The laboratory sander is a kind of grinding and dispersing equipment. According to the characteristics of continuous processing and discharging of materials, the fineness of boredom is determined by the configuration of rotor structure, etc., which increases the production efficiency. It can be divided into many different styles according to different structures, and its uses will also be different. The adaptability of materials is wide.

The temperature of the grinding slurry during the pre dispersion stage should be well controlled. If the temperature of the slurry is too high due to the pre dispersion time process, it is necessary to cool the slurry before passing through the sand mill. Sometimes its high temperature may also be due to the excessive amount of grinding media being loaded, and the amount of grinding media loaded can be appropriately reduced. When the temperature is too high, a chiller can also provide circulating cooling water below 10 degrees Celsius for cooling.

The temperature of the slurry during the pre dispersion stage is not very high, but once it passes through the sand mill, the temperature of the slurry in the grinding chamber quickly exceeds the protection temperature, causing the protective shutdown of the laboratory sand mill. When encountering this situation, based on the knowledge of chemical engineering principles, we can know that under certain conditions such as slurry viscosity, initial temperature, grinding medium loading amount, and motor speed, The temperature rise of the grinding slurry is proportional to the time it stays in the grinding chamber. Therefore, when encountering this situation, we can appropriately increase the speed of the feed pump, shorten the residence time of the slurry in the grinding chamber, reduce the heat generated per unit time, and thus reduce the temperature of the grinding slurry.
