Customer Highly Praised Roller Press Granulator Machine Used For Dry Chemical Fertilizer

Introduction to roller press granulator machine

Double roller granulator is a kind of fertilizer press machine, which is used for making fertilizer pellets. Its pellets are oval shape. It can work under normal temperature, but yields high granulation ratio.

Specifications of roller press granulating machine

Working principle of roller press granulating machine

There are mainly five steps turning materials into granules with this double roller press granulator machine.

1. Firstly, you need put the mixed fertilizer materials on the belt conveyor, then the powdery raw material will enter the double roller press granulator.

2. The material is forced between the two rollers below for extrusion, and the two rollers rotate relative to each other.

3. Under the strong extrusion pressure, the delivered materials become a cake shape with a stick mold, and the cake shape bar enters the crushing workshop.

4. The crushed materials are broken by the broken axis, and are screened through the screen below the crushing chamber.

5. Qualified particles are sent to the outside through the air. And the sifted powder material will be sent back to the raw material warehouse for the second roll.

Features of roller press granulating machine

The structure of the machine adopts granulation, molding and screening as one, which has the advantages of good looking, simple operation and low energy consumption.

The main parts, such as rollers, are made of a new type of metal with corrosion resistance, wear resistance and impact resistance of roller press granulator. The DZJ-II machine not only has the above characteristics, but also has the updated frame part has also been upgraded. The bearing frame is selected as the whole component with high quality anti-corrosion casting. With more stable performance, it can greatly improve the operation life of the rolling bearing and shaft.

For the transmission part, we use the dual input transfer mode, which not only improves the input power ratio, but also ensures the lubrication and sealing performance of the transmission gear. The machine has the advantages of compact structure, good stability, good sealing, low noise, convenient operation and easy maintenance. After the new machine launched, it was deeply liked by masses of users.

Advantages of roller press granulating machine

1. Wide application scope. At present, there are 20 kinds of raw materials being applied in this extrusion granulation, such as urea, ammonium nitrate, potassium chloride, bentonite. In addition, it can replace the product formula flexibly in a short time by adopting extrusion granulation technology. A set of device can produce over 30 product formulas.

2. 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.

3. Environmental friendly. Reliable motor is used, no three wastes releasing which is environmental protection.

4. 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.

Application of roller press granulating machine

Double roller press granulator machine can be widely used in many businesses. It can granulate pellets with a number of different kinds of raw materials. Here are some of the applications for you to refer to.

1. Compound fertilizer granulation.

2. Solid chemicals granulation.

3. Pharmaceutical granulation.
