MORTAR PRODUCTION PLANT Russian patent published in 2010 - IPC B28C5/20 

FIELD: process engineering.

SUBSTANCE: invention relates to devices intended for preparation of concrete and mortars. Proposed plant comprises housing equipped with drive and made up of elements to form plane-bounded outer and inner surfaces. Said housing represents broken spiral-shape tunnel with dash zigzag-like screw lines made along the tunnel edges and triangular flow cross section made by sections each being made from rectangle and two identical trapezoids with their lower bases equal to rectangle lateral side and upper bases equal to each other. Trapezoids lateral sides are equal to the other two sides of rectangle to form sections on the faces inclined in opposite directions and towards face hole section axis, said holes representing equilateral triangles. Every other section is turned relative to previous section through the angle corresponding to the turn of section to its one side so that sections axes are inclined to intersect. Aforesaid housing is mounted on the bed via frame with pneumatic cylinders.

EFFECT: expanded performances, higher intensity of preparation.
