equipment in the mineral processing equipment, and it is the key equipment for the ore to be crushed after being crushed by the crusher. The ore is mainly ground in the barrel of the ball mill by the impact force, grinding force and extrusion force, so the size of the ore ground is very critical to the beneficiation process. If the grinding is sufficient, it will save a lot of cost for the beneficiation process and increase the income for the enterprise. If the grinding particle size of the ball mill is too large for the mine, the dissociation is not sufficient, and the grade and recovery of the selected concentrate are low. [0003] Among them, the analysis of the factors causing the uneven particle siz...

AI Technical Summary

Problems solved by technology

[0004] 1. The moisture content of the grinding material is too high, and "full grinding" occurs when the moisture content is too high;

[0005] 2. When the temperature in the ball mill is too high, it will cause "ball wrapping"

[0007] Although the above three methods can control the discharge particle size of the ball mill to a certain extent, they are only roughly fine-tuned without precision. You can only manually change the running speed of the ball mill, change the amount of feed, output, and water. The amount of change is unknown and cannot meet the standard of real industrial automation control
