摘 要
低的破碎比和高的磨損率是與傳統(tǒng)的破碎機相聯(lián)系的篅@＜牧礁鎏匭浴Ｒ蛭獾?，哉N笫砹鞒痰撓τ彌校萇倏悸塹剿牽⑶液雎粵撕芏嗨塹撓諾?。本文描孰h艘桓鲆馴環(huán)⒄蠱鵠吹男掠鋇畝怨跗撲榛莢諤岢穌廡┞鄣?。作为NCRC,這種新式破碎機結合了兩個輥筒，它們由一個交替布置的平面和一個凸的或者凹的表面組成。這種獨特的輥筒外形提高了嚙合角，使NCRC可以達到比傳統(tǒng)輥式破碎機更高的破碎比。用一個模型樣機做的試驗表明：即使對于非常硬的礦石，破碎比任可以超過10。另外，既然在NCRC的破碎處理中結合了輥式和顎式破碎機的作用，那就有一種可能：那種新的輪廓會帶來輥子磨損率的降低。

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.
