TSP is calcium carbonate referred to, is made from natural carbonate minerals such as calcite, marble, limestone grinding together. Heavy calcium powder is commonly used inorganic filler, widely used, can provide general Gaifen different size requirements needed superfine heavy calcium carbonate, calcium carbonate ultra-fine wet grinding, surface modification of ultrafine heavy carbonate calcium.
Heavy calcium powder production methods are dry and wet, the current domestic product to take all the dry production. Press grinding fineness different GCC divided into four different sizes: solo powder (95% passing 200 mesh), Flying powder (99% passing 325 mesh), three fly powder (99.9% passing 325 mesh) and four Fly Powder (99.95% through 400 mesh) for different industrial sectors.
8-10 tons of heavy calcium powder 325 mesh technology and production processes:
The first stage: Shattered
Natural carbonate minerals such as calcite, marble, limestone and other bulk materials through the crusher to be able to enter the mill feed fineness (15mm-50mm).
 Phase II: flour
After crushing small pieces of material by hoist to the hopper, and then by their uniform quantitative feeder into the grinding mill grinding indoors.
Powder processing generally used LM vertical roller mill, MTW European version of the mill, TGM Super Pressure Trapezium Mill; ultrafine powder processing generally used LUM superfine vertical mill, HGM medium-speed micro-grinding.
The third stage: Classification
Grinding material through the separator after grading, unqualified powder will be returned to the host after the election, re-grading the powder machine grinding.
Fourth stage: Set pink
In line with the fineness of the powder with the air through the pipe into the dust collector separated collection, finished powder collected through the discharge port by the delivery device to the finished product silos, and then unified with the loaded tanker powder or automatic packer for packaging.
Depending on the fineness of materials and needs, applications, needed for the production process are subject to change, need flexible operation. For details, please contact our online customer service.
Attachment: different fineness heavy calcium applications:
GCC due to the different grinding fineness is divided into:
Solo powder (200 mesh, D95): used in the production of anhydrous calcium chloride, is the main raw material dichromate auxiliary materials, glass and cement production of soda production. In addition, for supplies and poultry feed.
Flying powder (325 mesh, D99): is the production of anhydrous calcium chloride and glass and other raw materials, rubber and paint white filler, as well as construction materials.
Three fly powder (325 mesh, D99.9): used as plastics, paint putty, paint, plywood and paint filler.
Four fly powder (400 mesh, D99.95): used as a filler wire insulation layer, molded rubber products as well as asphalt filler made of linoleum.
