Premix feed mill equipment usually includes the following main parts: raw material storage and transportation system, batching system, mixing system, additive system and finished product packaging system. These parts work together to ensure a smooth production process.

  1. First of all, the raw material storage and conveying equipment is the starting point of the premix feed mill. It is responsible for storing various feed ingredients and delivering them to the batching system when needed. The type and quantity of raw materials stored should meet production needs, and the conveying system should ensure the uniformity and stability of raw materials to avoid fluctuations in the production process.
  2. The batching equipment is a key part of the premix feed processing line. It mixes various raw materials together in proportion according to the production formula and ensures the accuracy and uniformity of the ingredients. Batching systems usually use automated control technology to improve production efficiency and product quality.
  3. The mixing equipment is a device that fully mixes and homogenizes the mixture output from the batching system. It usually uses a horizontal or vertical Stainless Steel Feed Mixer to ensure uniformity and stability of mixing. The design and manufacture of mixers should take into account the characteristics and production capacity of the materials to ensure that the quality of the feed produced meets the requirements.
  4. Additive equipment is device that add appropriate amounts of additives during the mixing process. The type and quantity of additives should be selected and controlled according to production needs to ensure that the feed produced meets food safety and nutritional requirements.

FAQs of premix feed mill

What are the mandatory requirements when designing premix feed mill?


Dust control

Most of the materials processed in the premix feed mill workshop are powders with very fine particle sizes that are easily inhaled into the human body, which is detrimental to the health of workers and cannot pass environmental protection requirements. Therefore, dust removal devices must be installed at each feeding port and packaging port for directional dust removal.


Made of stainless steel

Regardless of the process, starting from the premix feed mixer, adding hoppers for small materials to packaging, all parts in contact with the materials need to be made of stainless steel, which can effectively prevent corrosion.


Automatic batching

Premixes have very high requirements for batching accuracy. The accuracy of the batching scale must reach the standard of 0.1% dynamically and 0.3% statically.



The effective volume of the main mixer in the premix workshop is at least 1 cubic meter. It uses a stainless steel double-shaft paddle mixer and a single-shaft paddle mixer. The mixing efficiency is high, the residue is low, and the uniformity is high.


Automatic packaging

It is recommended that the premix feed mill workshop use automatic packaging and palletizing. Manual packaging not only has low precision and efficiency, but also increases labor costs and serious dust leakage, affecting the health of operators.

Before premix companies build new premix feed production plants, they need to scientifically select their own processes and equipment in advance, which will have a great impact on subsequent production.

What are the issues that need to be paid attention to when building a premix feed mill?


Adopt advanced formula

Formula is the core premix feed mill technology of premixed feed. It needs to be carefully proportioned by professional animal nutrition experts based on the characteristics of animal growth and nutritional needs at each stage, as well as many influences such as the external environment.

The ratio of active ingredients to diluent, the ratio of various trace elements, and the ratio of active ingredients in the premix should be just right. Sufficient scientific basis and practical experience are required. Otherwise, serious production consequences will easily occur.


Select high-quality raw materials

The basic requirements for high-quality raw materials are high purity, no harmful substances, and the content of active ingredients must be actually measured. When selecting trace element raw materials, the content, particle size, crystal water, toxic and harmful substances, etc. of the ingredients should be considered.

Medicinal additives should also pay attention to safety issues. In addition, some additives themselves will affect other ingredients, so special attention should be paid.


Use the best carrier and diluent

The carrier should be selected with strong stability, moderate particle size, and good mixability with complete feed. The carrier particle size is between 0.17~0.59mm, and the moisture content is controlled at 8%~10%. Commonly used carriers include: corn, bran powder, stone powder, salt, etc.

Diluents are substances that reduce the concentration of active substances in a premix and reduce reactions between active ingredients. The water content of the diluent should be less than 10%, the particle size should be between 0.05~0.6mm, and it must be edible and harmless to animals.


Use high-precision production equipment

Scientific proportioning is the first step, and the subsequent steps need to be achieved by accurate metering of ingredients. Premix production has high requirements for the accuracy, precision, and stability of various types of metering equipment, and requires the configuration of technologically advanced premix feed mill equipment.

And it is necessary to strengthen the daily management and regular calibration of relevant equipment.


Mix evenly

The mixing section of the premix is a key part for premix feed mill. If the uniformity is poor, it means that the actual content of the animal intake does not match the formula, which directly affects the feeding effect.

Therefore, equipment, mixing time and appropriate carriers or diluents must be scientifically selected to strive for uniform mixing. Especially for some ingredients whose safe measurement and poisoning measurement are not much different, insufficient mixing uniformity will directly cause feeding accidents.

With the continuous advancement of technology and increasing application requirements, premix feed mill design and manufacturing technology are also constantly developing and improving.

In the future, with the application and development of new technologies such as intelligence, automation and greening, premix feed production line equipment will be more efficient, reliable and environmentally friendly, providing better support and guarantee for the development of the feed industry.
