Before granulation, it is necessary to use our new type vertical crusher to turn zeolite into powdery. Our new type vertical crusher can crush raw materials efficiently. It will crush large blocks, which is helpful to granulate pellets later.
In the granulating process, we can take disc granulator and double roller granulation machine for two examples.
How does disc granulator turn zeolite into pellets?
The raw material: powder zeolite is mixed evenly by pre-adding water, and then put into the pan. With the rotation of the pan, the materials gradually roll in the pan and form spherical shape pellets. After reaching a predetermined diameter, it is discharged out of the pan and then transported to the next process.
How does double roller granulator turn zeolite into pellets?
Firstly, you can add materials from the feed hopper. And then, double roller press granulator rollers extrude pellets and release them from the mold. They form a pellet through two semi-balls’ combination. Thirdly, pellets fall into the crushing chamber. Under the force of the drive shaft, a chain drives two maces to rotate for separating the extruded but cohesive particles.
Because disc granulation machine adopts wet granulation. The formed pellets’ moisture is about 45%. It will be difficult for storage and transport the formed pellets for sale. Therefore, it is necessary to use our drum drying and cooling machines to control the moisture under the package standard.
However, if granulating machine adopts dry granulation method, like double roller granulator, it will omit the procedures pf drying and cooling. Because the moisture is low for package standard. There is no need to dry, or cool the formed pellets.
After granulation, it is also important to use drum screening machine to screen the unqualified pellets. They may unqualified in pellets’ size, or in density etc., out screening machine can screen them and then, convey them to the production procedures before to granulate again.
Now it’s time to package the qualified pellets for commercial. We have single or double bucket automatic packing machine for choosing. Besides, we also have automatic palletizer to help you convey the bags of zeolite pellets.
