20t/h capacity per set pellet mill 60t/h Cattle and Sheep feed plant 
Jiangsu LiangyouZhengda Co., Ltd., specializing in the production of feed machinery and engineering, can provide customers withcomplete sets of equipment solutions for livestock feed (pig, etc.), poultry feed (chicken, duck, goose,etc.), ruminant feed (cattle, sheep, etc.), common aquatic feed (four major Chinese carps, etc.), special aquatic feed (shrimp, crab, etc.), extruded aquatic feed (floating and sink fish feed, shrimp feed, etc.), premix feed (including all kinds of additives, etc.), and pet food(cat food, dog food, etc.). to meet the different needs of customers.


Now take the 3 lines of SZLH678 cattle and sheep feed production line as a case, according to the process flow and each section to do the following introduction and description.

Definition of cattle and sheep feed:
Cattle and sheep is called ruminant Animal. Rumination means the incompletely digested food in stomach will be returned to the mouth for chewing again after some time since ate.  Ruminant animal is the animal digest in this way. Ruminant feed includes the feed for cattle, sheep, camel and etc., it also consist of concentrated feed and completed mixed daily feed.

Raw material:
The raw material of ruminant feed includes grains such as corn, wheat, barley, soybean meal (similar as poultry feed), it also includes crude fiber such as  green grass, hay, straw.

Introduction of process:
The features of ruminant feed( cattle & sheep feed) are coarse grinding fineness(screen hole diameter 4-8mm),low curing and conditioning requirements(pellet mill adopts single layers conditioner),finished products with big pellet diameter(pellet diameter is around 4-10mm). Three sets SZLH678 cattle & sheep feed process is with 50-60tph capacity, it adopts three grinding line, two batching & mixing line, three pelleting line and three packing line. The total equipment power is around 1670kw. The construction area of the production area is about 22.5*18*29.5m. The whole 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.


Process diagram:

Process section introduction:
Raw materials receiving and cleaning section:In this section, pellet feeding cleaning and powder feeding cleaning are separated independently and separate dust removal. Dust removal effect is good.
Cleaning equipment:granules sifter SCY100,capacity 30-50T/H;powder sifter SQLZ90X80X110, capacity 30-50T/H.








Grinding section: Because the fineness requirement for ruminant feed grinding is coarse grinding, this section adopts three small power hammer mills, and each hammer mill is equipped with two pre-grinding bins, which can grind different raw materials at the same time to improve the production efficiency. Before entering the bins, the impurities are removed by magnetic separation device to ensure the safe operation of the hammer mill.
Grinding equipment (3 sets): Hammer mill SFSP668×1000, 160kw, designed to produce 18-20t /h/ set

Mixing section: This section adopts 21 batching bins, two sets of batching systems simultaneously batching, and each batching system is equipped with two batching scales simultaneously batching. It is controlled by the batching program independently developed by our company to realize accurate fast and slow feeding, fast batching and high precision.
Weighing equipment: Dosing scale PCS20/PCS10, dosing precision: dynamic ≤3‰, static ≤1‰.
Mixing equipment (2 sets): mixer SHSJ4, (30KW, 2000kg/ batch), designed to produce 25-30t /h/ set.Mixture uniformity CV ≤5%.


Pelletizing section: This section adopts three single-layer conditioning pelletizer, and each pelletizer is equipped with two pre-pelleting bins, which is convenient to switch between varieties. After pelleting, they are respectively entered into the cooler and the elevator into the rotary screener in order to be screened, and the finished products are put into the packing bins, and the rest are returned to pelleting or bag receiving.
Pelleting equipment (3 sets): SZLH678, 220KW, designed to produce 20-22t /h/ set.
Cooling equipment (3 sets): SKLN10, 1.5+1.5+ 2.2kw, 10m3 capacity, designed to produce 20-25t /h/ set

Packing section: There are 6 finished product bins in this section, among which 4 bins are specially designed for storing finished product pellets material, and 2 bins for storing powder materials and pellets materials. Special anti-grading device is designed in the finished powder materials bins. The pellet or powder is automatically weighed and packed by the packing scale.
Packing equipment: Double hopper belt scale (can be used to pack powder or pellet), packing range: 20-50kg/ bag, 10-12 bags/minute.

Auxiliary section: Dust removal system to improve workers" working environment; Grease adding system, common mixer place added to improve feed palatability.

According to the needs of different customers, the scheme can be optimized:
1. The scheme adopts the single-point dust removal mode, that is, each rotary distributor (powder material) and pellet cleaner is equipped with a pulse dust filter, which has a good dust removal effect. Single point of dust removal is our company"s humanized design, which can provide a better working environment, but the cost increases. Customers can consider whether to use this configuration according to the actual needs;
2.The quantity of bins can also be adjusted according to the formula of customers, the characteristics of raw materials and other factors, so as to achieve the highest utilization rate and effectively control the production cost;
3.The dust collecting design at packing site can improve the working environment of workers, and customers can configure according to their needs.
