Droplet Fish Feed Crusher

fish feed crusher

Droplet Fish Feed Crusher Description
It is a crucial stage to crush the materials for making fish feed. The crushing process enlarges the surface area of the raw materials which can help to increase the solubility of the feed in digestive juice and promote the digestion of the animal. Meanwhile, the particle size of the materials will greatly influence the quality and complexity in later processing phase, such as granulation. As crushing process accounts for 50%-70% of the total power consumption in making compound powder feed, the crushing efficiency, to a large extent, determines the production cost. Investors take it as an important factor in valuing production cost, fish feed quality and price of the feed. Our droplet fish feed crusher is able to crush the raw materials of all granular animal feed, such as
corn, sorghum, grains, legume, smashed cake, and other materials. It is specially designed to the fine grinding of cellulose materials, and those materials with high content of waster and oil. It is an irreplaceable fish feed machine in floating fish feed, sinking fish feed and pet feed making process.

Main Parts of Droplet Pet Feed Crusher
Pedestal: the heavy-duty base supports and connects each parts of the feed crusher together. It decreases vibration, increases reliability and prolongs the service life of the feed grinding machine. After being ground, materials are discharged from the lower discharge port under the pedestal.
Rotor: it is comprised of main spindle, pin shaft, hammer pieces, hammer plate, bearings and bearing housing, being the main moving component of the pet feed crusher machine. As rotor is with high rotational speed, before installed with hammer pieces, it should be checked of Dynamic Balance to ensure the running is stable.

Operative Door: Open it when exchanging sieve plate or hammer pieces. The specially-designed screen press unit makes sieve plate replacement more convenient.
Abrasion-resistant Lining Plate: it is designed with replaceable parts, when worn to a degree, it must be changed to keep the broken fragments from entering the crushing chamber. The linking plate increases the longevity of the fish feed crushing machine.
Performance Characteristics of Droplet Fish Feed Crusher
This feed crusher is fabricated and welded together with thick and durable steel. The crusher assembly all adopt dual wear-resistant plate-with advantages of excellent abrasion resistance and changeable! The

abrasion of hammer pieces

electric motor and rotors of the crusher are installed on the same Heavy-duty Base. Hammer pieces are centrosymmetric, and rotators can work both forward direction and inversion after dynamic balance checking.

Fish Feed Crusher Working Principles
First, we put the raw materials into the crushing chamber through a feed hopper, and there are flailing hammers spinning quickly and close to a perforated screen. Then the broken materials are moved along the rotor outer-edge and go through a continuous collision and friction against hammer, toothed plate and sieve. Then the broken material is totally crushed. If the particle size is smaller than the holes on the screen after processing, feed powder can pass through the screen. Finally, the feed particles discharge to the fan, and products are blown through the cyclone and delivered into storage bags under the suction force of working fan.
