Calcium carbonate ultra-fine vertical grinding mill advantages and working principle
Calcium carbonate ultra-fine vertical grinding mill is mainly used for the production of micro calcium carbonate powder with a fineness range of 400-2500mesh. Micro Calcium carbonate powder can be widely used in cables, papermaking, toothpaste, cosmetics, glass, medicine, paint, ink and many other fields, and has higher market application value. The ultra-fine vertical grinding mill integrates crushing, drying, grinding and conveying. It focuses on the large-scale production of non-metallic ore ultra-fine powder. Ultra-fine vertical grinding mill has higher grinding and powder selection efficiency, convenient maintenance, lower operating cost and reliability, High quality, stable product quality, excellent finished product quality, low comprehensive investment cost and other notable features.
The ultra-fine vertical grinding mill is based on the principle of high-efficiency and energy-saving material layer grinding, which has higher grinding efficiency and lower energy consumption;
Calcium carbonate ultra-fine vertical grinding mill is easy to maintain and has lower: operating cost (1) The grinding roller can be turned out of the machine by hydraulic device, the replacement of the roller sleeve and lining plate is easy, and the maintenance space of the mill is large, and the maintenance operation is very convenient; (2) The grinding roller sleeve can prolong the service life of wear-resistant materials;
Calcium carbonate ultra-fine vertical grinding mill has stronger applicability and lower investment. Calcium carbonate ultra-fine vertical grinding mill adopts secondary classification and can produce 325 mesh-2500 mesh powder, realizing multi-purpose of one machine, strong equipment practicability and saving investment cost.
The calcium carbonate powder quality produced by ultrafine vertical grinding mill is stable (1) The raw material stays in the mill for a short time, and it is easy to detect the particle size distribution and composition of the power, and the powder quality is stable; (2) The powder particle shape is uniform, the particle size distribution is narrow, and the fluidity performance is good and strong adaptability in different industries;
Calcium carbonate ultra-fine vertical grinding mill is environment-friendly (1) The whole system of ultra-fine vertical mill has lower vibration and lower noise; (2) The system is sealed as a whole, runs under full negative pressure, and has no dust out, which can basically achieve a dust-free workshop;
The calcium carbonate ultra-fine vertical grinding mill has a higher degree of automation: the automatic control technology adopts the German Siemens series PLC, equipped with an automatic control system, which can realize remote control and easy operation. The workshop can basically realize unmanned operation and save operating costs.
The working principle of calcium carbonate ultra-fine vertical grinding mill
The ultra-fine vertical grinding mill system consists of a main mill, a feeder, a classifier, a blower, a piping device, a storage hopper, an electric control system, and a pulse-jet collector system.
The ultra-fine vertical grinding mill adopts a standardized modular design and pressure devices. With the increase of vertical mill production capacity, the number of grinding rollers in the vertical grinding mill can be correspondingly increased, and 2 rollers, 3 rollers or 4 rollers can be used. Up to 6 grinding rollers can be used in combination with a minimum of standard modular components, which can meet the requirements of different product fineness and output
The motor drives the reducer to drive the grinding table to rotate in the vertical grinding mill. The material moves around the grinding table under the action of centrifugal force and enters between the grinding roller and the grinding table. Under the grinding roller pressure, the material is crushed by extrusion, grinding and shearing force. The powder is blown by the air flow of the blower to the classifier above the main mill for sieving. If the particle size is too coarse, it will still fall into the main machine for regrinding. If the fineness meets the specification, it will flow into the pulse dust collector with the air. The finished product, the purified air flows through the pipeline on the pulse collector and flows into the blower before being discharged into the atmosphere.
