A new technology for forming multilayer mineral-wool mats by zig-zag pendulum layering of the primary mineral mat is described. It consists in forming variable-height loops in the primary mineral-wool mat in order to equalize the feed rate of the primary mineral-wool mat to the pendulum layering device and the circular velocity of the pendulum at the point of egress from it of the primary mineral-wool mat over the entire extent of the zig-zag layering pattern of the primary mat. Analytical formulas are given for calculating the parameters of the technology implementing the new method of zig-zag pendulum layering of mineral-wool mats.

生产矿棉产品的新技术

描述了一种通过初级矿物垫的之字形摆成层形成多层矿物羊毛垫的新技术。其目的在于在初级矿棉垫中形成高度可变的环，以使初级矿棉垫向摆式分层装置的进料速率和摆锤从其出来的点处的圆周速度相等。在主要垫子的锯齿状分层样式的整个范围内，使用主要矿物棉垫子。给出了计算公式，以计算实现矿棉垫曲折摆新方法的技术参数。
