INSTALLATION REMIDERS
Proper operation of equipment is largely dependent upon proper installation procedures. Pay particular attention to the
following installation procedures:
1)
Foundations, pits (if used) and anchor bolt LAYOUTS SHOULD BE CHECKED WITH CERTIFIED FOUNDATION
DRAWINGS before proceeding with the actual installation.
2)
REMOVE ALL DEBRIS from pits, foundations and general installation area.
3)
Install lower abrasive cycling parts in pit first, if used - these may include hoppers, shaker conveyors, worm screws,
etc. Level and shim components if necessary.
4)
PLACE FELT OR TAR PAPER STRIP AND MASTIC CEMENT BETWEEN EDGES OF ALL PARTS THAT ARE TO
BE BOLTED TOGETHER. Tightly sealed joints are important to proper installation. Cement and felt or tar paper
strip are included with shipment of all equipment.
5)
Erect main cabinet section, drifting or reaming matching bolt holes as may be necessary. If main cabinet section is
composed of separate wall and roof panels, use mastic cement and felt or tar paper strip between all joints.
6)
LEVEL CABINET AND SHIM ACCORDINGLY.
7)
When erecting the abrasive elevator, give particular attention to the following:
a) Make certain that all connecting joints are properly sealed with mastic cement and felt or tar paper.
b) PLUMB ELEVATOR CASING, shim if necessary.
c) Drop the head pulley to the lowest point of the elevator belt takeup device. Install rubber elevator belt making
certain that buckets are headed toward the proper discharge direction. If bucket belt needs to be shortened,
MAKE A STRAIGHT BELT CUT AND SPLICE BELT SQUARELY.
d) Tighten belt by raising the head pulley. Belt will stretch excessively for a period of approximately two weeks.
RECHECK BELT TENSION OF A NEW BELT EVERY COUPLE OF DAYS AND RETIGHTEN BY RAISING
TAKEUP. Check alinement of belt, DO NOT ALLOW BELT TO RUB AGAINST THE CASING . Belt should ride
on center of crowned head pulley. Belt will invariably ride toward low side of pulley, raise that side of the pulley
in small increments to center the belt.
