Salt Classifying with Vibro Sifter

What is a salt classifying with vibro sifter

Salt has the characteristics of strong hygroscopicity and easy agglomeration, and the particle size requirements of industrial salt and edible salt are very different. Salt classifying with vibro sifter solves these problems by adapting to sieves of different meshes. For example, 80-120 mesh sieves are often used to screen edible salt, which can obtain fine and uniform particles; 20-40 mesh sieves are suitable for coarse screening of industrial salt to remove larger impurities.

Why choose a salt classifying with vibro sifter?

The salt classifying with vibro sifter is chosen because salt materials have special process requirements such as large particle size differences, easy moisture absorption and agglomeration, high hygiene requirements, and easy corrosion of equipment during the screening process, which are difficult to meet with ordinary screening equipment. The salt classifying with vibro sifter can efficiently achieve the classification, impurity removal, block breaking and dust removal of table salt, industrial salt, etc. through high-frequency vibration or linear vibration, improving product quality and production efficiency.

salt classifying with vibro sifters usually adopt a multi-layer design and a large-diameter screen surface (such as 600mm, 1000mm, 1500mm, etc.), which can complete coarse screening and fine screening at one time, greatly improving the processing volume per unit time, and are suitable for screening scenes of materials such as table salt and industrial salt with strong continuity and high demand. Its high-speed vibration drives the material to pass through the screen quickly, reducing the material retention time and effectively improving the overall production capacity.

Types of salt classifying with vibro sifters

Linear vibrating screens are suitable for rapid coarse screening and medium-precision screening of salt. It has a large processing capacity and is suitable for salt with relatively uniform particles and good fluidity, such as sea salt and coarse salt. 

The linear vibrating screen uses vibration force to cause salt particles to move linearly along the screen surface, reducing material accumulation and blockage, and improving screening efficiency. Circular vibrating screens are suitable for screening salt materials with high particle fineness such as fine salt and powder salt. Its screening action causes the salt particles to do a throwing motion on the screen surface, which is conducive to the screening of fine particles and improves the screening accuracy. The circular vibrating screen is suitable for the fine screening of food-grade salt to ensure the uniform particle size of the product.

The ultrasonic vibrating screen combines the mechanical vibration of the traditional vibrating screen with the ultrasonic high-frequency vibration, which can effectively prevent the adhesion between salt particles and the clogging of the screen. It is particularly suitable for the screening of wet salt or salt with high water content. The addition of ultrasonic waves improves the screening ability and screening efficiency of the screen, and is suitable for industrial salt and refined salt with extremely high screening accuracy requirements.

What can the salt classifying with vibro sifter be used for

In the production process of crude salt, the salt classifying with vibro sifter can be used for preliminary screening to remove larger impurities such as stones, plant residues, etc., and classify the crude salt by size. For refined salt after processing, the salt classifying with vibro sifter can accurately classify according to the particle size. For example, in application scenarios such as food-grade salt and industrial salt that have specific requirements for particle size, the salt classifying with vibro sifter can be installed with multiple layers of screens as needed to complete the screening tasks of multiple particle size levels at one time.

Coarse salt screening: Usually a screen between 20 and 60 mesh is selected to effectively remove larger impurities and allow larger salt particles to pass through.

Refined salt grading: If it is refined salt for general food processing or industrial use, a screen of 80 to 120 mesh is required. For food-grade refined salt with higher requirements, a screen of 150 to 200 mesh is used. In some special applications, such as the pharmaceutical industry, a screen with a higher mesh number (such as 300 mesh or more) is required.

Moisture-proof and anti-caking treatment: Salt products used in humid environments are sometimes treated with finer screens to prevent agglomeration, which helps to disperse small particles that are easy to absorb moisture.
