3 Cylinder Triple Pass Sand Dryer Machine Dust Pollution Electric Driven Type

 
 3 Cylinder Silica Sand Powder Rotary Cylinder Tumble Dryer Product For Different Fuel
 
Description of Sand dryer machine:
Three cylinder triple pass Rotary Drum Dryer Silica Sand First Choice with low price! used for drying certain humidity range granular materials, such as
 
1. casting sand which used in dry-mixed mortar and foundry industry
2. small granular clay used in construction and cement industry
3. small granular material in chemical industry which no chemical change, not afraid of heat and dust pollution
 
such as coal, blue carbon, fly ash, sand, water slag, river sand, quartz sand, slag, clay etc.
 
Working Principle:
The sand dryer gets through the bunker to feeding machine, then the slag is sent to the hot blast stove by a belt conveyor, and through the quicksand pipe into the inner cylinder of the dryer. The slag is pushed forward by raising plate from inner cylinder to the middle cylinder to the outside cylinder. This process of "two in, one out" is completed in the dryer, which can form a heat preservation system.
 
In order to reduce air pollution, we are equipped with a cyclone dust collector and water dust removal. At the same time, the dry slag enter the vibrating screen for screening,and then send finished product slag to the finished product warehouse by a belt conveyor.
 
Application:
Raw material with 10-25% moisture content is suitable for this dryer,and not sticky for the drum or lifting blade. The temperature of air flow is less than 70 degree. When there is any special requirement for high temperature drying, the front part of inner drum and lifting blade could be replaced by heatproof steel plate. The product moisture content is adjustable according different requests, even below 1-0.5%.
 
Technical Parameters of widely used rotary sand dryer:

 
Advantages:
1. The dryer drum made of wear resistant manganese plate, service life 3-4 times than common steel plate
2. Original moisture contain <15%, after drying final moisture contain 0.5-1%.
First choice for cement slag powder, pre-mixed mortar projects.
3. The thermal efficiency is more than 40% higher than that of traditional single drum dryer
4. Fuel applicable white coal, bituminous coal, coal gangue, oil, steam.
5. reduce 60% working place, 60% civil work compare with normal single drum dryer. Easy operation.
6. No air leakage phenomenon, solved the sealing problem.
7. discharge temperature <60 ℃,could storage directly in the silo, no need cooling section.
8. Outer barrel temperature <60 ℃, exhaust gas temperature < 120 ℃, dust collector serve 2 times longer.
9. Save 2/3 coal, 40% electirc consumption. Need <9kg coal to dry one ton raw material
