The invention relates to the crushing equipment. A lining of rattler contains plates connected along the drum and made from elastomeric material. The upper parts of the plates form wave working surface of lining and they are equipped with partially vulcanized metallic pins. The lower parts of the plates have adjusting reinforcement and are connected by means of fastening elements with the drum of mill. The upper parts of each plate have a form of trapezoid, whose front, middle and back edges form a sinusoid wave working surface of lining. In this case metallic pins are executed in the form of parallelepipeds vulcanized into said front and middle faces of plates are located at sharp angle to the axis of drum. Moreover, along the perimeter of the vulcanized part of pins the grooves filled with elastomeric material of plates are made. The invention provides increase of the output of mill, decrease of the mass of lining, and also increase of the period of service life of rattler. |
