Double Shaft Crusher, PDWB
Production of powders with narrow particle size distributions from brittle and crystalline materials.
The ORIGINAL PALLMANN Horizontal Knife Mill, type PSRH, called ,Biber“, with an hydraulic feed system is best suited for the size reduction of most various types of plastic waste. The Horizontal Knife Mill will scredd such as purgings, waste from the production of pipe-, profile and film, pressed bales of plastic bottles, film-, fiber and carpet waste and many
The Horizontal Knife Mill is usually installed on the production floor or in a pit. Typical feeding method is by hand, with a belt conveyor, a forklift, a crane or other mechanical devices into the feed hopper.
The feed material is automatically fed into the rotor by means of a hydraulic, intermittently moved live bottom. The material is size reduced between the rotor- and stator knives. A screen keeps the material in the grinding chamber until the desired final size is achieved. The finished product is discharged straight down and is transported further either pneumatically or mechanically, depending on the material condition or the downstream processing step.
Advantages & Features
- Production of narrow particle size distributions possible
- Direct drive of rolls by gear motor or hydraulic motor
