Ball mill grinding door stopping and correcting system and method

Abstract

The invention discloses a ball mill grinding door stopping and correcting system and method. The system comprises a bottom plate, one end of the top of the bottom plate is fixedly connected with a first fixing plate, one side of the top of the first fixing plate is fixedly connected with a first fixing cylinder, the end, away from the first fixing plate, of the top of the bottom plate is fixedly connected with a second fixing plate, the side, close to the first fixing plate, of the top of the second fixing plate is fixedly connected with a second fixing cylinder, and a cylinder body is rotationally connected between the first fixing cylinder and the second fixing cylinder. A steel column is arranged at the position of a mill door of a ball mill, and a proximity sensor matched with the steel column is arranged on the bottom plate, so that the ball mill can be automatically stopped when the mill door is located right above after central control equipment issues a shutdown command, the maintenance time can be saved, auxiliary equipment such as an oil station and the like is prevented from being started and stopped again, and meanwhile, related human input is saved; in addition, the sampling representativeness and accuracy of a scram mill are improved, and practical application is facilitated.

Description

technical field [0001] The invention belongs to the technical field of ball mills, and in particular relates to a ball mill door stop system and a method thereof. Background technique [0002] In the existing life, the cement ball mill is mainly used in the grinding of finished products and raw materials in cement plants. It is also suitable for grinding various ores and other grindable materials in industrial and mining enterprises such as metallurgy, chemical industry, and electric power. Cement mills have strong adaptability to materials. , Continuous production, large crushing ratio, easy to adjust the fineness of the grinding product, etc. The cement ball mill can be used for both dry and wet production, and can also be used for grinding and drying at the same time. The material is fed through the feeding device. The feeding hollow shaft spirally and evenly enters the first warehouse of the ball mill. There are stepped lining boards or corrugated lining boards in the wa...

Problems solved by technology

[0003] However, in the actual use of the cement ball mill, especially when the grinding is stopped for maintenance and the mill is stopped for sampling, it is often necessary to stop the grinding door of the ball mill at the top. Due to the inertia of the mill, the position of the ball mill after it stops is not directly above, which is inconvenient to open and close the mill door, and also affects the representativeness of emergency stop sampling, which is not conducive to practical application
