The dry granulation rotary granulator re-granulates dry powder that has been pressed into blocks. A gearbox speed reducer changes speed and direction so the grinding blade and pressing blade rotate in opposite directions; the pressed blocks are broken down and squeezed out of the screen cylinder into granules of the required size. Stainless steel contact parts keep the material free from contamination, and the machine is simple to operate, easy to clean and compact in size.

The speed reducer uses a gearbox to change speed and direction, causing the grinding blade and pressing blade to rotate in opposite directions. During pressing, the material is pressed down by the inclined plane, and the grinding blade squeezes the material out of the screen cylinder, thus forming granules.

• Simple operation, convenient maintenance and easy cleaning: the granulating chamber opens quickly so operators can inspect and wash the machine between batches.
• Stainless steel contact parts: all parts that touch the material are stainless steel, so the product does not deteriorate or change color.
• Selectable screen mesh: the screen cylinder can be chosen according to the required granule size.
• Counter-rotating blades: the grinding blade and pressing blade turn in opposite directions for steady, even granulation.
• Automatic discharge: granules leave the cylinder automatically, reducing manual handling.
• Gearbox speed reducer and compact body: stable speed and direction control in a machine that occupies little floor space.

This machine is an ideal choice for the pharmaceutical, food, powder, chemical and solid beverage industries. It can grind moist powder into granules of different sizes, and can also be used to crush dry powder that has been pressed into blocks into granules of the required size.

The screen mesh and granulating diameter are selected according to the required granule size. Models 250 and 300 cover 80 to 400 kg/h when crushing pressed blocks, so the machine can be matched to both pilot and production lines.

Satisfaction is guaranteed by our pledge to repair any manufacturing defect under normal operating conditions. Please keep the machine within its rated motor power and selected screen mesh; using the correct granulating diameter keeps output stable and extends the working life of the grinding and pressing blades.
