    Soft Rock Minerals. The KDS Micronex™ excels in grinding soft rock minerals into fine particle size. It is able to process limestone gypsum zeolite (clinoptilolite) glacial clay and other soft-rock minerals and can turn them into fine dry powders. Generally the KDS Micronex can produce particle sizes of less than 75 microns (below 200 mesh) at a production rate 2-3 tons per hour.
