C Type Tubular Chain Conveyor

The C-Type Tubular Chain Conveyor (standard configuration: food/chemical grade; customizable options available: explosion-proof/aseptic/high-temperature resistant) is a closed-loop C-type combined conveyor designed specifically for powders, granules, and small lump materials. Leveraging the company's years of experience in material handling and fluid system integration, it utilizes a core design of "closed-loop tubular chain traction + C-type flexible corner connection + safety interlock protection." Employing a flange quick-installation/floor-mounted/support integrated structure, it boasts advantages such as compact footprint, stable conveying, dust-free operation, flexible steering, low energy consumption, convenient maintenance, and ample safety redundancy. Manufactured in strict accordance with GB 12476, GB/T 19815, ISO 14644, and 3A hygiene standards, it is suitable for temperatures from room temperature to 80℃ (120℃ high-temperature version available upon customization), with a lifting height of up to 25m, a conveying length of up to 80m, and a conveying capacity of 1~50 tons. With a capacity of m³/h, this multi-condition conveyor is widely used in "horizontal + vertical + horizontal" C-type composite material conveying in industries such as food processing, biopharmaceuticals, fine chemicals, lithium battery materials, feed processing, plastic granules, and mining powders. It completely solves the industry pain points of traditional conveying equipment, such as cumbersome turning, high dust levels, excessive material residue, material jamming, and inability to adapt to clean/explosion-proof conditions. It achieves **zero dust leakage, residue-free material conveying, and fully controllable C-type flexible integrated conveying**, helping companies pass various stringent certifications and environmental inspections such as GMP, explosion-proof certificates, and food hygiene and safety certifications.

As a core material conveying equipment for clean, explosion-proof, and dust-free production scenarios, this product is based on the dual functions of "C-type closed flexible combined conveying + full-process safety protection." These three functions work together to connect upstream and downstream equipment such as raw material warehouses, mixing equipment, metering units, packaging lines, and silos, achieving four-fold protection of materials: no dust, no residue, no cross-contamination, and no damage. It balances conveying efficiency and operational stability, and is suitable for demanding conditions such as aseptic production, explosion-proof workshops, and fine powder processing.

C-type integrated sealed zero-leakage conveying : Utilizing a fully sealed steel/stainless steel pipe cavity, it connects two horizontal sections and one vertical section via a dedicated flexible corner module, forming a standard C-type conveying path. It features a built-in high-strength wear-resistant chain and dedicated discs/scrapers, ensuring continuous and stable material feeding within the pipe. There is no dust spillage throughout the process, with a leakage rate of <0.01%, eliminating workshop dust, material moisture, and cross-contamination issues. It can convey a variety of materials, from ultrafine powders (such as flour, pharmaceutical powders, and lithium battery cathode materials) to small particles (such as plastic particles, nuts, and granular pharmaceuticals), with virtually no material damage or residue. The pipe's inner wall is smooth with no dead corners, and the corners feature a large-arc flexible transition design to prevent material accumulation and jamming, adapting to the need for turning in confined spaces and meeting the high purity and cleanliness requirements of the food and pharmaceutical industries.

Differential pressure/blockage/temperature linkage early warning + low energy consumption and long-term operation and maintenance : The standard configuration includes a PLC online monitoring system with monitoring points set at two horizontal sections, a vertical section, and two corners. It presets three threshold levels for differential pressure, blockage, and over-temperature, and automatically alarms and shuts down the machine in case of abnormalities. It adopts a low-resistance chain drive and a load-sharing disc design, which reduces the energy consumption of operation by 30% to 40% compared to the traditional combination of "two-section horizontal conveyor + vertical elevator". The disc/chain/pipe/corner module adopts a quick-release buckle + sealing pressure ring structure, which can be disassembled, cleaned and replaced by a single person without tools. The service life of vulnerable parts can reach 1 to 2 years under normal temperature and clean operating conditions. The pre-filtered dustproof end cover can be repeatedly cleaned, which greatly reduces operation and maintenance costs and downtime losses.

Explosion-proof and sterile dual safety protection + wear-resistant design : Utilizing a tenon-and-mortise seal + double silicone rubber sealing ring structure, the enclosure, pipes, and corner modules are integrally welded, ensuring excellent sealing performance. The explosion-proof model is equipped with an explosion-proof motor, anti-static chain, and spark detection and extinguishing system, complying with GB3836 standards and suitable for flammable and explosive dust/gas environments. The sterile and hygienic model is made of 316L stainless steel, polished without dead corners, and can withstand CIP/SIP online cleaning and sterilization, meeting GMP and FDA hygiene requirements. It features overload protection, chain breakage detection, and anti-reverse device, and is equipped with anti-jamming sensors at corners to prevent abnormal system damage and ensure long-term safe and stable operation of the equipment.

1. Compact footprint, flexible C-shaped connection, highly adaptable.

The C-type combined layout integrates two horizontal conveying sections with one vertical lifting section, achieving flexible turning through flexible corners. It eliminates the need for additional transfer equipment and complex pipeline layouts, and occupies only 30% of the area of traditional combined conveying equipment. It is particularly suitable for space-constrained scenarios such as clean rooms, small workshops, multi-level production lines, and densely populated equipment areas. The length of the two horizontal sections, the height of the vertical section, and the corner angle can be flexibly adjusted according to the workshop layout, directly connecting to equipment at different positions and heights upstream and downstream without the need for large-scale plant renovations. The flange interface conforms to the GB/T 9113 standard and can be directly connected to existing silos and production lines, adapting to various workshop layouts and process requirements.

2. Modular customization, covering all material types and adaptable to various working conditions.

We can flexibly customize pipe diameter, chain material, disc type (flexible/rigid), length of two horizontal sections, and height of vertical sections according to customer material characteristics and working conditions. Materials include 304 stainless steel, 316L stainless steel, and carbon steel with anti-corrosion coating. For viscous materials, we can choose anti-stick coating pipes, and for abrasives, we can choose wear-resistant ceramic linings. Corner modules can be customized with wear-resistant bushings and different curvatures. From ultrafine powders to small particles, from room temperature to high temperature, from ordinary working conditions to explosion-proof/sterile conditions, we provide full coverage and can meet the personalized C-type combination conveying needs of different industries.

3. Low energy consumption and low noise, resulting in outstanding economic efficiency in operation.

The optimized chain drive, lightweight discs, and large-radius flexible transition design at corners significantly reduce material conveying resistance, resulting in a substantial reduction in motor power requirements and energy consumption that is more than 30% lower than traditional combined conveying equipment. The sealed pipeline structure effectively isolates operating noise, with operating noise ≤65dB(A) (floor-mounted model), far below workshop noise standards. The lifespan of vulnerable parts is clearly defined, and replacement cycles can be precisely controlled through online monitoring, reducing downtime and consumable procurement costs, resulting in outstanding long-term economic efficiency.
