Detailed description

Overview:
           GZL series of dry roll granulator machine is used for dry extrusion technology, the water content of <5% of the powder material is compressed into a group, and then crushed, whole, screening process, clumps like material into compliance with the requirements of granular materials. 
         Dry rolling granulation mainly by way of external pressure, so that the material is forced through two counter-rotating roller gap, compressed into groups. In the rolling process, the performance density of the material can be increased 1.5-3 times, so as to achieve a certain strength requirements.   
Principle:
         all kinds of dry powder material from the top of the equipment, degassed spiral pre-press to enter two equal roll, roll relative rotation, the material is forced into between two rollers, grooved rollers the material is forced to bite into the nip compression the material through the compression zone, the surface tension and gravity of material make it naturally emerge. After prolapse refers to the strip clumps into the nibs machine row by a rotating knife broken, the broken material into the whole machine exhaust particles and some powdered materials into vibration sieve were sieved through a rolling knife. Qualified products warehouse is fed by conveyor. By powder sieve material is fed back through the conveyor for secondary raw materials warehouse again rolling, extrusion pressure can be regulated by a hydraulic cylinder pressure according to different requirements.   
          By changing the slotted form of the roll surface can be obtained sheet, strip, flat spherical materials.   
Process:
         raw materials from feeding through the mouth into the screw conveyor bucket elevator raw material powder into a vibrating raw materials warehouse, through quantitative feeder material into inverter screw feeder, the material is pre-compressed by the pre-compression the material is pressed into two opposing branches turn two pairs of intermediate roll compaction, the compaction force by the thrust of the cylinder by the pressure roller to transfer the material, the material is compacted flake off automatically slot into the crusher, it is broken into uneven size of the granules, then into the granulator for trimming. Trimmed granules through the sieve with a mesh is squeezed out into the screening machine, the finished granules by sieving into the bucket elevator is fed into the finished product warehouse. Powder sieving down through the screw conveyor to return the raw material warehouse, re-compacting thereby completing a closed cycle.   
Features:
         Materials by mechanical pressure to force compression molding, does not add any humectant, the purity of the product is guaranteed. Dry powder is granulated directly, need not dry process, more conducive to the convergence of existing production processes and transformation.   
         High particle strength, increasing the bulk specific gravity than other granulation methods are more significant. Especially suitable for increasing the bulk specific gravity of the occasion. You can control environmental pollution, reduce waste powder and packaging costs, improve product transport capacity.   
         Compact structure, easy maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate, adapt to a wide range of raw materials, roll pressure can be adjusted depending on the material. The device of feeding adopt stepless height adjustment and adjustment control, the degree of electromagnetic frequency stepless automation can achieve a multi-machine control, low labor intensity.   
         The main transmission parts are made of high quality alloy material, stainless steel, titanium, chromium and other surface alloy production, greatly improving the wear resistance, corrosion resistance, high temperature and pressure capabilities of the machine with a longer life.
