MIXER Russian patent published in 1995 - IPC

FIELD: manufacture of building materials. SUBSTANCE: mixer is made in the form of a truncated cone bunker mounted along the vertical line, with the vertex downwards. A mixing device is located inside the bunker. It consists of two mixing members: a helical one mounted on the drive shaft along the vertical line and an additional one in the form of a pug mill located along the generatrix of the mixer housing connected with the drive shaft with the aid of a pole and a supporting heel. The drive for the auger rotation is carried out by means of rolling out the bearing wheel fixed in the upper part of the auger along the inner surface of the cone housing. In order to change the rotational speed of the auger the bearing wheel is made with the possibility of shifting along the auger axle. The pole is telescopic, spring-loaded with the possibility of regulating the force of the spring compression. EFFECT: enhanced quality of mixing loose materials. 2 cl, 2 dwg
