coal pulverizer, coal mill pulverizer Introduction:
The ball mill is one kind of new high efficient grinding machine. This mill is mainly used for coarse powder and small size of sand producing. The ball mill is widely used in metallurgy, mining, chemical, cement, construction, industrial and mining industries etc. .
coal pulverizer, coal mill pulverizer features :
Milling efficiency
Mechanically simple design
Competitive capital cost
Use of low cost, ceramic, natural silica sand or pebble media
No steel contamination of product
Capacity to operate continuously at full load power draw
Low rotational impeller speed with shallow charge depth providing reduced abrasion of impeller and body liner coverings
coal pulverizer, coal mill pulverizer benefits:
High production capacity and high crushing ratio.
Low power consumption, uniform particle size.
Simple structure, easy to operate.
Low investment cost, easy management.
To reduce the resistance, no accumulation of materials the use of curved duct and tangential air flow into the sliding reduce the resistance. The export orientation to the dispersion of the material inside is not easy to jam. Compact the design of tapered gear driving the spindle overall transmission and integration structure makes the machine more compact structure, which make installation and adjustment faster and more convenient.
coal pulverizer, coal mill pulverizer application:
The ball mill is key equipment in grinding industry, especially in mineral ore dressing plants. It is widely used for the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc.
coal pulverizer, coal mill pulverizer working principle:
Closed system: The bulk materials are crushed to the desired size by jaw crusher. Then the materials will be sent to the storage hopper by the elevator. After vibrating feeder, materials will be even quantitatively and continuously into the indoor host grinding. After grinding, the powder is away by fan airflow, the powder selecting machine will grade the powder.
Accord with the fineness of fly will be into the large cyclone collector with the gas flow through the pipe to be isolated and collected, and then the powder will be discharged from the powder tube discharge. The airflow returns air duct fan from large cyclone collector inhalation top.
Open system: In the grinding chamber internal grinding material with certain water content, the grinding heat generated in grinding chamber gas vaporizing expansion changes the gas flow rate, and the various machine pipe joint seal is not strict, let the outside gas is inhaled, the circulating air volume increase, therefore to achieve balance through adjustment of air exhaust fan and host the pipe, and the excess gas into the bag filter, the residual gas into the powder collected, the residual gas is discharged after purification.
coal pulverizer, coal mill pulverizer frequently questions :
Q: "What's the technique structure of ball mill machine?
A: Cast steel hollow shaft, lined with removable, rotary gear hobbing by casting process, the body inlaid cylinder liner wear, has good wear resistance. Smooth mill operation of the machine, reliable.
Q: "Can introduce the details of several issues when used ball mill to grind rocks?"
A: 1. Additional ball mill should be regularly in order to maintain the best ball mill loading.
2. Running regularly on the recirculation pump, piping and recycling containers to wash, cyclone should also be regularly switch, flush to prevent clogging.
3.Ball mill output should be in the best run, should not easily change the output.
