This mode constitutes three grades of pulverizing, material enters into one-level precomminution chamber by feed hopper, the flywheel that is rotated is at a high speed pulverized cutter precomminution, the secondary pulverizing chamber is sent in reinforcing, and material is through pulverizing, and fine powder is discharged from mesh, meal is by the spin-up that makes progress, enter three grades of precomminution chambers, after the intensive flywheel pulverizing cutter that is rotated was at a high speed further pulverized again, one of the material of releasing together with one-level precomminution chamber entered the secondary pulverizing chamber ...
2, described reducing mechanism comprises Crushing net and pulverizes cutter, and the pulverizing cutter is installed in flywheel and pulverizes on the power transmission shaft of cutter, so just constitutes secondary and pulverizes.Material enters into precomminution chamber (one-level pulverizing) by feed hopper, the flywheel that is rotated is at a high speed pulverized cutter precomminution, the pulverizing chamber (secondary pulverizing) of reducing mechanism is sent in reinforcing, material is sheared with the generation of pulverizing wire side by the pulverizing cutter of rotation at a high speed and is pulverized, under the effect of centrifugal force and shearing force, fine powder is discharged from mesh, and meal is pulverized cutter by flywheel and advanced the secondary pulverizing chamber again by the pulverizing cutter of at a high speed rotation spin-up backward.
This secondary grinding mode can be horizontal installation, and promptly described power transmission shaft level is installed; Also can be inclined and install, promptly described power transmission shaft tilt to install (with the angle of horizontal direction be that 20~30 degree are advisable).
Advantage of the present utility model:
Mass transport, precomminution, pulverizing are incorporated into one, have realized multistage pulverizing, have improved the production capacity of pulverizing chamber, have improved operating efficiency.
