Conveyor belt for powder materials

Product Introduction

Conveyor belt for powder materials is a continuous conveying equipment designed for powder materials with small particle size, easy flow or easy adhesion. The powder is transferred from the feed end to the discharge end through the movement of the ring conveyor belt. Its core function is to convey powder materials stably, efficiently and with low loss, while meeting special requirements such as dust prevention, anti-adhesion and corrosion resistance. It is specially designed for conveying fine powder, micro powder and other high-flowability and high-dust materials. It is widely used in bulk material conveying systems with high environmental requirements in industries such as building materials, chemicals, and electric power.

Common powdered materials

Powdered materials refer to materials with very small particle sizes and close to powder state. They are often in bulk form and are widely used in building materials, chemicals, electricity, grain and other industries. Common powdered materials include cement powder, coal powder, flour, lime powder, talcum powder, carbon black, mineral powder, fly ash, etc.

Summary of characteristics:

Powdered materials refer to loose solid materials composed of fine particles, and their particle size is usually less than 1mm. They have the following significant characteristics:

Fine particle size: The particle size is usually between 0.001 mm and 1 mm, sometimes as fine as micron level (μm)

Easy to raise dust: It is very easy to drift with the air flow during transportation, causing dust pollution and material loss

Strong accumulation: The friction between particles is large, the fluidity is poor, and it is easy to bridge and block materials

Hygroscopicity/viscosity: Some powders such as cement, lime, flour, etc. have certain hygroscopicity, which may cause adhesion and blockage

Light specific gravity: Many powder materials have a lower density than block and granular materials, but have a large specific surface area and are prone to static electricity accumulation

What is the working principle of conveyor belt for powder materials?

Conveyor belt for powder materials works together through the core components such as the conveyor belt body, drive device, tensioning device, roller system, etc., combined with special designs such as dust prevention, leakage prevention, and anti-static to achieve efficient and stable transportation of powdered materials.

Features of conveyor belt for powder materials

Strong sealing: prevent dust flying and material leakage, optional cover, closed cover, tubular conveyor belt structure

Conveyor belt material: use wear-resistant, anti-stick, anti-static, flame-retardant and other performance materials to prevent powder from sticking or slipping

Conveyor belt structure: recommended corrugated sidewall belt, skirt belt, closed conveyor belt, pipe belt machine, etc., can adapt to inclined or turning routes

Adjustable belt speed: controlled at 0.8~1.6 m/s, the powder conveying speed should not be too fast to prevent dust from being raised

Ancillary devices: equipped with sweepers, material guide skirts, dust collectors, tensioning mechanisms, etc. to ensure stable operation of the system

Technical parameters of conveyor belt for powder materials

Recommended mesh number for conveyor belt for powder materials

Mesh number is a common unit for measuring powder particle size, which refers to the number of holes per inch on the screen. The larger the mesh number, the finer the particles. As shown in the following table:

Application of conveyor belt for powder materials

Food processing industry: Conveying of food-grade powders such as flour and starch, such as wheat flour storage and transportation in flour mills, milk powder batching lines in dairy factories, and baking raw material production lines. Use food-grade PU or silicone powder material conveyor belts, which have a smooth and easy-to-clean surface to prevent material residues from breeding bacteria.

The transportation of pharmaceutical powders (such as APIs) and chemical raw materials (such as titanium dioxide) is common in pharmaceutical preparation workshops and chemical raw material storage logistics lines. When conveying low-fluidity powders, grooved rollers are used to support the U-shaped cross-section, and the skirt prevents the powder from leaking sideways.

Mineral and metallurgical industry: The transportation of industrial bulk powders such as mineral powder, fly ash, and coal powder is common in mine beneficiation plants and ash storage bins in thermal power plants. Wear-resistant rubber conveyor belts with a thickness of 8~12mm are used, and diamond patterns are added to the surface to enhance friction and prevent wear of mineral powder particles.

Building materials industry: The transportation of cement, gypsum powder, putty powder, and ceramic raw materials is common in cement plant finished product warehouses, building materials processing plant batching workshops, and ceramic plant glaze lines. PVC powder material conveyor belts are selected, and the surface is roughened to prevent gypsum powder from adhering.
