25T/h Sand Dryer Machine

Insulation Structure Triple Drum Rotary Yellow Sand Dryer For Dry Mortar Plant

 
 
Product Descriptions:
 
Three cylinder river sand dryer is also called three drum dryer, or dryer drum or rotary dryer machine, etc. It is a kind of drying equipment widely used in mining system to dry metal and magnetic, floating concentrate, the clay of cement industries and the slime of coal, etc.
 
Working Principles:
 
Material are delivered to the hopper by belt conveyor or bucket elevator . Then they go into the the charger tip by passing through the pipe of charger. When materials go into the tip of the dryer , heat carrier go into the dryer with material.After that ,they go into the discharging exit by passing through inner drum , middle drum and outer drum to go into the discharging storehouse .
After heat carrier pass through the dryer it needs cyclone dust collectors to gather in the material within the gas . If you want to reduce the amount of dust within tail gas , you should use bag duster or wet process duster to discharge .Then, materials are sifted and segregated qualified production by linear vibrating screen.
 
Main Parameters of Sand Dryer:
 

 
Sand Dryer Classifications:
 
1. According to the heat transfer between the drying medium and wet materials, rotary dryer can be divided into direct heat transfer rotary dryer (the direct contact and heat transfer between drying medium and wet materials) and indirect heat transfer rotary dryer (the heat required by the drying process is indirectly passed to the wet materials by the cylinder wall).
2. Indirect heat transfer rotary dryer is rarely used due to its low transmission efficiency and complex structure and it can be divided into single passage rotary dryer and triple passage rotary dryer according to the quantity of the shell drum.
 
Features:
 
1. Unique design more than 20 drying room,which greatly promotes the contact are of the heat and material,make full use of heat,reduce energy losses.
2. Special support wheel channel design,greatly extend the life of support wheel,widened and thickned the roller run,no worries,when the dryer is mould,then to locate the machine,ensure the machine can’t run away.
3. Guide vane is adopted special alloy steel material which is wear-resistant high temperature resistant.
4. The dischanrging temperature is low,can be directly into the storage soil,unnecessary cooling.The fuel can be anthracite, bituminous coal, oil, steam, low consumption.
5. Small occupation area, low construction investment,convenient installation.
