Calcium carbonate exists as an abundant natural resource in Turkey. Therefore, it can be obtained at low cost, and is one of the available materials for use in the industrial production of plastics, rubber, paint, and so on. Such industrial applications require well-refined and dispersed calcium carbonate particles. These characteristics play a crucial role in calcium carbonate properties and their control is closely related to the method of its production and the process parameters.
Surface modification is a key process in functional powder preparation, which can be commonly classified into three types: chemical, physical and mechano-chemical.Recently, surface modification with a combined action of modifying reagent and the mechano-chemical effect of ultrafine grinding has been intensively studied in the pigment and filler preparation area.
Raymond Mill is widely used in the processing of calcium carbonate, the whiteness of the greatest strengths of the calcium carbonate powder, calcium carbonate powder, natural bluish hue was white parallel fruit and easy to combine with the whitening agent. With calcium carbonate, the source of ore, white in varying degrees by calcite, limestone to marble, calcium carbonate, Whiteness 86% to 93% within the calcium carbonate is a natural ore, mixed with impurities, such The situation with the mine source of calcium carbonate in fine powder or ultra-particle level, white lower 1-2 degrees, so calcium carbonate powder is widely used in paint, chemical and other industries.
At this stage of calcium carbonate powder grinding mill, Raymond mill makes the calcium carbonate powder broader and broader scope.
Calcium carbonate grinding works:
When working host motor through reducer drive shaft and turntable rotation dial edge of the roll pin driven by dozens of roll grinding in the grinding ring raceway within the scroll.
The bulk material by the hammer crusher broken into small particles by the elevator into the storage silos, and then through the vibration feeder and the tilt of the feed tube, the material uniformly to the bulk material of the upper turntable plate.
Material scattered to the circle surrounding the effect of centrifugal force and fall into the grinding ring raceway ring roller impact, rolling rolling, grinding, after the processing of three-ring Road into powder, high pressure air through the pumping action of the external airinhalation machine, and the crushed material with selected powder machine.Coarse material down the rotation of the impeller in the powder re-grinding, discharge shall be finished by the lower part of the discharge valve to meet the requirements of the powder into the cyclone powder collector with air current, and the airflow with a small amount of fine dustdischarged through blower and muffler after the purification of the pulse dust collector.
Calcium carbonate grinding processing:
Dry processing of calcium carbonate products in the same particle size generally wear value than wet processed products, the standard of fineness of calcium carbonate powder morphology, angular, generally higher than the PPC with good fineness. Modern wet milling production technology has been able to control the ultra-fine powder products have similar degrees of wear and PPC.
Grinding of calcium carbonate, after grinding into the mouth of materials with narrow size distribution, with an average particle size of 30-60nm, the utilization of calcium carbonate to a substantial increase of the milling equipment has a compact, no movingcomponents, stable operation, low power consumption and many other advantages.
As a professional mining machine manufacturer, C&M Mining Machinery can provide you with the whole unit of calcium carbonate grinding machines to produce calcium carbonate powder from coarse powder to fineness powder. Before grinding, it is necessary to crush the calcium carbonate materials into pieces whose particle size smaller than 3 inch, the final grain size of calcium carbonate powder can be down to from 600 micron till 5 micron in diameter according to powders’usage. The calcium carbonate material is produced in an ultrafine dry grinding mill in closed circuit with a high efficiency air classifier.
