Abstract

Abstract A briquetting arrangement in which two wheels in opposed relation rotate in opposite directions and have die members mounted about the peripheries thereof with cavities formed in the die members in which material fed between the rotating wheels is compacted into briquettes. The die members are formed of a hard wear resistant material such as cemented tungsten carbide and are detachably mounted on supporting block members which are, in turn, fixed to the peripheries of the respective wheels.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 340 words
In a briquetting machine; a wheel comprising a main body part mounted for rotation on a central axis, radially outwardly opening axially extending pockets which are V-shaped in cross section formed in the periphery of said body part in circumferentially adjacent relation, support blocks having radially inner sides complementary in shape to said pockets and seated in said pockets, the opposite ends of each block being closely adjacent the ends of the blocks next adjacent thereto, each block having radially outwardly facing shoulders formed thereon at the opposite axial ends and each shoulder extending the full length of the respective block, flange means on the axial ends of the body part each having a radially inwardly facing shoulder on the axially inner side engaging the adjacent shoulders on said blocks and clamping the blocks in the respective pockets, at least one flange means being detachable from said body part for releasing said blocks from said pockets, each block having a groove formed in the radially outer side with a bottom wall and side walls, the said grooves in said blocks being in aligned end to end relation and forming a continuous annular recess about the wheel, a corresponding side wall of each groove inclining toward the other side wall in the radially outward direction, a die member of hard wear resistant material in each groove having recess means formed in the radially outer side, each die member having a radially inner side resting on the bottom wall of the groove in the respective block and one axial side which is inclined correspondingly to and in engagement with the inclined side wall of the respective groove, the other axial side of said die member being axially spaced from the other side wall of the groove and diverging therefrom in the radially outward direction, and a bar-like wedge member about the same length as said die member wedged between said other side of the die member and said other side wall of said groove and clamping said die member in said groove.
Claim 2
Dependent Claim 340 words
In a briquetting machine; a wheel comprising a main body part mounted for rotation on a central axis, radially outwardly opening axially extending pockets which are V-shaped in cross section formed in the periphery of said body part in circumferentially adjacent relation, support blocks having radially inner sides complementary in shape to said pockets and seated in said pockets, the opposite ends of each block being closely adjacent the ends of the blocks next adjacent thereto, each block having radially outwardly facing shoulders formed thereon at the opposite axial ends and each shoulder extending the full length of the respective block, flange means on the axial ends of the body part each having a radially inwardly facing shoulder on the axially inner side engaging the adjacent shoulders on said blocks and clamping the blocks in the respective pockets, at least one flange means being detachable from said body part for releasing said blocks from said pockets, each block having a groove formed in the radially outer side with a bottom wall and side walls, the said grooves in said blocks being in aligned end to end relation and forming a continuous annular recess about the wheel, a corresponding side wall of each groove inclining toward the other side wall in the radially outward direction, a die member of hard wear resistant material in each groove having recess means formed in the radially outer side, each die member having a radially inner side resting on the bottom wall of the groove in the respective block and one axial side which is inclined correspondingly to and in engagement with the inclined side wall of the respective groove, the other axial side of said die member being axially spaced from the other side wall of the groove and diverging therefrom in the radially outward direction, and a bar-like wedge member about the same length as said die member wedged between said other side of the die member and said other side wall of said groove and clamping said die member in said groove.
Claim 3
Dependent Claim 38 words
A briquetting machine according to claim 1 in which each said shoulder is concentric with the central axis of said wheel whereby the shoulders on said flange means take a full bearing on the shoulders on said blocks.
Claim 4
Dependent Claim 23 words
A briquetting machine acCording to claim 1 in which the said shoulders are inclined so as to converge in the radially outward direction.
Claim 5
Dependent Claim 31 words
A briquetting machine according to claim 1 which includes screw means extending through each wedge member and threadedly engaging the respective block for clamping the wedge member to the respective block.
Claim 6
Dependent Claim 27 words
A briquetting machine according to claim 1 in which both axial sides of each said die member incline toward the other thereof in the radially outward direction.
Claim 7
Dependent Claim 18 words
A briquetting machine according to claim 1 in which each said die member comprises cemented hard metal carbide.
Claim 8
Dependent Claim 17 words
A briquetting machine according to claim 1 in which each said die member comprises cemented tungsten carbide.
Claim 9
Dependent Claim 45 words
A briquetting machine according to claim 1 in which the bottom wall of each said groove and the opposed radially inner side of the respective die member are planar and perpendicular to a radius of the wheel passing through the center of the respective block.
Claim 10
Dependent Claim 42 words
A briquetting machine according to claim 1 in which the bottom wall of each said groove and the opposed radially inner side of the respective die member are curved so as to be concentric with the axis of rotation of said wheel.
