Application of Rotary Drum Drying Machine for Fertilizers

Applications of Dryer for Fertilizer Production

خط إنتاج الأسمدة

It is suitable for organic و compound fertilizer production line, such as animal manure waste, poultry manure, sheep dung, pig manure, chicken manure, cow manure and sludge.

Feed & Agriculture

It is suitable for make feed, agriculture production and biomass pellet materials like straw, وجبة السمك, leaves, food factory waste, wood chips, shavings and corn residue.

Building Materials

It is appropriate for drying construction materials, specifically for sand, cement, ore, slag, coal, metal powder, clay, و kaolin, إلخ.

Other Industries

It is applicable to the drying of powder and granular materials used in the production of phosphate fertilizer, mining industry, as well as metallurgy, chemical and other industries.

Part & Accessories of A Rotary Drum Drying Machine

The rotary dryer is mainly composed of the following components: أ cylinder, front and rear roller rings, wheel, small gear, feeding and discharge mechanism, lifting plates, reduction drive, motor, hot air duct, air blast furnace, and other parts. فضلاً عن ذلك, we can produce gas burner, combustion chamber, أو elevator, belt conveyor, constant weight feeder, جامع الغبار, induced draft fan, and other devices based on the needs of the customers.

Mechanism of A Rotary Drum Drying Machine?

The rotating cylinder body is flange connected or directly welded, supported by two riding wheels as the supporting device and driven by the drive gear to rotate the simplified body.

The cylinder body is installed with angle, and the materials come into contact with hot flue gas while turning inside the revolving cylinder body and moving ahead to achieve the drying goal.

The machine has feeding and discharging mechanisms. There is a sealing plate between them so that reduces the spillage of materials.

The inducer introduces hot air from the hot blast furnace into the inside of the dryer to exchange heat with the wet materials.

The materials are supplied by the elevator from the feeding port and flow within the dryer under gravity after being broken up, crushed, dispersed, and equally distributed, assuring the heat exchange effect of the materials inside the dryer.

Hot gas is generated by the hot blast furnace, moving from the bottom to the top, contacting with the materials, transferring the heat to the materials through heat conduction, convection, radiation and other ways. هكذا, it continuously makes the temperature of materials rise and the moisture evaporated. Then the materials meeting the moisture requirements are discharged from the lower outlet, and also the gas containing water vapor.

The Main Work Procedure of Rotary Drum Drying Machine

The raw materials enter the inside of the drying rotary drum after passing through the loading machine. After the process of high temperature, deodorization, dust removal and cooling, the materials are dried to less than 10% moisture content at one time.

The materials in the rotary drum cylinder are dried by the spiral blade and intermittent lifting plate in the process of repeated action and lifting between the inner and outer cylinders.

According to the ultimate moisture requirement of materials after drying in different industries, the moisture content of compound fertilizer after drying is lowered from 20%-30% ل 2%-5%, and organic fertilizer is reduced 10% ل 40%.

الأهم من ذلك, the rotary dryer should be used with the cooling machine, because the high temperature of the dried fertilizer is not conducive to storage. بالإضافة إلى, it can also be modified specifications according to the customers’ own requirements to ensure the maximum utilization rate of the dried fertilizer.

Features of Rotary Drum Drying Machine

A variety of lifting plate combination distribution, creates no wind hole phenomenon, and makes materials evenly distributed and fully exchange heat with hot air, with good drying effect. There are vertical baffle plates inside the cylinder to prevent materials from sticking and improve its fluidity.

The cylinder body adopts combined structure and weldment, which improves the precision of equipment, and makes it easier to transport and install. The dryer is equipped with an inlet and outlet device as well as a specific sealing device, which can greatly enhance overall machine performance and increase production capacity.

It is equipped with hot blast furnace, and has features of rapid combustion, sufficient heat supply, high thermal efficiency, as well as excellent drying time regulation. في أثناء, vertical baffle plates expand the contact area between materials’ heat and cold air exchange, ensuring sufficient heat exchange with low energy consumption and high efficiency.

It integrates the complete system of heating, تجفيف, and dust collection, realizing mechanization and automation of operation, and meeting the requirements of environmental protection.

Rotary drum dryer can be widely used in organic fertilizer, الأسمدة المركبة, biomass pellet, feed, agriculture, building materials, المعادن, mining and chemical industry such as drying organic waste, clay, slag, iron powder, fly ash, إلخ.

According to slope of a rotary drying recommendations and the distribution of the lifting plate, it help enhance heating efficiency, and is easy to run, occupies a small area, and is convenient to regulate and control.
