Grizzly Feeders Get Tougher

Grizzly feeders are getting more rugged in order to meet the demands of busy operations. At Unicast, we’re always working to make our grizzly parts, such as vibrating grizzly bars and grizzly panels, more durable and longer-lasting to handle your extreme impact applications. And several original equipment manufacturers have been doing similar work to reduce downtime and make their grizzly feeders easier for their clients to maintain.


Within its line of feeder products, Telsmith offers a group of heavy-duty grizzlies, which it says can easily absorb the impact of trucks repeatedly dumping large stones. It has adjustable gear timing and bolton counterweights to give the feeders optimal feed control, and the company offers replacement Telsmith parts for easier maintenance.

Sandvik boasts that its line of SV grizzly feeders, which handle high capacities of 170 to 2,040 tons per hour, can be customized to allow a client to balance their needs of capacity, weight, impact resistance and other factors. The company has also made maintenance simpler by putting its heavy-duty double shaft mechanism with gears in an oil bath, and hefty, replaceable Sandvik parts cover all exposed surfaces to ensure a long feeder life.

In addition, McLanahan says its vibrating grizzly feeder has a main frame made up of deep, fabricated side frames, tough cross-members and a pan section that includes 80,000 lbs of yield-steel strength, which allow clients to benefit from years of low-maintenance feeder operation.


Unicast’s Honeycomb Grizzly Panels and Tapered Grizzly Panels are cast in one piece in high-strength manganese or proprietary martensitic alloy steel, which helps improve grizzly bar stability and, as a result, save operators from needing to weld repair cracks caused by vibration and heavy impact. They’re also self-cleaning, being tapered to provide good material flow and eliminate the blockage that can arise in inferior parts, and can be custom-built to fit your needs. We offer replacements for many OEMs, such as Williams parts and Universal parts, and for grizzlies we make replacement Metso, FLSmidth and Terex parts, among others.

We can also engineer solutions to solve your specific grizzly part challenges. A Utah limestone quarry was seeing its grizzly panel wear out every four to five months, requiring a costly and time-consuming complete replacement of the panel. The company enlisted Unicast to help it reduce its maintenance costs through a longer-lasting grizzly panel, which we did by bolting our proprietary removable titanium carbide (TiC) tips onto the grizzly panel’s highest wear zone. The easily replaceable tips lasted eight to ten months each, and the grizzly panel itself felt virtually no impact, reducing the quarry’s maintenance costs by 89 percent in that time period.


Stop losing time and money on unplanned downtime caused by insufficient wear parts. Unicast’s industrial wear parts can withstand extreme temperatures and tough working conditions longer than other products. Contact us at 1-866-728-3557 or visit our website to learn more.
