Product overview：
Mixer GZL series dry roller granulator is using dry extrusion technology, the water content < 10% of the powder is compressed and then after crushing, whole grains, screening process, make piece of block material conform to the requirements of the use of granular materials.
Mixer is mainly dry roller press granulation by external pressure mode, make the material forced by two opposite rotating roller clearance, compression. In the rolling process, the actual material density can increase 1.5 3 times, so as to achieve a certain force requirements.

Product features：
Materials by mechanical pressure forced compression molding, does not add any wetting agents, product purity guaranteed.
Dry powder directly the deflecting, without further drying process, is more advantageous to cohesion and transformation of the existing production process.
Granular intensity is high, the improvement of the mass density than other method of granulation. Especially suitable for increasing the mass density of the product.
Mixer can control environmental pollution, reduce waste powder and packaging costs, improve product transport capacity.
Mixer compact structure, convenient maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate, suitable for wide range of raw materials, roller pressure can be adjusted freely according to different materials.
Mixer feeding and the feeding device is controlled by frequency conversion stepless adjustment, high automation, which can be controlled more than one machine, low labor intensity, and can long-term continuous operation, etc.
Mixer main transmission parts adopt high quality alloy, stainless steel, titanium, chrome and other surface alloy production, greatly improving the wear resistance, corrosion resistance, resistance to high temperature and pressure ability, make the machine has long service life.

  The working principle of：
Pieces from joining top equipment, all kinds of powder material by the degassing, screw preloading into two equal roll, roll the relative rotation, the material being forced into between two rollers, roll materials will bite into the roll gap can be compressed and material through the compression zone, the material of surface tension and gravity to emerge naturally. Emergence refers to strip after the mass into the broken machine by rotating knife broken, was broken material into the machine through rolling blade row make particles and part of the powder material into the vibration screen for screening. Products through the conveyor is fed into the finished product warehouse. Powder undersize material through the conveyor was again returned to the raw material warehouse second rolling, the size of the extrusion pressure according to the need of granulation operation by the hydraulic oil cylinder pressure.
By changing the roll surface slot form, sheet, strip, flat ball materials can be obtained.

The process flow：
Raw material of feeding mouth through screw conveyor into the bucket elevator, the bucket elevator powder materials will be sent to vibrating raw materials warehouse, by quantitative feeder will be the material into the variable-frequency spiral feeder, pre compression was carried out on the material, the material in the process of the compression by the two relative rotation between two pairs of roller compaction, its compressive strength is through the oil cylinder thrust by roller is transmitted to the material, the compaction flake material automatic groove into the crusher, the crushing into uneven size of particles, and then into the whole machine for renovation. Be trimmed particles through mesh sieve plate squeezed out into extension, finished product after particles through the sieve into the bucket elevator is fed into the finished product warehouse. Fine powder sieving down through screw conveyor return raw materials warehouse, compaction resulting a closed loop again.
