Technical characteristics

Twisting granulator is a molding machine that can make materials into specific shapes. Turning granulator is one of the key equipments in the compound fertilizer industry. It is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of agglomerates. Through water or steam, the basic fertilizer is fully chemically reacted in the cylinder after adjusting the humidity. ball.

Steam, gaseous ammonia or add phosphoric acid or nitrogen solution, phosphorus ammonia slurry, heavy calcium slurry into the barrel of the granulator to complete the chemical reaction and heating compound fertilizer granulation process in the barrel; or add a small amount of The process of cold granulation of compound fertilizer with moisture. The material to be granulated is passed through the rotation of the cylinder, rolling and rotating when the cylinder is empty, and aggregated into balls under suitable humidity and temperature to complete the ball-making process.

The composition of the stock transfer granulator:

The whole rotating part of the machine body is supported by the bracket, and the force is relatively large. Therefore, the supporting part of the machine is welded by medium carbon steel plate and channel steel, and has passed strict quality control and special process requirements, and has reached this level. the purpose for which the machine is used. In addition to this, the more important thing is to fix it on the shelf. Considering that it will cause great friction with the rolling belt of the body, our factory specially selects high-quality anti-corrosion and wear-resistant materials, which greatly improves the service life of the machine. The supporting wheel frame also adopts the casting integrated technology. In addition, there are swivel hooks at the four corners of the supporting wheel frame, which is convenient for loading, unloading and transportation.
The transmission part of the whole granulator is particularly important. The whole machine works in this way. The transmission frame is welded by channel steel and has passed strict quality requirements. The main motor and reducer installed on the transmission frame All ISO products with reliable performance and quality are selected. The motor drives the pulley, the V-belt and the reducer to drive the main shaft to make the body work. The transmission reducer is in the working part of the main shaft, and the nylon coupling is used to engage and transmit the drive.
It is fixed on the machine body and meshes with the transmission pinion to drive the machine body to work in the opposite direction.
The core of the whole granulator is the body part, which is welded with high-quality medium carbon steel plate and built-in special rubber lining plate or acid-resistant stainless steel lining plate, which realizes automatic scar removal and tumor removal, and cancels the traditional scraper device. And through strict quality control and special process requirements, in order to achieve the purpose of this machine.

The advantages of the drum granulator:

1. Less investment, good economic benefits and reliable performance;
2. Small power, no three wastes discharge, stable operation, convenient maintenance, reasonable process layout, advanced technology and low production cost;
3. High ball strength, good appearance quality, corrosion resistance, wear resistance and low energy consumption;
4. The cylinder body adopts special rubber plate lining or acid-resistant stainless steel lining plate, which realizes automatic scar removal and tumor removal, and cancels the traditional scraper device;

The working principle of the drum granulator:

The belt and pulley are driven by the main motor, and are transmitted to the driving shaft through the reducer. The material is added from the feed end and passes through the inside of the cylinder. It is made into granules by the special structure inside the cylinder, and then flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be achieved.
