An external water cooling pulverizer

Abstract

The invention discloses a water-cooled pulverizer, which includes a motor room, a casing, and a material collection box arranged at the bottom outlet of the casing, and the casing includes an upper hopper, a lower hopper, a crushing cavity, and a movable toothed disc. , and a fixed toothed plate connected to the casing through a hinge, a number of impellers are welded on the movable toothed plate and the fixed toothed plate, the size of the movable toothed plate coincides with the size of the fixed toothed plate, and It includes a cooling water channel arranged between the pulverizer casing and the pulverizing chamber. The pulverizer has a simple structure, firmness, stable operation, good crushing effect, and no dust pollution. It solves the melting phenomenon of heat-sensitive materials during the crushing process, improves the utilization rate of materials, and reduces production costs. The material can be directly discharged from the mill cavity of the main machine, and the particle size can be obtained by replacing the mesh screen with different apertures. Ensure material cleanliness.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to an external water-cooled grinder. Background technique [0002] The pulverizer is a machine for crushing large-sized solid raw materials to the required size. It is suitable for pharmaceutical, chemical, metallurgy, food, construction and other industries, including crushing plastic, copper wire, Chinese herbal medicine, rubber, etc. Due to the high heat generated during the crushing process, some heat-sensitive materials, such as resin powder, white sugar, and salt, will melt, so ordinary grinders are not suitable. In the patent application number 200920084425.X, a high-efficiency water-cooled pulverizer is disclosed. By setting the pulverizer head cover as a double-layer structure, the interlayer is a cooling chamber, and the water inlet and outlet are separately provided on both sides of the cooling chamber. Cooling down the pulverizing chamber solves the problems ...

Problems solved by technology

In the patent application number 200920084425.X, a high-efficiency water-cooled pulverizer is disclosed. By setting the pulverizer head cover as a double-layer structure, the interlayer is a cooling chamber, and the water inlet and outlet are separately provided on both sides of the cooling chamber. Cooling down the pulverizing chamber solves the problems that the existing pulverizing machine cannot work for a long time, the production efficiency is low, and there are many dead spots. In the crushing work, the vibration of the shell is relatively severe, which is easy to cause damage to the cooling chamber. Once there is water leakage in the cooling chamber, it will cause great damage to the high-speed crushing head in the crushing chamber. Security risks
