Fish Feed Crusher

Fish feed grinder is a machine specialized in crushing materials by the collision between the high-speed hammer and materials. Raw materials in feed crusher are crushed into suitable particle sizes for feed mixer procession. Final size of materials can be controlled by inserting a screen with different sized holes. With competitive price, simple structure and high efficiency, animal feed crushing machine is mainly employed in the farm, middle sized feeding factory or for family use.


Fish Feed Crusher Features
Fish feed crusher consists of feeding port, top engine block, bottom engine block, rotor, screen sieve, hammer blades, working fan, feed sucking pipe and etc. And the cyclone and storage bag can be equipped as customers required.


● Easy to operate, low specific power consumption, accurate and consistent product grinding
● Reasonable design: final size of materials can be adjusted according to replacing the right screen sieve. Moreover the ability to change screen size, and the option of a variable speed frequency drive control, enable the crusher to processing a variety of materials.
● Core part-hammers are made of high quality carbon alloy steel, which is durable and wear-resistant. Long life and durability.


Fish Feed Crusher Application
The fish feed crusher is widely employed in farm, middle-sized feeding factory or for family use. This feed grinder can be used for many different particle reduction:
♦ Agricultural materials, such as corn, maize, corn stalk, peanut shell, dry grass, cotton stalk, etc.;
♦ Pharmaceutical and industrial materials, such as Chinese medicine crops, quartz, coal, coal residue, woods, etc.

Fish Feed Crusher Working principle


1. The raw material enters into crushing chamber through feed hopper and is held there until it is reduced to the size of the openings in the screen , and there are flailing hammers spinning very fast and close to a perforated screen.
2. Under the drive of airflow, the broken material is moving along the rotor outer-edge and has a continuous collision and friction against the hammer, toothed plate and sieve, then the broken material is crushed. Once the particle size below the diameter of the screen holes, feed powder will pass through the screen.
3. The feed particle discharge to the fan, and products are blown through the cyclone and delivered into storage bags under the suction force of working fan.

How to Replace the Hammer and Screen
Hammer blades and screen sieve are main and crucial parts in grinding production, which plays prominent role in affecting the capacity and quality of feed particles. Especially screen siever accounts for 70% of what determines the finished particle size. As easily worn components, hammer blades and siever should be checked whether they are worn after a certain working period. If worn, you should replaced them to ensure great grinding efficiency.
For specific sized feed particles based on the production demand, you also need to replace the siever.
1. Open the crusher case                                  2. Pull out of the shaft



3. Take the shaft out and change hammer             4. Take sieves out and replace the new one
