The drum granulator is a molding machine that can make materials into specific shapes. Drum granulator is one of the key equipments in the compound fertilizer industry. It is suitable for large-scale production of cold and hot granulation and high, medium and low concentration compound fertilizer. The main working mode is wet granulation. After a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder, and under certain liquid conditions, the rotation of the cylinder is used to make the material particles produce a crushing force to agglomerate into a ball. What is the structure of the drum granulator? Why is the drum granulator able to get the job done and what is its working principle? Here's a simple introduction for you:


First, the drum granulator structure
1, the bracket part
The rotating part of the whole body is supported by the bracket and has a large force. Therefore, the parts of the wheel bracket of the machine are welded by medium carbon steel plate and channel steel, and have passed strict quality control and special process requirements to reach the purpose of the machine use. In addition, more importantly, the support roller fixed on the shelf, because of the large friction caused by the roller belt, the factory deliberately chooses high-quality anti-corrosion and wear-resistant materials, which greatly improves the service life of the machine. The frame also adopts the casting integrated technology. In addition, there are lifting hooks at the four corners of the supporting wheel frame, which is convenient for loading and unloading.
2, the transmission part
The whole granulator transmission part is the most important part of the work of the whole body. The transmission frame is welded with high quality channel steel and has passed strict quality requirements. The main motor is mounted on the transmission frame. The reducer is selected from ISO national inspection-free products, and the quality is reliable. The motor drives the pulley, the V-belt and the reducer to drive the main shaft to make the machine work. The transmission reducer is used in the working part of the main shaft, and the nylon decoupling coupling is used to transmit and drive.
3, big gear
It is fixed on the machine body, and is meshed with the transmission pinion. It works with the moving body of the drive body. It uses high-tech wear-resistant materials to make the machine last longer.
4, the belt
It is fixed to both sides of the body to support the entire body.
5, the body part
The most important part of the whole granulator is the body part, which is welded with high-quality medium carbon steel plate, built-in special rubber lining or acid-resistant stainless steel lining, which realizes automatic scars and tumor removal, and eliminates the traditional scraper device. Through strict quality control and special process requirements, the purpose of the machine is achieved.

Second, the principle of drum granulator
The working principle of the drum granulator is that the main motor drives the belt and the pulley, and the drive shaft is driven to the drive shaft through the reducer, and the split gear mounted on the drive shaft is meshed with the large gear ring fixed on the body, facing each other to work. The material is added from the feed end through the inside of the cylinder. Through the special structure inside the cylinder, it is made into granules and finally 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.

Its main features are as follows:
1. Low investment, good economic returns and reliable performance;
2. Low power, no three waste 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, low energy consumption;
