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
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.
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
