Genom vridning ay handtaget 42 kan matningscylinderns tapp 12 antingen fastlasas eller frigiyas relativt hylsan 11. Verkningssattet harvid torde utan vidare fOrklaring framgfi ay fig. VI och VIII. As previously stated, the grinding cylinder 1 has a pin 12, which is inserted into the cylindrical sleeve 11 on the shaft housing 10 and is secured to it by means of a welding means. A guide glue 35, which is screwed into the front of the sleeve 11, extends into a hollow 36 in the adjacent surface of the grinding cylinder, so that it is inclined at the steering wheel in relation to the shaft housing 10. The aforementioned welding means is provided with the curved surface 13. ay welding bolt 37, which Or is inserted into a hall 38, which Or drilled through a thickening on the upper side of the cylindrical sleeve 11. One end of the welding bolt 37 is formed into a lug 40, which fits into a threaded groove 41 in the spirit of the shaft-shaped portion ay a handle 42. A screw which is threaded through a hole in the handle 42 and screwed into the shaft ay the locking bolt 37, fixes the handle yid the hollow, which prevents Iran from moving axially by a screw 44, which engages in a pair of rings 451 welding bolts. A threaded pin 46 is inserted into the bottom of the ring ring 45 in such a position that it hits the screw when the lashing hole 37 is turned to the release position. By turning the handle 42, the pin 12 of the feed cylinder can either be welded or released relative to the sleeve 11. The mode of action here should be shown in Figs. VI and VIII without further explanation.

I de fiesta kottkvarnar upptages trycket ax matarskruyen ay en fiberbricka, som Or placerad mellan matarskruvens drivna ande och den angransande ytan ay malningscylindern. Enligt det p0 ritningarna yisade utforandet overfores matarskruyens andtryek Over drivaxeln till ett axialtryck upptagande lager i yaxelhuset. Harigenom mojliggores att en flans 47 pa matarskruven kan lost passa in i en ursyarvning 48 i malningscylindern 1. Likasa kan matarskruvens axe! 49 vara liist inpassad i den cylindriska tappen 12.

Denna luftstriimning forhindrar, att yakuum uppstar under nedre anden 19 ay kolven 18. Utan denna anordning skulle materialet tendera att tillsluta utrymmet omkring kolven och salunda n 0-enom alstrande ay vakuum forsvara manovreringen ay kolven. Mellanrummet mellan flansen 47 och urborrningen 48 Or, fastan del — —3 tillater luft att fritt passera, tillrSckligt litet ' for att kottdelar .ej skola kunna tranga igenom nagon h8gre grad. In most cone mills, the pressure is absorbed by the feed screw ay a washer, which Or is placed between the driven spirit of the feed screw and the adjacent surface of the grinding cylinder. According to the embodiment shown in the drawings, the pressure of the feed screw over the drive shaft is transferred to an axial pressure absorbing bearing in the shaft housing. This makes it possible for a flange 47 on the feed screw to fit loosely into an original inheritance 48 in the grinding cylinder 1. Likewise, the shaft of the feed screw can! 49 be liist fitted in the cylindrical pin 12. Through these loose passes air can circulate Iran the mill of the grinding cylinder 1 through the radial and axial gaps between Hansen 47 and the bottom of the ursyary ring 48 and along the shaft 49 into the cylindrical sleeve 11 provided by Or an airway 50, which communicates with the outside air. This air flow prevents the vacuum from rising under the lower spirit 19 of the piston 18. Without this device, the material would tend to close the space around the piston and thus, by generating a vacuum, defend the maneuvering of the piston. The gap between the flange 47 and the bore 48 Or, the fixed part - —3 allows air to pass freely, sufficiently small 'so that the cone parts will not be able to penetrate to any great extent.
