Double roller granulator introduction:
Double roller granulator is also called Extruder pellet machine, which is a new generation of granulation equipment developed by our company and one of fertilizer granulator equipment. This machine uses room temperature granulation, no need to dry, one-time molding. The structure adopts granulation, forming, and sieving into one body, so that it has the characteristics of beautiful appearance, simple operation, low energy consumption, low investment, quick results, and good economic benefits. Features.
Working principle of Double roller granulator:
The belt pulley is driven by the motor, and the drive belt is transmitted to a pair of two high-pressure roller bodies with sliding mode shells through the reducer to do relative work. The two rollers of the DZJ-Ⅰ type Extruder pellet machine interact with each other by a set of split gears. The two rollers of the DZJ-Ⅱ Double roller granulator are directly driven by the two output shafts on a special reducer to work. The purpose of extrusion. During production, the raw materials enter the hopper, are relatively extruded and formed by the high-pressure roller body, and flow to the crushing and forming studio under the roller body after being demolded. The power of crushing and forming is driven by the chain wheel of the active roller shaft to a pair of crushing rollers for relative movement. After crushing and screening in the working chamber, the finished particles pass through the screen to the discharge trough and flow out of the machine.
Double roller granulator structure:
1. Frame part: all the workpieces of the machine are installed on the frame!
2. The transmission connection parts include motor, pulley, V-belt, reducer, chain, sprocket, coupling.
3. The head part: It consists of a bearing frame, a pair of high-pressure die rollers, and two shafts.
4. Crushing studio: it is composed of a crushing roller bearing frame, a crushing roller, a screen, and so on.
Double roller granulator advantages:
1. The machine can not only be used for granulation in fertilizer, feed, and chemical industries but also has good applicability to rare earth, metallurgy, coal, biological agents, and environmental protection projects.
2. It has the characteristics of a beautiful appearance, simple operation, and low energy consumption. The main parts are made of a new type of metal with anti-corrosion, wear resistance, and impact resistance.
3. The structure of the machine adopts granulation, forming, and screening as a whole, which makes it have the characteristics of beautiful appearance, simple operation, and low energy consumption. The main parts are refined from a new type of metal with the characteristics of anti-corrosion, wear resistance, and impact resistance.
