Salt Classifying with Vibro Sifter

What is a salt classifying with vibro sifter?

Salt classifying with vibro sifter refers to the process of using multiple layers of screens and specific mesh numbers to accurately classify raw salt according to particle size. According to the physical properties of different types of salt (such as table salt, sea salt, industrial salt), select the appropriate screen configuration, such as 20 mesh, 40 mesh, 60 mesh, 80 mesh, etc., to achieve effective separation of coarse salt, standard particle size salt and fine salt. The vibrating screen uses high-frequency vibration to make salt particles quickly pass through or stay in the corresponding screen layer, thereby achieving the purpose of particle size classification. It is suitable for multiple production links such as salt making, pre-packaging screening, impurity removal, etc.

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?

Salt particles vary greatly in size and are prone to absorbing moisture and clumping, requiring high hygiene standards. The screening process can also corrode equipment, making ordinary screening equipment unsuitable. Therefore, vibrating screens are chosen for salt grading. Vibrating screens operate through high-frequency or linear vibration, separating table salt and industrial salt into different particle sizes, removing impurities, breaking up clumps, and screening out dust, resulting in better finished product quality and smoother production. Vibrating screens are typically multi-layered with large screen sizes, such as 600mm, 1000mm, and 1500mm, which are common. They can complete both coarse and fine screening in one pass, processing more material per unit time. Material passes quickly through the screen under high-speed vibration with a short residence time, keeping pace with the continuous production of table salt and industrial salt, meeting the high-requirement screening requirements of these materials.

Salt Classifying with Vibro Sifter Types

Different types of salt classification with vibrating screens have their own characteristics in screening. Linear vibrating screens are suitable for rapid coarse screening and medium-precision screening of table salt. They have a relatively large throughput and are suitable for sea salt and coarse salt with similar particle size and smooth flow. During operation, the vibration force carries the salt particles in a straight line along the screen surface, preventing the material from piling up and the screen from clogging, resulting in a smoother screening process. Circular vibrating screens are more suitable for fine salt and powdered salt. The salt particles are tossed on the screen surface, allowing fine particles to pass through the screen better, resulting in more uniform salt particle size. They are often used for screening food-grade fine salt. Ultrasonic vibrating screens add high-frequency ultrasonic vibration to ordinary vibration, which can reduce the sticking of salt particles and screen clogging. They can also screen salt with high moisture content smoothly and are often used in industrial salt and refined salt applications where high screening requirements are required.

How Salt Classifying with Vibro Sifter Works

The material is fed evenly through the inlet and undergoes projectile and diffusion motion under the high-frequency vibration of the screen. Fine salt particles rapidly pass through the screen apertures under the action of gravity and centrifugal force, becoming qualified undersize material; coarse particles and agglomerates are blocked by the screen and separated and discharged as oversize material. For highly adhesive agglomerated salt, the vibration can break up the agglomerates, exposing their true particle size. Lightweight foreign matter such as plastic fibers float to the surface during vibration due to density differences and are collected and removed at the discharge end.

What can the salt classifying with vibro sifter be used for?

Salt classification with Vibro Sifter is used in both crude and refined salt production. In crude salt production, vibrating sieves perform preliminary screening, removing large impurities such as stones, grass roots, and plant residues, and separating the salt according to particle size. In the refined salt stage, it performs grading based on particle size. For applications requiring specific salt particle size, such as food-grade and industrial-grade salt, multiple layers of sieves can be used to separate several different coarse grades of salt at once. Coarse salt is typically screened using 20-60 mesh sieves to remove large impurities and allow large salt particles to pass through smoothly. Refined salt grading commonly uses 80-120 mesh sieves, with high-quality food-grade refined salt using 150-200 mesh sieves, and specialized industries like pharmaceuticals using 300 mesh and finer sieves. In humid environments, salt treated with fine sieves disperses small particles, reducing moisture absorption and clumping.

Application scenarios of vibrating screens in the field of salt screening

Salt Classifying with Vibro Sifter is widely used in the field of salt screening. In the production of table salt, the vibrating screen quickly separates coarse salt, fine salt and ultrafine salt through screens of different mesh sizes to ensure that the particle size of the finished salt is uniform; at the same time, it can remove impurities in the raw materials and improve the purity of the salt. In industrial salt processing, the vibrating screen can quickly screen large-particle salt to meet the specific requirements of chemical, metallurgical and other industries for salt particle size. Its high-frequency vibration design avoids salt particles clogging the mesh holes, and with anti-corrosion materials (such as stainless steel or plastic coating), it can adapt to high humidity and high salt corrosion environments. In addition, the vibrating screen is also used for the final screening of salt before packaging to ensure that no agglomerated salt enters the market, significantly improving production efficiency and product quality.

Salt classifying with vibro sifte price

The price of salt classifying with vibro sifter varies greatly due to different models, materials, mesh size and functional configurations. When purchasing, you need to pay attention not only to the applicability of the equipment and the subsequent maintenance costs, but also to comprehensively consider your actual needs, equipment quality, performance, after-sales service and other factors, so as to choose a product with high cost performance.

Salt Classifying with Vibro Sifter Case

Vibrating screens are widely used in the classification and screening of salt. According to the different particle sizes, they are divided into coarse salt, fine salt, ultrafine salt, dry salt and wet salt. Generally, the mesh size of coarse salt is 10-30, and linear vibrating screen is often used for preliminary screening; the mesh size of fine salt is 40-100, and rotary vibrating screen (three-dimensional vibrating screen) is suitable; the mesh size of ultrafine salt is 100-400 or above, and ultrasonic vibrating screen can be used; dry salt (extremely low moisture content) can use all types of vibrating screens; wet salt (high moisture content, easy to agglomerate) is suitable for dehydration vibrating screen or centrifugal screen. The following are the mesh size ranges of various types of salt and the applicable screening equipment:
