Fertilizer Dryer Installation Tips

In the production line of organic fertilizer and NPK fertilizer, drum dryer is an indispensable equipment for drying treatment. When installing the dryer, the height of the near fire end is higher than that of the far fire end, which is a wrong method. The device will speed up the movement of fertilizer particles and shorten the fixed time of materials in the rotary drum of dryer. 

In this case, the lifting plate in the oil cylinder cannot be lifted normally, and the drying effect is not very good. At the same time, it will cause unnecessary trouble to the installation and operation of fertilizer equipment.

Drum dryer in chemical fertilizer production line

The dryer is usually a downstream dryer. If the steam can not be discharged in time during the drying process, the steam in the drum will run for too long, and even lead to the material fusing with moisture again. As an organic fertilizer manufacturing machine, in the installation process, a set of anti-skid supporting wheel fixed belt is used to switch on and off, so as to prevent the drying equipment from slipping during operation.

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.
