The composition types of ultra-fine pulverizers and other types of pulverizers are basically similar, and it is further innovated and modified on that basis. In general, micro-grinding is mainly composed of main engine, blower, ultra-fineness analysis machine, finished cyclone dust collector, bag filter and connecting air duct. Users are equipped with lift, storage bin, electric control cabinet and electromagnetic as needed. Add equipment to the powder machine, crusher, etc. In the Ultrafine Mill chamber, the grinding roller assembly is suspended on the grinding roller hanger through the cross-arm shaft, the grinding roller hanger is fixedly coupled with the main shaft and the blade holder, and the pressure spring is tightly pressed by the tension rod in the grinding roller shaft chamber. On the outer end of the suspension wall, with the cross-arm shaft as the fulcrum, the grinding roller is pressed tightly on the inner surface of the grinding ring by the spring pressure. When the motor passes the transmission, the blade mounted on the blade holder is synchronized with the grinding roller. Rotating, the grinding roller rotates around its own axis and revolves while rolling inside the grinding ring. The analyzer drives the impeller of the analyzer through the motor transmission device. The analyzer adjusts the speed to achieve the purpose of milling.
The micro-grinding work process is also relatively simple, mainly because the bulk material is crushed and sent to the storage bin by the hoist, and then the electromagnetic vibrating feeder is evenly sent into the main machine grinding chamber, and the material entering the vertical roller mill is shoveled by the blade. After entering the grinding roller and the ring, it is crushed and crushed. The fan blows the wind into the grinding chamber, and blows the powder into the analysis machine for sorting. The fineness of the grinding chamber is not up to the fineness. The powder enters the finished cyclone collector with the airflow. The fine powder is separated from the air and discharged from the discharge port, which is the finished product, and the air is returned to the fan from the upper return air duct. The air path is cyclic and under negative pressure. flow.
In the grinding chamber, due to the certain moisture content of the material to be ground, a certain amount of heat will be generated during the grinding to cause the water vapor to evaporate, and the flanges of the whole machine are not tightly connected to seal the outside air, so that the circulating airflow increases. The grinding machine is guaranteed to work normally under the negative pressure state, and the increased gas flow is discharged into the bag filter through the residual gas pipe between the fan and the main machine, and is purified and discharged into the gas.
From this point of view, the principle of ultra-fine grinding and other grinding equipment have the same function, but its function is superior to other grinding machines, the efficiency is greatly improved, and the applicable fields of production products will be more extensive.
