DWM high-efficiency pulverizer

DWM high-efficiency pulverizer is widely used in the pulverization and granulation of various antibiotic raw materials, aseptic injection crystallization products, large-scale freeze-dried products, peptide products and various aseptic raw materials.

Under the centrifugal force of the high-speed rotating pulverizing knife, the particles of the pulverized material are thrown radially, and the particles and the knives, the particles and the inner wall of the pulverizing chamber, and the particles and the particles are sheared and impacted at high speed, and the particles satisfying the requirements passes through the mesh hole along the tangential direction until the pulverization of all materials is completed.

The output and particle size of the product are determined by factors such as the type of equipment, the feed rate, the speed of the pulverizing knife, and the mesh hole. These parameters can be changed to meet different comminution yields and particle size requirements.

● Equipment features

1, Easy to disassemble, clean, sterilize

All the components in the mill chamber - mill knives, sieves, seal rings, chamber, etc. can be easily disassembled for cleaning and sterilization. The mill knife can be reversed and assembled to suit the crushing materials of different types.

2, Compact, simple, easy to move.

3, Unique constant feeding and "lock gas" device

The imported original air motor uses compressed air as the power source to drive the constant feeding valve to rotate. In addition to uniform feeding, there is a “lock gas” function which holds the first pass to prevent powder return.

Air motor features: smooth operation, stepless speed change, forward, reverse, explosion-proof.

4 Gas balance tube device

The pressure at the feed port is balanced with the gas pressure at the discharge port, and the second pass to prevent back powder is held.

5, specially designed S-type buffer hopper

The specially designed S-type buffer hopper has a “self-priming” function that holds the third pass to prevent back powder.

6. Specially designed air sealing device

The seal between the drive shaft and the cavity wall uses an advanced air sealing device that uses a clean compressed air to form a uniform air ring at the seal to block the powder from flying outward. Thereby, the phenomenon of "chip falling" which may occur in the mechanical seal at high speed is avoided.

7. Micro-powder capture device

For some special materials, such as some material with a bulk density of less than 0.25Kg / L, occasionally a small amount of "powder gas" overflows from the gas seal. At this time, it is necessary to install a micro-powder trap, and a small amount of "powder gas" will be collected into a trap or filter bag by a hose connected to the gas seal.

It is worth noting that: processing 100Kg material , usually less than 2g of fine powder collected!
