Dear Rizal,

For general fineness (80-400 mesh) of calcium carbonate powder, vertical mill, European type grinding mill (Raymond mill upgrade product), overpressure trapezoidal mill and other equipment can processed.

For ultra-fine calcium carbonate powder processing, LUM ultra-fine vertical mill can be used to produce ultra-fine calcium carbonate powder of more than 1250 mesh, which is used in PE and PP masterbatch, papermaking and other fields.

LUM ultra-fine vertical mill is a new type of ultra-fine grinding equipment designed by Kefid. Based on ordinary vertical mill, it adopts the current Taiwan grinding roller technology and German powder selection technology.

It adopts the principle of material layer grinding, the material has short residence time in the mill, less repeated grinding, less iron content, high whiteness and clarity of finished product; grinding curve of specially designed roller sleeve and liner; it can be ground to the required fineness (0.045-0.02mm) at one time.

2. The powder selection technology is mature, adopting the principle of multi-wheel selection, all the rotors can be frequency-controlled, the fineness of the finished product can be realized within the selected range; and when the finished product with the same fineness, its energy saving is about 30%-50% than that of the ordinary mill.

3. Reliable operation, equipped with mechanical and electronic limit devices to avoid destructive shock and vibration; using PLC/DCS automatic control roller pressure control method, accurate control, no manual operation; vertical grinding roller lubrication station can fully lubricated to prevent oil leakage.

4. Easy maintenance and environmental protection, the grinding roller does not directly contact with the grinding disc, less wear and long life; the grinding roller can be turned over for maintenance, convenient and quick, reducing downtime loss; low vibration, low noise, good overall sealing, no dust spill, clean and environmentally friendly.
