Crushing reduces the material to the desired size, screening separates it into the correct fractions, and feeders evenly dose the material to the next process stage. We design each solution according to the material being processed and the customer's process, ensuring reliable long-term operation of the entire system.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<section id=\"business-card-block_d2f5ea00878c46eb8d40cf5d972f59a8\" class=\"business-card default\" >\n\t<div class=\"tag\">Interested?

Typical applications include waste heat boiler slag, agglomerated metallurgical dusts, and bottom ash. The crushers can withstand continuous wear and temperatures of up to 300\u00b0C.<\/p>\n\n\n<div class=\"wp-block-list__container va-container\">\n<ul class=\"wp-block-list\">\n<li><strong>Rotor crushers<\/strong> suitable for the primary crushing of coarser material.<\/li>\n\n\n\n<li><strong>Roll crushers<\/strong> are a choice for fine crushing when accurate control of the final product size distribution is desired.<\/li>\n<\/ul>\n<\/div>\n\n\n<p>By combining crushing types, the desired particle size distribution is achieved from coarse feed to fine end product.

The type of screen is always selected based on the properties of the material to be processed, the required capacity and the desired end result.
