Metal Mesh Belt Curved Conveyor, Stainless Steel Mesh Belt Curved Conveyor, Mesh Chain Curved Conveyor

A metal mesh belt turner is a heavy-duty conveying system that uses a metal mesh belt (made of materials such as stainless steel) as the conveying medium. Driven by sprockets, it enables smooth, curved turns. It features high-temperature resistance (up to 600°C), high strength, corrosion resistance, and excellent air permeability.

I. Product Applications

Metal mesh belt turners are widely used in applications requiring high-temperature resistance, high strength, corrosion resistance, and air permeability:

1. Food Processing Industry: Used in drying, steaming, frying, washing, and quick-freezing processes for meat, seafood, vegetables, fruits, and frozen foods; capable of withstanding both high and low-temperature environments.
2. Heat Treatment and Baking Industry: Suitable for the heating and baking conveyance of electronic components and food products; the metal mesh belt withstands high temperatures, overcoming the disadvantages of conventional belts prone to tearing, puncturing, and corrosion.
3. Pharmaceutical and daily chemical industries: Used for conveying pharmaceuticals and cosmetics; the metal material is hygienic, easy to clean, and highly corrosion-resistant.
4. Logistics and packaging industries: Used for curved conveyance of cartons, packaging bags, and other unit loads, enabling changes in spatial flow direction and saving factory floor space.
5. Ultrasonic cleaning equipment: Metal mesh belts can be used in conjunction with cleaning equipment; they are water-resistant and corrosion-resistant.

II. Product Advantages

The core advantages of the metal mesh belt curve conveyor lie in its high-temperature resistance and high-strength structure:

1. Excellent high-temperature resistance: Capable of conveying materials at temperatures below 600°C, suitable for high-temperature applications such as clinker handling, baking, and heat treatment.
2. High conveying capacity: Maximum conveying capacity reaches 526 m³/h, with a maximum incline of 60 degrees, meeting high-volume conveying demands.
3. High Strength and Long Service Life: The conveyor belt is made of metal (stainless steel), offering high strength, minimal elasticity, and resistance to deformation. The drive chain is constructed from heat-treated alloy steel, ensuring wear resistance and durability.
4. Corrosion Resistance and Hygienic Design: The stainless steel material resists acids, alkalis, and corrosion. With no pores or gaps, it does not easily adsorb impurities and complies with food hygiene standards.
5. Flexible Layout and Space-Saving: Supports various turning angles including 45°, 90°, 180°, and 360°, enabling material diversion in confined spaces. Multiple horizontal and inclined sections can be combined in various configurations.
6. Low Energy Consumption: Load-bearing rollers use rolling bearings (replacing sliding friction with rolling friction), reducing operational resistance by 55%–65% and minimizing power consumption.
7. Minimal deviation: Utilizes sprocket drive transmission, preventing the conveyor belt from meandering or deviating, ensuring stable and reliable operation.

The key feature of the metal mesh belt turner lies in the coordination between the stainless steel mesh belt and the sprocket drive system. By using chains with different pitch lengths on the inner and outer sides (27 mm on the inner side and 53 mm on the outer side), a speed differential is created, enabling the mesh belt to turn smoothly along the curved track. Additionally, the outer ring of the mesh belt is equipped with special guide rollers to prevent misalignment.
