近十几年来,国内分级破碎机发展十分迅速,该设备所体现出的强制破碎、过粉碎率低、振动小、严格保证出料粒度、产生粉尘少、可靠性高等诸多技术进步,逐步为整个行业所认可,很多单位及选煤研究院所部已经充分认识到这一点,并积极将这一新技术应用于煤炭及其它行业中。分级破碎机作为洗选准备系统的关键设备,一旦该设备出现问题,整个洗选系统将不能正常运行,只有充分认识和应用 Over the past decade or so, the grading crusher has been developing rapidly in China. The equipment has been characterized by forced crushing, low crushing rate, small vibration, strict grain size, less dust generation and high reliability. Recognized by the industry, many units and coal preparation institutes have fully realized this and actively applied this new technology to coal and other industries. Grading crusher as washing preparation preparation system of key equipment, once the equipment problems, the entire washing system will not be able to normal operation, only fully understand and application
