Screening medium to coarse-grained bulk materials (5.0 mm to 100 mm) is done by circular vibrating screens, also known as Circular vibrating screen. For circular vibrating screens to function, the screen mesh is indirectly excited. Unbalanced masses cause a circular vibrating motion in the entire screen frame.

Rectangular Vibrating Screen Characteristics
Rectangular vibrating screen come in various models and configurations to meet virtually every screening, dewatering, classification, or scalping need.
Stainless steel mesh, nylon or synthetic fabric, bar screen, or wedge wire dewatering panels are some other materials found in screens.
Screen fabric is chosen for longer durability and is set up for easy maintenance and replacement. Carbon steel, corrosion-resistant stainless steel, or another lined media can be used for Vibrating compaction table contact surfaces, depending on the quality of the screened bulk material.
Screen bodies can either be open, exposing the processed material or closed, preventing dust from escaping.
A cassette of bouncing balls can be arranged to lessen screen cloth choking caused by sticky materials.
 
Screeners that are either round or mechanical, or rectangular:
One of the three most common screener shapes is a rectangular shape. These machines are a great all-around option compared to circular screeners, which are more space-efficient but usually more expensive, and mechanical screeners, which are easier to use but less successful at fine-separating and sieving chores.
 
When deciding on a screener, it's important to think about the following:
Needs in Manufacturing: 
A good screener consistently and successfully separates or screens out the target material. To maximize productivity, you should invest in machines that can perform many functions.
Footprint: 
A compact machine has many advantages in crowded manufacturing facilities. However, smaller devices are limited in the material they can process simultaneously. A machine with a larger footprint could be preferable if production volumes are high.
Maintenance: 
Most screeners need help to function properly during maintenance, reducing your efficiency. If downtime is not an option, a machine with easily accessible parts and minimal moving parts may be the best buy.
Safety: 
Pharmaceutical and chemical manufacturing are only two examples of industries where screening for safety is a top priority. You can install ventilation hoods on many screeners to keep your team safe when working with potentially dangerous chemicals.
 
How to Use a Rectangular Vibrating Screen:
The screen frame vibrates straight or linearly because the motors are mounted at right angles. Because of this, larger particles are efficiently conveyed forward even when the screen's frame is tilted upward. The structure of the rectangular screen can be tilted downward at an angle that best suits the intended use. The machine's capacity is maximized in the uphill position, leading to a pool at the feed end. The water pressure in the pool causes the fluid to spread more. The large particles are efficiently transported by the screen frame's horizontal Vibrating table screens and released outside the pool area.

Conclusion:
Buying powder materials in bulk can save businesses a lot of money and boost output at powder processing facilities. However, powder processing companies must invest in a bulk bag unloader system to collect the product and dispense it into the processing line to take advantage of all this and more.
