Vermiculite is a natural, inorganic, non-toxic mineral that expands under high temperatures. It is a relatively rare mineral and is a silicate. Its crystal structure is monoclinic, and its appearance looks very much like mica. Vermiculite is produced when certain granites are hydrated, and is generally produced at the same time as asbestos. Because vermiculite has the ability to exchange ions, it has a great effect on soil nutrition. During its use, it needs to be crushed with vermiculite grinding production equipment.

The vermiculite powder production line is composed of the main machine of vermiculite grinding production equipment, analysis machine, pipeline device, blower, as well as crusher, elevator, electromagnetic vibration feeder, electronic control motor, etc. that can be equipped according to user needs. After the material is crushed to the required particle size, the material is sent to the storage hopper by the elevator, and then the material is evenly and continuously sent into the main grinding chamber of the vermiculite grinding production equipment through the vibrating feeder. Due to the centrifugal force during rotation, the grinding roller moves towards the grinding chamber. It swings outward and presses against the grinding ring. The blade scoops up the material and sends it between the grinding roller and the grinding ring. The grinding is achieved due to the rolling of the grinding roller. The fine powder after grinding the material is brought into the analysis machine with the circulating air of the blower for sorting. The too fine and coarse material falls back to be reground. The qualified fine powder enters the finished product cyclone powder collector with the air flow and is discharged through the powder outlet pipe. That is the finished product. Because there is a certain amount of moisture in the grinding chamber of the vermiculite grinding production equipment, heat is generated during grinding, the water vapor evaporates, and the pipe interfaces of the whole machine are not tight, and external air is sucked in, which increases the circulating air pressure and ensures that the mill Working under negative pressure, the increased air flow is discharged into the dust collector through the residual air duct, and then discharged into the atmosphere after being purified.
The main selection of vermiculite grinding production equipment is Raymond roller mill, also known as Raymond mill. Raymond roller mill is a new type of mill that replaces ball mill for processing mineral powder. The centrifugal force of the grinding roller of the Raymond mill presses the grinding ring tightly, so when the grinding roller and grinding ring wear to a certain thickness, the output and fineness of the finished product will not be affected. Raymond mill has a long replacement cycle of grinding rollers and grinding rings, thus eliminating the problem of short replacement cycle of centrifugal mill wearing parts. This grinding mill is suitable for grinding non-flammable and explosive materials such as barite, calcite, potassium feldspar, talc, marble, limestone, ceramics, glass, etc. with Mohs hardness less than 7 and humidity below 6%. The particle size of the finished product can be adjusted arbitrarily within the range of 80-400 mesh.
