About Premix feed mill
Premix plants are facilities within feed mills that are responsible for preparing precise combinations of micro-ingredients, such as vitamins, minerals, amino acids and additives, essential for animal nutrition.
These facilities have equipment for dosing, mixing and storing ingredients in specific proportions, ensuring their correct incorporation into the feed manufacturing process.
First of all, let’s understand what is premix. Premix is one or more kinds of additives for mixing with compound feed. People often regard premix as the heart of compound feed, which shows the important role of premix in compound feed.
However, premix is not simply a combination of different raw materials, it is a highly technical product. It is a highly technical product, because its composition is extremely complex and many kinds of small quantities, physical and chemical properties and the great difference, but also in the safety and stability and other aspects of the problem, which increases the complexity of the premix plant production premix.
To build a premix plant to produce high quality premix products, it is necessary to comprehensively consider the factors of raw material procurement, formulation design, production management, quality control and other aspects.

- Every detail, from process flow to equipment layout, is carefully planned to work perfectly with a feed pellet machine for sale, delivering a clean, safe, and eco-friendly feed production system that truly meets your needs and helps your business thrive.



Premix Feed mill Process Requirements
Dust control
The materials handled in the premixing workshop are mostly powders with very fine particle size, which can be easily inhaled into the human body, which is unfavorable to the health of the staff and can’t pass the environmental protection requirements. Therefore, dust removal devices should be set up in each feeding port and packing port for directional dust removal.
stainless steel production
No matter what kind of process, from the premixer mixer, from the small material adding bucket to packing, all parts in contact with the material are made of stainless steel, which can effectively prevent corrosion.
The pre-treatment stage of raw materials
Pre-mixed materials for the dosage precision requirements are very high, the dosage scale accuracy must reach the dynamic 0.1%, static 0.3% of the standard.
premix feed Mixer
The effective volume of the main mixer in the premixing workshop is at least 1 cubic meter, using stainless steel double-axis paddle mixer and single-axis paddle mixer, with high mixing efficiency, low residue and high uniformity.
premix feed Automatic packing
It is recommended to use automatic packing and palletizing in premix workshop. Manual packing is not only low precision and low efficiency, but also increase labor costs, dust spillage is serious, affecting the health of workers.
Premix feed mill production process
— Richi Machinery —

Premix plant on the production process and equipment requirements are extremely strict, because the slightest difference may cause inaccurate dosage, resulting in waste of raw materials or the production of premix out of the effect is not good.
The above figure is the flow chart of 5T/H automatic batching premix production line, through this flow chart we can roughly understand the production process of premix feed plant.
Premix production process is affected by raw material varieties, formulas, production types, plant structure, capital and other factors, according to the actual situation of different customers need to be directed to design, design the program that best meets their own.
Generally speaking, the production process of premix feed plant mainly includes raw material receiving, raw material cleaning, batching, mixing, packaging and so on.
Raw material receiving
Firstly, the materials prepared according to the formula will be stored in the raw material warehouse. The receiving equipment mainly includes weighing system, inspection instrument, unloading system, cleaning system, dust control equipment, receiving conveyor, fabric machine, hopper and so on. It is worth mentioning that the equipment of our premix plant is made of stainless steel in the contact part with the material, which will not cause pollution to the material.
Cleaning section
After receiving the raw materials, it is necessary to clean the raw materials to remove impurities. This process can clean out the impurities that may be contained in the raw materials, but also can sort out the coarse raw materials that need to be crushed.
Crushing section
Next, an animal feed hammer mill is used to reduce the particle size of the material to the required screening standard, which helps to ensure the quality of the premix.
Batching section
Batching is a critical step in the premix. The accuracy of the dosage determines the quality and usability of the premix. Therefore, this process must be strictly controlled, focusing on the choice of processing technology. According to the premix formula, add the materials to the weighing bin in order and weigh them.
Mixing section
Mixing uniformity is also a key indicator to test the quality of premix. As a highly concentrated intermediate product, premix is composed of various trace elements, and the proportion of each component varies greatly during the processing of premix, so it is necessary to choose a high-efficiency, low-residue feed mill mixer as well as a reasonable processing technology.
In order to make the premix mixing uniformity higher, the mixing part should be divided into two steps: micro-mixing and macro-mixing. Macro-mixing is both the mixing of all the components of the premix with the reagents of the carrier in the interstitial mixer, which is a typical function of an animal feed mixer machine. Micro-mixing, on the other hand, refers to the mixing of trace ingredients with a weight less than 1% of the mixer capacity.
Packaging section
After mixing, the production of premix is basically completed. The next step is the packaging section of the premix. In addition to maintaining the image of the product, the packaging section pays particular attention to maintaining the stability of the trace elements and protecting the integrity of the premix.

