Main structure and working principle of calcium carbonate grinding mill

The structure of the calcium carbonate grinding mill is mainly composed of a main machine, an analyzer, a fan, a finished cyclone separator, a fine powder cyclone separator and a duct. Among them, the main machine is composed of a frame, an inlet volute, a blade, a grinding roller, a grinding ring, a casing and a motor.

During work, the material to be pulverized is fed into the machine from the feeding hopper on the side of the main casing, and is revolved around the vertical axis by means of a grinding roller device suspended on the main stand of the main machine, while rotating itself. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring, so that the blade shovel the material to the grinding roller and the grinding ring, and achieves the purpose of pulverizing the material by rolling rolling of the grinding roller.

Wind selection process: After the material is ground, the fan blows the wind into the main casing, blows up the powder, and sorts it through the analyzer placed above the grinding chamber. The coarse and coarse material falls into the grinding chamber and re-grinds. The airflow entering the cyclone collector conforms to the specification, and is collected and discharged through the powder discharge pipe, which is the finished product. The air volume is returned to the fan by the return air pipe at the upper end of the large cyclone collector. The air path is circulated and flows under the negative pressure state. The increased air volume of the circulating air path is partially discharged through the abandoned pipeline between the fan and the host, and enters the small cyclone collection. The device is cleaned.
