Double Roller Granulator Installation Guides

 Guide for installation and commissioning of organic fertilizer double roller granulator

1. Installation:

After arriving at the plant, the drum extrusion organic fertilizer granulator will be installed with granulator as the main machine. According to the number of units and the organic fertilizer manufacturing process flow chart, the elevation and horizontal position are found. There are corner holes in the frame, which can be installed on the concrete (the solid vibration is not large, and a very solid concrete foundation is not required).

2. Debugging:

Our double roller granulator has been debugged before delivery, but it still needs to be adjusted after trial.

(1) Adjust the press roll clearance

In the production process, it is sometimes necessary to increase data output or data biting angle. In this case, the distance between the two compression shafts can be increased and the clearance between the drive shaft roller and the drive shaft can be increased.

The steps are as follows: stop the roller granulator, remove the frame above the two bearing blocks, adjust the adjusting plate between the two bearing blocks to the required thickness, prevent the roller collision between the two rollers, and maintain a minimum clearance of 0.3-1 mm. Go here for details.

(2) Ball and socket alignment adjustment

The ball and socket are formed by pits on the surface of the main roller, so there are problems of axial alignment and circumferential alignment.

Axial alignment has been adjusted during installation. Generally speaking, the possibility of adjustment is very small. When adjustment is required, tighten or loosen the seal rings on both sides of the passive bearing housing to push the displacement of the eccentric sleeve corresponding to the roller of the drive shaft.

Align the circumference. The steps of circumferential alignment are as follows: loosen the 6 connecting bolts of the drive gear and the adjusting sleeve, so that the adjusting sleeve and the driving gear are slightly separated. Since a spherical and socket adjustment is considered in the design and two adjusting bolts are provided, the deviation can be adjusted no matter the deviation is too large. As the ball sleeve of the double roller granulator is too small, the paperboard is placed between the two rollers during the adjustment process. After scrolling, you can see whether the adjustment has achieved the goal. After alignment, tighten the 8 connecting bolts.

Extrusion VS Rotary Granulation

In the process of chemical fertilizer manufacturing, various powders, small pieces, aqueous solutions or melted raw materials are made into particles with necessary appearance and compressive strength. According to the chemical properties of raw materials, efforts should be made to reduce dust pollution, improve performance and improve production and processing effect.

According to the fertilizer manufacturing process in granulation, according to the different aggregation methods of the initial ultrafine particles, the processing technology of the granulator can be divided into extrusion granulation, rolling granulation, spray granulation, hot melt making and fluidized granulation. Pressure granulation and rolling granulation are two common methods of fertilizer production. What is the difference between the two fertilizer production methods?

The pressure granulation method limits the powder form in the closed internal space, releases the external force, and improves the compactness of the material. Pressure granulation can be divided into two types, one is compression molding granulation, in which raw materials are placed in a closed mold cavity and extruded into a cylindrical belt according to repeated movement. The other is double roller granulation, which is commonly used in double roller granulator. In the process of sand pressing, raw materials are crushed, granulated and screened. With the popularization of rollers, materials are formed.

Rolling granulation is to infiltrate the binder into the fine powder on the solid disk to produce micronuclei. The rearranged particles are rolled many times and then become spherical particles of a given size. The equipment of roller granulator usually includes disc type fertilizer granulator and rotary drum granulator.

Granulator is an important part of fertilizer processing technology. In order to save costs, some enterprises usually only choose the appropriate granulation equipment for production. Therefore, granulator is not only used in industrial field, but also used in chemical industry and agriculture. According to the market application, granulators include fertilizer granulator, sawdust granulator, plastic granulator, pulverized coal granulator, etc. Understanding the different granulation methods in fertilizer production is helpful to purchase appropriate granulation equipment.
