5 Motor Classifier Ultrafine Grinding Mill For Precise Powder Fineness Control
Structure of 5 Motor Classifier Ultrafine Grinding Mill:
The reducer of the ultrafine grinding mill system makes the grinding table rotate. And raw material is delivered into the grinding house by the belt feeder through the air-block device. As the grinding table rotate, there will be centrifugal force, which will move the raw material towards the edge of grinding table. And the raw material will be ground between rollers and grinding table.
Motor power is transmitted to the ultrafine grinding mill reducer via coupling. The reducer outputs torque, which makes the grinding disc rotate circumferentially. It constitutes an important part of a vertical grinder. Ti is equipped with independent lubrication and cooling stations, and automatic protection system of oil pressure and oil temperature. Please refer to its instructions for its working principle and application method.
With the pressure of the roller, the materials are smashed by extrusion, grinding and shearing. At the same time, the airflow will blow the powder up through the classifier, and the coarser powder will be blocked by the turbine classifier and falls down onto the grinding table to be reground. And the fine powder will be collected in the pulse-jet collector. This step repeats until qualified fine powder is discharged. These constitute the entire grinding process.
The ultrafine grinding mill, with static and dynamic separator, can produce powder with a fineness range of 325mesh(40μm) to 2500 mesh(5μm). This ultrafine grinding mill can be widely used in chemical, metallurgy, non-metallic mining industries for grinding limestone, calcite, marble, calcium carbonate, kaolin, barite, bentonite, pyrophyllite etc. Ultrafine grinding mill is capable of providing high qulity filers and additives used in the papermaking, segments, plastic, rubber, pigment,printing ink, PVC and so on.
Rollers of Ultrafine Grinding Mill:
The ultrafine grinding mill roller device is a pair of self-aligning roller bearings. Its design has included calculations of the life of bearing seats. The bearing seal cavity extends the outside of the shell and has no not with dust-laden gas. Therefore, a simple skeleton seal can guarantee no entrance of dust into roller bearings. Grinding rollers are designed with slope installation and wedge-shaped ring compression; so it is quite convenient to replace roller sleeves.
Ultrafine grinding mill roller device is mainly composed of fuel tank, accumulator and connecting pipes and other components. The pressure device may control the pressure of ultrafine grinding mill roller automatically or manually during operation and can adjust the pressure automatically based on material grind ability and wear conditions of the rollers and disc. By doing so, it can both reduce consumption and extend the service life of roller sleeves and liners. At the same time, the buffer effect provided by the accumulator allows the pressure imposed by the hydraulic cylinder to have great flexibility and automatic adjustability. If large and hard debris encountered, the roller may jump to avoid damage to it caused by excessive load.
Special Features of Ultrafine Grinding Mill:
1. Strong product diversity. Ultrafine grinding mill is equipped with multi-motor air classifier, which can produce a wide range of product sizes. There are 30%~70% in the 2μm range, D97=4~45μm;
2. Lower power consumption with advanced design.
3. Narrow particle size distribution and precise 2μm powder content control.
4. After being improved, rollers, grinding table, diversion systems and internal circulation systems can greatly improve the grinding efficiency and improve output by 15%~30% compared to the same type of domestic products, and can save electricity by 30%~60% compared to ball mills, etc.
5. With leading grinding equipment technology, the improved grinder can be operated at low vibration.
