Residual sieves are devices used to separate solid particles of different sizes in a liquid suspension. They are commonly used in industrial applications such as water and sewage treatment, mining, food and pharmaceutical industries. Residual sieves can be manufactured in different materials, including stainless steel, polymers and non-ferrous metals, and can have different types of meshes or screens to separate different particle sizes. Grupo EP works with two types of sieves, they are:
Static Sieve is a device that does not have mechanical movement and is used to separate particles of different sizes using a screen or mesh. This sieve is generally composed of a static box that contains the screen or mesh, and an upper cover that allows the entry of material. The liquid suspension is placed in the box, and the larger particles are retained on the screen or mesh, while the smaller particles pass through it.
Rotary Sieve is a device that has mechanical motion and is used to separate particles of different sizes using rotary motion. This sieve usually consists of a cylindrical chamber that contains a screen or mesh, and an upper lid that allows material to enter. The liquid suspension is placed in the chamber, and as it rotates, the larger particles are retained on the screen or mesh, while the smaller particles pass through it.
Rotary screens are generally used in applications that require high processing capacity, such as water and sewage treatment, food industry, mining and chemical industry, as they can process large volumes of material. Static sieves are more suitable for applications with smaller volumes of material and where greater precision in separation is desired.
