How to Make the Surface of Granules with Protective Film?

The fertilizer drum coating machine is composed of a stirring tank, an air compressor, a host, a conveyor and so on. The machine adopts a special liquid raw material or a spraying process combined with solid powder, which can form a protective film on the surface of the compound fertilizer particles to isolate it from the outside air. Consequently, effectively preventing the salt bridge effect and moisture absorption on the surface of the fertilizer. At the same time, the surface brightness of the particles is improved, and some trace elements can be appropriately added to improve the fertilizer efficiency. And it can prolong the effect of fertilizer in the soil, and can effectively improve the use effect of compound fertilizer.

When the finished granules flow uniformly into the coating machine and then continue to roll, first use compressed air and a special nozzle to spray the prepared oily mixed coating agent into a mist and apply it on the surface of the compound fertilizer particles. The surface of the compound fertilizer particles is coated with a uniform protective film, which effectively prevents salting out and moisture absorption on the surface of the fertilizer. This equipment is specially designed on the internal structure according to the coating process requirements, and it is an effective special equipment for preventing agglomeration of compound fertilizers.

Drum coating machine is available for fertilizer production plants.

What are the Component of the Drum Coating Machine?

  1. Bracket part: The whole rotating part of the machine body is supported by the bracket, which bears greater force. Therefore, the supporting wheel frame of this machine is welded with medium carbon steel plate and channel steel, and has passed strict quality control and special process requirements, which has achieved the purpose of this machine. In addition, the more important thing is the supporting roller fixed on the shelf. Considering that it will have greater friction with the machine body rolling belt, our factory deliberately selects anti-corrosion and wear-resistant materials, which greatly improves the service life of the machine. Casting integrated technology is also used. In addition, there are hoisting hooks at the four corners of the supporting roller frame, which is convenient for loading, unloading and transportation.
  2. Transmission part: The transmission part of the whole coating equipment is particularly important, and the work of the whole body is carried out by this. The transmission frame is welded by channel steel and has passed strict quality requirements. The main motor and reducer installed on the transmission frame are all selected products with reliable quality. The motor drives the belt pulley, the V-belt, and the reducer to the main shaft to make the machine body work. The transmission reducer and the main shaft work part are driven by nylon pin couplings.
  3. Big gear ring: This part fixed on the machine body, toothed with the transmission pinion gear, opposite to drive the machine body to work, it uses high-tech wear-resistant materials, so that the machine has a longer service life.
  4. Rolling belt: Fixed on both sides of the machine body to support the whole coating equipment body.
  5. Body part: The important part of the whole coating machine is the body part, which is welded by medium carbon steel plate, and has passed strict quality control and specific process requirements to achieve the purpose of the machine.

How to Deal with the Moisture Content of Granules after Granulation?

Rotary dryer is a large-scale machine used to dry shaped fertilizer granules, which is one of the essential equipment in the fertilizer industry. The rotary drum drying machine uses a fan installed in the rear of the machine to continuously draw the hot heat in hot blast stove at the nose to rear of the machine. With the continuous rotation of the machine body, the internal lifting plate continuously raises the formed particles. Throw it down, making the material fully contact with the hot air to take away the moisture in it, so as to achieve the purpose of uniform drying. The rotary drum drying has the advantages of reasonable structure, excellent production, high output, low energy consumption and convenient operation. The quality of our products is guaranteed, and the reputation is supreme for free installation and commissioning.

Where can You the Rotary Dryer be Used?

Rotary dryers are widely used in building materials, metallurgy, chemical and cement industries to dry slag limestone, coal powder, slag, clay and other materials. The machine is mainly composed of rotating body, lifting plate, transmission device, supporting device and sealing ring. In the center of the rotary dryer, it is possible to avoid adding a dispersing mechanism. The wet material that enters the drying cylinder is repeatedly picked up and thrown off by the copy plate on the wall of the drum, and is broken into fine particles by the dispersing device during the falling process. ,The specific area is greatly increased, and it is fully contacted and dred with hot air. The drying efficiency is as high as 80%, which is significantly higher than similar domestic equipment.

How to Dry the Moisture Content of Granules?

The inside of the rotary dryer is welded with various copy plates with different angles in a staggered arrangement from the front to the back. According to the type of feed material, a squash ball with a diameter is added to the barrel to prevent highly viscous materials from sticking to the barrel wall. The machine is mainly composed of rotating body, lifting plate, transmission device, supporting device and sealing ring. The dryer is a cylinder that is slightly inclined to the horizontal direction. The material is added from the higher end, and the high-temperature hot flue gas flows into the cylinder concurrently with the material. As the cylinder rotates, the material moves to a lower level due to gravity. One end. A copy board is installed on the inner wall of the cylinder to pick up and sprinkle the material to increase the contact surface between the material and the airflow, so as to increase the drying rate and promote the advancement of the material. The dried product is collected from the lower part of the bottom end.

9 Highlights Designs in the Construction of Rotary Drying Equipment

  1. The rotary dryer has high thermal efficiency and obvious energy saving effect. After testing, the thermal efficiency greatly exceeds the level of the traditional single-cylinder dryer about. After the dryer is put into production, the coal-saving effect is obvious.
  2. The drying mechanism is scientific and fair, and energy-saving. The material exchanges heat with the hot air flow in the inner cylinder in the form of radiation, convection and conduction, and the heat exchange in the outer cylinder is in the form of conduction and convection.
  3. The length of the dryer is shortened, which is conducive to process layout. The length of the whole machine is about 40 shorter than that of the single-tube dryer, thereby reducing the building area of the plant, saving engineering investment, and being more suitable for the process layout of the old factory renovation.
  4. The dryer equipment adopts the downstream drying process of materials and hot air flow, which has a wide range of combined use. It can be adapted to the drying of various raw materials such as clay, coal, slag, iron powder. And also suitable for the drying of various bulk materials in metallurgy and chemical industries.
  5. The rotary dryer has a compact structure. The whole machine is arranged horizontally and adopts supporting wheels to support. The large and small gear transmission is eliminated, and the supporting wheel transmission is replaced, which makes the equipment installation more convenient, the operation simpler, the operation more reliable, and the operation rate higher.
  6. A variety of lifting board designs, the angular lifting board and the 40 lifting board are organically combined to make the material and hot flue gas exchange more fully, reducing the mechanism of “wind tunnel” in the dryer cylinder.
  7. Use frequency conversion speed regulation to adjust the rotation speed of the dryer barrel, and use an appropriate rotation speed according to the moisture content and output requirements to ensure the needs of the next process.
  8. The external surface area of the rotary dryer is more than 30% less than that of the single-cylinder dryer, and the outer cylinder has the effect of heat preservation and heat insulation on the inner cylinder. The surface temperature of the outer cylinder is low, and the heat loss is small. Improved the working environment and working conditions.
