Structural Features and Working Principle on SWFL82B

As the best grinding machine manufacturer, Muyang has made its efforts to make its all machines with high qualities. SWFL82B Vertical Pulverizer, as a new type of equipment for large-, medium- and small-sized feed mills, is with full equipments which make it more efficient.

SWFL82B ultra-fine pulverizer mainly consists of a stander, a grinding system, a grading system, a feeding system, a pneumatic opening mechanism as well as a driving part for grinding of the principal grinding machine and a motor driving part for grading. The grinding system is composed of a main shaft, a grinding disc, a geared ring and a grinding chamber; the grading system is composed of a grading impeller shaft, a grading impeller, a convex cover and a discharge chamber. The main motor runs in vertical driving way; the frequency conversion motors with frequency converters are used for both grading and feeding, so as to realize speed regulation and remote control.

After preliminary cleaning and magnetic separation, the raw materials (＜1 mm) enter the grinding chamber from the screw feeder for grinding. Under a high-speed rotation of the grinding disc and an action of centrifugal force, the materials are ground by impacting of the hammer knives on the grinding disc, and fly to the surrounding geared ring in a very high speed. Since the clearance between the hammer mills knives and geared ring is very small, the airflow between the hammer knives and geared ring varies instantaneously with the change of tooth forms. The materials in the clearance are further ground under the repeated action of alternating stress. The ground materials are taken by airflow to the space between the inner wall and the dividing flow cover from the grinding disc, and then enter the grading chamber; the materials are graded under the collective action of rotary grading impeller, wind power and centrifugal force, and the separated course materials return to the grinding chamber for regrind from the inner chamber of the dividing flow cover, while fine materials (finished products) are sucked into the grading impeller and enter the discharge chamber, and then enter the collection system from the discharge outlet.
