Buffering bolt sealing device for ball milling machine

Abstract

The invention relates to a buffering bolt sealing device for a ball milling machine. The buffering bolt sealing device comprises a milling machine substrate and a milling machine barrel; the milling machine substrate is connected with the milling machine barrel through a buffering bolt; and a pressing nut is assembled on the buffering bolt. The buffering bolt sealing device is characterized in that a sealing ring is sleeved on the buffering bolt on the lower surface of the milling machine barrel; a lug boss is arranged on the lower surface of the sealing ring; a rubber ring pressing cover is sleeved on the lug boss; a spring cushion is arranged on the lower surface of the rubber ring pressing cover; and the pressing nut is assembled on the buffering bolt below the spring cushion. With the adoption of the structure, the binding faces of the sealing ring and the milling machine barrel are more compact after the end face of the sealing ring is deformed. Furthermore, the air tightness manner for sealing is adopted, so that dust can be prevented from leaking from the end face of the milling machine barrel. Therefore, the buffering bolt of the milling machine can be sealed in all directions, so that the social environment can be protected, and the cement milling rotation rate is improved.

Description

Technical field [0001] The invention belongs to the technical field of ball mills for cement production, and particularly relates to a ball mill grinding bolt sealing device. Background technique [0002] Currently, the cement industry uses Ball mill, without roller press system, the largest grinding ball diameter in the coarse grinding chamber of the ball mill When the mill is running, the large grinding ball has a greater impact on the liner of the mill barrel and the bolts of the liner. Coupled with the finer cement powder, dust leakage from the bolt holes of the ball mill is more serious, which affects the social environment. Summary of the invention [0003] In order to solve the technical problems existing in the known technology, the present invention provides a ball mill grinding bolt sealing device with simple structure, convenient installation, good sealing performance and improved cement mill operation rate. [0004] The technical solutions adopted by the present invent...

Problems solved by technology

[0002] Currently, the cement industry produces cement with Ball mill without roller press system, the maximum ball diameter in the coarse grinding chamber of the ball mill When the mill is running, the large grinding balls have a great impact on the lining plate of the mill shell and the lining plate bolts. In addition, the cement powder is relatively fine, and the ash leakage from the grinding bolt holes of the ball mill is serious, which affects the social environment.
