There are various classification standards for vibrating screens. According to the material, there are mainly stainless steel and carbon steel vibrating screens. This article mainly introduces vibrating screens from the perspective of the appearance and shape of vibrating screens.
1. Rotary vibrating screen
Is a common type of vibrating screen, Rotary vibrating screen is usually selected for the following applications:
Remove lumps from products
Removal of packaging debris and other contaminants
Make sure no eggs get into the final product
Classify the product into layers with different granularity and size
Quickly remove insoluble in all kinds of slurries
Overall, the Rotary vibrating screen is used to ensure a higher quality of the final product. While the Rotary vibrating screen can be placed anywhere on the production line, in most production environments the Rotary vibrating screen is either the first machine in the process, preventing contamination, or the last machine before the packaging machine, for final quality inspection. Depending on the material, bouncing balls and ultrasonic cleaning devices can be selected to solve the problem of network blocking caused by factors such as high water content and strong viscosity of the material.
2. Linear Vibrating Screen
Linear Vibrating Screens, as the name suggests, they move products in a linear direction, so using a rectangular screen gives the product more time to pass through the grid, Linear Vibrating Screens, in addition to sorting and cleaning products, can also efficiently transport products, sometimes Used in place of traditional product conveyors as the vibration of the Linear Vibrating Screen gently bounces the product forward.
The Linear Vibrating Screen is particularly suitable for dry powdered or granular materials, and products with a high proportion of oversized particles, as its length allows fine products the opportunity to separate from larger particles and fall into the screen. This makes the Linear Vibrating Screen particularly suitable for dusting or dehydrating operations, such as removing small loose crumbs and flour from finished biscuits.
3. Airflow screening machine
The Airflow screening machine uses a set of paddles to push product out of a screen cylinder, spinning them at high speed and applying centrifugal force to the product. The cylinder is mounted horizontally so a slight twist is applied to the paddle to move the product down the length of the cylinder and the paddle is fed at a steady rate using an auger.
These paddles force product through the screens, giving them a higher throughput than vibrating screens. The motion of the rotating auger and paddle assembly has the added benefit of breaking up clumps or separating compacted products.
