General introduction:
Instruction of the system The equipment is mainly used to unload and load grain to truck. Via grab type gantry crane to grab grain, then through relevance travelling mechanism of gantry crane to put the grabbed material on the above of load system, then open the grab via gantry crane's PLC control system,the grain will be load into the hopper directly, on hopper, have a electric hydraulic push rod control device, it is use to control the output of grain, to make the hopper work safety, effective and improve working efficiency when load grain to truck. This equipment have two parts, up side parts and down side parts,because open mouth of feeding funnel is larger enough, so it is difficult for it to cause dust. And at the feedopening of hopper, have installed induced draft cover, so that it can avoid too much dust when loadingmaterial to trucks. All adsorbent dust will fall back to the parts of feed opening via back flushing of dirt catcher,This equipment adopted advanced technology from foreign, reasonable design, and work at a very good condition.
1.The Unloading Rubber Tires Dusting Proof Mobile Port
Hopper is an economical and ecologically sensitive solution fulfilling all needs for the efficient import of dry bulk cargoes. 
2.The hoppers are designed to suit the characteristics and flow properties of virtually any bulk material. 
3.Rates of 5,000 t/h may be achieved, subject to the grab crane performance. 
4.Unloading with traveling hoppers has the advantage of being a very flexible solution. 
5.The throughput of the terminal can be increased by adding one or more hoppers, provided the collecting belt conveyor and the subsequent handling equipment are designed for future capacity increase with larger vessels.Imported raw materials such as coal, clinker, slag etc. are offloaded from up to 25'000 DWT ships at the Owner's port facilities at the Davao plant site.
 
The Owner will employ two ECO-hoppers running on rails on the quay side to receive the material from the ship's cranes, for transport to the appropriate storages at the plant. In order to facilitate this, the existing (currently unused) belt conveyor system needs to be upgraded by the Owner to meet the 700 t/h ship offloading capacity requirement and to accommodate the moving filter units included in the Eco-hooper package.
