Equipment:
• Two screw conveyors (15’ x 12”)
• One bin sweep (15’ long)
Learning Objectives:
Install, operate and inspect screw conveyors and bin sweeps
• Learn how a screw conveyor should be installed in its case.
• Identify where grain should be dropped when loading into a screw conveyor.
• Determine the correct size drive motor for the load (tripping, excessive wear in the drive shaft, pulley, etc).
• Recognize excessive wear in the screw (damage on the shaft, damage of the flights, holes in the case, etc).
Troubleshoot and maintain screw conveyors
• Recognize and repair common problems; determine how they occur and what caused them (mechanical or electrical failure).
• Learn how to change a belt, pulleys, motor, shaft, etc. (this section will work with any drive).
• Perform maintenance on the bearings including hangar or greaseless (lubrication, leveling with the shaft to reduce wear, how to change a bearing, etc).
• Lining of the screw housing to patch any possible holes on the screw housing.
Apply and perform best safety practices and procedures on screw conveyors and bin sweeps
• Identify common safety concerns and discuss OSHA standards
• Study electricity issues such as the causes of overloads in motors and power failure problems
• Learn to operate and troubleshoot hazard monitoring equipment. For example plug switches, speed sensors, bearing sensors; Lock-out, Tag-out procedures, etc).
• Learn how to prevent grain dust explosions in screw conveyors
