Roller extrusion granulator installation and testing


1. Installation: after roller extrusion granulator delivered to user factory, the granulator is the main machine, according to machine group to design, match with granulating process flow diagram to install, find standard height and horizontal place, main machine frame with foot hole, can be installed on the concrete, if the machine working without too much vibration, no need fixed on the concrete foundation.

2. Testing: before roller granulating plant out of seller factory has already being tested, but still should be testing during the machine working process:
a. Roller gap adjust: during roller granulator china supplier working process, sometimes, you should increase the production capacity or increase meshing dip, at this time, you should increase the gap between two roller, the meaning is increase driving shaft roller and driven shaft roller gap. The steps: stop the machine working, disassemble the frame which on the bearing seat top position, adjust the bearing seat thickness to required gap, make sure the two roller can't impact each other, min thickness should keep at the range of 0.3-1mm.
b. Double roller granulator Ball nest position adjust: ball nest meshing at the opposite direction on drive and driven roller skin, thus exist axial adjust the position and circumferential adjust the position problem:

i. When installation fertilizer roller granulating equipment axial adjust the position has already finished, it's unnecessary to adjust, when adjust, tighten or loosen press cover on driven bearing seat, thus pushing eccentric sleeve displacement corresponding to drive shaft roller.
ii. circumferential adjust the position steps: loosen driven gear and on the adjust sleeve 6 connection bolts, making adjust sleeve and driven gear slight disengagement, as when roller compound fertilizer granulator design, we have already considered a ball nest adjust amount and match with two adjust bolts, so, whatever dislocation can be adjusted. As ball nest is too small, when adjust, you should put carton board between the two rollers, after pressed, you can confirm whether the adjustment achieved the purpose or not. After that, tighten the roller granulator sold to india eight connection bolts.
