The U.S. currently has the second largest construction market across the globe, with expenditures exceeding $900 billion. Though the industry as a whole is easy to analyze, there are plenty of important smaller aspects of the construction market that require much more detailed attention.

Crushing operations, for instance, utilizing screening bars and all sorts of tools and materials to get major tasks finished. If you’re involved in any crushing operation project for a construction company, you might want to consider figuring out how to increase your screening bar efficiency. Here are a few ways to increase screening efficiency within these major projects.

Increasing speed

Although it would be convenient to simply crank up the screening and crushing speed as much as possible, it wouldn’t solve everything and could even result in additional problems. That’s why increasing the screening speed is only a part of improving the efficiency. Faster speeds will certainly decrease the death of bed during the process, which is good, but it also will increase the G-force, which decreasing its bearing life. Doing both increasing your speed and opening the screen a little bit should help improve overall efficiency during the causing process.

Use higher quality materials

Rather than using old, feeble, low quality crushing bars and screens during the process, consider upgrading your materials. By using quality grizzly bars for screening and crushing jobs, you’ll be able to handle much more difficult tasks and your equipment will last much longer.

Rotation direction

Changing the rotation can drastically improve your screen’s performance. Running the process against the flow or uphill, for example, can increase the material retention time and action on the screen, subsequently providing the particles more openings within the screen.

Varying stroke

Depending on the type of material being transferred, the stroke should be adjusted accordingly. When dealing with fine separation, for example, you should be using higher speeds and less stroke. Consequently, coarse separation requires increased stroke and slower speeds.

Increasing the angle of inclination

Using tipping grids to increase the inclination angle will result in significantly faster material travel. As long as you’re being careful and not overdoing it, your material should be able to travel at these steeper angles in dry screening applications. Be careful not to increase the incline too much because the roll over time could result in materials missing openings.
