Transporting facilities

Concept

• Bucket Elevator is used for vertically transporting or elevating different type of products by buckets which is attached to rubber belts or chains tightly. The buckets are operated by a motor. Platform is designed to head hood part of the elevator, so it is easy to adjust tension of rubber belt or inspect driving parts.

Product features

• The elevator is possible vertical transportation by high position.
• Structure of the elevator is simple and the footprint of the facility is small, so space occupancy rate is high.
• It is easy to manage and install the elevator by using chain and rubber belt.
• The facility is designed to prevent dust scattering and to be dust tight and weatherproof.

Continuous Discharge Elevators

• Buckets are attached on the belts or chains without different gap between buckets. The material which is discharged from bucket on the head pulley pass by on front bucket’s flange. The flange is acted as the chute to the material to go into the outlet spout.
  Transporting speed (m/min) : 15 ~ 40

Centrifugal Discharge Elevators

• Buckets are attached on the chain or rubber belt at regular intervals. The bulk materials which is contained in the buckets are discharged by centrifugal force. The force is generated by operating fast speed of belts or chains. Install fee of the elevator is cheaper than other types’ elevator, but it requires to spend much money for maintenance and repair cost.
  Transporting speed (m/min) : 50 ~ 100
  Transporting capacity (Ton/hr) : 30

Positive Discharge Elevators

• Positive- Buckets are fixed on two strands of chains and same length of bucket spacing. The bulk products are discharged clearly by a snub wheel which inverts the buckets and lead the products to the outlet chute.
  Transporting speed (m/min) : 50 ~ 100

Concept

• Flow conveyor is the chain conveyor which transfers continuously raw materials by friction between material’s particles. The friction is occurred by the chains which hang attachment of special shapes in the sealed duct of squared type or unclosed structure of transport line.

Product features

• Wonjin Tech’s flow conveyor is able to transfer raw materials at consistent speed. In addition, operators can make the material stop at the point where they want.
• Because we have used standardized chains, vibration in the conveyor is low.

Pros and Cons

-Prons-
• Raw materials are transferred in the enclosed gutter, so particles of the material are prevented to scatter in the air.
• The conveyor is able to transfer materials to horizontal, vertical direction.
• Because fulfilled powder in the casing is transferred to the arrival point, it is able to transfer enough amount of transport even though flow conveyor is designed smaller size than other types of conveyors.
• Because the shape of casing is box, it is able to design that casing has strength by itself. Thus, the conveyor is able to install solidly by simple the supports which is attached at the casing.

-Cons-
• Flow conveyor requires less electronic power than screw conveyor, but the flow conveyor spends more the power compared to belt conveyor and bucket elevator.
• Flow conveyor tends to make a noise loudly than other conveyors and it is complicate to repair and maintain.

Concept

• Pneumatic conveyor is a facility that powder is transported by using floating energy. The floating energy is generated by pressure difference gap.

Product features

• The conveyor is able to transport lots of volume in a short time. It is separated by three types, low pressure transportation, high pressure transportation and pulling-air transportation depended on materials’ property.

Pros and Cons

-Pros-
• Footprint of the facility is small.
• Maintenance of the conveyor is easy because a driving part is few. Also, a production automation is able to adapt the conveyor.
• It is simple to moving facility and structural alterations.
• The conveyor is possible to be hygienic disposal, and it doesn’t cause environmental pollution. pollution.
• It is low-risk that dust explosion occurs.
• It is possible to be dry and cooling.

-Cons-
• The materials which contain lots of water can’t be transported by the conveyor.
• Wear is severe in Pipe’s curved surfaces.

Concept

• Screw conveyor is generally used for feeding or elevating bulk materials by rotating screw blade in the ‘U’ type conveyor casing.

Product features

• Wonjin Tech’s Screw conveyor is produced for transporting or elevating pulverized coal, grains, fertilizer, cement and so on in a short distance. It is manufactured that bulk material is prevented to disperse during processing. In addition, inlet and outlet chute are able to attach any position on the casing depended on order requirement. It doesn’t have any problems when using horizontal feeding.

Pros and Cons

• -Pros-
• It is able to manufacture various shapes of screw blade.
• It is able to transport at steady rates.
• Because of designed as sealing structure, fine materials is also able to transport.
• Because structure is simple, the facility almost never have broken down.
• It require less electricity than other facilities for feeding raw materials.

• -Cons-
• Residual substance tend to be remanded between screw casing and screw blade.
• The facility is not appropriated to transfer large-sized materials and strong abrasive powder.

Materials of construction

• STPG, SPP, SS400, SUS304 (Materials of construction is able to alter based on ingredients of a raw material)
