This disclosure relates to apparatus which is particularly adapted for forming an admixture of dry materials, such as a first sound deadening, heat resistant and fire insulating fibrous material, such as paper, and a second material which makes flame resistant, such as powdered boric acid, the apparatus including conveyor means for conveying the first dry material between input and discharge points along a path of travel established by the conveyor means, means for detecting the amount of the first dry material being conveyed, means responsive to the detecting means for feeding the second dry material to the conveying means in proportion to the amount of the first dry material detected by the detecting means, and comminuting means at the discharge point for receiving the first and second materials and comminuting the same into a homogeneous admixture. The detecting means are preferably weighing means, means for imparting motion to the conveyor means, and the responsive means function further for controlling the motion imparting means to vary the speed of movement of the conveyor means in proportion to the amount of the first dry material detected by the detecting means.
Apparatus particularly adapted for forming an admixture of dry materials comprising conveyor means for conveying a first dry material between input and discharge points along a path of travel established by said conveyor means, means for detecting the amount of the first dry material being conveyed by said conveying means, means responsive to said detecting means for feeding a second dry material to said conveying means in proportion to the amount of the first dry material detected by said detecting means, and comminuting means at said discharge point for receiving said first and second material for comminuting the same into homogeneous admixture, said comminuting means including a chamber, a rotatable comminating member in said chamber for comminuting the first and second materials and moving the same between inlet and outlet ends of said chamber, an outlet opening in said outlet end for discharging therethrough the homogeneous admixture, a filter downstream of said outlet opening, and suction means downstream of said filter for drawing air from said chamber through said outlet, to augment the movement of the first and second materials from said inlet end toward said outlet end.
