Horizontal sand mill

Abstract

The invention discloses a horizontal sand mill which comprises a base, a motor, a main shaft and a grinding cylinder. The motor is fixed on the base, the main shaft is hollow and is connected with the motor through a belt pulley, cooling oil chambers are fixedly arranged around the main shaft, a cooling water flowing passage is intermediately formed, a plurality of grinding rods are fixedly arranged around the outer wall of a grinding inner sleeve, a cooling water pipe is arranged in the grinding inner sleeve, a U-shaped spiral water channel is fixedly arranged around the outer wall of the cooling water pipe, and a feeding hole and a discharging hole are arranged on a grinding outer sleeve. In the mill, both-end-surface mechanical sealing is adopted and a sealing ring is arranged at the joint of a bearing and a shaft. By adopting the technical scheme of the invention, the defects caused by overhigh temperature generated when a traditional horizontal sand mill runs are effectively overcome, the sand mill is stable and reliable to run, and the production quality and the operation efficiency are greatly improved.

Description

technical field [0001] The invention relates to a high-efficiency wet-process ultra-fine grinding and dispersing machine for the production of paint, dye, paint, ink, medicine, magnetic powder, ferrite, photosensitive film, pesticide, papermaking and cosmetics, etc., and specifically relates to a horizontal type sand mill. Background technique [0002] The horizontal sand mill uses the material pump to input the solid-liquid phase mixture material that has been pre-dispersed and wetted by the mixer into the inner grinding sleeve, and the material and the grinding medium in the inner grinding sleeve are agitated by the high-speed rotating disperser, thereby Make the solid particles in the material and the grinding medium have more intense collision, friction and shearing effects to achieve the purpose of accelerating the grinding of fine particles and dispersing aggregates. The ground and dispersed material passes through the dynamic separator to separate the grinding medium...
