Characteristics

The use of dual channel tangential air intake avoids the velocity non-uniformity of the rotating field in the radial flow field.

Effectively control the final moisture content and fineness by coordinating and unifying the swirl blades and inlet air velocity.

The rotating blade has a unique arrangement structure, characterized by low wear, wide contact surface, and high cutting force.

Skilled in handling heat sensitive materials, the bottom of the host belongs to the high-temperature zone, where the gas velocity is high and there is a cooling water protection device to avoid the possibility of material coking and discoloration.

Low system resistance, high thermal efficiency, good operating environment, and low labor intensity.

The host adopts a new sealing structure, which extends the service life of the host bearings and the bearing seat is equipped with a water isolation sleeve circulation cooling device.
