Chains
Chains and Carry Rollers
MMD Plate Feeders feature two strands of heavy duty chain with a sealed and lubricated hardened steel construction. The process of hardening each part of the assembly is controlled to produce the ultimate in toughness and resistance to shock, as well as maintaining uniformed wear throughout the parts long service life.
The sealed chain prevents abrasive material from entering the chain's internal parts, that can cause premature wear, extending chain life by 20-30%. Sealed and lubricated chain also reduces friction, lowers costs for maintenance, and increases efficiency. The chain has split master chain links at intervals for easy removal and re-installation of small sections.
Carry and Return Rollers
Carry Roller
The top carrying rollers are a standard tractor type, spaced at intervals along the length of the feeder, to ensure smooth travel of the deck during operation. In the loading zone the rollers are tightly spaced together, providing extra strength and support to take care of the undefined impact loads in this area. The bearings on the carrying rollers have been engineered to accept high impact loads and they are sealed for lifetime lubrication and extended wear life.
Return Roller
The return strand of the feeder is carried back on specially heat treated steel return rollers. The rollers are bolted onto the lower joist, and the whole return roller assembly can be simply withdrawn through a hole in the web of the joist facilitating easy removal and installation from the side of the feeder.
