Refrigeration crusher can be widely used in pharmaceutical, food, chemical industry, national defense scientific research and other industries of material crushing, especially for heat sensitive materials, precision chemical industry, Chinese and Western medicine, animals and plants, and materials that are tough and can not be crushed at room temperature. Cryogenic comminution means that the above substances are frozen below the brittle point by liquid nitrogen, and then crushed to the required fineness in the cryogenic comminuter, and the original ingredients will not be destroyed. Moreover, flammable and explosive materials at room temperature can also be crushed at low temperature, and the effect is more remarkable.
In the process of material crushing, the cold source of the freezing crusher system constitutes a closed-circuit circulating system, which makes full use of energy and saves energy consumption: the temperature of the cold source used for crushing can be reduced to negative 196 degrees. According to the temperature of the material's brittle point, the temperature can be adjusted during the crushing process, and the optimum crushing temperature can be selected to reduce energy consumption: the fineness of crushing can reach 10-700 meshes, and even reach micron mu. Equal fineness: liquid nitrogen is used as grinding medium to complete the comprehensive effects of ultra-low temperature grinding, explosion-proof and oxidation-proof of materials.
Cautions for safe operation of freezing crusher
1. Before use, check whether all fasteners of the machine can be tightened and whether the belt can be tightened.
2. The direction of the spindle must match the arrow direction shown on the shield. Otherwise, it will damage the machine and possibly cause personal injury.
3. Check whether the electrical appliances are in good condition.
4. Check whether there are metal and other hard impurities in the crushing room of the machine. Otherwise, the cutter will be damaged and the operation of the machine will be affected.
5. Material must be checked for purity before crushing. No metal and hard impurities are allowed to mix in, so as not to damage the tool or cause extinction accidents.
6. The oil cup on the machine should be injected with smooth oil regularly to ensure the normal operation of the machine.
7. Stop feeding before shutdown. If it does not continue to be used, it is necessary to clean up the legacy inside the machine.
8. Check regularly whether the cutter and screen can be damaged or not. If there is any damage, it should be replaced immediately.
9. Use the opportunity to grasp the tiny vibration, we must tighten the connecting handle of the cover to prevent accidents.
