Dual-line SZLH420(20tph) Ruminant feed production line

Ruminant feed includes the feed for cattle, sheep, camel and etc., 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 consist of concentrated feed and completed mixed daily feed.

Jiangsu Liangyou Zhengda Co., Ltd., specializing in the production of feed machinery and engineering, can provide customers with complete 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 Dual-line SZLH420(20tph) Ruminant feed production line as a case, according to the process flow and each section to do the following introduction and description.


 Dual-line SZLH420(20tph) Ruminant feed production line


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 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). Double sets SZLH420 ruminant feed process is with 20-30tph capacity, it adopts two grinding line, one batching & mixing line, two pelleting line and two packing line. The total equipment power is around 700kw. The construction area of the production area is about 21*17.5*28m and equipped with 2T boiler. 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 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 SCY80,capacity 20-30T/H;powder cleaner SQLZ60X50X100, capacity 10-15T/H.

Grinding section: 

Because ruminant feed grinding fineness requirements are very thick,

this section adopts two small power hammer mills, and each sets allocated with two pre-grinding bins, which can grind different materials at the same time and improve the efficiency. Before entering the bins, the impurities are removed by magnetic separation device to ensure the safe operation of the hammer mill.

Grinding equipment(2sets): Hammer mill SFSP668×800, 90kw, designed to produce 10-15t /h/set

Batching and mixing section:

This section adopts 16 batching bins. Two sets of batching system work at the same time. It is 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: mixer SHSJ4, (30KW, 2000kg/ batch), designed to produce 20-30t /h. Mixture uniformity CV ≤5%.

Pelletizing section: 

This section adopts two sets of single-layer pelletizer, and each set 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. The sieved out powder material back to granulation, sieved out large particle material back to crumbler.

Pelleting equipment(2sets) : SZLH420, 110KW, designed to produce 8-15t/h/set(Ruminant feed pellet is large).

Cooling equipment(2sets) : SKLN6, 1.1kw, 6m3 volume, designed to produce 10-15t/h/set.

Packing section:

There are 4 finished product bins in this section, 3 bins of them are specially used to store pellet feed; There is also one bin for powder material and pellet material. The powder material finished products bins are designed special anti - grading device. The pellet or powder is automatically weighed and packed by the packing scale.

Packing equipment: Belt scale (it can be used as powder feed or granule feed), packing range: 20-50kg/ bag, 6-8 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. According to customer demand, finished product bulk bins are optional.
