Dryer in organic fertilizer production

Dryer in organic fertilizer production

Fertilizer dryer is a widely used organic fertilizer drying equipment, which has the advantages of reasonable structure, high output, low energy consumption, convenient operation and so on. It is widely used in the drying of cement industry, clay, livestock manure sludge, etc. and the drying of organic fertilizer and coal slime in coal mine industry.

1、 Structure of organic fertilizer dryer

The organic fertilizer dryer is generally composed of cylinder, front roll ring, rear roll ring, gear, idler, traction roll, pinion, discharge part, lifting plate, reducer, motor, hot air duct, feed chute, furnace body, etc. The cylinder is driven by gear, and the speed is generally 2-6r / min. the inclination of the cylinder is related to its length, which is generally about 1 ° — 5 °.

2、 Performance advantages of organic fertilizer dryer

The internal structure design of the organic fertilizer dryer is reasonable. In the process of organic fertilizer manufacturing, the contact area between organic fertilizer particles and hot air is large, and the organic fertilizer can be fully dehydrated by heat exchange. Organic fertilizer can be fully mixed and stirred in the square board, which can prolong the blanking time. Time, so as to prolong the contact time with hot air, which is conducive to the residence time of organic fertilizer in the drum and make the organic fertilizer dehydrate more thoroughly.

3、 Working principle of organic fertilizer dryer

The organic fertilizer dryer generates heat through high heat such as electric power, diesel power, wind power, coal and flammable materials. It is heated by the surrounding air and transported to the surrounding area to reach the appropriate temperature for dehumidification treatment. The specific process of the dryer is as follows: wet materials are sent to the hopper by the belt conveyor, and then enter the feed end by the feeder through the feed pipe.

The inclination of the feed pipe is greater than the natural inclination of the material to make the material smooth. Flow into the dryer. The drying cylinder is a rotating drum slightly inclined to the horizontal line. The material is added from the higher side; The heat carrier enters from the lower end and contacts with the material countercurrent, which also connects the heat carrier with the material.

Fluid enters the cylinder. Due to the rotation of the cylinder, the material moves to the lower end under the action of gravity. When the wet material moves forward in the cylinder, it directly or indirectly obtains the heat of the heating medium to dry the wet material, and then it is sent out by the belt conveyor at the discharge end.

In addition to dryers, as one of China’s leading fertilizer manufacturers, our company also produces other types of organic fertilizer manufacturing processes and NPK fertilizer production machines with high quality and low price. Welcome to buy.
