Salt comes in many forms including salt for consumption (table salt), or salt that is used to de-ice roads (rock salt). When it comes to screening salt, rates and efficiencies are the key factors. Often times, companies in the salt industry need rates of over 100 tons an hour without compromising their ability to get an effective cut. Traditional shaker screeners have been used for these applications for years, but they have proven ineffective in lower micron ranges. The uneven dispersion of energy across the screen that is used with a flat shaker screener causes differences in efficiencies throughout the multiple decks on the machines. Often times with these screeners, the lower decks don’t receive nearly enough energy and this causes blinding. Near sized particles tend to get lodged in the screen when processing salt and this can cause production slow down.
