摘 要
低的破碎比和高的磨损率是与传统的破碎机相联系的篅@＜牧礁鎏匦浴Ｒ蛭獾悖诳笫砹鞒痰挠τ弥校苌倏悸堑剿牵⑶液雎粤撕芏嗨堑挠诺恪１疚拿枋隽艘桓鲆驯环⒄蛊鹄吹男掠钡亩怨跗扑榛荚谔岢稣庑┞鄣恪Ｗ魑狽CRC,这种新式破碎机结合了两个辊筒，它们由一个交替布置的平面和一个凸的或者凹的表面组成。这种独特的辊筒外形提高了啮合角，使NCRC可以达到比传统辊式破碎机更高的破碎比。用一个模型样机做的试验表明：即使对于非常硬的矿石，破碎比任可以超过10。另外，既然在NCRC的破碎处理中结合了辊式和颚式破碎机的作用，那就有一种可能：那种新的轮廓会带来辊子磨损率的降低。

ABSTRACT
Low reduction ratios and high wear rates are the two characteristics most commonly associated with conventional roll crushers. Because of this, roll crushers are not often considered Jor use in mineral processing circuits, and many of their advantages are being largely overlooked. This paper describes a novel roll crusher that has been developed in order to address these issues.Referred to as the NCRC (Non-Cylindrical Roll Crusher), the new crusher incorporates two rolls comprised of an alternating arrangement of plane and convex or concave surfaces. These unique roll profiles improve the angle of nip, enabling the NCRC to achieve higher reduction ratios than conventional roll crushers. Tests with a model prototype have indicated thar even for very hard ores, reduction ratios exceeding l0:l can be attained. In addition, since the comminution process in the NCRC combines the actions of roll and jaw crushers there is a possibility O' that the new profiles may lead to reduced roll wear rates. © 2001 Elsevier Science Ltd.
