Granulator Machine

详情

The DH series Granulator also called pelletizer, Gypsum briquetting machine, Briquetting machine, carbon black granulator, graphite granulator machine, gypsum pelletizer.
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.

Working principle:
DH series dry roll press granulator machine 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 pelletizer 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.

◆Without any additives, dry powders are granulated directly.

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

◆Cycle operations to achieve continuous production.

◆High yield of finished products.

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

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

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

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

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

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

◆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.

◆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.
