Tips to Extend Life of Jeffrey Rader Vibratory Feeders

Jeffrey Rader feeder power unit not properly maintained

TerraSource Global’s Jeffrey Rader brand vibrating feeders are the industry standard for applications such as mining, forest products, recycling, and power. In particular, these machines consistently outperform competitors in terms of reliability and durability. A critical factor in ensuring this level of quality and performance, however, is maintaining a regular service schedule of machine inspections and proactive replacement of wear parts.

Jeffrey Rader vibrating feeders are designed with the end user in mind, with an emphasis on simplified maintenance. All serviceable components can be quickly and easily accessed, greatly reducing downtime and enhancing customers’ ability to perform sound maintenance practices as outlined below.

NOTE: ALWAYS LOCKOUT MAIN DISCONNECT SWITCH TO FEEDER BEFORE ATTEMPTING WORK. THIS IS CRITICAL BOTH FOR THE SAFETY OF YOUR WORKERS AS WELL AS EFFECTIVENESS OF THE EVALUATION.

For all Jeffrey EF/HP and NF Feeders – The following recommended checks should be performed every month:

Inspect suspension and safety cables for deterioration. Be sure they are secure in their mounting brackets and all wire clamps are tight.
Be sure feed chutes have a minimum 1” clearance from any contact with feeder pan during operation.
Inspect all deck liners for wear and any buildup of material. Also check that all nuts and bolts are tight.
Inspect vibration absorber springs and brackets for any cracks or damage. Replace as necessary.
Check torque on coupling spring bolts. Re-tighten if necessary. Consult manual for proper torque specs.
Check torque on all other fasteners. Consult manual for proper torque specs.
Inspect interior of power unit. Clean off all dust, dirt and moisture. Check for any damaged or loose electrical connections.
Check condition of stabilizer bars.
A WEEKLY check of deck stroke is recommended. Please consult manual for instructions.

For all Jeffrey EF and HP Feeders – Every month check the following:

Check air gap between magnet and armature. Should be .090 – .093. Adjust as necessary. See manual for adjusting instructions.
Check all magnet and stator mounting bolts for proper torque. See manual for proper torque specs.
Check all center clamp to deck mounting bolts. See manual for proper torque specs.
Check all vibrator bars/shoes for damage or cracks.

For Jeffrey NF Feeders – Regularly check the following as indicated:

For every 200 hours of operation, lubricate shaft bearings. For extremely dusty conditions and or highly humid conditions, shorten interval to 100 hours. CAUTION DO NOT OVER GREASE.
Re-lubricate motor bearings every six months per motor manufacturer’s specs.
Check belt tension in exciter box.
Check bolt torque on eccentric shaft weights. See manual for proper torque specs.

All Jeffrey Rader Feeders have been thoroughly inspected and tested at our factory prior to installation at the customer site. Regular in-service inspection and preventative maintenance programs not only reduce overall maintenance costs but also help prevent serious shutdowns. Regular inspections, periodic bolt tightening, regular cleaning and lubrication, along with replacement of OEM wear parts, help your Jeffrey Rader vibrating feeder maintain optimal performance and extend the life of your equipment.
