Triple set SZLH420(20tph) normal fish feed production line

Technological characteristics and introductions:

RM receiving and cleaning process:

In this process, the clean system for granule receiving and cleaning is separated from powder receiving and cleaning, dust collection are individual which is with the better effects.

cleaner: granule precleaner SCY100, output 30-40t/h, powder cleaner SQLZ90×80×110, output 30-50t/h.

Grinding process: 

we use 3 set hammer mill with different power according to the different material characteristic.  2 grindings bins are equipped for each hammer mill to cross exchange different raw material crushing ; The impurities could be removed from raw material by magnetic separation equipment before grinding bins to ensure the safe running of hammer mill. 

Grinding equipment(3sets): hammer mill SFSP668×1000, 160KW, output 6-8t/h(1set), hammer mill SFSP668×800, 110KW, output 4-4.5t/h(2set)

Batching and mixing process:

In this process, we use 36pcs batching bins including 4 common bins.  For each batching system two batching scale work at same time which is controlled by FDSP developed independently batching program, achieve accurate quick and slow feeding, quick batching and with high accuracy.

Weighing equipment: batching scale PCS15 /PCS10, weighing accuracy: dynamic≤3‰, static≤1‰.

Mixing equipment: mixer SHSJ3, (22KW,1500kg/batch), designed output 24-30t/h/set,  homogeneity CV≤5%.

Granulation process: 

Three set double conditioner pellet mill is used in this process. Two pellet bins are equipped for each pellet mill which is easy to change the formula. After granulation, the pellets enter into the cooler ,bucket elevator and then go to screening by rotary screener. The finished products go to the packing bins, others go back to the pellet mill other received by bags.

Granulation equipment(3sets): SZLH420, 110KW，output 6-8T/H(¢4.0mm grass carp  feed). Cooling equipment(3sets)：SKLB4，volume 4m3 output 6-8T/H/set

Packing process: 

There are 3 packing scale and 12 FP bins in this process.  vibration screener is all equipped before packing scale to screen the powder in final pellets which can improve the feed pellet quality, the design also consider the bulk transportation.

Packing equipment: belt packing scale weighing rage 20-50kg/bag, 6-8bags /min.

Auxiliary process:

Dust collection system can improve the work condition, the oil adding system is usually seen in the mixer adding system which can improve the feed palatability.

The process can be optimized according to different customer needs:

1. Single point dust collection mode is used in the plan which means pulse filter is equipped for every rotary distributor (mesh) and granule cleaner with good effect. Single point dust collection is kind of humanized design of our company, to provide a better working environment, but the cost increases, customers can consider whether it is needed in actual situation;

2. The quantity of bins can be adjusted to achieve the beast use ratio and effectively control the production cost based on factors such as customers' formula, characteristics of raw materials.

3. The crumbler after cooler is optional, if the customer need to produce crumbled fish feed.
