Product Description

DH Series Dry Roll Press Granulator

       Our company  offers a wide range of machine sizes for high pressure granulating, which covers nearly all requirements of the clients.If your production is low,you can choose small type machine, if you have high production, you can choose one or more sets of machines according to your requirements.And certainly the process of granulating is dry.

Working principle  

         Raw materials are sent into hopper by quantitative feeder, compactors use the pair of roller with the hole roll, leaving certain gap and rotation with the same speed reversely. Shaft holders of one group of rolls are fixed, and the other one of group can slide to help the hydraulic cylinder press the rolls for abutting closely against each other. Many arc grooves with the same shape and size are arrayed regularly on the roll surface. In accordance with different compressing ratios of target materials, the wave though of arc groove of one roll shall be directed at that of one roll. When two rolls parallel each other horizontally, powder grained materials are, continuously and evenly fed in the gap between two rolls by means of their gravities and through a forced charger from above of two rolls. After entering the nip area, the materials are gradually nipped by the rolls. With continuous rotation of the rolls, the space that the materials occupy reduces gradually and is compressed step by step and reaches the maximum shaping pressure. And then, as the pressure reduces gradually later, pressed blocks drop off the arc grooves of the rolls for recovered elasticity and gravity of the flaking machine and enter a crushing device for crushing and then enter a sieving device for sieving. At last, grained products are obtained. The powder materials and large particles which are substandard will return to bucket elevator and enter into the next process with new products.

Features

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

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

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

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

4. 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.

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, low labor intensity and long term continuous operation,etc.

9. Major transmission components use high quality alloy material. Stainless steel, titanium, chromium and other surface alloys which greatly improved wear resistance, corrosion resistance, high temperature and pressure capabilities, so that this machine has one long service life.

Flow chart-Dry Roll Press Granulator

1. Single set of processes

• This process is DH650 and the following models of the conventional process
• 

      The process is the basis process for the design of the company's dry granulation, In the process raw material will be lifted by bucket elevator to prepare granulation bin, and then into the granulator, material roll forming directly into the crushing system, after crusher broken into screen, The particles divided into qualified granules and unqualified particles by screen net of screen, qualified particles can be directly into the next process, or direct packaging, and unqualified particles will be returned to the raw material bucket elevator, and then re granulation process.

• This process is DH850 and the above model of conventional process

2.Multiple sets of processes

       This process is the process of multiple sets of equipment, can be designed according to the site and customer demand, single bucket elevator can be used for loading and granulating, or lifting to the feed hopper, use hopper to feed. After the process of crushing and screening, the materials are crushed and screened.

      "Mixing - granulation - pre crushing - concentrated crushing - Screening - polishing - second screen - packaging", After the screening ,fine powder material to return to the raw material mixing again into the granulation system to form a granulation cycle, improve the granulation efficiency of the granulation process.

      According to the demand, the granulation of the preceding paragraph can be added batching or drying system,in this process, due to the larger strip produced by the tablet, the lower end of the granulation machine is equipped with a pre crushing machine, pre crushing and then concentrated crushing. The qualified material produced by the screening enters into the next polishing, second screening and the packing process, and the screening out of the unqualified large particles are returned to the impact crusher for re broken, the unqualified fine powder is returned to the raw material place to carry on the re granulation.
