Specification of hopper
1.Details
- Name:Movable dust proof hopper
- Productivity : 1000-1500t/h-
- Capacity:35cbm
2. Instruction of the equipment
Zishi Hopper Bulk cargo operators require equipment, solution and expertise to help reduce dust missions at discharge, while maintaining maximum unloading productivity, we provide the technology and expertise to achieve this with world class design and engineering solutions.
The equipment is mainly used to unload and load bulk cargo to truck. Via grab type gantry crane to grab cargo, then through relevance traveling 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 bulk cargo will be load into the hopper directly, on hopper, have an electric hydraulic push rod control device, it is used to control the output of cargo, to make the hopper work safety, effective and improve working efficiency when load cargo.

5. Tech details:
The steel plate is incised by numerical control machine, and the advantage is:
< style="text-align:left;" >
Slinky and indentation has no stress;II. The aperture between the welding plates is thin, the welded stress is small and the welding line without crazing.It was protected by gas when welding; the welded stress is small and the welding line without crazing.
The holes of up beam, press rods, low beam and scoops are bored by machine, it can ensure the concentric.
The bent plate of the scoops is dealt with by cold machining to make the scoops and other parts to be the exact size and appearance
Other specification not referred are according to the standard of making hopper and the company standard at the Ministry of Communications.

. Notice and Maintenance
< >
The hopper should not be hitted frequently by the grab.Across the guard rail is prohibited. Please make a safe preparation when need to check and repair the hopper outside the guard rail. Be careful when going up or down to the hopper. Jumping and playing are prohibited.All the joints of the lines should be examined regularly.All the electrical equipment should be operated safely and checked regularly. All the bolts should be checked regularly, to see if there are looseness and fracture or not. If there are looseness and fracture in the bolts, stop operation and replace the bad bolts, then go ahead the operation. The dust catcher should be checked and maintained regularly.Use four same steel wire ropes to lift the hopper, and the four pillars (legs),should be stressed equally and stably.When turning on the power source, to see the turning direction of the air compressor (to adjust the phase line).Turn on the four push-buttons, to see if the motor runs normally. The dust catcher can not work if one motor doesn't run.(The dust catcher will be blanked off.)Let the hand spike and windlass run for a while, to see if the limiting is normal. The weld line of the hopper should be checked regularly for the hopper runs with vibration. If there are cracks in the weld line, stop operation and repair the weld lines, then go ahead the operation.The scoops should be cleaned after operation. Let the valve in the safe opening position.8.

During building the hopper, the buyer can go to the seller's factory to supervise and check the quality of the hopper.
When deliver, the manufacture should provide the general drawing of the hopper and wearing parts drawing. Operation Manual.
