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.

• Mixing: We use mixer to mix the raw material
• Lifting: We use bucket elevator to lift the material up to the silo
• Compaction: The compactor compresses the raw material by double rollers (including dosage screw feeder, forced feeder and flaking machine)
• Product Formation: Then we get the oval ball/oblate ball/square shape products
• Primary Screening: We use rotary screen to sieve the final products - unqualified products are recycled for next granulation process
• Secondary Screening: Second time rotary screen for better result of regular shape granules (optional process)
• Packaging: Automatic packaging machine packs the final granular into bags

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.

• Granular strength can be adjusted by adjusting the pressure of roller
• Cycle operations to achieve continuous production with high yield of finished products
• Materials are force to compress molding by mechanical pressure, without any additives
• Dry powders are granulated directly without follow-up drying process
• Granular strength is high with significant improvement of bulk density
• Wide range of raw materials can be used with adjustable granular strength
• 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
• Feeding device adopts frequency adjustment control with high automation
