Product details
Calcium carbonate is an inorganic compound that is the main component of limestone and calcite.
Calcium carbonate is divided into two categories: heavy calcium carbonate and light calcium carbonate. Due to their different particle size, crystal shape, and interface properties, heavy calcium carbonate and light calcium carbonate have vastly different reaction characteristics. Therefore, there are many different varieties and uses of calcium carbonate, such as active calcium carbonate, papermaking calcium carbonate, plastic calcium carbonate, nano calcium carbonate, edible calcium carbonate, medicinal calcium carbonate, chemical calcium carbonate, and coating calcium carbonate.
The wide application of calcium carbonate:Usually used as a filler, it is also widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, building supplies, food, medicine, textiles, feed, toothpaste, etc. As a filler, it increases the volume of products and reduces production costs. Used in rubber, it can increase the volume of rubber, improve the processability of rubber, play a semi reinforcing or reinforcing role, and adjust the hardness of rubber.
The production process of heavy calcium carbonate includes:
Firstly, manually select calcite, limestone, chalk, shells, etc. transported from the quarryTo remove vein stones; Then use a crusher to roughly crush the stones, and then use calcium carbonatepulverizerGrind to obtain fine limestone powder, and then use a classifier to grade the powder. The powder that meets the particle size requirements is packaged and stored as a product, otherwise it is returned as calcium carbonate powderpulverizerGrind the powder again.
HGMseriescalcium carbonatepulverizerMainly suitable for ultrafine powder processing of non flammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤ 6, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, zeolite, gypsum, alum, graphite, fluorite, phosphate ore, potassium ore, pumice and more than 100 other materials. The fine powder products processed by the grinding machine can be adjusted between 325-3000 mesh, and the output can reach 0.5-12 tons per hour.
calcium carbonatepulverizerWorking principle:
During operation, the main motor drives the spindle and turntable to rotate through a reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway.
Large pieces of material are crushed into small particles by a hammer crusher and then sent to the storage bin by a hoist. After passing through a vibrating feeder and an inclined feeding pipe, the material is evenly delivered to the upper part of the turntable's bulk tray.
The material disperses around the circumference under the action of centrifugal force and falls into the raceway of the grinding ring, where it is impacted, rolled, and ground by the ring rollers. After being processed into powder through three layers of raceway, the high-pressure fan sucks in external air into the machine through suction and brings the crushed material into the powder selection machine.
The rotating impeller inside the powder selector causes the coarse material to fall back and be re ground. The fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged by the discharge valve at the bottom, which is the finished product. The airflow with a small amount of fine dust is purified by the pulse dust collector and discharged through the fan and muffler.
Equipment composition of calcium carbonate powder mill:
The complete configuration includes a hammer crusher, bucket elevator, storage bin, vibrating feeder, micro powder mill host, variable frequency classifier, dual cyclone powder collector, pulse dust removal system, high-pressure fan, air compressor, and electrical control system.
Calcium carbonate powder millPerformance characteristics：
1.**The**
When the fineness of the finished product and the power of the motor are the same, this calcium carbonatepulverizerMore than twice the output of air flow mills, agitation mills, and ball mills.
2.Long service life of vulnerable parts
Calcium carbonate powder millThe grinding roller and grinding ring are forged from special materials, greatly improving their utilization. When the fineness of the material and finished product is the same, thispulverizerLonger service life of wear parts compared to impact crushers and turbine crushers2-5 times longer, with a lifespan of up to 2-5 years.
3.High safety and reliability
calcium carbonatepulverizerDue to the absence of rolling bearings and screws in the grinding chamber, there is no problem of bearings and their seals being easily damaged, and there is no problem of screws becoming loose and damaging the machine.
4.High product fineness
The fineness of calcium carbonate processed by a calcium carbonate grinding machine can reach a one-time levelD97≤5μm。
5.Environmental protection and cleanliness
useGrinding equipmentThe pulse dust collector in the middle captures dust and uses a muffler to reduce noise, which has the characteristics of environmental protection and cleanliness.
