    • An adjustable screen apparatus for a material destruction device includes a first stationary fixed member and a second member positioned in an operatively juxtaposed and nesting relationship for reciprocal movement relative to the first member, each having a predetermined plurality of openings which are disposed in a predetermined pattern. A guide system is provided for guiding the reciprocal movement of the second member relative to the first member. A power operated drive is coupled to a source of power and to the second member for reciprocally moving the second member between a first position wherein each opening in the second member substantially overlaps a respective opening in the first member for producing large size particles and a second position wherein each opening in the second member partially overlaps each of a pair of adjacently disposed openings in the first member for producing small size particles.
    • 一种用于材料破坏装置的可调式筛网装置包括第一固定固定件和第二件,该第二固定件和第二件以相对于第一部件相互往复运动的方式并置和嵌套,并具有预定的多个开口, 。 引导系统用于引导第二构件相对于第一构件的往复移动。 动力驱动的驱动器联接到动力源并且连接到第二构件,用于在第一位置之间往复移动第二构件,其中第二构件中的每个开口基本上与第一构件中的相应开口重叠以产生大尺寸的颗粒, 位置,其中第二构件中的每个开口部分地与第一构件中的一对相邻设置的开口中的每一个重叠,以产生小尺寸的颗粒。
