Among the figure, transmission grinding axle 1, grinding outer ring 2, grinding outer ring 3, frame 4, control system 5, hydraulic system 6, charging aperture 7, transmission and bracing or strutting arrangement 8, feed cavity 9, discharge chamber 10, upper cover plate 11.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Form by transmission grinding axle 1, grinding outer ring 2,3, frame 4, control system 5, hydraulic system 6, charging aperture 7, transmission and bracing or strutting arrangement 8, feed cavity 9, discharge chamber 10 etc. referring to the single-drive roll type pulverizing mill shown in Fig. 1-4.
Two grinding outer rings 2,3 are installed in above the slide rail of frame 4, and transmission grinding axle 1 is installed in two grinding outer rings 2, between 3, and the hydraulic cylinder of hydraulic system 6 is installed in the both sides of frame, and the piston rod of hydraulic cylinder links to each other with the end face of grinding outer ring 2,3.The distance measuring sensor of control system 5 is installed on the frame 4; Be used for measuring the horizontal displacement of grinding outer ring; Result through measuring adjusts hydraulic system, keeps the transmission grinding axle 1 of grinding machine and the relative position of grinding outer ring 2,3, avoids transmission grinding axle 1 too to tilt.
The cross section of transmission grinding axle 1 is circular, and 2,3 surfaces, two grinding outer rings then are the arcs that certain curvature is arranged.Referring to Fig. 4, along clockwise direction, constitute feed cavity 9 the grinding outer ring inner surface to the distance of grinding axis from large to small, the inner surface of the grinding outer ring in formation discharge chamber 10 changes from small to big to the distance of grinding axis.Therefore the cross section of feed cavity is exactly the little shape of a kind of outside big the inside of size size.This kind architectural feature makes closely knit that material can nature in grinding process, discharges contained gas in the material, and the vibration of grinding machine and noise are controlled effectively.Two feed cavity 9, two discharge chambeies 10 all become axial symmetry with the grinding axis.
