Sand Gravel Grizzlies Screening Equipment For Pre - Screening Low Energy Waste

GS GRIZZLY SCREEN

The GS linear motion screens have been designed specifically for heavy scalping duties with the main pur-pose of removing fines from the feed before primary crushing. In conjunc-tion with a facility for bypassing fines ahead of the crusher, GS screens can be combined with reciprocating table feeders when heavy dump loads and high capacities are required.

All GS screens have their vibrating mechanism mounted under the feed pan. The double shaft mechanism
generates an elliptical stroke, which consequently means better feeding as well as a sustained material speed on the screen. The screens are available with 2,3 and 4 grizzly steps for the single deck models, depending on the size of the screen. The double deck models are equipped with three grizzly steps on the top deck and wire or rubber media on the bottom deck. The drive unit incorporates two motors with cardan shafts,meaning that neither gearbox nor gearwheels are necessary - the mechanism is self-synchronizing.
The components of the mechanism are mainly the same as for the LS screens. GS has a maxi-mum feed size of up to 500 mm and a separation of up to 250 mm.

GS-series grizzly screens for tough primary screening of blasted rock,ripped rock or gravel with a high fines content,as well as designed for heavy duty scalping,with the main purpose of removing fines from the feed before primary crushing. 

Mining ore screen grizzly quarry vibrating feeder price dual eccentric shaft exciter generates excitation force. A gear pair-connects the two eccentric shafts, enables the shafts rotate to opposite direction with same speed. Through motor driving, the excitation force generated constantly, the material slides and bounces ahead to crusher on the feeder groove. When material go through the feeder’s grid bars, the smaller material will fall down through the gap between grid bars and be sent to next crushing process. It enables the feeder to pre-screen material and fully ensures the crushing plant’s high crushing efficiency and capability.
