Ground calcium carbonate is ground from natural carbonate minerals (such as calcite, marble, and limestone). It is a commonly used powder filler and is widely used in industries such as papermaking, plastics, rubber, paint, coatings, adhesives, and sealants. . At present, the equipment in the mining industry is constantly updated, and customers who are going to enter the industry see more and more grinding equipment. The grinding equipment of CLIRIK mainly includes Raymond mill, ring roller mill, ball mill, and ultra-fine vertical mill. powder machine etc. So, which equipment is suitable for grinding ground calcium carbonate?
Raymond mill mainly processes 200-400 mesh powder products, and is the mainstream equipment for processing powder products below 325 mesh. Equipped with a classifier, it can process 800 mesh products, but the output is small.
The ring roller mill is mainly used to process 200-2500 mesh products, which has the advantage of low energy consumption, but the production capacity of a single machine is not large.
Ball mill is equipped with a superfine classifier, which can process 600-2500 mesh ultrafine powder at a time. The production capacity of the single machine is large and the performance is stable, but the energy consumption is high.
Vertical mill (with its own classifier, which can be equipped with a secondary classification system) can process ultra-fine powder of 150-3000 mesh, D50=2 micron, D97=4 micron. Production particle size range: below 1250 mesh without secondary classification, 1250-3000 mesh after secondary classification. The vertical mill has the characteristics of large independent capacity, stable operation, high output, stable product quality, and low energy consumption (30%-40% higher energy efficiency than ball milling).
Introduction and advantages of vertical mill
The ultra-fine vertical mill is a new type of mill designed on the basis of the mill, and belongs to the type of mill with a high degree of strengthening of the mill. The ultra-fine vertical mill is wider than the traditional mill, the milling particle size is finer, and the milling efficiency is higher.
The CLUM vertical mill has the following added advantages:
● Multifunctional full hydraulic operating system
● Involute type high-efficiency crushing chamber
● High precision spindle
● High-strength counterattack frame
● Heavy duty rotor
The improved dust removal system is more environmentally friendly, energy-saving and low power consumption than the previous mill. The electrical system of the ultra-fine vertical mill adopts centralized control, and the automation level is better. The vibrating feeder is small in size, light in weight, uniform in feeding, energy-saving, easy to operate, and easy to maintain. The analysis machine adopts an adjustable control system. Reduced power consumption and maintenance costs.
The dust-proof standard of the ultra-fine vertical mill has reached the national standard, and the grinding device also adopts a more advanced stacked multi-stage sealing setting method, which can actually greatly improve the sealing performance of the equipment. With good sealing performance, the ultra-fine vertical mill has a greater advantage in the work of heavy calcium grinding.
