Introduction of Vibrating Sieve Machine

Vibrating Sieve Machine

Vibrating sieve machine, also called sieve machine, capable of simple safety sieving and precise classification of powders or granules, removes oversized contaminants from products, accurately separates products into 2-6 different sizes, sieves Score up to 500 meshes. The material is separated by a wire mesh, so that smaller particles pass through different mesh widths and larger particles pass through different mesh openings. The separation of large particles can also remove any impurities in the material, and through powerful three-dimensional motion (horizontal, vertical and tilting), the processing capacity is doubled to four times that of conventional machines.

types of vibrating sieve machine

The Vibrating sieve machine allows up to 5 sieves to separate up to 6 different sizes of products, possible diameters: 400, 600, 800, 1000, 1200, 1500, 1800mm, suitable for sieving from 36 microns to 25 mm . A throughput of 100 to 5,000kg/h is allowed, depending on the product, mesh size and feed flow of the machine.

Ultrasonic Vibrating Screen

It is an ultrasonic system added on the basis of ordinary vibrating sieve. It consists of a generator and a probe. The ultrasonic frequency is applied to the sieve, which can prevent the sieve from being blocked and can be accurately separated to 20µm (#635mesh).

Application of Vibrating Sieve Machine

1. Removal of impurities: high fluidity powder processing, fast removal of large particles or fine powder with low content.

2. Grading and screening: Continuously select mixed materials of different particle sizes and classify them into different particle size grades. Can be divided into one, two, three, four and so on. What's more, only one operation can continuously filter up to 5 stages of product separation.

3. Solid-liquid separation: quickly remove insoluble solids in various slurries, and remove unqualified impurities or suspended solids in slurries.

Working Priciple of Vibrating Sieve Machine

According to different screening requirements, through 1-5 layers of screens with different mesh numbers, in the process, the bouncing balls under each layer of screens continuously hit the screens, so that the materials are smoothly screened and effectively prevent the materials from clogging the screen holes. The material (fine material) close to the screen hole falls under the screen through the screen, and the material (coarse material) larger than the screen hole size stays on the screen surface and is discharged from the discharge port.

Structure of Vibrating Sieve Machine

Vibrating sieve machine is composed of dust cover, sieve frame, screen mesh, mesh rack, mesh cleaning device, motor (vibration source), shock absorbing spring, base and other parts.

Dust cover: It is composed of feed inlet and inclined cone, and its lower end is connected with the screen frame to prevent workshop dust from falling into the material when the vibrating screen is working. Commonly used materials are stainless steel, carbon steel and plastic. And so on 3 kinds of materials.

Screen frame: It is rolled and welded by steel plate, with bearing rings at the upper and lower ends, and flange rings inside the lower part, which are used to fix the structure of the screen members.

Vibration motor: vertical vibration motor, divided into four specifications: 2, 4, 6, 8, and horizontal. The vibration times are 2870, 1460, 980, and 740RPM respectively. It can be designed as an explosion-proof type (inflammable and explosive occasions)

Screen mesh: models include φ600, 800, 1000, 1200, 1500, 1800, etc., and materials include stainless steel, carbon steel, and plastic.

Cleaning device: clean the clogged materials in the screen mesh to increase the output. It is available in silicone and rubber. You can also choose an ultrasonic cleaning device (635 mesh fine powder with static electricity).

Shock-absorbing springs: There are 12-20 vibration-isolation springs along the vibration transmission body. The base is welded from steel coils. There are access doors and electrical switch housings on the bottom wall. An annular flange is welded on the upper part of the base wall, and the flange is connected with the vibration transmitting body through a vibration isolation spring.

Additional options

1. Blinding system: you can choose bouncing ball (commonly used particles, powder type below 100 mesh), brush (suitable for spherical materials and crystalline products), ultrasonic deblinding system (suitable for viscous, precise ultra-fine powder), Enables sieving of powders on sieves as fine as 20 microns without clogging or clogging.

2. Sieve deck lift system: Using two high performance pneumatic piston assemblies, multiple sieve decks can be quickly and safely lifted to a height for comfortable access to the sieve decks that need to be inspected or replaced.

3. Quick Release Clamp: An innovative quick release clamp that provides consistent and even clamping pressure. It overcomes the problems associated with frequent readjustment of the lower clamp, providing benefits such as extended life of clamp pads, seals and gaskets, as well as minimizing heat generation and damage to the mating surfaces of the vibrating sieve.

4. Magnetic Separator: Designed to provide the ultimate solution for iron contamination control when inspecting and screening dry powders, it features a unique open design for easy and efficient removal of iron contamination.
