Roller compactor granulator for bio fertilizer manufacturing is suitable for small yield bio fertilizer production and is the choice of most biological fertilizer manufacturers. Generally, the roller extrusion granulator adopts the double roller extrusion granulation method, the raw material source is rich, the feed moisture is between 5%-10%, and the granulation size is between 3mm-10mm. Our company has three types of roller extrusion granulation machine. The price is favorable, for you to choose.

What is the process of roller compactor granulator for bio fertilizer manufacturing ?

The roller compactor granulator is a common bio fertilizer processing equipment. Its working principle mainly includes the following steps:

biofertilizer dry granulation principle

The raw material is first put into the hopper between the rollers.

Under the action of a roller, the raw material is compressed into a sheet. The surface of the roller usually has grooves or patterns that help compress the material into a uniform sheet.

With the rotation of the roller, the sheet is continuously compressed and processed by the cutting or crushing device. These devices, which can be blades, knife wheels or hammerheads, rotate or vibrate to cut or break the sheet into a bio fertilizer granular material.

During the entire process of microorganism fertilizer pellets, the operator can adjust parameters such as the pitch, pressure, and speed of the roller as needed to control the size, shape, and density of the biofertilizer particles.

The processed biological fertilizer granular material is discharged through the discharge port to be collected or further processed.

Through this series of steps, roller compactor granulator can efficiently compress and granulate  raw materials to meet your biological fertilzer production needs.

What are the factors that affect granulation size ?

The final granule size for a roller granulator is typically in the range of 3-10mm. By adjusting roll pressure, roll distance, feed amount and other parameters, you can change the granule size of biofertilizer produced by roll extrusion granulator.

Roll Pressure Regulation

The degree of compaction in the biological granulation process is controlled by adjusting the pressure of the roll. Increasing the roller pressure can increase the density and hardness of the biofertilizer granulation. Reducing the roller pressure will reduce the density and hardness of the microorganism fertilizer granulation.

Roller Spacing Adjustment

Adjusting the distance between rollers can control the thickness and shape of the microbial fertilizer granulation. The smaller the spacing between rollers, the larger the thickness of the granulation. The more regular the shape of the bio fertilizer particles; The larger the roller spacing, the smaller the thickness of the granulation, and the shape of the particles may not be regular enough.

Feed Quantity Adjustment

Controlling the feed quantity can adjust the feed speed and quantity of raw materials, thus affecting the density and quality of microbial fertilizer granulation. Increasing the amount of feed will increase the particle density. Reducing the amount of feed will decrease the biological pellets density.

How much does microbial fertilizer roller compactor granulator cost ?

If your budget is between $2500-3000, you can buy the model SXDG-1T roller granulator. If your budget is $3000-3500, you can buy an SXDG-1.5t counterroll granulator. At the same time, you can also choose to spend $3500-4000 to buy a more efficient granulator.

Of course, if you have more budget and needs, you can buy a roll granulation production line to facilitate mechanized production. Usually small production such as the production of 1-5t/h bio fertilizers per hour, the production line price is $30,000-50000. The production line price of biological fertilizer that produce 6-10t/h per hour is generally $100,000-200,000.

What is the feed moisture content of roller compactor granulator for bio fertilizer manufacturing ?

The feed moisture has an important influence on the operating effect and particle quality of Roller Compactor Granulator. In general, for roller extrusion granulators, the feed moisture of the biofertilizer raw material requirements are usually between 5%-10%. This is because the moderate moisture content helps the bio fertilizer raw material form a good sheet. It facilitates the compaction and granulation process of the roll extruder.

Advoid high moisture:

Excessive moisture content will cause the raw material to become viscous and difficult to compress into thin sheets through the roller extrusion machine. This will affect the formation and quality of biofertilizer particles. At the same time, too high moisture content is also easy to cause the microorganism fertilizer particles to bond together in the subsequent crushing and screening process. This will increase the return rate. In addition, the roller extrusion granulator adopts dry granulation, so it is necessary to prevent the raw material from having too high moisture content.

Low moisture:

On the other hand, if the feed moisture is too low, the raw material is difficult to form a good sheet in the roll extrusion machine. It will also affect the molding effect and quality of the particles. When using roller extrusion granulator granulation, tend to control the moisture content of raw material in a suitable range, to ensure the stable output of microbial fertilizer grain quality.

What is the production line of roller compactor granulator for bio fertilizer manufacturing ?

Roller compactor granulator for bio fertilizer manufacturing is a common equipment in the biological fertilizer granulator production line. But it is also a key granulation equipment for compound fertilizer production line. Due to its compact structure and small footprint, it is suitable for the production of biofertilizers with small yields.

To form a certain capacity of continuous, our company with the corresponding equipment, composition of roll extrusion granulation production line. When setting up a simplified dry roll granulation line, in order to ensure efficient operation in a limited space, you can choose the relevant equipment: loader type feeder, chain crusher, horizontal mixer, rotary screening machine.
