how to choose a 325 mesh calcium carbonate grinding mill?
325 mesh calcium carbonate calcium carbonate powder is widely used. Which calcium carbonate grinding mills are suitable for producing 325 mesh calcium carbonate powder? Below we will try to find the answer for you.The models mainly involved in calcium carbonate grinding mill is YGM Raymond mill and HGM micro powder grinding mill.
Kindly noted, the calcium carbonate powder we mentioned is ground calcium carbonate powder.Aboutprecipitated calcium carbonate(light calcium carbonate powder,PCC) we will analyze in detail in subsequent articles.
Ground calcium carbonate powderalso namedheavy calcium carbonate powder,AbbreviationGCC.It is made of high-quality limestone and processed into a white powder by a lime mill. Its main component is CaCO3.
HGM micro powder grinding mill is the new type mining equipment for making micro powders, fine powderswhich is widely applied in the industries of metallurgy, mining, chemistry, cement, construction, refractory materials, ceramics, and so on.The purpose of the micro powder grinding millis for super-fine grinding materials with hardness less than 9 in Moh's scale and humidity less than 6 percent such as kaolin, limestone, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds.
Calcium Carbonate Powder Making Machine Production line: consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems.
When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.
The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the airflow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.
According above information we can see, if you only want to produce 325 mesh calcaium cabonate powder and the application industry does not require high quality powder, Raymond mill is cheaper and is a better choice. But if your downstream industry has high requirements for powder quality, you also have the need to produce higher fineness powder, and your country is environmentally demanding, and you don't want noise, HGM micro powder grinding mill will be the best choice.

After coarse crushing, the material is fed into the ball mill through a controllable feeding device. The grinding medium in the mill repeatedly impacts and grinds the material by virtue of the kinetic energy obtained when the mill rotates. The crushed material is discharged into the suction tank through the tail of the ball mill, and then transported to the classifier for classification by negative pressure. The qualified fine powder is collected by cyclone collector or dust collector, The coarse particles after classification are discharged from the lower end of the classifier, and then re-enter the ball mill for crushing through the feeding pipe.
Note: The production capacity is closely related to the particle size, specific gravity, hardness, moisture and other indicators of the raw materials. The above parameters are for reference only, please consult our engineers for details.
