Calcite mill Introduction

First, the calcite mill product introduction

Calcite mill is mainly suitable for ultra-fine powder processing of non-inflammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤6, such as calcite, chalk, limestone, dolomite, carbon black, kaolin and bentonite. , talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, barite, gypsum, alum, graphite, fluorite, phosphate rock More than 100 kinds of materials such as potassium ore and pumice, the fine powder finished product can be adjusted arbitrarily between 325-3000 mesh, and the output can reach 0.4-4.5 tons per hour.

Mill production line usually has hammer crusher, bucket elevator, storage bin, vibration feeder, micro-grinding machine, frequency classifier, double cyclone dust collector, pulse dust removal system, high pressure fan, air compressor , electrical control system and other components. The bulk material is crushed by a hammer crusher into a feed particle size (about 1 cm) suitable for the operation of the ultra-fine mill. Then, by adjusting the rotation speed of the mill analyzer, the fineness suitable for the production requirements is achieved, and the bag is manually packaged. It is also possible to configure automatic micro-powder balers and different types of mills as needed.

Second, the structure and working environment of calcite mill

Structural composition of calcite mill

The main part of the calcite mill consists of a main machine, a reducer, an analysis machine, a fan, a bypass dust collector, a maintenance platform and an electric control cabinet. The auxiliary machine part is composed of a jaw crusher, a bucket elevator, an electromagnetic vibrating feeder, a storage bin and the like.

What should you pay attention to when working with calcite mill?

  • 1. Check the bearing temperature frequently. If the temperature is too high, check whether the lubrication and transmission parts are normal, and whether the rolling distance is too tight. Identify the cause in time and take corresponding measures. If the situation is serious, stop the inspection.
  • 2. Always check the tightness of the belt. If the belt is loose, it will reduce the transmission efficiency and affect the grinding effect. If it is too tight, it will easily cause bearing heat, increase power consumption and reduce the service life of the belt.
  • 3. All kinds of transmission components must be fastened and reliable. Special tools should be used for disassembly or installation. It is forbidden to directly hit with tools such as hammers.
  • 4. Don't forget to check the pneumatic components. After the plastic mill is turned on, always check the pneumatic components in the gas path, whether there is air leakage or damage in the gas path and connection, and check whether the gas supply pressure meets the requirements. The use of the situation should also be checked frequently. If it is found to be too tight, too loose, beating, deviation, and serious wear, it should be adjusted, repaired or replaced in time. The oil quantity of the oil mister in the gas source triplet should be checked regularly, and 20# spindle oil must be added to avoid blockage of the small holes in the pipeline.

Third, the performance characteristics of calcite mill

  • 1. High efficiency and energy saving: When the fineness of the finished product and the motor power are the same, the output of the jet mill, the agitating mill and the ball mill is more than double.
  • 2. The service life of the wearing parts is long: the grinding rolls and grinding rings are forged by special materials, so that the utilization degree is greatly improved. In the case of the same material and finished product fineness, the wear life of the impact crusher and the turbo crusher is 2-5 times longer, generally more than one year. When processing calcium carbonate and calcite, the service life can reach 2 -5 years.
  • 3, high safety and reliability: Because there is no rolling bearing and no screw in the grinding cavity, there is no problem that the bearing and its sealing parts are vulnerable, and there is no problem that the screw is easy to loose and destroy the machine.
  • 4, the product fineness: three-ring medium-speed ultra-fine grinding products fineness can reach D97 ≤ 5μm.
  • 5, environmental protection, cleaning: the use of pulse dust collector to capture dust, the use of muffler to reduce noise, environmentally friendly, clean features.
