How YOU Can Save Money On Your Renovation

Pneumatic vibrators are indispensable in the material handling industries. They come in handy to ensure a smooth flow of materials. These highly-beneficial machines come in various forms to suit specific material handling needs. Generally, the direction of material flow will determine the most suitable vibrator. For instance, if you have materials flowing along a straight line, it would be best to go for a vibrator with linear vibration. If your material handling applications entail separating materials, sizing them, or removing unwanted materials from the rest, a vibrating screen will be necessary. However, vibrating screens also come in many options, and you will need these tips to narrow them down to the ideal one for your needs.

Consider the Screen's Eccentric Throw

A vibratory screen's eccentric throw refers to its radius, and it determines its level of aggressiveness. The kind of materials you are dealing with will help you select a vibratory screen with the right eccentric throw. For instance, if your application involves sifting materials, a vibratory screen with a small eccentric throw would be a perfect choice. The smaller the eccentric throw, the finer the separation will be. Therefore, evaluate your needs first and choose the eccentric throw that will be most suitable.

Assess the Screen Media

Vibratory screens come in a wide range of media, which affect their performance. The media are the screening surfaces and are usually made from various materials and have different designs. Your specific application will also help you to select the right one in this regard. For instance, woven wire cloths are some of the traditional screening media you will find. They are usually made of steel and have slotted or square openings to aid in material separation. Choose this media if you have applications such as sizing, dewatering, and scalping.

If you have wet applications, polyurethane media are the best option. The material is highly resilient when it comes to wet applications compared to other media. On the other hand, if you have some heavy-duty jobs that require materials to be pre-screened before being crushed, grizzly bars are the ideal solution. These screens are among the sturdiest options you will find and perform exceptionally well in wear resistance.

Think About Vibration Frequency

Vibration frequency is equally crucial. Low frequencies are usually best for large materials because they make it easier for the material to fall through easily without skipping many 'jump holes'.
