UGURMAK UMG Series Vibratory Grizzly Feeders are the main feeder type used in crushing and screening plants. They take place for feeding jaw or impact crushers used in primary stage. Offering high performance even in the harshest conditions, UMG Series feeders can be used for any size of material, from oversized material to small size stream materials. Thanks to the adjustable grill distance, the product size that cannot be included in the primary stage can be changed. It has a very solid chassis. Feeder body is seated on it with helical springs in sufficient number and strength. On this feeder body, there is a large volume bunker in the structure offering high strength. It can be used in all mobile and stationary primary units.

Vibration System

Vibration is the mechanical oscillation around a balance point. In vibrating feeders, this mechanical oscillating movement is created by two vibromotors of the same property. Each swing motion brings movement to the material fed and allows some advance on the feeder. This amount of feed is called the amplitude of the feeder.

Bypass System

The purpose of the grizzly system on the feeder body is to “bypass”. Bypass can literally be referred to as “bridging”. Therefore, the concept of bypass for the crushing and screening plant is explained as “transferring the materials that are not needed to enter the crusher to other levels of the system by skipping this stage”.

The material fed to the crushing and screening process is brought to the facility by being extracted from the quarries by drilling, blasting. For this reason, there is also a small size or clay material that will not be desired as a product in this primary material. Including this material into the process by bypassing it instead of feeding it to the crusher will enable the crusher to be used with higher efficiency. This is the main reason why UMG Series vibrating grate feeders are preferred especially in primary stage. Moreover, since the distances between the grids can be adjusted easily, the product size to be bypassed can be changed.
