Installation and debugging of roller press granulator


The user has purchased fertilizer production equipment, which must be readjusted after installation is completed in order to operate normally. The following is the installation and debugging method of the roller press granulator.

1. Installation of roller press granulator
After the roller extrusion granulator arrives at the plant, it takes the granulator as the main machine, which depends on the number of units, and is installed in coordination with the NPK fertilizer production line flow chart to find out the elevation and horizontal placement. The machine frame has corner holes, which can be installed on the concrete (the fixed vibration momentum is not large and does not need a very solid concrete foundation).

2. Commissioning of roller press granulator
Our fertilizer granulator has been debugged before leaving the factory, but it still needs to be debugged in actual use.

1). Adjustment of the pressure roller gap:
In the granulator production, sometimes it is necessary to increase the output or increase the bite angle. At this time, the distance between the two shafts can be increased. The distance between the active shaft roller and the passive shaft can be increased. The steps are as follows: stop, unload Go to the frame above the two-sided bearing pedestal, and adjust the adjustment plate between the two-sided bearing pedestals to the required thickness. The rollers should not collide between the two rollers, and it should be kept between 0.3-1mm.

2). Alignment adjustment of the ball and socket of the doublle roller press granulator
The ball and socket are made up of the recesses on the surface of the main and driven rollers, so there are problems of axial alignment and circumferential alignment

A. The axial alignment 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.

B. Circumferential alignment: the steps of circumferential alignment are as follows: loosen the 6 connecting bolts between the passive gear and the adjusting sleeve, so that the adjusting sleeve and the passive gear are slightly separated. 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 it 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.
