40TPH livestock & poultry feed mill plant with four sets SZLH420 pellet mill

Poultry & livestock feed is generally refers to the food for farmed poultry and livestock , it is the conventional feed in the feed classification.

Introduction of process:

The features of poultry & livestock feed are moderate grinding fineness(screen hole diameter 2-4mm),moderate curing and conditioning requirements(pellet mill adopts two layers conditioners),finished products with big pellet diameter(pellet diameter is around 2.5-4mm). Four sets SZLH420 poultry & livestock feed process is with 40tph capacity, it adopts three grinding section, two batching & mixing section, four pelleting section and four packing section. The total equipment power is around 1400kw. The construction area of the production area is about 24.5*22.5*35m, it equipped with 3T boiler. The whole line of the 40TPH four set SZLH420 poultry & livestock feed line is compact in design, reasonable in structure, meeting the requirement of environmental protection, and can be customized designed according to the requirements of customers.

Raw material:

The conventional raw material of poultry& livestock feed includes corn, wheat, barley, oats, sorghum, soybeans, soybean meal, fish meal, amino acids, mixed meals, whey powder, oil, meat and bone meal, grain, feed additives and so on more than 10 varieties of feed raw materials.

Process section introduction:

Raw materials receiving and cleaning section:

The function of cleaning is to clean up impurities in the raw materials, such as large impurities, including ropes, clods, corn cobs and other non-magnetic impurities and magnetic impurities such as iron nails to ensure the quality of the product and the safety of subsequent processing equipment. The raw materials receiving and cleaning section of the 40TPH four set SZLH420 poultry & livestock feed line contains granules feeding & cleaning and the powder feeding & cleaning.

Cleaning equipment:granules sifter SCY100,capacity 50-80T/H;powder sifter SQLZ90X80X110, capacity 30-50T/H.


Grinding section:

The effect of grinding section is to increase the specific surface area of the feed, which is beneficial to the digestion and absorption for the animals, improving materials processing performance. In this grinding section there is two hammer mills, and there are six bins above the hammer mill. Before the raw materials feeding into the bin, it need to remove the impurities by magnetic separator to ensure the safe operation of hammer mill. After impurity-removed, the material enters the grinding bins for grinding. The crushed materials are then transported by a screw conveyor into a bucket elevator and introduced into the batching bin through the distributor. The crushed materials are not only transported by screw conveyor, but also equipped with an auxiliary suction system, which not only saves energy consumption, but also prevents dust from overflowing, lowering the temperature of the materials and improving the grinding efficiency.

Grinding equipment(3sets):hammer mill SFSP668*1000,132KW,capacity 15-18T/H。


Batching & mixing section:

Batching designs formulations according to the nutritional needs of different animals, using specific device to accurately weigh the various ingredients. Mixing is an operation in which various feed ingredients are metered and blended under external forces to form a uniform distribution. This section adopts four batching scale and 36 batching bins, of which the micro ingredients are manually added equipped with test scale. After batching of material ingredients is completed, they enter the mixer for mixing, and finally the material is output through the conveyor and elevator.

Weigh equipment:batching scale PCS15/PCS10,batching accuracy≤3‰。

Mixing equipment:mixer SHSJ4,30KW,2000kg per batch,capacity 20-30T/H。mixing homogeneity CV≤7%。


Pelleting section:

The function of pelleting is to make fine crushed, easy flying dust, poor tastiness and difficult-to-ship feed into pellets by the action of heat, moisture and pressure in the granulation process to improve the good tastiness of the feed and reduce the feed-meat rate. Reduce feed waste and reduce environmental pollution. In this section, we adopt four double-layer conditioners pellet machines SZLH420, and eight bins designed above the pellet mill. After granulation, pellets enter into four coolers and crushers in sequence, and then passed through the bucket elevator to enter the rotary screener for sifting, the finished products enter the packing bin, and the rest returns to granulation or re-grinding.

Pellet equipment(4sets):SZLH420,110KW,capacity 10-12T/H for each pellet mill。Cooling equipment:SKLN6,capacity 10-15T/H for each cooler.


Packing section:

The powder and granules in the finished products bins which needs to be packaged will be packed by automatic packing machine, finished products that do not need to be packaged will be taken away by bulk truck.

Packing equipment:belt scale,screw scale, etc. Packaging range 20-50kg/bag,6-8 bag/min.


Auxiliary section:

40TPH four set SZLH420 poultry & livestock feed line is with dust removing system in the packing section for dust removing to improve the working environments. Oil adding system in the mixing section is to improve the feed tastiness.
