rattler-drying machinery

product presentation
Drum dryer is one of the traditional drying equipment, the equipment is reliable operation, flexible operation, strong adaptability, large processing capacity, widely used in mechanism charcoal metallurgy, building materials, chemical industry, coal washing, chemical fertilizer, ore, sand, clay, kaolin, sugar and other fields, diameter :Φ600-Φ2000mm, length depends on drying requirements. In the center of the drum dryer, the dispersing mechanism can be avoided, and the wet material entering the drying cylinder is repeatedly copied and dropped by the plate on the wall of the rotary cylinder, which is in full contact with the hot air and dry. It is widely used in alfalfa drying, alcohol lees drying, straw drying, wood chips drying, marigold drying, shavings drying, ginkgo leaf drying, Chinese herbal medicine drying, beer lees drying, liquor lees drying, potato starch residue drying, cassava residue drying, malt drying, melon seed drying, sweet bagasse drying, hawthorn drying, rapeseed cake drying, vegetable drying, etc. The thermal efficiency is as high as 80%. The machine is mainly composed of rotary body, lifting plate, transmission device, support device and sealing ring. The dryer is a cylinder slightly inclined to the horizontal direction. The material is added from the higher end, and the high temperature hot smoke and material flow into the cylinder. With the rotation of the cylinder, the material runs to the lower end due to the action of gravity. The inner wall of the cylinder is equipped with a plate to copy and sprinkle the material, so that the contact surface between the material and the air flow increases, so as to increase the drying rate and promote the material forward. The dried product is collected from the bottom of the bottom.
Operating Instructions for Roller Dryers 
After the trial operation of the 1. is normal, turn on the air shutoff machine-entrainer-discharging machine-roller main engine-crushing feed-feeder in the following order.
 When the inlet temperature of the drum reaches 300 oC, a small amount of feed can be started. Pay attention to control the outlet temperature within 60~100 oC, when the discharge is basically up to standard, before normal feeding. When the air outlet temperature is low, the drum speed can be lowered, thus reducing the quantity of discharge or feeding and ensuring the discharge moisture. When the outlet temperature is on the high side, the drum speed can be increased and the discharge or feeding quantity can be increased. In general, only adjust the drum speed, but to control the feed speed, both should be stable and uniform.
 3. normal, hot air inlet temperature control at 800~900 oC, do not blindly increase the temperature for the pursuit of output.
 4. the material after drying, the temperature is high, must spread out cool, reach the normal temperature before bagging.
 Before the 5. stops, the temperature of the hot blast stove is reduced, the coal addition of the gas generator is stopped, and the feeding quantity is reduced accordingly during the cooling process. stop feeding when the hot air inlet temperature drops below 300 oC. Roller main body, feeding, feeding, and other parts continue to operate.
 6. when the discharge port is out of stock, stop the drum, discharge, air closure and draft fan, the above order can not be reversed.
 Highlight advantages
 1. drum dryer production, less fuel consumption, good drying effect.
 2. roller dryer has the characteristics of high temperature resistance and can use high temperature hot air to dry the material quickly.
 3. extensibility is strong, even if the output increases slightly, also does not need to replace the equipment.
 4. equipment adopts the center-adjusting tug structure, the tug and the rolling ring cooperate well, greatly reduces the wear and the power consumption, the specially designed gear structure, greatly reduces the horizontal thrust caused by the equipment tilting work.
  5. has strong anti-overload ability, stable operation and high reliability.
Working principle
 Roller dryer mainly consists of drum body, lifting plate, gear ring, aperture, speed regulating motor and other components. The drum dryer is a cylinder slightly inclined to the horizontal direction. The material is added from the higher end, and the high temperature hot gas flow and the material flow into the cylinder. With the rotation of the cylinder, the material runs to the lower end due to the action of gravity. The inner wall of the cylinder is equipped with a lifting plate, which can make the material rise and fall, increase the contact surface between the material and the airflow, improve the drying rate and promote the material forward. the dried product flows out from the shakron collector.
