Rotary Vibrating Screen

Rotary vibrating screen

What is a rotary vibrating screen

The rotary vibrating screen is a kind of screening equipment. It can integrate the three functions of impurity removal, classification and filtration. It is specially used to process materials such as dry and wet powders and granules, and its processing range is in the range of 0 to 500 mesh. It also has the ability to filter slurry. The slurry range of this filtration is 0 to 600 mesh. In 2025, rotary vibrating screens are more common on the market, and their prices range from 3,500 yuan to 38,000 yuan per unit. The specific amount is determined based on the model and material.

Its working principle is to use a vibration motor to generate three-dimensional vibration, causing the material to jump on the screen surface, thereby achieving screening. This equipment can use 1 to 5 layers of screens at the same time. Most manufacturers provide different specifications starting with a diameter of 400 mm.

Core application scenarios

In the food industry, such as flour mills or condiment workshops, rotary vibrating screens are used to remove agglomerates from powders and extract impurities. In 2025, a food factory in Guangdong will use a stainless steel rotary vibrating screen to screen 200-mesh starch. The processing capacity can reach 100 kilograms per hour, and the powder will not fly, and the workshop environment will be clean.

In the pharmaceutical industry, rotary vibrating screens are often used to filter traditional Chinese medicine powder or raw materials. There is a pharmaceutical company that uses a rotary vibrating screen made of plastic material to process acidic slurry, and sets the mesh size of the screen to 100 meshes. This rotary vibrating screen can ensure that the liquid will not leak. It is also resistant to strong acid corrosion and fully complies with GMP production requirements.

Material and model selection

Rotary vibrating screens are divided into three types based on materials: carbon steel structure, stainless steel structure and plastic structure. Carbon steel structure is suitable for ordinary industrial materials. Its price is the lowest. The screen frame of vibrating screen is riveted and processed to prevent cracking , which is about 3,500 yuan. Stainless steel structure is used in fields including the food and pharmaceutical industries. Materials such as 304 or 316L are corrosion-resistant and easy to clean, and the price is around 15,000 yuan.

Plastic material specially used to deal with strong acid and alkali environments, such as the kind used to deal with electroplating waste liquid in chemical plants. As for the screen frame of the vibrating screen, the screen frame is riveted and welded to prevent cracking . It is made of polypropylene and will not rust. In terms of models, the diameters are in the range of 400 mm to 1500 mm and are not identical. Customers can choose according to the output and the number of screen layers, and the manufacturer will provide one-on-one shopping guide services.

special function version

The gate type rotary vibrating screen is suitable for materials that need to be controlled for screening time, such as ceramic powder. During operation, the gate is closed to allow the material to stay on the screen surface for twenty to thirty seconds to improve the screening accuracy. The edge type is used for liquid materials such as paint, and the edge is raised to prevent splashing and thereby avoid waste.

The most expensive version is the ultrasonic rotary vibrating screen, with an approximate price of 38,000 yuan. This screen type is mainly used to solve the problem of material agglomeration and blockage. For example, when screening 325-mesh ultra-fine silica powder, the ultrasonic generator will produce high-frequency vibration, which will destroy the electrostatic adsorption between the powders. In the end, the screen will not be clogged and the output will remain stable.

Daily use and maintenance

When installing the rotary vibrating screen, make sure the ground is flat and use expansion bolts to fix the shock-absorbing springs. Before starting, check whether the screen is tensioned and whether the mesh number is correct. You can choose from 2 mesh to 500 mesh. Every time you replace the screen, you must clean up the residue on the sealing ring.

Check the vibration motor temperature every day to see if it exceeds 75 degrees. This is routine maintenance. The inside of the screen frame must be cleaned every week, either by blowing with clean water or compressed air. A chemical factory in Zhejiang gave feedback in 2026. The plastic rotary vibrating screen in their factory was used for 8 months in the past, and the screen was replaced once during this period, but the overall operation has been relatively stable.

Purchasing and Service Advice

When purchasing and selecting, you must first confirm the characteristics of the material, whether it is in a dry powder state or a slurry state, whether it has corrosive characteristics, and what the required fineness is. Just like the alumina powder that has been screened to 400 mesh, it is recommended to use the stainless steel ultrasonic type. The direct sales model from the manufacturer generally covers the service of delivering the goods to the required location, with a shelf life of one year, and free debugging of screen specifications.

It is suggested to the customer that samples should be sent to the manufacturer for trial screening first, and the factory's testing equipment should be used to confirm the output and accuracy. For example, a 100-mesh screen can process hundreds of kilograms of material per hour. The actual data is based on the test sieving report. After delivery, engineers will be on site to guide installation and operation.
