GZL Series Dry Roller Pressing Granulator

Product Overview:
GZL series of dry granulating machine is the roller pressure by dry extrusion technology, the water content of <10% of the powder compressed into tablets, through the broken Whole, the screening process so that the bulk of the film material into line with the requirements of the use of granular materials.
dry granulation roller pressure on the external pressure is the main way through two materials mandatory rotation of roller round of negative space, compressed into tablets. Roll pressure in the process, the actual density of materials to increase 1.5-3 times to meet certain requirements of the force.

Features:
materials are mandatory compression molding machinery pressure, do not add any wetting agent, the purity of the product is assured.
powder made material directly, without follow-up the drying process will be more conducive to the convergence of existing production processes and transformation.
high intensity particle accumulation other than increasing share of granulation method is more significant. Especially for the increase in the proportion of product accumulation of occasions.
can control environmental pollution, reduce waste and powder packaging costs, improve product transport capacity.
compact structure, easy maintenance, simple operation, the process short, low energy consumption, high efficiency and low failure rate, suitable for a wide range of raw materials, pressure roller to adjustment based on different materials.
feed and feed device using frequency stepless adjustment control, a high degree of automation, a person can achieve multi-machine control, low labour intensity, and the long-term continuous operation, and other features.
main transmission quality components are used alloy, stainless steel materials, Titanium, chromium and other surface alloy production, greatly improving the wear resistance, corrosion resistance, high temperature and pressure capabilities, the aircraft has a longer life.
Principle:
various powder materials from the top by adding equipment, the degassing, spiral surcharging equal access to the two rollers, roller relative rotation, and materials are forced into between two rollers, roll materials will bite into the roll gap compression , and materials through the compression zone, materials, surface tension and gravity make it naturally emerge. Prolapse refers to the strip into the mass of the rotating nibs Pai broken knife was broken materials enter through the rolling machine knife Whole row of the particle and powder materials into the rotation vibration sieve screen. Qualified for and was sent by conveyor products warehouse. Powdered materials through the sieve again be returned to the conveyor secondary raw materials warehouse roller pressure, squeezing pressure on the size of operation according to the needs of granulation from the hydraulic pressure regulation.
by changing the roll surface grooving form can be patchy, strip, Chen Shui-bian spherical materials.

Process:
I passed by feeding raw materials into the screw conveyor bucket hoist by bucket elevator powder materials will be sent vibrating raw materials warehouse, through quantitative materials will feed into the machine screw Feeder frequency of the material pre - compression, the pre-compressed material being pressed into two relative of the two pairs of rotation among compaction roller pressure, pressure through the strength of the thrust from the fuel tank pressure roller to transfer materials, the film was compacted bar Material from automatic slot into the crusher, will be broken into its uneven size of the particles and then go to Whole machine repaired. Are trimmed with the particles through the mesh sieve plate was squeezed out into the screening machine, finished particles through the screen and entered bucket elevator and was sent to warehouse products. Screener down through the powder returned to the screw conveyor of raw materials warehouse, which completed a compaction again closed cycle.