FAQ about the premix feed mill
Processing points for feed mixing plant
Premix as a more sophisticated additive feed, there are more factors that need to be strictly controlled during processing. On the one hand, because premix is more expensive, it is necessary to reduce the waste of raw materials in the process. On the other hand, premix is mainly mixed with feed to supplement the nutrients that feed can provide.
1. Selection of formula
First of all, it is necessary to mix the appropriate premix formula according to the different seasonal environments of different animals. Accurate and professional premix formulation is the key to premix production.
2. Accuracy of dosing
After the formula is finalized, the accuracy of the ingredients must also be strictly controlled. Most of the materials involved in premix plant are trace ingredients, with very small dosage, some even extremely trace, and the safe dose is very close to the poisonous dose, such as selenium, so the dosage precision requirements are very high. A small dosing error is a prerequisite for the production of high quality premixes. In order to achieve this goal, we must use high-precision dosing instruments, such as electronic scales; design a reasonable weighing process, such as the use of multi-stage dilution and mixing, group dosing process, and even micro-ingredients of certain levels of micro-ingredients can be weighed with micro-balance inside the preparation room to ensure that the weighing is accurate.
3. Mixing uniformity
Premix processing requirements for mixers are also relatively high, mixing uniformity is an important indicator of the quality of premix processing. Reasonable dosage system, to ensure the standard of its total amount, but it is very likely to be mixed unevenly, and still can not meet the dosage system, to ensure the accuracy of its total amount, but a lot of possible mixing unevenly, and still can not meet the quality indicators. For premix, because it is a highly concentrated intermediate product, it has to be continuously diluted and expanded in the post-processing, so the unevenness of the former section may turn into incorrect proportioning in the latter section of the process. This requires both the selection of high-efficiency, low-residue mixer, but also must design a reasonable mixing process.
4. Selection of processing technology
Premix how to process, the specific processing process to find a professional premix plant. Under the premise of helping to ensure the quality of the finished product, the processing process should be as short as possible, and can reduce the pollution and grading caused by long-distance transportation.RICHI Machinery’s professional team can customize the premix plant process for you. All you need to do is to tell us your raw material, your production requirements and we will customize your premix plant to meet your actual needs.
5. Configuration of processing equipment
In premix, in addition to a portion of grain-based raw materials or their by-products, the rest of the varying degrees of chemical activity, some even corrosive effects, and in turn, the materials used in the manufacture of the equipment may also affect the potency of certain ingredients. Therefore, where the high concentration of active ingredients in contact with the processing equipment, piping and hoppers, etc. are appropriate to choose the right material, such as stainless steel.
6. Packaging
Packaging not only affects the product image, but also has an impact on the quality of the premix, especially in the premix of some trace components in the storage process will gradually change, lose activity. For this reason, packaging materials should be non-toxic, harmless, sturdy, moisture-proof, light-proof materials, tightly packed, beautiful, strictly prevent mixing.
Difference between premix feed mill and Powder feed mill
Pre-mixed feed mills and powder feed mixing plants are both related and different. They differ mainly in:
1. Raw materials are different:
The raw material of premix plant processis one or more trace elements composed of additives. The raw material of powder plant is all kinds of feed ingredients.
2. Usage is different:
The premix produced by the premix plant is mainly used to dilute the additives and feed mixes evenly, can not be directly used for feeding animals. The powdered feed produced by the powder feed mixing plant can be used directly for feeding animals.
3. Processing process is different:
Premix plant processing process is mainly a variety of trace elements additives and carriers or diluents for mixing, the main point of processing is accurate ingredients, mixing evenly. The key machines and equipment used in the premix plant process are mixer and dosage scale. The processing process of the powder plant is to prepare the raw materials first through the grinder for crushing, and then through the conveyor equipment to the mixer for mixing, the mixing process can be added to the premixer mixing uniformly, the generation of direct full-price powder feed.
4. The host equipment is different, and the material is also different:
The host equipment of premix plant is crusher, mixer, dosing scale, all stainless steel silo. And the host equipment of powder plant is crusher, mixer. The premix plant has higher requirements on the material of the host equipment, because the premix plant has expensive raw materials and high requirements on the material of the processing equipment.
5. price is different
It can also be seen that the price of premix plant is higher than the price of powder plant. Because the configuration of the production line premix will have higher requirements.
