Industrial screens Manufacturers online

Industrial sieves are mechanical devices used in various industrial processes to separate, classify or filter materials. They consist of a mesh or perforated surface that acts as a barrier through which certain particle sizes can pass while others are retained. Here are some key features and applications of industrial strainers:

Features of industrial strainers:

Materials:

Metal: Often made of stainless steel or other durable metals to resist corrosion and wear.
Plastic: For specialized applications where chemical resistance or lightness is important.
Mesh: Often made of wire mesh or synthetic materials that are flexible and durable.

Mesh size:

The size of the openings in the sieve determines the particle size that is allowed to pass through. Screens are available in different mesh sizes, from coarse to very fine.

Types:

Circular screen: Cylindrical or circular screens, often used in rotating trommel screens.
Flat screen: Flat screen panels used in vibrating screens.
Wire mesh: Flexible nets that can be tensioned into various shapes.

Vibrating mechanisms:

Many screens are equipped with vibrating or shaking mechanisms to increase the efficiency of separation by moving the material over the screen and passing smaller particles through the mesh.
Applications of industrial screens:

Mining and minerals:

Separation and classification of ores and minerals by size.

Food industry:

Cleaning of grain, separation of sugar and salt by particle size, filtration of liquids such as juices.

Chemical industry:

Filtration and separation of chemicals and powders.

Pharmaceutical industry:

Production of medicines by filtration and purification of ingredients.

Construction industry:

Separation of sand and gravel, recycling of building materials.

Water and wastewater treatment:

Filtration of suspended solids from water and wastewater.
Types of industrial screens:

Vibrating screens:

Utilize vibrations to move and separate materials, especially effective for fine-grained materials.

Vibratory screens:

Use mechanical agitation to move materials across the screen.

Trommel screens:

Rotating cylinders with screen surfaces, often used in waste management and mining.

Centrifugal screens:

Use centrifugal force to separate liquids from solids, often used in the food and pharmaceutical industries.
Industrial screens are essential for many industrial processes as they can increase production efficiency, improve product quality and reduce energy consumption. Their selection depends on the specific requirements of the respective process, such as particle size, throughput and material properties.
