1、 Product Introduction of Ultra fine High strength Raymond Mill

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.

2、 Structural composition and working environment of ultrafine high-strength Raymond mill

Structural composition of high-pressure suspension roller mill

The complete configuration of the ultrafine grinding machine includes a hammer crusher, a bucket elevator, a storage bin, a vibrating feeder, a fine grinding host, a variable frequency classifier, a dual cyclone powder collector, a pulse dust removal system, a high-pressure fan, an air compressor, and an electrical control system.

Working environment of ultrafine ore grinding machine

1. Cleaning the equipment: After long-term operation, the grinding machine is prone to dirt that needs to be cleaned. During the cleaning process, high-pressure and high-temperature water guns should not be used to rinse, especially the electrical parts, which should not be washed with water to avoid electrical burnout.

2. Selection and replacement of oil: When selecting fuel oil, attention should be paid to the properties of the fuel oil. The commonly used fuel oil is diesel, but it should be noted that diesel with a freezing point higher than or equal to the ambient temperature should not be used. Generally, diesel with a temperature 5 degrees lower than the ambient temperature should be selected, such as -10 #, -20 #, -35 #, etc. When cleaning, it is also necessary to thoroughly clean the fuel system, and at the same time, check whether the fuel pump is normal to eliminate potential faults. Cleaning the fuel system is also to ensure that fuel oil can be added to keep up with the operation of the equipment during startup. For the replacement of lubricating oil or grease, attention should be paid to the equipment's use of lubricating oil, and whether replacement is necessary should be determined based on the amount used.

3. Maintenance of components: During the operation of the grinding machine, each component has different temperatures according to its work content. There is a cooling system in the equipment. During maintenance, attention should be paid not to allow sediment in the water tank of the cooling system. If it is found, it should be removed in a timely manner, and the water temperature in the water tank should not be too high or too low. Antifreeze should be added to the water tank.

3、 Performance characteristics of ultrafine high-strength Raymond mill

Performance characteristics of high-pressure suspension roller 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 product fineness 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.
