Sand mill for producing coating

Abstract

The invention discloses a sand mill for producing coating, and particularly relates to the technical field of coating production grinding equipment. The sand mill comprises a barrel, the side face of the barrel is fixedly communicated with a slurry input pipe, the outer surface of the barrel is fixedly communicated with a grinding medium input pipe, a cooling water input pipe and a cooling water output pipe, the interior of the barrel is rotatably connected with a rotary drum through a bearing seat, the inner wall of the rotary drum is rotatably connected with a main shaft through a bearing seat, the surface of the main shaft is fixedly connected with a rotary disc, the side face of the rotary drum is fixedly connected with a control sleeve, and a first control groove is formed in the control sleeve. The grinding efficiency is improved, the grinding time is saved, the energy consumption is reduced, the equipment is convenient to use and popularize, the grinding speed and the grinding efficiency of the sand mill are controlled, the equipment is convenient to maintain, the coating production cost is reduced, coating particles and grinding media are filtered, the coating purity is improved, the coating production continuity is ensured, and the energy consumption is saved.

Description

technical field [0001] The invention relates to the technical field of coating production and grinding equipment, more specifically, the invention relates to a sand mill for producing coatings. Background technique [0002] The sand mill is currently the grinding equipment with the widest material adaptability, the most advanced, and the highest efficiency. The grinding chamber is the narrowest, the gap between the levers is the smallest, and the grinding energy is the most intensive. With the high-performance cooling system and automatic control system, it can realize continuous grinding of materials. Processing continuous discharge greatly improves production efficiency. Paint, traditionally known as paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The ...

Problems solved by technology

[0003] However, in actual use, most of the existing sand mills are designed to rotate in a single shaft inside the grinding chamber, resulting in low grinding efficiency, high energy consumption, and high production costs. At the same time, the existing sand mills need to manually control the transmission belt. , and then adjust the spindle speed, it is not convenient to realize automatic production, and the production efficiency is low. At the same time, the grinding fluid produced by the traditional sand mill is easy to mix with the grinding medium, which is not easy to remove, resulting in low purity of coating production
