Product Description

Advanced Technology Double Roller Press Briquetting With Compact Structure

Product description:


Product Application
     Dry granulation can be conducted under this process: the powder is squeezed between two counter-rotating rollers to produce a continuous sheet or ribbon of materials.
     DH series dry roll press granulator adopts dry rolling technology to compress the powdery materials with moisture content ≤1% 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:




1). Use belt scales to weigh each raw material according to formula.---Batching system
2). Use mixer to the raw material for more uniform feeding.---Mixer
3). Use bucket elevator lift the material up to the silo.----Bucket elevator and Silo
4). The DH SERIES COMPACTOR compress the raw material by double rollers, it mainly depending on the mechanical pressure to compress the dry powder, so the hardness of granular is very high.---------DH SERIES compactor (including three parts: dosage screw feeder, forced feeder and flaking machine.)
5). Then we get the bar shape products.
6). So we need a crusher to crush the bar shape products into 2-4mm irregular granules.----Crusher (you can decide the size of granules, we will design the size of crusher mesh.)
7). 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. You will get the qualified 2-4mm irregular shape granules successfully.--------Rotary Screen
8). Next we use the second time rotary screen, the purpose is we want to get better result of irregular 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.)
9).After second sieve, the granule enter into the rotary drum for coating.You can spray some liquid or powder on the surface of the particles to avoid clumping.-------Coating machine
9). The last step is packaging machine. This machine will help you pack the final granular into bags. ---You can choose 25-50kg/bag Packaging Machine or TON-package machine(800-1000kg/bag)
10). Workshop dusts mainly come from the crusher, screening and discharging port of bucket elevator, in order to effectively remove the dust, this process uses two stages of dust removal. A cyclone dust collector is used to remove the larger particle dust, and then the bag dust filter is used to remove the residual dust. The dust from the dust collector will return to the granulation process by scraper conveyor.------ Dust collecting process.

Peripheral equipment:


Peripheral equipments for granulation line
  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.
Main 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) A wide range of raw materials can be used, granular strength can be freely adjusted according to different materials.
6) Compact structure, easy maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate.
7) Control environmental pollution, reduce waste and powder packaging costs, and improve product transport capacity.
8) 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.
