Fish Feed Mixer

Mixing can improve the uniformity of particle sizes form hammer mill to keep them in the same particle hardness, which directly improve product quality. Therefore fish feed mixing machine is the critical equipment in fish feed pellet production. Fish feed mixer with single shaft and twin-ribbon offered by our company, also named ribbon blender, is mainly applied to mix powdery feed materials to ensure a high quality of compound feed. And it is a well-performed feed mixer for fish and other livestock feed production plants.


Single Shaft Fish Feed Mixer Feature



1. High homogeneity: this kind of single shaft design reinforces convection, shearing, and mixing effects.
2. Moderate mixing and high uniformity, no segregation.
3. Human friendly: simple and reasonable structure, convenient maintenance, reliable, safe, effective and less investment. The mixer also can be equipped with jacket to facility heating and cooling materials. At the same time, thermal insulation materials also can be installed as required.
4. Multiple application: it can be used for mixing feed, food additives, binder, silicone rubber, pigment, printing ink, paraffin, resin, vanishing cream, ointment, detergent, etc; and also can be used for mixing viscous fluid and thick, pasty and granular materials.
5. Used for mixing of: powders with powders; powders with liquids
6. Large open layout, a quick feed, little residue, to meet the needs of adding the liquid.

Main Purposes of Using Feed Mixing Machine
● To distribute materials with different characteristics as evenly as possible. A new homogeneous material with different properties results.
● Adding water during the mixing process to help improve stability of particles. Pellets made by high moisture particle sizes are with low hardness, squishy and good palatability,
● Adding grease in the mixing powder to prepare for decreasing the hardness of feed pellets.

Fish Feed Blender Working Principle


Ribbon Blender(also called ribbon mixer) consists of a U-shaped horizontal bucket and a specially fabricated ribbon agitator. The agitator rotates with minimum wall clearance in a U-shaped vessel. A ribbon agitator consists of an inner and outer ribbon which effects a counter flow mass movement with random motion in radial and axial directions: the outer ribbon moves materials in one direction and the inner ribbon moves the materials in the opposite direction. The ribbons rotate and moves materials both radially and laterally to insure thorough blends in short cycle times. That’s to say, mixing action in the double ribbon blender is created by the following 3 factors:
1. Conveying of product by one ribbon from left to right
2. Counter flow of product by the second ribbon
3. Exchange of product between the two ribbons

Reasonable Operation of Fish Feed Mixer
1. Turn on feed ribbon blender, and then check its running direction. Rotating on opposite directions is not allowed.
2. Checking the processing volume which should not more than dischargeable capacity listed on the guideline.
3. Remember to discharge the lubricant and clean the oil tank after the mixer`s first operation of 15 days; every 3 months change the lube in the speed reducer, and every 2 months lubricate the grease on the bearing. The above is adjustable based on the working condition.
4. Light repair of the feed mixing machine is needed after 1800-hour running to check the lubrication points and replace the quick-wear parts; heavy repair is needed after 4000-hour running to disassemble to check and clean all the components, replace quick-wear parts, and adjust standard units.

We offer three capacities of mixers as follows. Before select a mixer, please consult with us to determine the optical size for your powder blender. Working volume is the volume of material to be mixed and can be determined by dividing your batch size and the bulk density of your ingredients. We can use the batch size and bulk density information on your application data sheet to help you calculate the mixer’s working volume.
