Steel ball grinding body classifying device applied to cement ball mill and classification method of steel ball grinding body classifying device

Abstract

The invention provides a steel ball grinding body classifying device applied to a cement ball mill which belongs to the technical field of cement ball mills. The invention further relates to a classification method of the steel ball grinding body classifying device applied to the cement ball mill. A discharging chute (2) is arranged below a receiving hopper of the steel ball grinding body classifying device applied to the cement ball mill; a sorting component (3) is arranged at the side surface of the receiving hopper (1); a long roller I (4) of the sorting component (3) is connected with a driving motor I (6); a long roller II (5) is connected with a driving motor II (7); a gap part (8) is arranged between the long roller I (4) and the long roller II (5); and the width size of the gap part (8) is set as a structure which is gradually increased from one end close to the receiving hopper (1) to one end far away from the receiving hopper (1). The steel ball grinding body classifying device and the steel ball grinding body classification method applied to the cement ball mill provided by the invention can realize automatic classification of steel balls according to the diameter of different steel balls, can realize precise control on classification of the steel balls, and improves the classification efficiency.

Description

Technical field [0001] The invention belongs to the technical field of cement ball mills. More specifically, it relates to a classifying device for steel ball grinding bodies for cement ball mills. The invention also relates to a method for classifying steel ball grinding bodies for cement ball mills. Background technique [0002] In the grinding process of a cement factory ball mill, steel balls are required to have a certain diameter and steel balls of different diameters are required to maintain a certain proportion. After a long time grinding process of steel balls, the damaged steel balls need to be cleaned up and new steel balls should be made up at the same time. In the grinding process of a ball mill in a cement factory, the best grinding effect is not only affected by the loading of steel balls, but also related to the diameter of the steel balls. The diameter of the steel ball (ball diameter) in the cylinder of the general pulverizer ranges from 15 to 80 mm. If the cy...

Problems solved by technology

At present, most of the cement industry still uses manual sorting methods for grinding body sorting, which takes a long time for sorting and is labor-intensive, which affects production.

Or use equipment such as steel ball screening machines for steel ball sorting, but it is cumbersome to replace the screen, and it is not suitable for large-diameter steel ball screening, and the operation and maintenance costs are relatively high
