High humidity materials forming experts Zhengzhou Dingli company according to the market demand, company targeted development of material pellet fuel production line equipment, this production line applicable to the wood chips, sawdust, bamboo shavings, wood shavings, barley straw, oat straw, wheat straw, rye, straw, rice straw, sorghum straw, corn stalks, stem drying potato vines, beans, peanut vine and other material of moisture content is 35-65%.
According to the material of characteristic, production capacity, applying requirement, cost control, operating convenience of each biomass materials, our company optimizes the drying technology. Recommended products: three-layer rotary drum dryer, patent number: ZL2009 2 0089749.2. This equipment is a large processing line. This dryer has high efficiency, energy saving, and small floor space. Compared with other dryer machines, it saves energy by 30%-50%, thus maximum saving energy and drying cost.
The crushed materials of which the moisture is about 35%-65% are sent into the roller by conveyor to realize downstream drying. Under the effect of the inner shoveling plate, materials are taken and scattered constantly, and move in the spiral forward method. Through three layers (inner, middle and outer layer), heat exchange is realized between material and hot air medium.
Automatic control, to ensure the drying of raw material water even and stable. Automatic stone removing and iron removal can ensure that the impurities of the raw material are not in the rear process. The required investment of equipment is 1/6 of imported products.
The design of multiple circumferential flight combinations and flow rate adjustment devices ensure the control of drying period and temperature distribution.
Cylinder self insulation, the thermal efficiency of more than 70%, With tail drive, the transmission is more stable and reliable; completely change the wheel rotation, often slip shadow, Sound production phenomenon.
Compared with the single cylinder drier, the utility model reduces the occupation cost by about 50%, reduces the civil investment by about 50%.
