Additive Powder Vibrating Screen

Additive Powder Vibrating Screen are primarily used for impurity removal, grading, filtration, and particle size detection of additive powders, effectively solving problems such as powder agglomeration, sticking to the screen, and high precision requirements. Available in 304 and 316 stainless steel, this machine boasts excellent corrosion resistance, wear resistance, and hygiene. It can accommodate up to 5 screens for multi-stage sorting with a single feed, simultaneously separating coarse and fine powders and removing impurities. Designed for small-batch, multi-batch production, it can process small quantities of material in 5-10 minutes. Customization is supported, and it is compatible with 220V household power. An explosion-proof motor is available as an option. The machine model, screen mesh size, discharge port height, and sealing structure can be tailored to material characteristics, production volume, and installation space requirements.

What are the advantages of the Additive Powder Vibrating Screen?

The Additive Powder Vibrating Screen offers several outstanding advantages, meeting the high-standard sieving needs of the chemical, food, and pharmaceutical industries for fine powders. Its fully enclosed design eliminates dust, leakage, and environmental pollution, while protecting materials from external impurities. Made of stainless steel, it is corrosion-resistant, wear-resistant, easy to clean, and has a longer service life. The equipment boasts stable operation, low noise, and high screening accuracy. For special powders with poor flowability or strong corrosiveness, an ultrasonic system can be added to prevent clogging, or 316L stainless steel can be used for enhanced corrosion resistance. Details such as the inlet/outlet can also be adjusted according to process requirements to ensure perfect integration into the production line.

Additive Powder Vibrating Screen Types

Our factory produces two types of Additive Powder Vibrating Screens: ultrasonic and conventional. We can select the appropriate model based on the characteristics and mesh size of the additive powder to ensure accurate screening.

Vibrating Screen: Suitable for screening, removing impurities, and classifying most common additive powders. The equipment has a mature structure and stable operation. It can be used with multi-layer screens to screen additive powders with good flowability.

Ultrasonic Vibrating Screen: Based on a conventional vibrating screen, an ultrasonic system is added. It is specifically designed for ultrafine, easily agglomerated, and easily electrostatically adsorbed high-precision additive powders. The ultrasonic waves effectively break up powder agglomerates and prevent screen clogging, significantly improving the screening accuracy and throughput of fine powders, resulting in cleaner and more efficient screening.

Additive Powder Vibrating Screen Structure

The Additive Powder Vibrating Screen's structural design mainly consists of a screen frame and screen mesh. The screen frame is typically made of high-quality stainless steel, with multiple layers of screen mesh of different mesh sizes inside for graded filtration of materials. A vibrating motor, serving as the power source, is installed at the bottom of the machine. Adjustment of the eccentric weights at its upper and lower ends generates three-dimensional motion in horizontal, vertical, and inclined directions. A vibration damping spring system effectively isolates vibration, ensuring smooth operation and low noise. The dust cover and inlet/outlet are connected with quick-release clamps for easy disassembly and cleaning, and its fully enclosed structure effectively prevents dust leakage.

Additive Powder Vibrating Screen Technical Parameters

How Does the Additive Powder Vibrating Screen Work?

The Additive Powder Vibrating Screen's working principle is based on a clever combination of three-dimensional vibration and multi-layer grading. The vertical vibrating motor at the bottom is the power core, with eccentric weights installed at its upper and lower ends. When the motor operates, the excitation force generated by the upper and lower weights is superimposed in the horizontal, vertical, and inclined directions, driving the entire screen box to produce a precise three-dimensional rotary vibration motion. Under the combined force of this process, the additive powder fed onto the screen is thrown up and forms a spiral-shaped flow. During this motion, fine powder smaller than the screen mesh size passes smoothly through the screen surface and falls to the lower layer, becoming the undersize; while coarse particles or impurities larger than the mesh size continue to move forward along the screen surface and are eventually discharged from the discharge port.

What mesh size of additive powder can the Additive Powder Vibrating Screen screen sieve?

Our factory's Additive Powder Vibrating Screen can fully meet the sieving requirements of 500-mesh ultrafine powders. When processing ultrafine powders of 500 mesh and above, due to the fine particle size, light specific gravity, and susceptibility to electrostatic adsorption or agglomeration, ordinary vibrating screens may face problems such as screen clogging and reduced screen permeability. In this case, an ultrasonic vibrating screen becomes the ideal solution—it adds an ultrasonic system to the standard model, generating a high-frequency, low-amplitude vibration of 38kHz to effectively break the adsorption force and surface tension between the powder particles, keeping the screen clear.

Additive Powder Vibrating Screen Customer Case

A chemical company, primarily producing food and industrial additives, has long faced challenges such as the agglomeration of ultrafine powders, easy clogging of screens, and insufficient screening accuracy. They commissioned a custom-made 304 stainless steel, 800mm diameter additive powder vibrating screen. Featuring a fully enclosed structure and a 3-layer grading design, it effectively solves the problems of dust and material contamination. The equipment can quickly complete impurity removal and grading, easily screening 500 kg per hour, with stable operation and convenient screen replacement. After implementation, screening efficiency and finished product purity have significantly improved, meeting high-standard production requirements.
