Industrial biomass/coal rotary dryer
Applicable: biomass briquette or coal briquette plant with large production capacity Raw materials: various of powder materials such as: sawdust, coal, coke, mineral powder...Moisture input: biomass materials:less than 35%Coal/coke /mineral powder: 25%;Moisture output: biomass materials: 10-15%Coal/coke: less than 10%
1.Brief IntroductionRotary Dryer has a very wide range of functions, such as dung, wood, sand, slag, etc. According to the structure, it can be divided into: single cylinder type and three-cylinder type. It is mainly used in mineral processing, building material, metallurgy, and chemical industry, etc to dry material with a certain humidity or granularity. Rotary dryer adapts to various materials, whose operation is simple and reliable, and it is widely used. Rotary dryer is mainly composed of barrel, front and rear rollers, input & output parts, transmission parts, and gear cover.
2, Sawdust Three Layer Rotary Drum DryerFor sawdust, we recommend our three layer rotary drum dryer, the three layer rotary dryer developed by DAYANG is heated by a furnace, and the high temperature heat enters the rotary cylinder and pipe directly. On the connection of rotary cylinder and the furnace, there equipped a feeding hopper to receive the raw materials waiting for drying. The wind power from the fan sucks the raw material and heat into the rotary cylinder, and the rotary screw pieces keep rotate and turn over, force the raw material to discharge moisture under great heat. The already dried raw material will be absorbed into the pipe to be exported; while those haven't been dried will stay in the rotary cylinder and continue to be dried.
The three layer design prolongs the effective drying area without enlarging its size and length, which can efficiently enhance the drying output. Also, because of the layers of heat dissipation, it decreases heat loss and makes the drye......url:http://www.dayang-briquettepress.com |
