Primary Loading Bunker
The loading bunker is the primary part of any stone crushing line, which is used to load the product with a truck, bulldozer, or excavator in large amounts, further to be sent to the primary crusher. The design of this unit includes a large volume tank with a feeder at the bottom, where the feeder runs on vibration for a constant supply of the material to the crusher.
1. Vibrating feeder - is an inclined flat panel at the bottom part of the feeding bunker, which is vibrating by means of double vibromotors underneath. Vibrating feeder can be manufactured complete flat or with grizzly system, where grizzly system is manufactured as single or double layer, depending on bypass amount of the loaded product.
2. Installation chassis is a construction on which feeding bunker walls and vibrating feeder springs are mounted, which creates the whole construction after installation.
3. Side supports are connect points of bunker side walls to the installation chassis, which are manufactured in special design to withstand heavy loading pressure.
4. Side walls are additional supplementary panels of the feeding bunker that are connected to the lower walls during installation. These side walls create main volume of feeding bunker.
5. Chain connects are points of heavy chain connects that are hung to protect reverse bouncing of stone particles. These chains are specially important in crusher feeding regulation.
*** Feeding bunkers undergo much impact and wear during loading. To prevent this, feeding bunkers are covered with bolted wear plates depending on customer choice.
*** For easy and compact transportation, in mobile equipment feeding bunkers are manufactured folding type. This R&D solution for mobile equipment results in easy and fast installation of the equipment.
*** Vibrating feeder is controlled by start-stop button in equipment operating. Additionally, control system gives opportunity to control vibromotor rotation speed, which allows to regulate feeding process according to other units of crushing-screening line.
