Application scope: Ultra fine powder processing of non flammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤ 6, s
Product details
Product Features
The three ring medium speed micro powder mill can finely process materials to a particle size of over 3000 mesh, making it a commonly used equipment in the market for processing ultrafine powders. The three ring medium speed micro powder mill is a processing equipment for fine and ultrafine powders, which applies multiple national new grinding machine technologies. It has the characteristics of novel design, reasonable structure, small footprint, low power consumption, long operating life, low cost of vulnerable parts, and high cost-effectiveness. Its technical performance has reached international standards, and this micro grinding is mainly suitable for various non flammable and explosive brittle materials with medium to low hardness and Mohs hardness below level 6, such as calcite, chalk, calcium carbonate, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, zeolite, diatomaceous earth, barite, gypsum, alum, graphite, fluorite, phosphate ore, potassium ore, pumice, etc. Can be used as a desulfurization mill and powder mill. At present, the particle size of fine powder produced by medium speed micro grinding in the third ring can be adjusted between 325-3000 mesh, and the output can reach 0.5-12 tons per hour.
Performance advantages
-
Efficient and energy-saving
When the fineness of the finished product and the power of the motor are the same, the output is more than twice as high as that of the air flow mill, stirring mill, and ball mill. -
Long service life of vulnerable parts
The grinding roller and grinding ring are forged from special materials, greatly improving their utilization. Generally, it can last for more than one year, and when processing calcium carbonate and calcite, its service life can reach 2-5 years. -
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. -
Environmental protection and cleanliness
Using a pulse dust collector to capture dust and a muffler to reduce noise, it has the characteristics of environmental protection and cleanliness.
Structural composition
Structural composition of medium speed micro grinding with three rings
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.
Precautions for medium speed micro powder grinding in the third ring
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.
4. 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.
Working principle
The three ring medium speed micro powder mill crushes large pieces of material into small particles through a hammer crusher, and then sends them to the storage bin by a hoist. After passing through a vibrating feeder and an inclined feed pipe, the material is evenly sent to the upper part of the turntable's bulk tray. The material disperses around the circumference under the action of centrifugal force and falls into the raceway of the grinding ring, where it is impacted, rolled, and ground by the ring rollers. After being processed into powder through three layers of raceway, the high-pressure fan sucks in external air into the machine through suction and brings the crushed material into the powder selection machine. The rotating impeller inside the ultrafine powder mill causes the coarse material to fall back and be re ground. The fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged by the discharge valve at the bottom, which is the finished product. The airflow with a small amount of fine dust passes through the pulse dust collector and is discharged through the fan and muffler.
