Vibrating primary feeders are used for feeding the material dumped into the primary hopper to the primary crusher. These feeders are driven by vibrator motors or mechanical drive systems with eccentric weight and gearbox. Primary feeders are strong enough for the impact forces of the rocks dumped into the hopper. Also there are special steel liners (Hardox etc.) on sides and bottom of the feeders.
Scalper screens are used for separation of the natural fines in the raw material. Adjustable grizzly spaces helps separation for all kind of material. Grizzly bars are designed very strong and wear resistant. 
Apron feeders are used under the primary feed hoppers when the feed material includes soil or clay and gets sticky with moisture. Apron feeders prevents feeding problems even the material is very dirty and sticky with the help of strong structure and track system.
Wobbler screens are used when the raw material is dirty, humid and sticky. They provide a clean and homogenaus feeding to the primary crusher. By the help of  synchronised shafts having elliptical cams on them, wobbler screens make the separation of soil and clay by preventing blockage.
