DOVE vibrating grizzly feeders are highly effective and popular Grizzly screener/feeders with a history of reliability and durability in the mining, aggregate, construction, and various other industries. They are designed for continuous and uniform screening and feeding of selected size of ore in various processing plants design and configuration.
DOVE Vibrating Grizzly Feeders are designed with the following components:
- The Pan section, which is basically where the feed is deposited from the feed hopper, or in the case of the portable or mobile plant, from the excavator or Conveyer belt.
- The Discharge section, which is immediately following the Pan section, which consist of the Grizzly section, which is configured with Gaps between the Grizzly Bars, which allows the undersize material to pass through before discharge to the next component of the processing plant, which is either a type of primary crusher in Hard Rock processing plant, or a Trommel in case of Alluvial processing plant, or a classifier/ Vibrating screen in solid waste treatment plant, or a conveyer assembly to transport the material, etc.
- Vibrating Mechanism, which is located under the Feeder, where also the feeder is configured with heavy duty springs on each side, which allows the feeder to vibrate via the mechanism located under neath the Pan section. The feeder is designed with a shallow wall, to protect the vibrating mechanism and the Electric motor from any feed material which may miss the Feeder during the loading of material and fall off the Feeder. The Grizzly Feeder is designed with a certain angle, which allows the material to get further lose and move forward from the Pan section to the Discharge section, by the combined action of Vibrating force and Gravity, while segregating the material.
- Material Segregation, Material on continuous basis moves forward from the Pan section to the Grizzly section. The Vibration force results in segregation of material and the finer particles smaller than the Gap in the Grizzly bars section goes through the Grizzly bars gap and settles in the bottom channel bellow the Grizzly section, ready for the next step of the process.
In the case of Hard rock plant where the segregated fine material is selected by Grizzly feeder, the bypass fine material decreases the amount of oversize material going to the crusher, which results in selection of smaller capacity crusher and subsequently in saving in maintenance and spare wear parts. The segregated fine material can be combined with the output of the crusher to go to next step in processing and recovery, or if there are no economic value, it can be discarded.
In the case of Alluvial mining, the segregated fine material are collected by conveyer and move to classifier and concentrators for recovery of minerals. The over size rucks are discarded, or in some cases can move to crushers.
Vibrating Grizzly Feeder is an important item of equipment, integrated to various types of processing plants for segregation of material, and to eliminate over capacity in the design of processing plants, which results in economic value for project.
