Example Embodiment

[0011] by figure 1 It can be seen that a horizontal sand mill in this embodiment includes a feeding pump, a frame 1, a motor fixed on the frame 1, a main shaft 3 connected to the motor 2 through a pulley, and a grinding cylinder 4. In this embodiment In the example, the feeding pump adopts a gear pump or a pneumatic diaphragm pump, and the feeding amount can be adjusted by the feeding pump. The grinding cylinder 4 and the main shaft 3 are connected by a bearing, and a sealing ring is arranged at the bearing connection. The grinding cylinder 4 is composed of a grinding outer sleeve 5, a grinding middle sleeve 6 and a grinding inner sleeve 7. The grinding inner sleeve 7 is fixed in the grinding In the cavity of the sleeve 6, a cooling water channel 8 is formed between the grinding outer sleeve 5 and the grinding middle sleeve 6. The two ends of the grinding outer sleeve 5 are fixedly connected with the two ends of the grinding middle sleeve 6. The inside of the main shaft 3 is ho...

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

(1) 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. (two), background technology: [0002] The horizontal sand mill is to use 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 stirred together by the high-speed rotating disperser, so 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 separa...
