Drum Granulator Technological Design Details
Roller granulator is a kind of molding machine which can make material into specific shape. Drum granulator is one of the key equipments in compound fertilizer industry. It is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizer. The main working mode is wet granulation.
After a certain amount of water or steam is injected into the base fertilizer, sufficient chemical reaction takes place in the cylinder. Under certain liquid conditions, the rotation of the cylinder makes the material particles produce crushing force and agglomerate into a ball. What is the structure of drum granulator?
Why is drum granulator competent and what is its working principle? Here is a brief introduction:
1、 Structure of drum granulator
1. Bracket part
The rotating part of the whole body is supported by a bracket, which has a large force. Therefore, the locomotive wheel bracket parts are welded with medium carbon steel plate and channel steel, and through strict quality control and special process requirements, in order to achieve the purpose of machine use. In addition, more important is the idler fixed on the shelf. Due to the high friction of the idler belt, the factory specially selected high-quality anti-corrosion and wear-resistant materials, which greatly improved the service life of the machine. The frame also adopts the casting integration technology. In addition, hooks are arranged at the four corners of the supporting wheel frame to facilitate loading and unloading.
2. Transmission part
The transmission part of the whole granulator is the most important part of the whole body. The transmission frame is welded with high quality channel steel and has passed the strict quality requirements. The main motor is mounted on the drive frame. The reducer adopts ISO national inspection free products with reliable quality. The motor drives the belt pulley, V-belt and reducer to drive the main shaft to make the machine work. The main shaft work part uses the transmission reducer, the transmission and the drive uses the nylon decoupling coupling.
3. Big gear
It is fixed on the body and meshed with the transmission pinion. It works with the moving body of the driving body. It uses high-tech wear-resistant materials, so that the service life of the machine is longer.
4. Belt
It is fixed to the sides of the body to support the whole body.
5. Body parts
The most important part of the whole granulator is the body, which is welded by high-quality medium carbon steel plate, with special rubber lining or acid resistant stainless steel lining built in, which realizes the automatic scar and tumor removal and eliminates the traditional scraper device. Through strict quality control and special process requirements, to achieve the purpose of the machine.
2、 Principle of drum granulator
The working principle of the drum granulator is that the main motor drives the belt and pulley, the transmission shaft is driven to the transmission shaft through the reducer, and the split gear installed on the transmission shaft is meshed with the fixed big gear ring. Put it on your body and work face to face. The material is added from the feeding end through the cylinder. Through the special structure of the cylinder, the particles are made and finally flow out through the discharge port. Due to the continuous entry of materials and continuous rotation of granulator, batch production can be realized.
Its main features are as follows
1. Low investment, good economic benefit and reliable performance;
2. Small power, no three wastes discharge, stable operation, convenient maintenance, reasonable process layout, advanced process and low production cost;
3. The steel ball has high strength, good appearance quality, corrosion resistance, wear resistance and low energy consumption.
