Custom Universal Industries Bucket Elevator Manufacturers

Goldlong Machinery And Engineering Co., Ltd. supplies the lifting and conveying machines that keep feed, grain, chemical and biomass plants moving between process stages. The bucket elevator and conveyor line we manufacture consists of TDTG series bucket elevators, TLSS series screw conveyors and TGSU self-cleaning drag conveyors. As a China-based manufacturer and turnkey project contractor, we size each unit around the actual layout, tonnage and material behaviour rather than offering a generic machine.

Our Custom Universal Industries Bucket Elevator page summarises the available range, the engineering options we build, and the project information we need before preparing a proposal.

Three Conveying Lines, One Engineering Approach

See the full Product Center for the upstream and downstream machines these conveyors connect.

Application Fit by Process Stage

• Raw material intake and pre-cleaning: TDTG bucket elevators lift grain and meals from receiving pits to pre-cleaners and storage bins.
• Grinding and batching: TLSS screw conveyors move ground material under hammer mills and above mixers; TGSU drag conveyors serve multiple bins.
• Pelleting and cooling: bucket elevators transfer pellets from coolers to crumbler, sifter or packing lines.
• Grain storage and drying: high-capacity TGSU drag conveyors move wet and dry grain; TDTG elevators feed silos and dryers.
• Chemicals, fertilizer and biomass: the same range works where dust, moisture, abrasion or slight caking must not interrupt flow.

Capacity and Sizing Reference

Rated capacity depends on material density, conveying height, angle and feeding method. The table lists common models and their stated capacity ranges; power is fixed by the elevator height and capacity for TDTG, and by conveying length and volume for TGSU.

Configuration and Engineering Options

• Bucket elevator: height, bucket size and spacing, belt type, head and boot design, inlet and outlet positions, gravity or screw tensioning, explosion venting, balance pipe, speed monitoring and optional belt misalignment alarm.
• Screw conveyor: conveying angle, pitch, shaft and trough material, inlet and outlet positions, drive arrangement and modular section lengths for future line changes.
• Drag conveyor: conveying length, inclination angle, chain and scraper material, intermediate inlet and discharge points, and self-cleaning geometry for wet or sticky materials.
• Structural integration: support steel, flanged connections, covers and access doors can be matched to the plant's process flow.

The Series Bucket Elevator product page gives the full model overview. For chain-based transfer, the Self-cleaning Drag Conveyor page details the TGSU range and sizing logic.

Controls, Safety and Automation Integration

Our conveying machines are designed to work with the plant control system rather than as isolated units. Standard monitoring devices on the bucket elevator can be connected to a PLC for speed, belt slip and misalignment alarms. The anti-reverse device protects the belt and buckets during stopping or power loss. For turnkey projects, we also design, install and commission the electrical control system, including interlocks between conveyors and upstream processing machines.

• Speed monitoring and anti-reverse protection prevent bucket elevator damage during blockages or power failure.
• Belt misalignment alarm protects the belt from edge damage.
• Interlocks stop upstream feeders when the conveyor is not running.
• Explosion vent and balance pipe improve safe operation on dusty materials.

Quality, Commissioning and Lifecycle Support

Our own 14,000 m² manufacturing facility and ERP management system give us control over fabrication, assembly and traceability. Before shipment, each machine passes a comprehensive inspection covering performance, stability, safety and full system testing. For complete projects, our scope runs from requirement analysis and process design through equipment manufacturing, installation, commissioning and operator training.

• Turnkey scope: we deliver the conveyor as part of a complete feed, grain or fertilizer handling system, not just as a standalone component.
• Spare parts: common wear parts and critical components are held in stock for rapid dispatch, reducing downtime.
• Training and support: we train operators in machine operation and maintenance, provide remote diagnostics and respond quickly to operational issues.
• Export experience: our equipment and turnkey projects have been delivered across Russia, Romania, Indonesia, New Zealand, the Philippines, Bangladesh, Pakistan, Iran, Saudi Arabia and other markets.

Information We Use to Configure Your Solution

We build a proposal around the following information. The more complete the data, the closer the first layout will be to final installation.

• Material data: bulk density, particle size distribution, moisture content, abrasiveness, flowability and temperature.
• Duty: required capacity in tonnes per hour, vertical lift height, horizontal distance, inclination angle, and number of inlets and discharges.
• Process interface: upstream and downstream equipment, feed method, and whether the conveyor runs continuously or in batches.
• Plant and installation: available headroom, footprint, support steel, access for maintenance, and indoor or outdoor location.
• Utilities and control: voltage and frequency, PLC system or line control interface, interlocking requirements and dust or explosion protection needs.
• Sample or drawings: if you have a process flow diagram, plant drawing or material sample, we use it to verify the configuration before quotation.
