Extrusion Method Double Roller Press Granulating Machine For Indian
Market
Introduction to roller press granulating machine
Our DZJ series roller press granulating machine is a new type of
equipment developed on the basis of the original double rollers
extrusion granulation machine according to the many years of our
production experience. Roller press granulator can be widely
applied to fertilizer processing, feed production and chemical
industry for granulation, production and processing of powder
materials.

Working principle of roller press granulating machine
The belt is driven by an electric motor, and the transmission belt
is transmitted to a pair of two high pressure rollers with sliding
housing through the reducer to do relative work. The two rollers of
the DZJ-I extruder interact with the relative work of the open
gear, and the two rollers of the DZJ-II extruder is directly driven
by two output axes on a special reducer to achieve the purpose of
extrusion molding.
When the raw material is processed, they enter the hopper, and are
extruded and molded through the high-pressure roller body, and then
flow to the broken molding workshop of the lower part of the roller
body after demolishing. The driving force of the crushing molding
is that the chain wheel of the active roller shaft is driven by the
chain to a pair of broken rollers to carry out relative motion, and
the broken roller is sieved in the workroom, and the finished
particles are out of the machine through the screen to the
discharge slot.
Features of roller press granulating machine
1. The roller press granulator is without drying process, room
temperature granulation, a molding, less investment, quick effect,
and good economic returns.
2. Compound fertilizer on roller extruding and granulating machine
power of small reliable operation, no waste discharge, stable
operation, convenient maintenance, process layout is reasonable,
advanced technology, low production cost.
Advantages of roller press granulating machine
1. Environmental friendly. Reliable motor is used, no three wastes
releasing which is environmental protection.
2. Lower energy consumption. There is no drying process. It doesn’t
need oil or gas fired, bringing fertilizer investors’ good economic
returns with low investment.
3. Making raw materials to fertilizer granules at once time. The
roller compactor granulator has higher granulating ratio of over
85%. The granular shape of finished products pressed by double
roller granulator is elliptical.
Applications of roller press granulating machine
The double roller press granulating machine is used in chemical
fertilizer production line & other products production, such as
urea, ammonium nitrate, potassium chloride etc.
