Installation and commissioning of dry roll granulator for organic fertilizer

November 11, 2019 by zhengtianci  

In the organic fertilizer production line, the double roll extrusion granulator can directly compress and granulate the fermented powdered organic fertilizer, and directly encapsulate the product through the organic fertilizer packaging machine. The fertilizer equipment avoids the process of drying and cooling after granulation in the traditional organic fertilizer production process.

Installation and commissioning of dry roll granulator for organic fertilizer:

1. Installation:

After the newly purchased organic fertilizer dry rolling granulator arrives at the plant, the granulator is taken as the main machine, which depends on the number of units, and is installed in coordination with the process flow chart to find out the elevation and horizontal placement. The machine frame has corner holes, which can be installed on the concrete.

2. Commissioning:

(1) axial alignment: it has been adjusted during installation, generally speaking, it is unlikely to be adjusted. When adjustment is needed, tighten or loosen the gland on both sides of the passive bearing seat, so as to push the displacement of the eccentric sleeve corresponding to the active shaft roller.

(2) adjustment of pressing roller gap: sometimes it is necessary to increase the output or the angle of bite in production. At this time, the gap between the two pressing shafts can be increased. The gap between the active shaft roller and the passive shaft can be increased. The steps are as follows: stop the machine, remove the upper frame of the two bearing pedestals, and adjust the adjustment plate between the two bearing pedestals to the required thickness. The two rollers cannot collide with each other, and the minimum should be kept Between 0.3-1MM.

(3) alignment adjustment of the ball and socket: the ball and socket of the organic fertilizer dry rolling granulator are made up of the recesses on the main and driven roller surfaces, so there are problems of axial alignment and circumferential alignment;

(4) axial alignment steps: loosen the 6 connecting bolts between the driven gear and the adjusting sleeve to slightly separate the adjusting sleeve and the driven gear. Since a ball socket adjustment amount has been considered in the design and two adjusting bolts are equipped, the dislocation can be adjusted no matter how much the dislocation is. Because the ball socket is too small, the carton board is placed between the two rollers during adjustment. After rolling, it can be seen whether the adjustment reaches the purpose. After alignment, tighten 8 connecting bolts.
