Installation and debugging of the roller extrusion granulator

The organic fertilizer double-roll extrusion granulator is a new type of granulator equipment in the organic fertilizer production industry, also known as dry powder granulator or organic fertilizer dry granulator. So how to install and debug the newly purchased organic fertilizer double-roller extrusion granulator?-Let’s take a look.

The reason why it is called the organic fertilizer double-roller extrusion granulator is because the equipment can directly compress and granulate the fermented powdered organic fertilizer during the granulation process. It is formed once and can be directly packaged by the organic fertilizer packaging machine. product. It eliminates the need for drying and cooling after granulation in the traditional organic fertilizer production process.

Working principle: The organic fertilizer double-roller extrusion granulator mainly relies on external pressure to force the material to pass through the gap between two oppositely rotating rollers, and is forced to compress into pieces. During the rolling process, the actual density of the material can be Increase by 1.5~3 times, so as to meet the requirement of certain particle strength.

Installation and commissioning of organic fertilizer counter-roller extrusion granulator:


After the newly-purchased organic fertilizer double-roll extrusion granulator arrives at the factory, the granulator is used as the main machine. It depends on the number of units and is installed in conjunction with the process flow chart. Find out the elevation and horizontal placement. This rack has a corner Hole, can be installed on concrete (the amount of solid vibration is not large, and the concrete foundation is not required).

Equipment installation and commissioning of organic fertilizer dry method roll granulator:


(1) Axial alignment: It has been adjusted during installation. Generally speaking, the possibility of adjustment is unlikely. When adjustment is required, tighten or loosen the glands on both sides of the passive bearing seat, thereby pushing the displacement of the eccentric sleeve and the driving shaft The roller corresponds.

(2) Press roll gap adjustment: Sometimes it is necessary to increase the output or increase the bite angle during production. At this time, the distance between the two press shafts can be increased, and the distance between the driving shaft roller and the driven shaft can be increased. The steps As follows: Stop the machine, remove the upper frame of the two bearing housings, adjust the adjustment plate between the two bearing housings to the required thickness. The two rollers cannot collide with each other, and the minimum should be kept between 0.3-1mm. .

(3) Ball socket adjustment: The ball socket of the organic fertilizer dry roll granulator is formed by the concave socket on the main roller surface, so there are problems of axial alignment and circumferential alignment. ;

(4) Axial alignment steps: loosen the 6 connecting bolts of the driven gear and the adjusting sleeve, so that the adjusting sleeve and the driven gear are slightly disengaged, because the design has considered a ball and socket adjustment amount, and is equipped with two There are two adjusting bolts, so it can be adjusted regardless of the misalignment. Because the ball socket is too small, the carton board is placed between the two sticks during adjustment. After rolling, it can be seen whether the adjustment has achieved the goal. After adjustment, 8 connecting bolts can be tightened.
