Vacuum filter conveyor belt

Filter belt is a core component of filter machine, mostly made of annular rubber material, with grooves and drainage holes on the surface, often with a skirt. Through the synergy of gravity and vacuum suction, it achieves efficient solid-liquid separation. It features durable skirt, stable filtration effect, and customizable options, widely used in metallurgy, energy, chemical, and environmental protection industries. Regular inspection and cleaning maintenance are crucial for maintaining its performance.

Applications

• Vacuum filter conveyor belts are suitable for solid-liquid separation in the petroleum, chemical, pharmaceutical, dye, food, metallurgy, mining, and power generation industries. They can also be used in industrial and civil wastewater treatment, such as phosphoric acid, potassium carbonate, potassium sulfate, alumina, citric acid, barium sulfate dehydration, and power plant desulfurization.

• Vacuum filter belts include rubber filter belts, extra-wide filter belts (width up to 6500mm), and circular filter belts. We can also customize filter belts for special purposes.

Features

Vacuum filter conveyor belts can continuously complete filtration, washing, adsorption, filtration, and filter cloth regeneration processes. They have advantages such as high filtration rate, strong production capacity, simple operation, and high washing cleanliness.

• Good chemical resistance • High temperature stability • Good anti-aging and anti-sun cracking performance • High strength • Low elongation • Transverse stability

FAQ

Characteristics of Polyester Conveyor Belt

High modulus, low elongation, good heat stability, impact resistance and other characteristics, suitable for medium and long distance, high-speed, high-speed conditions of conveying materials.

Body material for heat-resistant conveyor belts

The subject material of the heat-resistant conveyor belt includes a skeleton material, a covering layer and a base material.

Selection of the diameter of the conveying roller

The selection of roller diameter should consider the following factors: the average specific pressure between the conveyor belt and the roller surface, the amount of deformation of the bag and the bag, the utilization rate of the allowable strength of the conveyor belt, the frequency of bending of the conveyor belt, the installation location of the conveyor and the conditions of use.

Main material of nylon conveyor belt

The main material of the nylon conveyor belt is nylon, but it does not have enough tension, so it is necessary to add a layer of industrial polyester cloth between nylon and nylon to increase the tension when making the finished product.

The advantages of the pattern conveyor belt

The pattern conveyor belt can ensure the smooth transportation of materials, with anti-skid, impact resistance, and high temperature resistance.
