Chapter 3: Installation
3-1 Uncrating the Equipment
The complete granulator, including accessory and auxiliary equipment, is packed in a special
wooden case for shipment. Refer to the Appendix for detailed dimensional data and pertinent
weights.
Prepare in advance the site you have selected for installation of the granulator. Be certain
that the area to be occupied by the machine is clean, level, and free of obstructions. The
machine should be set on a concrete floor, and care must be taken when moving the machine
across a hollow timber floor, so that the point loading of the casters does not cause damage.
The site you have selected must have a floor rating to adequately support the weight of the
machine. If necessary, use steel shims to level the machine.
Locate the machine so that access is given to electrical components, screen, and hopper.
Maintenance personnel should have unobstructed access to the units on which they will be
working.
To avoid squeezing people working near a machine, there should be adequate clearance
maintained between machines, walls, or partitions. Hinged doors and covers should have full
swing. Restrictions may force work in cramped quarters. An off-balance operator with an
awkward reach into a partially obscured area is unsafe.
If inspection after shipment has revealed no shipping damage, unpack the unit by removing
all hold-downs, tie-downs, bolts, nuts, etc. Remove the envelope with the electrical
schematics and instruction manual from the base evacuation area.
You can now have the machine lifted from the skid. To lift and move the granulator safely
and correctly, cover any sharp corners or edges, and use the type of equipment that has the
most appropriate features and capacity. Use the designated lifting points, and do NOT lift the
machine by the hopper handles or guards.
3-2 Belt Tensioning
Belt drives should initially be tensioned at the “run-in” recommended force. Check the
tension at least twice during the first two days of operation. After the belts have seated
themselves in the sheave grooves and the initial stretch is removed, re-tension the belts to
“normal running” and check periodically to maintain tension at the recommended value. See
Section 5-5 on page 23 for the belt tensioning procedure.
