Vibrating Sieve for Powder

What is Vibrating Sieve for Powder?

Vibrating Sieve for Powder is commonly used for powder classification and screening. It uses a vibrating motor to generate excitation force, causing powder materials to be thrown up and moved forward on the screen surface, thereby achieving separation of different particle sizes. The screening mesh size is usually 20-500 mesh, and the output is 0.1-20 tons/hour. The equipment has the characteristics of high screening accuracy, good sealing, easy cleaning, and multi-layer screening.

Vibrating sieve for powder is a special term for the screening of powder materials in various industries. In order to maintain the accuracy, the powder will be screened. For example, the powder in the pharmaceutical and food industries needs to be isolated from external pollution, and the chemical and metallurgical industries need to prevent material It can be seen that the sealing treatment of the vibrating sieve for powder equipment must be in place. How to achieve the sealing treatment?

Material and model specifications of vibrating sieve for powder

The vibrating screen for powder comes in three material combinations. The first is made of stainless steel for the parts in contact with the material, with a carbon steel bottom cylinder. The second is made entirely of stainless steel, including the bottom cylinder. The third is made of carbon steel for all components, including the parts in contact with the material. For materials that corrode stainless steel, Dahan Machinery offers a plastic vibrating screen with a frame diameter between 600 and 1800 mm. It can be equipped with 1 to 3 layers of screens for multi-stage screening, allowing you to choose the appropriate model based on your needs.

Vibrating Sieve for Powder Classification

Vibrating screens for powder are divided into stainless steel vibrating screens and ultrasonic vibrating screens. These two types of vibrating screens are classified according to different principles, focusing on specific application areas and core advantages.

The stainless steel type, primarily manufactured from stainless steel, offers advantages in corrosion resistance and hygiene, preventing chemical reactions between powder and metal, while facilitating easy cleaning and disinfection. It is used in industries such as food and pharmaceuticals, where material hygiene requirements are stringent, such as flour screening and pharmaceutical powder grading.

The ultrasonic type integrates an ultrasonic system on top of traditional vibrating screening. Its core function is to address the problems of fine and sticky powders prone to agglomeration and screen clogging. High-frequency ultrasonic vibrations break down powder agglomerates, improving screening efficiency and accuracy. It is particularly suitable for ultrafine powder screening in the chemical and new energy sectors, such as the fine screening of lithium battery material powders and coating powders.

Advantages of Using a Vibrating Sieve for Powder

The Vibrating Sieve for Powder uses high-frequency vibration to rapidly separate powder particles, capable of separating powders of varying particle sizes. This increases throughput by 30%-50% compared to traditional screening equipment. The equipment precisely controls powder particle size, capable of separating fine powders down to 20 microns. Most equipment is constructed of stainless steel, offering a smooth, easy-to-clean surface. The simple design allows for easy assembly and disassembly, minimizing the risk of residual contamination. The vibrating motor drive system offers low energy consumption, low noise, and a low failure rate, enabling continuous operation for extended periods of time and minimizing production interruptions.

Recommended mesh size for Vibrating Sieve for Powder

When using a Vibrating Sieve for Powder, the appropriate sieve size (10-400 mesh) can be selected based on the particle size and sieving requirements of the material. Fine powders are generally sieved using 100-400 mesh sieves, suitable for sieving and classifying fine powders to ensure more uniform particle size and fineness. Medium-sized powders can be sieved using 40-100 mesh sieves to process medium-sized powders, removing impurities and ensuring more stable product quality. Coarse powders can be sieved using 10-40 mesh sieves to separate larger particles, resulting in a more uniform finished product. When dealing with mixed powders, different mesh sizes can be used to classify the powder according to actual particle size requirements, achieving the desired sieving results.

Sealing device for vibrating sieve for powder

The vibrating screen for powder consists of multiple components, and gaps between these components are inevitable. Jinhe vibrating screens use rubber or silicone rubber sealing strips for sealing, and flexible connectors can be used at the inlet and outlet, connected and sealed via a connecting cylinder. Vibrating screens used for powders must be equipped with a dust cover. To facilitate observation of the material screening process, please ensure that an observation port is provided on the dust cover when purchasing. Another factor is the position of the springs. For example, medical vibrating screens require an apron, which covers the springs as well. This effectively prevents dust from accumulating on the vibrating motor for extended periods, thus extending the motor's lifespan, although the appearance may be affected.

Cleaning device for vibrating sieve for powder

Powder particles of varying sizes can easily clog the sieve openings. Therefore, the Vibrating Sieve for Powder installs rubber or silicone elastic balls between the frame and the sieve. These balls bounce and impact the sieve under vibration, achieving effective cleaning. Furthermore, some powders are static-prone, easily absorb moisture and clump, contain oil, or have excessively fine particle sizes; for these, an ultrasonic vibrating sieve is recommended. For example, powders such as sulfur powder and polyvinyl alcohol are explosive. Be sure to inform the sales staff of these properties when purchasing. To avoid danger, it is recommended to use an explosion-proof vibrating sieve, i.e., replace the vibrating sieve motor with an explosion-proof motor.

Precautions for using Vibrating Sieve for Powder

When using a vibrating screen for powder, pay attention to the characteristics of the material and the production output. Some powders are sticky, prone to static electricity, or have ultrafine particles; these materials can be used with an ultrasonic vibrating screen. During production, ordinary powder vibrating screens have a larger processing capacity, while rotary vibrating screens perform better in terms of sieving fineness, although their output will be lower. When selecting equipment, users can consider the type of powder, the required fineness, and the hourly output to determine the appropriate model and configuration.
