Double roller granulator

Friends who want to buy a granulator, do you know Double roller granulator?

The double roller granulator is actually the abbreviation of the twin-shaft twin-roller granulator. The twin-roller extrusion granulator is mainly for the granulation of inorganic fertilizers and compound fertilizers. The twin-roller extrusion production line does not need to dry the granulation of inorganic fertilizers. , The cooling process saves a certain cost. The roller extrusion granulation production line has a simple process. In the rapid development of the fertilizer industry, the non-drying production line is affected by the environment and is welcomed by the majority of customers.

How to distinguish between single-shaft and double-shaft Double roller granulator

The single-shaft pair-roller extrusion granulator, the motor drives the belt and pulley, is transmitted to the driving shaft through the reducer, and is synchronized with the driven shaft through the split gear, and works in opposite directions. The picture below can be understood at a glance.
The double-shaft pair-roller extrusion granulator is driven by a motor to drive belts and pulleys, which are transmitted to the two output shafts of the reducer through a reducer, and each output shaft drives two grinding rollers to work in opposite directions through a coupling.

What are the advantages of a Double roller granulator over a single-shaft granulator?

The density of the biaxial extruded material is 1-1.5 times higher than the performance of the uniaxial extruded material, that is to say, the particle strength produced by the biaxial pair-roller extruder is significantly higher than that of the uniaxial extruder, and the output is also increased. It is 0.5 times higher, and the granulation rate of the granules reaches more than 95%, and the granules are approximately round. After being shaped by the roller polishing machine, the roundness of the compound fertilizer granules can be comparable.
The shape and size of the ball socket on the roller skin of the double-shaft pair-roller extrusion granulator can be selected according to the needs of users, and there is a wide range of options. The ball press shapes include pillow-like, semi-circular grain, shape, walnut-like, and oblate spherical And square shape. At present, the oblate shape is adopted.

Double Roller Granulator application

1. This machine adopts a non-drying process to produce, granulate at room temperature, and form once.
2. The structure of this machine adopts granulating, forming, and sieving as a whole, which makes it have the characteristics of beautiful appearance, simple operation, and low energy consumption. The main parts, such as the roller body, are refined from a new type of metal with anti-corrosion, wear resistance, and impact resistance. Among them, the DZG-Ⅱ type machine not only has the above characteristics, but our company has also upgraded the frame part. The bearing frame body is made of anti-corrosion casting as an integral part so that it has the characteristics of good stability and can greatly improve the rolling bearing and the large shaft. Service life. The machine has the advantages of compact structure, good stability, good sealing, low noise, convenient operation, and maintenance, etc. After the new machine went on the market, it won the praise of the majority of users!
3. The raw material has wide adaptability. The machine can not only be used for granulation in fertilizer, feed, and chemical industries, but also has good applicability especially for rare earth, metallurgy, coal, biological preparations, and environmental protection projects. To some extent, it fills up the domestic gap and ranks at the forefront of the country. It is also a promotion project of environmental protection projects!
