FIELD: process engineering.
SUBSTANCE: invention relates to machine building and can be used in agriculture for loose materials grinding. This grinder consists of the frame, main drive composed of motor and V-belt drive, flat crank, extra drive composed of motor and V-belt drive, outer and inner cones, loading and unloading bins. Inner cone rigid shaft is located inclined and engaged with the main drive shaft by cardan joint. Flat crank is engaged with extra drive and coupled with inner cone vertex. To comply with process requirements, said flat crank can be articulated with inner cone vertex or rigidly coupled therewith to make an integral closed kinematics. Angle between flat crank swivel axes and that of inner cone shaft inclination to vertical are equal. Note here that axes of flat crank swivels and those of cardan joint intersect in one point.
EFFECT: higher efficiency of grinding.
