Cylindrical ball mill

Abstract

The invention relates to special high-temperature conveying equipment which is designed based on the improvement of the technological requirements of magnesium smelting and other special industries, in particular to a cylindrical ball mill. The cylindrical ball mill comprises a support, wherein a turnover speed-down motor and a rotary rack are fixed on the support, and the rotary rack is provided with a speed-down motor and a grinding drum which is driven by the speed-down motor and is provided with a manual cap opener. The cylindrical ball mill is characterized in that a bilayer water tank is arranged at the lower part of the grinding drum, a protective cover is additionally arranged on the upper edge of the bilayer water tank, a far infrared temperature measuring sensor is arranged at the rear part of the grinding barrel, and a photoelectric encoder is arranged behind the rotary speed-down motor. The cylindrical ball mill disclosed by the invention has a novel structure and is favorable for realizing a high-efficiency, uniform and consistent cooling manner and an automated temperature measuring and controlling manner.

Description

technical field [0001] The invention relates to a special high-temperature conveying equipment designed and improved for magnesium smelting and other special industrial process requirements, in particular to a cylindrical ball mill. Background technique [0002] At present, the grinding time of the cylindrical ball mill is generally long, sometimes more than 100 hours. Since the temperature of the material will continue to rise during the grinding process, when the temperature exceeds the required value, the characteristics of the material will change, and the material in the cylinder will be broken. If it is scrapped, it will cause a great waste of human and financial resources, so the cooling and temperature control of the material during the grinding process is very important. The cooling and temperature control method used in the past cylindrical ball mill is to spray cooling water on the outer wall of the grinding cylinder. After a period of time, stop the machine and o...

AI Technical Summary

Problems solved by technology

The disadvantages of this cooling and temperature control method are: first, the cooling efficiency is low. When grinding, the material is generally at the bottom of the grinding cylinder, while the cooling water is sprayed on the side; second, the cooling water is sprayed from a row of holes to the On the outside of the grinding cylinder, the uniformity and consistency are poor, and the fluctuation of water pressure and water flow directly affects the cooling effect; third, due to the long grinding time, it is necessary to stop the machine several times during the grinding process of a cylinder of materials to test the temperature and wait, less efficient
