Concepts of a Vibrating Screen: A Vibrating Screen or just screen is created using vibrating chassis that supports the interior or other surfaces and screening elements. The vibrating screens are widely used to classify diverse particles by sizing, starting from bulk products in a consistent process. The raw products or inlet materials advance from the surface where screens are installed to the opposite end. The final particles are released as per their shape, size, and density by the screens.
The Vibrating Screen Manufacturers also design screens loaded by the centre, and raw particles move fundamentally to outputs fed on the periphery. The process must be consistent for correct advancement of the inlet materials, and it is caused by the vibration of the screen surface horizontally. There are also screens designed with a specific inclination and the advanced movement of the inlet materials depending on the machine’s vibration and gravity.
Elements of Vibrating Screens
The screening elements of the Vibrating Screen are either slightly curved or flat surfaces with perforations for a particular size so that when inlet materials are poured in bulk on the screening element, it passes the particles smaller than the size of perforations.
The screening elements used in the screens are either nylon wire mesh or metal wire mesh. Bars are also used to pass the inlet materials between the elements. Metal sheets with hexagonal, square, or circular perforations are used along with rigid polyurethane or rubber sheets.
The types of screening elements are selected based on the application of the screens, size and shape of the inlet particles, nature of products, temperature, humidity, and adhesion. You may contact the Microwiremesh Manufacturers in India to make the right choice of screening elements.
Screening Efficiency with Vibrating Screens
The traditional non-vibrating screens comprise of fixed mesh that has lots of inclinations. As the vibration is introduced, the machine starts shaking, and particles jump instead of advancing or sliding to the screening surfaces. The jump is to allow the particles to pass through the hole, and it happens efficiently when the machine vibrates powerfully.
When the particles jump and fall back to the screen, it passes through the wire mesh screening element. Since some of the particles can bypass the method, no screen can guarantee 100% efficiency as it needs infinite numbers of vibrations and jumps so that particles can pass through the holes.
Hopefully, the concept of Vibrating Screen efficiency is clear. It is the percentage by weight of inlet particles that filter through the holes divided by the number of particles that must be screened.
What is the Production Capacity of a Vibrating Screen?
The production capacity of the screens depends on the size of the screening surface of the screen. The more quantity of inlet particles you intent to screen, the more surface your machine must-have. Over time the screen becomes small to classify a large number of particles, and it starts reducing the efficiency of the screening. It avoids fitting a large number of particles through its holes.
So, the screen’s production capacity depends on the screen’s size, and you must contact the Vibrating Screen Manufacturers to learn the suitable size for the inlet particles you intend to classify.
Vibration Frequency in the Vibrating Screens
As the general thumb rule for the large classifications, large vibration amplitudes and low frequencies are necessary. However, for fine classifications, smaller amplitudes and high frequencies are important.
If the inlet particles are large, a wide and slow movement is best as it gives the particles the required vibration and jumps. If the particles are smaller, it is best to lower the jumps and vibration for better screening.
The Good and Bad Vibrating Screen
The good Vibrating Screen is reliable and reduces maintenance and wear. It comes with strong vibration, and the higher vibration ensures better jumps for the particles in the screening process. It delivers more efficiency and production.
The bad screens are not at all reliable and appropriate to use for screening. The particles stick to the wire screens, and it reduces the efficiency of the machine.
It would be best if you always prefer buying the vibrating screens from reliable Microwiremesh Manufacturers in India. They supply good screens and elements to heighten the raw materials’ classification process and enhance the overall performance of the machine.
