Reduction of ore size at the first stage of grinding at concentration plants

The use of Kroosh screens is the least expensive way of reducing the ore size down to 0-8 mm before feeding to the mills at the first stage of grinding. This operation improves the performance of grinding equipment by 15-20% and significantly reduces power consumption for ore grinding, which makes up about 40% of the total power consumption at concentration plants.


Improved accuracy of separation of polydisperse concentrates at the first and second stages of wet grinding

The application of multifrequency screens instead of hydrocyclones increases the accuracy of the polydisperse concentrates separation with a corresponding increase of productivity of ball mills and reduction of power consumption.


Reduction of sintered ore size at crushing and screening plants

The use of Kroosh screens at the final sorting of mine ore is the best solution for obtaining high-quality sintered ore with particle size less than 10 mm.


Optimization of coal charge composition in metallurgical coke production

Effective fine screening of coal charge with high adhesion and a moisture content of up to 12% increases the extraction of 0-6 mm product 4-5 times.


Increased screening efficiency in metallurgical limestone flux production

Kroosh screens allow "dry" production of high-quality 5-20 mm metallurgical flux from wet crushed limestone with a twofold specific capacity of the equipment.


Reduced losses and improved quality of the product in the extraction of uranium by the borehole method

Desliming and dewatering on a multifrequency screen makes it possible to obtain pure product at a specific capacity of 30-35 m³/m²∙h with an S:L ratio of 4:1, which is unattainable on other equipment.
