Roller Granulator with Different Structure

Due to the advantages of high pelletizing rate, good pelletizing effect and high efficiency, the roller pelletizer is widely used in the clay ceramic industry.

Due to the different granulation raw materials and regions, the form of the counter-roll granulator is also different. According to the structural form, it is generally divided into two types: chain drive type and belt drive type, each of which has advantages and disadvantages. Among them, the chain drive is that the output shaft of the motor and the input shaft of the reducer are connected through a coupling, and the output shaft of the reducer is driven by a transmission chain to drive the fixed roller and the movable roller of the granulator synchronously. The synchronously rotating granulation roller can avoid slipping. The ball forming efficiency is higher, but the structure of this type of granulator is more complicated, the noise of the chain transmission is relatively large, and the maintenance and replacement of the chain is more troublesome. The belt drive is a motor that drives the reducer through the belt. The output shaft of the reducer drives the fixed roller of the granulator through a coupling. The fixed roller of the granulator drives the movable roller through friction. This type of granulator has a simple structure. The transmission noise is low and the maintenance is convenient, and if the speed of the granulation roller is not suitable, the speed can be adjusted by replacing the pulley.

There are also two types of holes in the rollers of the roller granulator. In general, both the fixed roller and the movable roller need to be drilled, so that the ball formation efficiency is higher, but the granulation density is poor, and it is suitable for higher moisture. Material with low viscosity. However, when the moisture of some materials is low and the hardness is relatively large, a granulator with a smooth roller and a perforated roller should be used. The granules produced by this type of granulator have good compactness. , High ball formation rate, less broken particles. The Yongchuan project of our company is currently in the late stage of commissioning. Due to the adjustment of the raw material formula, the water content of the material has dropped from 25% to 16%-18%. Poor, more scraps into the kiln. After adjusting the movable roller to smooth roller, the granulation pass rate is greatly improved, the compactness is also very good, and it can meet the quality requirements.
