Conveyor belt for high temperature materials

Product Introduction

Conveyor belt for high temperature materials is an industrial transmission component designed specifically for conveying materials with high temperature characteristics. Its core function is to stably convey materials in a high temperature environment while ensuring that its own structure is not damaged and its performance is not significantly reduced. Based on high temperature resistant materials, special industrial equipment designed in combination with material temperature, physical properties and transmission requirements, through structural optimization, balances stability, wear resistance and functionality in high temperature environments, and is widely used in temperature-sensitive heavy industrial scenarios.

Challenges faced by conveyor belt for high temperature materials

Material expansion and deformation: Increased temperature causes traditional materials to expand, thereby reducing the stability of the conveyor belt.

Reduced strength: High temperature weakens mechanical properties and increases the risk of breakage and damage.

Reduced wear resistance: Materials conveyed under high temperature conditions may cause additional wear on the conveyor belt.

Chemical reaction: High temperature environment may cause chemical reactions between the conveyor belt material and the transported material, affecting its service life.

To solve these problems, it is crucial to select a conveyor belt for high temperature materials with excellent heat resistance.

Mesh number recommendation for conveyor belt for high temperature materials

The mesh number refers to the mesh density of the filter on the surface of the conveyor belt, the unit is "mesh/inch" (number of holes/25.4mm), which is used to control the passability or retention of material particles.

Application scenario:

Low mesh number (coarse screening): such as 20~60 mesh, suitable for conveying large particles of high temperature materials (such as blast furnace slag, coke), allowing fine dust to pass through to avoid blockage.

High mesh number (fine screening): such as 100~300 mesh, used to filter high temperature liquids or fine particles (such as glass molten liquid impurity removal, metallurgical slag liquid separation), high temperature resistance and screening accuracy must be taken into account.

Key technical parameters of high-temperature material conveyor belt

Conveyor belt for high temperature materials is a special conveying equipment designed for continuous or intermittent contact with high-temperature materials. It solves the problems of belt aging, deformation, and strength reduction caused by high temperature through heat-resistant materials, cooling technology, and heat-fatigue-resistant structure.

Parameters	High-temperature belt requirements	Ordinary conveyor belt comparison
Temperature resistance level	T1 (100℃)~T4 (400℃) or customized higher	Ordinary belt (-10~80℃)
Thermal elongation	≤2% (under 200℃)	Ordinary rubber＞5%
Cover thickness	Upper cover 6-15mm (wear resistance + heat insulation)	Ordinary belt 3-5mm
Cooling method	Air-cooled/water-cooled roller, spray system	No cooling design
Life (high temperature)	6 months~2 years (depending on working conditions)	Ordinary belt is only 1-3 months at 200℃

According to the conveying temperature, pipeline belts are divided into different grades:

T1: Temperature resistance ≤120°C (such as ordinary hot powder).

T2: Temperature resistance ≤ 150°C (such as cooked cement).

T3: Temperature resistance ≤ 180°C (such as hot coal slag).

T4: Temperature resistance ≤ 400°C (such as steamed ore).

Higher levels (such as 600°C+) require special materials (such as steel mesh belts or ceramic composite materials).

Application of Conveyor belt for high temperature materials

Metallurgical industry: In the evaporation workshop of the steel plant, the evaporation ore (temperature 500-800°C, mesh number <60, diameter 10-50 mm) is output from the evaporation machine and needs to be quickly piped to the cooler or blast furnace raw material bin. The Conveyor belt for high temperature materials is responsible for conveying the evaporation ore from the tail of the evaporation machine to the next pipeline.

Cement industry: The clinker temperature production line of the factory, high-temperature clinker (200-400°C, mesh number 60-150, diameter 0.1-0.25 mm) is output from the rotary kiln and needs to be conveyed to the clinker cooler or storage. The pipeline belt conveys the clinker cement from the tail kiln to the conveying cooling system. (1-1.5 m wide, 0.5-1.5 m/s in speed)

Chemical industry: In the catalyst production line of a chemical plant, high-temperature catalyst (temperature 200-500°C, mesh size 200-400, particle size <0.074 mm) is output from the reactor and needs to be piped to a cooling device or packaging line. The pipe belt transports the catalyst from the bottom of the reactor to the screening or cooling equipment. (0.6-1 m wide, 0.2-0.5 m/s in speed)

Glass and ceramic industry: In a glass manufacturing plant, hot glass raw materials (such as silica sand, limestone, temperature 300-600°C, mesh size 100-200) are output from the furnace and need to be piped to the molding machine or cooling area. The pipe belt transports the raw materials from the melt discharge port to the next conveying pipeline. (width 0.8-1.2m, speed 0.3-0.8m/s)

Hot fly ash industry: In coal-fired plants, hot fly ash (temperature 150-250°C, mesh size 150-300, diameter 0.05-0.1mm) is output from the bottom of the boiler or the electric precipitator and needs to be piped to the ash storage or recycling system. Conveyor belt for high temperature materials transfers fly ash from the ash hopper to storage or processing equipment.
