What’s the calcium micromill liners

Calcium carbonate is made from natural carbonate minerals such as calcite, marble and limestone. It is a commonly used powdery inorganic filler with high chemical purity, high inertness, difficult chemical reaction, good thermal stability, no decomposition below 400

°

C, high whiteness, low oil absorption, low refractive index, soft and dry. It does not contain crystal water, low hardness, low abrasion value, non-toxic, odorless and odorless What is the calcium carbonate micromill liners?

Calcium carbonate Raymond mill is suitable for non-flammable and explosive mining and chemical industry, such as barite, calcite, potassium feldspar, talc, marble, limestone, ceramics, glass, etc., with Mohs hardness not greater than 7 and humidity below 6%. In the building materials, metallurgy and other industries, more than 680 kinds of materials are processed, and the finished product size is arbitrarily adjusted within the range of 100-1250 mesh. As a total solution provider for grinding equipment, we not only provide customers with grinding equipment and services from single to complete systems, but also expertise covering the entire process chain of mineral processing.

The grinding roller shaft of the calcium carbonate Raymond mill is installed on the plum blossom frame, the plum blossom frame is driven by the transmission device to rotate rapidly, the grinding ring is fixed, and the material is fed into the body through the feeder from the side of the body. Grinding between the roller and the grinding ring. The airflow is blown from the lower part of the grinding ring in a tangential direction, passes through a grinding zone between the grinding roller and the disk, and the dust is discharged into the wind classifier in the upper part of the disc grinding machine. There are 3-6 grinding rollers hanging on the plum blossom frame and revolving around the central axis of the machine body. Due to the centrifugal force generated by the revolution, the grinding roller is flared outward, pressing the grinding ring and rolling thereon. The material fed into the mill is scooped up by a blade and fed between the grinding roller and the grinding ring for grinding. The blade is attached to the plum blossom frame, the blade is mounted obliquely, and a blade is placed in front of each roller to allow a flow of material to be continuously fed between the roller and the grinding ring.

The wind classifier is a single or double row impeller classifier driven by a separate motor. In order to improve the classification efficiency and adjust the classification particle size in a wide range, a double-row impeller classifier can be used. The single-row and double-row impellers have a graded particle size between 60% <100 mesh and 95% < 325 mesh, respectively. The higher the rotational speed of the impeller, the finer the fractional particle size. The impeller consists of a number of radial vanes that cause the updraft to produce a rotational motion. The centrifugal force generated by the swirling airflow causes the coarse particles to gather to the outer layer, and finally leaves the airflow and falls to the grinding zone for re-grinding; and the fine-grained grade is discharged into the cyclone collector with the airflow upward, and is discharged from the lower part of the collector, and purified. The airflow enters the blower from the top and returns to the bellows. The entire system operates under negative pressure, and the excess airflow is again cleaned by another cyclone and discharged into the atmosphere.
