1-160 t/h Pig Feed mill Overall Design

With the production workshop as the core, on the basis of the workshop design, the whole pig feed plant design is carried out. Before the design of the whole pig feed production plant, it is necessary to determine the operation and management mode, work process, and resource allocation of the pig feed plant after completion.

On the basis of the feasibility study and preliminary design, combined with the use functions of storage, office, living and supporting facilities, consider the future development needs, determine the design content, and design detailed construction drawings according to the current national design specifications and requirements.

15 tons Pig Feed mill design
20 tons Pig Feed mill design
30 tons Pig Feed mill design

When designing, the storage capacity and storage method compatible with the production workshop are the core of the design, the office and living building facilities are the focus of the design, and the auxiliary supporting facilities are the key to the design. There should be a clear demarcation between the production area and the office and living area.

  • Generally speaking, the packing room should be designed in the finished product warehouse; two large and small scales should be used. If there is one scale, its weighing range should meet the requirements of the largest vehicle measurement;
  • The initial inspection of raw materials is best carried out outside the pig feed mill factory. After sampling, the raw materials can directly enter the inspection laboratory for blind inspection;
  • The unloading of bulk raw materials should adopt a hydraulic flap mechanism as much as possible, and the unloading space should be well sealed, and the raw materials in bags should be stacked and stacked with pads;
  • Bulk raw materials should consider the storage of corn, wheat, soybean meal, cotton meal, rapeseed meal, stone powder, DDGS, etc., and the silo group can be built in stages according to the need to reduce the investment in fixed assets;
  • The storage of bulk raw materials has two storage methods: cylinder silo and chamber silo, which can be selected according to material characteristics and needs;
  • The distance between the transformer and power distribution room and the pig feed mill workshop with the largest power should be close; considering the operating cost and meeting the demand, the tonnage of the boiler should not be too large or too small, and it should be the closest to the workshop;
  • Machine repair room, spare parts warehouse, new woven bag warehouse, waste woven bag warehouse, workshop office, changing (hat) room, bathroom, forklift storage room, driver rest room, toilet, etc. should be designed near the workshop, and the logistics should be smooth;
  • The production area should be separated from the office and living area, the living area should be separated from the office area, the business hall should be separated from the administrative office area, and the car parking area should be separated from the bicycle and motorcycle parking area.

4 t/h pig feed mill process flow::

  1.  Initial cleaning and screening of raw materials: All the raw materials are bagged raw materials, and the raw materials are temporarily stored in the raw material warehouse after purchase. Raw materials such as wheat, corn, and meal need to be crushed, while powders such as fish meal, stone powder, and bone meal do not need to be crushed.
  2.  Raw material crushing: This process is mainly carried out for the pellets that need to be crushed, and the materials in the crushing bin enter the crusher for crushing.
  3. Batching mixing section: The raw materials are conveyed by the batching auger according to the formula amount and batching sequence set by the system, and then enter into the batching scale for cumulative measurement. Mixer to mix.
  4. Cooling section: The pig feed mill project products include powder and pellet forms. After the ingredients are mixed, the powdery product can be obtained, and the powdery product directly enters the finished product warehouse; after the ingredients are mixed, the granular product can be obtained through the granulation process.
  5. Grading and packaging section: the cooled finished pellet product enters the plane rotary grading screen, and completes the three-stage sieving, and the finished product entering the finished product warehouse passes through the vibrating screen and packs after classification storage. The powdery finished products that do not need to be granulated directly enter the finished product warehouse after completing the ingredient mixing, and are packaged and put into storage after vibrating screening.

Faqs of starting complete pig feed mill


How to determine the scale of raw material warehouse?

Raw material warehouse scale according to inventory demand and pig feed mill project operation capacity:

Flat storage area instead of bulk silos required more ground area. So, size of warehouse shed should match the project capacity and raw material storage. Practically 1 MT of material requires 5-6 square feet of area at 15 feet stacking height on maize density.

For example: if we have to store raw material stock for 2 months and our daily production is around 100 MT we need ; 100 x 25 days x 2 = 5000 MT of storage for 5000 MT storage on maize density we need minimum space of 28, 000 – 30,000 square feet.


How to prepare for future expansion for pig feed mill?

Selecting layout with no room for expansion is a mistake. Even with the best planning, most successful plants will make changes in future years that could not have been foreseen.

expansion for pig feed mill

Therefore, it is wise to allocate some area of the site for future growth and expansion And always select the location of pig feed mill in such a way that there should be space for expansion towards the raw material godown (In direction of chain conveyor). Also provision can be kept for bulk silos.


How to consider the supply of water, electricity, labor and other resources?

Water is necessary for boilers, toilets and fire protection. However, if it is not available from utility, a well on the property may be necessary. In this case, underground water availability will need to be investigated. Sometimes both sources are used in the same plant.

4-5t/h pig feed plant design

A public sanitary sewage connection is desirable, but properly installed septic tanks and drain fields work very well in remote areas.


What are the considerations for personnel safety and fire protection of pig feed mill?

Roads Should Be PROVIDED in A Symmetric Manner to Serve All ARLAS Requiring Access for the Operation, Maintenance and Fire Fighting.

Should be provided for each operating area. Fire control room may be in the security room/administrative building. High Tension (HT) line and HT sub-station(s) shall be terminated / located outside the operating area.
