1、 Product Introduction of Calcite Grinding Machine

The calcite mill is mainly suitable for processing ultrafine powder of non flammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤ 6, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, zeolite, barite, gypsum, alum, graphite, fluorite, phosphate rock, potassium ore, pumice and more than 100 other materials. The particle size of the fine powder product can be adjusted freely between 325-3000 mesh, and the output can reach 0.4-4.5 tons per hour.

The powder mill production line usually consists of a hammer crusher, bucket elevator, storage bin, vibrating feeder, micro powder mill host, variable frequency classifier, dual cyclone powder collector, pulse dust removal system, high-pressure fan, air compressor, electrical control system, etc. Large pieces of material are crushed by a hammer crusher into a feed particle size suitable for ultrafine grinding machines (about 1cm), and then the fineness required for production is achieved by adjusting the speed of the grinding machine analyzer. After manual packaging into bags, automatic micro powder packaging machines can also be configured and different models of grinding machines can be selected according to needs.

2、 Structure and Working Environment of Calcite Grinding Machine

The structural composition of a calcite mill
The main body of the calcite grinding machine consists of a host, a reducer, an analyzer, a fan, a bypass powder collector, a maintenance platform, and an electrical control cabinet. The auxiliary part consists of a jaw crusher, a bucket elevator, an electromagnetic vibration feeder, a storage bin, etc.

What precautions should be taken when operating a calcite mill
1. Regularly check the bearing temperature. If the temperature is too high, check whether the lubrication and transmission parts are normal, and whether the rolling distance is too tight. Promptly identify the cause, take corresponding measures, and in severe cases, stop the machine for inspection.
2. Regularly check the tightness of the drive belt. If the belt is too loose, it will reduce the transmission efficiency and affect the grinding effect. If it is too tight, it can easily cause bearing heating, increase power consumption, and reduce the service life of the drive belt.
3. All transmission components must be securely fastened, and special tools should be used for disassembly or installation. It is prohibited to directly strike with tools such as hammers.
5. Don't forget to check the pneumatic components. After the plastic grinding machine is turned on, it is necessary to regularly check whether there are any air leaks or damages in the pneumatic components, pneumatic circuits, and connections. At the same time, the air supply pressure should be checked to ensure that it meets the requirements. The use of synchronous belts should also be checked regularly. If any problems such as tightness, looseness, jumping, deviation, or severe wear are found, they should be adjusted, repaired, or replaced in a timely manner. The oil storage level of the oil mist device in the gas source triad should be checked regularly, and 20 # spindle oil must be added to avoid blockage of the small holes in the pipeline.

3、 Performance characteristics of calcite mill

1. Efficient and energy-saving: With the same fineness of finished products and motor power, the output is more than twice that of air flow mills, stirring mills, and ball mills.

2. Long service life of vulnerable parts: The grinding roller and grinding ring are forged from special materials, greatly improving their utilization. Under the same fineness of materials and finished products, the service life of worn parts is 2-5 times longer than that of impact crushers and turbine crushers, generally reaching more than one year. When processing calcium carbonate and calcite, the service life can reach 2-5 years.

3. High safety and reliability: Due to the absence of rolling bearings and screws in the grinding chamber, there is no problem of bearings and their seals being easily damaged, and there is no problem of screws becoming loose and damaging the machine.

4. High product fineness: The fineness of the three ring medium speed ultrafine powder grinding product can reach D97 ≤ 5 μ m in one go.

5. Environmental protection and cleanliness: pulse dust collector is used to capture dust, and muffler is used to reduce noise, which has the characteristics of environmental protection and cleanliness.
