What Is a Sieve Shaker?
A sieve shaker is an instrument used to sort materials based on grain size. This is achieved by stacking sieves of various sizes, from smallest to largest, into a mechanism that automatically vibrates them. Sieve shakers are versatile tools used across different fields, from scientific research to civil engineering and waste management.
The choice of appropriate sieve size and shaking method varies depending on the material’s type, quantity, and size.
Uses of Sieve Shakers
Sieve shakers come in various types, including tapping type, horizontal vibration type, motor-driven type, and electromagnetic drive type, each suited for specific vibration and drive requirements. Some models are even capable of sorting wet materials.
Available in a range of sizes, sieve shakers can accommodate large volumes of material, up to 20 kg, or handle small, minute samples on tabletop machines.
Common applications include:
- Separating minute samples for scientific research
- Sorting large quantities of materials in civil engineering and construction
- Classifying mixed and varied waste materials
Principle of Sieve Shakers
Sieve shakers operate by stacking sieves of different sizes and vibrating them to sort materials according to grain size. The drive systems mainly include motor-driven and electromagnetic-driven types.
The choice of sieve type, size, and capacity depends on the specific materials and intended use. Additionally, the direction of vibration varies, with options like horizontal vibration and vertical tapping types available.
Large, motor-driven sieves are typically used for sorting materials in civil engineering, while smaller, tabletop electromagnetic-driven tapping sieves are more common in scientific research for sorting smaller samples. For wet materials, horizontal rotating types are preferred.
