WFJ micro grinderThe ultrafine pulverization equipment mainly includes micro pulverizers, fine grading, material conveying, medium separation, dust removal, dehydration, control, detection and other process equipment. The equipment and instruments constitute a complete micro pulverization process, with open and closed circuit micro pulverization in the process layout. The current micro crushing methods mainly include mechanical crushing, including high-speed mechanical impact mills, suspended roller mills, ball mills, disc mills, vibration mills, airflow mills, and colloid mills. In feed processing, special feed factories such as fish and shrimp commonly use micro crushers with large output and coarse product particle size. In this situation, the crushed materials are mostly organic compounds such as corn, fish meal, and soybean meal, and the particle size is not required to be too fine, but the yield is relatively high.
1、 Working principle:
WFJ micro grinderMainly composed of a classifier, brake, dust collector, butterfly valve, and fan to form a micro powder unit. During operation, raw materials are uniformly and quantitatively fed into the crushing chamber through the feeding screw from the feeding hopper, and are crushed by the impact of the stirrup hammer and the friction of the toothed plate and sieve. The materials that meet the requirements for crushing particle size are sucked out of the crushing chamber through the sieve mesh under the negative pressure suction of the system, and then enter the wind classifier through the air duct to classify the crushed materials. The coarse materials are then re crushed in the feeding hopper; Qualified fine materials are then sent to Sakron to achieve gas material separation. The crushed finished product is discharged through the air damper below the brake cylinder. The airflow containing dust is removed by a pulse dust collector and discharged into the atmosphere by a centrifugal fan through a butterfly valve. Butterfly valves can be used to control the secondary air intake to regulate the air pressure and volume within the system.
2、 Structural features:
1. The motion system of the machine rotates continuously at high speed in one direction, driven by an electric motor, a belt, and a movable disc for high-speed rotation. It adopts a single belt rotation and has smooth transmission during high-speed rotation.
2. The front cover of the machine must be opened after shutdown to clean the interior of the machine and ensure the cleanliness of the working surface.
3. The crushed material can be directly discharged from the belly of the machine.
4. The degree of pulverization can be achieved through different aperture sieves.
