Flat die granulator is a kind of commonly used granulation equipment, mainly used for powder or granular materials for granulation processing, the loose powder materials through the action of pressure and friction into a certain shape and size of the particles. Commonly used in fertilizer production line, feed production line and cat litter production line, etc.
The raw materials used by flat die granulator in fertilizer, feed and cat litter production line are as follows:
Fertilizer production line: urea, diammonium hydrogen phosphate, ammonium sulfate, ammonium nitrate, calcium superphosphate, potassium sulfate, potassium magnesium sulfate, potassium chloride, magnesium sulfate, and so on.
Feed production line: corn, soybean meal, fish meal, bone meal, protein powder, bran, starch, bagasse, wood chips, rice husk, wheat bran and so on.
Cat litter production line: natural bentonite, corn cores, wood chips, bamboo chips, silica gel, quartz sand, paper shavings, rice husk and so on.
Different types of fertilizer, feed and cat litter production line focus on different, the use of raw materials are also different, in the actual production, but also need to choose the appropriate raw materials according to the specific production process and product requirements.

The flat die granulator is mainly composed of feeding system, pressing system, regulating system, transmission system and discharge system.
Among them, the feeding system includes feeder and feed opening;
The pressing system includes mold rollers and pressing chamber;
The regulating system includes a regulating device and a control panel; the transmission system includes a motor, a reducer and a transmission device;
Discharge system includes particle discharge outlet and discharge device.
The working principle of flat die granulator is to press the material into granules by mechanical pressure.
The material is firstly fed into the pressing chamber by the feeder, and then pressed by two parallel die rollers.
During the pressing process, the die rolls rotate and the material is squeezed between the two rolls, after a certain pressure and shear force, the material gradually forms granules.
Finally, the finished pellets are discharged through the outlet.
1) Flat die granulator has the advantages of good granulation effect, uniform granules and regular shape of granules. By adjusting the gap and rotating speed of the mold rollers, the size and shape of the granules can be controlled to meet the needs of different granules.
2) The equipment is simple to operate and easy to maintain. Only simple adjustment and cleaning work is needed to keep the equipment running normally.
3) The flat die granulator has a wide range of application and can handle a variety of materials, such as chemical raw materials, food additives, pharmaceutical intermediates and so on. At the same time, for some difficult to granulate materials, can also be adjusted through the process parameters to achieve efficient granulation.
4) The equipment has a compact structure, small footprint, suitable for use in the laboratory or small production line.
5）Flat die granulator has high granulation efficiency and output, which can meet the demand of mass production.
