克奈尔森(Knelson)选矿机是加拿大研制的回收金的离心选矿机。该机利用高重力“G”与独有的流态化作用相结合,可用于砂矿和硬岩,选别从-6毫米直至微粒金,有效回收游离的金颗粒。影响金回收的各种因素,包括水量、流态化压力和给矿速度诸操作参数。克奈尔森选矿机与其它各种重选机比较 Knelson concentrator is a reclaimed gold centrifugal concentrator developed in Canada. Combining high-gravity “G” with unique fluidization, this machine can be used for placer and hard rock, with sizes ranging from -6 mm up to particulate gold for efficient recovery of free gold particles. Various factors that affect gold recovery, including operating parameters such as water flow, fluidization pressure and feed rate.
