GZL Series Dry Roller Pressing Granulator

GZL Series Dry Roller Pressing Granulator


The set adopt the technology of dry roll-extruding, the powder content moisture (<10%) is compressed to sheet, then through the technique of fragmentized, coordinated, sieving, the sheet material become lump, and reach the operating request.
The set grain pressure from the outside and force material pass through two counterrotating rollers, when rolling the actual density of material increase 1.5-3 times, thus reach the require of strength.


All kinds of dry starch are supplied from the top of the equipment, the materials enters into two parallel rollers, after degassing and sprial pressing. The material is forced into the two rollers and is compressed by the two counterrotating rollers, the surface tension and gravity of material make it deviate from the slot naturely after passing through compression area, the strip material which enters into pulverizer is crashed by rotary kinfe, the rotating knife of coordinated machine make material enter into vibrating sieve. After sieving, qualified products are sent into material storehouse through conveyer, unqualified products are sent into material storehouse and will be rolled secondly through conveyer, the size of pushing strength can be adjusted by the hydraulic pressure cylinder according to the need.
Through changing the form of slot on the roller can get the slice, strip, flat, material.


Material is compressed by force, doesn’t add any humectant, the purity of the products gets the assurance.
Dry powder is granulated directly, needn’t dry process, more favorable to the connection and transformation of existing process.
The strength of the granule is high, the enhance of bulk specific is obvious than the other model of granuator, especially suit for the product that need increase the bulk specific gravity.
It can control environmental polltion, reduce the powder wasting and the cost of packet, increase the capacity of transport.
Structure is compact, maintain is convenient, operation is easy, technological process is shot, energy and trouble is low, efficiciency is high, the suit range is wide and pressure of the roller can be adjusted freely according to the need.
The device of feeding adopt frequency conversion and infinitely variable adjustment, degree of automation is high, can realize multimachine is controlled by one person, labour intensity is low and can running continiously.
The part of main transmission adopts the high quality alloy material, stainless steel material, titanium products, chrome and other surface alloy, it improved abrasion rsistant, corrosion proof, high temperature resistant and pressure ability greatly, make the machine has long life.

Flow Chart
Material enters into bucket elevator through sprial conveyer from feeding hole, then enters into vibrational storehouse through bucket elevator. The material through quantitative filling machine is sent to sprial feeder, after precompression the material is compressed by counterrotating rollers, the strength of pressure transfer to the material by the thrust of oil tank, the sheet material sent into pulverizer after deviating from the slot natureally, material is crashed to different size and then is coordinated, the coordinated material is extruded into vibrating sieve through the meshes of sieve, qualified products send to finished parts storehouse by bucket elevator after sieving, unqualified products return to the material storehouse. Thus finishing the closed circulation after being compressed secondly
