product description

The CAM-H series internal classification mill (horizontal classification) is a micro powder production equipment with ultra-fine classification function. It belongs to the same type of machine as the German ZPS and domestic CWJ micro powder machines. This machine is mainly suitable for crushing materials with Mohs hardness below 3.5 and can obtain ultra-fine powder of 5~150um. The large flow of cooling gas can be used for crushing heat-sensitive materials.

Performance characteristics

※ It integrates a mechanical impact ultra-fine pulverizer and a turbine ultra-fine classifier. The crushed materials are affected by the air flow and are forced to be classified by the turbine classifier in the machine. The classification device replaces the screen of the usual pulverizer and can complete micro-grinding at the same time. and micro powder sorting, with high crushing efficiency. 

※By adjusting the speed of the classifying impeller, the particle size of the product can be adjusted without stopping the machine. 

※ When the system is pulverizing, the powerful pulverizing airflow produces a strong cooling function, and the temperature rise is low during pulverizing. It is especially suitable for processing heat-sensitive and fibrous materials, and the product particle size is uniform.

Parts composition

※ This machine is mainly composed of cavity, machine base, grading device, crushing device, high-speed motor, bearing seat and other parts. 

※ The crushing rotor is the main component, including the crushing main shaft, bearing unit, bearing seat, bearing cover, crushing disc, crushing hammer and other components. The classification part mainly includes classification spindle, bearing unit, bearing seat, bearing cover, classification impeller and other components. 

※The feeding unit is mainly composed of a reduction motor, a screw shaft, a feeding hopper and other components. The amount of material added is mainly achieved by adjusting the speed of the reduction motor. working principle: 

※ The inner cavity of the machine body is cylindrical, the upper part is an ultrafine classifier, and the lower part is an ultrafine pulverizer. The crushing chamber is composed of a crushing disc and a grinding block, which is used to crush the materials into fine powder. The grading chamber is composed of a grading impeller, which can divide the fine powder into two specifications: products that meet the standard and products that do not meet the standard. The products that meet the standard are discharged through the discharge pipe. , collected by cyclone collector. Products that do not meet the standard will fall back to the crushing chamber along the inner wall of the cavity and continue to be crushed until they reach the standard. 

※ The grinding disc and the grading impeller are driven by their own driving devices. The speed of the grading impeller is adjustable to adjust the product particle size. The spiral feeding device is located on the inner wall of the machine body and is used to feed materials evenly into the crushing chamber. The amount of material added can be achieved by adjusting the rotation speed.

The complete system mainly consists of a host machine, a cyclone collector, a pulse dust collector, a high-pressure induced draft fan, a discharge valve and an electric control cabinet. The raw materials are sent to the crushing chamber by the screw feeder. The crushed materials are affected by the negative pressure air flow and are forcibly classified by the turbine classifier in the machine. The two processes of micro-grinding and micro-powder sorting are completed at the same time. The finished products are collected by the aggregate system. The tail wind is filtered and discharged by the pulse dust collector.
