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, vibrating feeder, micro-grinding main 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 size (about 1 cm) suitable for the operation of the ultra-fine mill, and then the fineness of the analyzer is adjusted by adjusting the rotation speed of the analyzer to be suitable for the production requirements. 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 too 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.
5, do not 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 at the same time check whether the gas supply pressure meets the requirements, the timing belt 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.
