Calcite powder machinery
Below is two suitable grinding machinery for calcite powder grinding.
Vertical roller mill is widely used for calcite powder grinding in the quarry market, it can be also widely used in such industries as cement, power, metallurgy, chemical industry, non-metallic mineral. LM roller mill can grind granular and powdered materials into powder with required fineness, and is easy to operate, reasonable structure, reliable performance.
Ball mill is used for pre-processing of various crushable non-flammable and non-explosive brittle materials with Mohs under 9. It is widely applied in the industries of construction, mining, metallurgic, road building and water conversancy etc. By being a component of closed production lines, it can grind calcite powder various size of better effect.
Calcite powder grinder process
1. Raw Material Preparation
In the technics of calcite powder production process, People usually choose calcite powder and clays as the main raw materials, crushing, concocting, grinding them into calcite powder raw material, feeding them into calcite powder kiln. After being calcined maturity, adding appropriate amount of gypsum (sometimes mixing the mixed material or admixture) then being grinded. In the phase, the needed equipment are primary crusher and secondary crusher, such as jaw crusher, cone crusher, impact crusher, mobile crusher, and screens, which both supplied by our company, the calcite powder is reduced to a size less than 100 mm and stored until required.The pre-homogenization process makes the materials storage and homogenization.
2. Raw Grinding-wet process and dry process
In the calcite powder production process, every production of 1 ton of Portland calcite powder grinding at least needs 3 tons of materials (including raw materials, fuel, clinker, mixed materials, gypsum). According to statistics, the grinding process in thedry-process calcite powder production lines operating cost 60% power, in which grinding raw materials accounted for more than 30%, grinding coal accounted for about 3%, and about 40% of calcite powder grinding. Therefore, a reasonable choice of grinding equipment and processes and to optimize the process parameters, the correct operation, the control of operating system, is of is of great significance to ensure product quality and reduce energy consumption.
3. Pyroprocessing
Preheating the raw material and some decomposition are completed by the preheater, instead of some functions of rotary kiln to shorten the length back to the kiln.
Raw material completes the preheating and pre-decomposition in the cyclone preheater. The next process is carried out the rotary kiln and calcined to calcite powder clinkers.
4. Finish Grinding and Distribution
Calcite powder grinding is the final process in calcite powder manufacturing, which cost the most electric power. Its main function is to grind calcite powder clinkers into condign sizes (in fineness, specific surface area etc.) and make them form a certain particle size levels to meet the coagulation, hardening requirements. High Pressure Suspension grinder millis the main equipment in calcite powder grinding. YGM series High Pressure Suspension grinder mill are with high grinding efficiency and with good operation stability.To some extent, they reduce the power consumption or increase the system output. Also in the process technics, compared with the closed-circuit grinding, opened-circuit grinding process is only more saving invest, and more facilitated in the maintenance and management. However, the adjustment of closed-circuit grinding is much more convenient and more adaptable to the quality changes and moisture of raw materials. Some experts on recommending opened-circuit grinding believe that the particle size distributions in the open-circuit calcite powder grinding process are wider, thus the consistency standards demand less water. So the opened-circuit grinding is welcomed in calcite powder mixing station. To choose which one, the calcite powder factory should be based on the actual situation of their choice. But YGM series High Pressure Suspension grinder mill apply to both.
