Chemical npk Fertilizer bentonite granules production line

Product description

The importance of powder granulating technology as one of the most important branches of powder particles processing treatment is increasingly clear with the demand of environment protection and improvement of automation of the production process. “Powder products will become granules” has become the necessary trend of powder-after-processing technology in the world.

DH series dry roll press granulator adopts dry rolling technology to compress the powdery materials with moisture content ≤ 5% into pieces or tablets, then going through the processes of breaking into granules and screening to make the lump materials into granules that meet the requirements of application. Dry roll press granulator mainly depends on the manner of external pressure to force the material going through the gap between two relatively turning rollers to compress into laminar particles. During course of roller pressing, the real density of materials can increase 1.5~3 times thus reaching certain demands of granular strength.

Working principle

* We use mixer mix the raw material.---Mixer
* We use bucket elevator lift the material up to the silo.----Bucket elevator and Silo
* The COMPACTOR compress the raw material by double rollers,the roller shape is oval ball, oblate ball ,square granule----compactor (including three parts: dosage screw feeder, forced feeder and flaking machine.)
* Then we get the oval ball/oblate ball/ square shape products.
* Finally, we will use rotary screen to sieve the final products, the unqualified products, such as dust, big granular and very small granular will be recycled for the next time granulation process. --------Rotary Screen
* Next we use the second time rotary screen, the purpose is we want to get better result of regular shape granules after second time screening, the appearance of irregular shape granular will looks more beautiful. -------Second Time Rotary Screen (if you don’t need this, you can delete this process.)
* The last step is automatic packaging machine. This machine will help you pack the final granular into bags. ----Automatic Packaging Machine

Granulator supporting equipment

In addition to the pellet machine,we can also provide the whole supporting equipment of granulating process to help you finish the granulating much better.
Such as the mixer,feeding machine,the crush machine,the screening machine,drying/cooling machine,conveyor and so on.

Features

1) Granular strength can be adjusted by adjusting the pressure of roller, control strength of final products.

2) Cycle operations to achieve continuous production. High yield of finished products.

3) Materials are force to compress molding by mechanical pressure, without any additives, the product’s purity is guaranteed.

4) Dry powders are granulated directly without follow-up drying process, the existing production process is easy to convergence & transformation.

5) Granular strength is high, compared with other granulating methods, the improvement sof bulk density are significant,especially for the occasion where increase the proportion of product accumulation.

6) A wide range of raw materials can be used, granular strength can be freely adjusted according to different materials.

7) Compact structure, easy maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate.

8) Control environmental pollution, reduce waste and powder packaging costs, and improve product transport capacity.

9) Feeding device adopts frequency adjustment control, high automation ,one can control multi-machine, has the features of low labor intensity and long term continuous operation,etc.
