Custom Feed Auxiliary Equipment Manufacturers

Custom Feed Auxiliary Equipment Manufacturers

As one of the established Custom Feed Auxiliary Equipment Manufacturers in China, Goldlong Machinery And Engineering Co., Ltd. supplies the functional supporting equipment that keeps material flow, dust extraction, distribution and machine protection reliable across feed processing plants. Our range includes round and square pulse dust filters, rotary distributors, tubular magnets, pneumatic three-way valves, air locks, fans, side gates and slide gates. We build these units as engineered parts of complete feed milling systems, not as unrelated components.

Depending on your project, we can supply auxiliary equipment for direct replacement, for a new process module, or as part of a turnkey feed mill. We support the line from process design through manufacturing, installation, commissioning, training and after-sales service, and we have exported complete projects and machinery to markets in Europe, Asia, Africa and beyond. For the process machines that connect to this auxiliary range, review the complete Product Center.

Our Other Auxiliary Equipment Range

Each auxiliary unit has a defined job in the feed production chain. The table below summarises the equipment family we manufacture and where it normally fits in a plant.

The TFPX rotary distributor is supplied with 4 to 16 outlets. Standard 219 mm spout units handle 30–80 t/h and 250 mm spout units handle 40–100 t/h, each with a 0.55 kW drive.

Application Fit Across Feed and Biomass Process Lines

Auxiliary equipment is specified according to the process duty around it. In poultry, pig and livestock feed mills, the critical tasks are reliable distribution to multiple bins, protection of the grinding and pelleting stages, and control of dust in the working environment. In aqua feed and extruded pet food plants, the focus is on stable sealed discharge under the filter or cyclone, smooth pneumatic distribution of meal and coated pellets, and protection of the extruder and drier from contamination.

These products also appear in biomass pelleting lines, grain storage systems and compound fertilizer plants, where material flow properties and dust loads often differ from standard feed ingredients. Before proposing a configuration, our engineers review the bulk density, particle size, moisture, temperature, abrasiveness and flowability of the product being handled.

Critical Specifications and Selection Variables

We select auxiliary equipment from process data rather than from a fixed size list. The following variables determine the model, actuation and arrangement:

• Required conveying or extraction capacity in tonnes per hour or cubic metres per hour.
• Number and diameter of outlets for rotary distributors, typically 4 to 16 stations in our TFPX range.
• Air volume, filter area and bag length for pulse dust collectors.
• Material characteristics: bulk density, flowability, moisture, temperature and ferrous content.
• Available headroom and footprint, especially when a filter or distributor is placed above bins.
• Actuation and control interface: manual, automatic, remote signal, interlocking with upstream and downstream machines.

Representative Pulse Filter Data

Our round and square pulse filters cover a wide range of workshop ventilation and machine dust collection duties.

Air volume ranges shown are for our standard units. We adjust the number of filter bags, bag length and fan duty to the actual pickup points and workshop ventilation targets of your project.

Quality Control, Testing and Project Support

Manufacturing is carried out in our own 14,000 m² facility in Liyang, Jiangsu, China, with ERP-based production management and controlled shop operations. Our engineering team can adapt standard units based on customer drawings or samples to meet specific process needs. Each auxiliary machine is inspected before shipment: operation, sealing, safety-related elements and the complete function of the unit are checked against the process drawing and the electrical or pneumatic interface.

Our commitment to customers includes strict quality control, on-time delivery, transparent project communication and a 24-hour rapid response mechanism. For turnkey projects, we handle installation, commissioning and operator training; after commissioning, we continue with remote diagnostics, technical consultation and spare parts supply. Common wear components are kept in stock so that replacement can be arranged quickly.

Configuration, Installation and Maintenance

Because most auxiliary equipment is installed around existing process machinery, we adapt the unit to the site layout rather than forcing the layout around a standard frame. We need to know headroom, wall or floor mounting, bin arrangement, connection sizes and the distance to the control panel before finalising dimensions. Filters and rotary distributors are designed for modular transport and installation, with easily accessible filter bags, inspection doors and maintenance points.

For ongoing reliability, we focus maintenance advice on filter bag condition, pulse valve timing, magnet surface cleaning, air lock rotor clearance and slide gate wear. These components see the most abrasion in feed and biomass applications, and our service team can help your operators set up a simple inspection schedule.

Frequently Asked Questions

Can you include auxiliary equipment in a complete turnkey feed mill?

Yes. We provide turnkey solutions from process design and equipment manufacturing to installation, commissioning and operator training. Pulse filters, rotary distributors, magnets, gates and air locks are integrated into the same process drawings as the Pellet Mill and Bucket Elevator and Conveyor systems.

How do we decide between a round and a square pulse filter?

The round TBLMy range is compact and flexible for limited spaces and normal workshop dust loads. The square TBLMFa range provides larger filter areas and higher air volume capacity, making it the better choice when dust concentration is high or several process machines are connected to one collector. Bag length can be 1,000, 1,500 or 2,000 mm, or customised.

What information do you need for a rotary distributor proposal?

We need the number of bins or outlets, pipe diameter, capacity per hour, available headroom, material characteristics and the control interface. Our TFPX distributors are available from 4 to 16 ways in 219 mm or 250 mm spout sizes, with gravity-fed automatic positioning and optional self-priming configuration.

How is ferrous metal contamination controlled with your equipment?

We supply TCXT tubular magnets for installation in gravity flow lines ahead of hammer mills, pellet mills, crushers and extruders. The magnet removes ferrous material from the product before it can enter the process machine, reducing wear and protecting final feed quality.

Do you supply spare parts for auxiliary equipment?

Yes. We keep common wear parts and critical components in stock for quick dispatch, and we provide training and technical support so your team can perform routine maintenance. Our after-sales team also supports remote diagnostics and on-site service when needed.
