A sleeper (or slotted) sieve is a tool used to separate (or separate) particles or matter from a mixture by size. It consists of a frame and a perforated body. The slotted sieve can be used in various industries such as mining, chemical, pharmaceutical, paper, oil and gas, food processing; electronics, mineral processing and agriculture.

The main feature of slotted sieve is its ability to separate component mixtures according to their size, and to separate a greater percentage of liquid from solid, according to their size. The mesh size in the sieve can be customised to suit different separation tasks. The spar sieve can also be used to improve the quality and productivity of liquid purification or substance sorting processes. The main advantage is the ability to separate materials based on differences in their physical properties such as size, shape and density. This can significantly improve the efficiency and accuracy of the separation process.

In addition, slotted sieves have minimal hydraulic resistance due to their design and are easy to rinse after handling a substance or material.

Slotted sieves have a number of advantages over other types of sieves:

It’s high separation efficiency: slotted sieves have very fine meshes, which allows them to be used for efficient separation of small particles or liquids.
Ease of use: slotted sieves can be easily mounted, dismantled and replaced, thanks to the „stand-alone“ design.
Durability: slotted screens are usually made from durable materials such as stainless steel, which increases the working life many times over and minimises any damage or defects during operation.
Flexibility: slotted screens can be manufactured in a variety of sizes and shapes, allowing them to be used in a variety of separation processes and customised solutions.
Overall, slotted sieves are an important tool in production processes due to their high efficiency – this makes them a popular choice in a variety of industries. Thus, spalt (slotted) sieves play an important role in quality assurance in manufacturing.
