Abstract
Abstract A machine for the treatment of material, for example for the size reduction of solid materials, comprises carrier means for supporting the material and means for suspending and positively driving the carrier means so as to vibrate the latter at a fixed amplitude and frequency. A plurality of the carrier means is provided, suspended and positively driven in such manner that the two or more carrier means and driving means are inherently balanced.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
96 words
A machine for the treatment of material, comprising a supporting structure, a plurality of carrier means for supporting the material to be treated, said carrier means being disposed outside said structure laterally thereof, and driving means comprising a crankshaft extending longitudinally within the structure, connecting rods engaging the crankshaft, and slide members mounted for linear reciprocatory motion in bearings laterally of said structure, the connecting rods being coupled to the respective ones of said carrier means through said slide members and the arrangement being such that said carrier means and driving means produce a balanced arrangement.
Claim 2
Dependent Claim
96 words
A machine for the treatment of material, comprising a supporting structure, a plurality of carrier means for supporting the material to be treated, said carrier means being disposed outside said structure laterally thereof, and driving means comprising a crankshaft extending longitudinally within the structure, connecting rods engaging the crankshaft, and slide members mounted for linear reciprocatory motion in bearings laterally of said structure, the connecting rods being coupled to the respective ones of said carrier means through said slide members and the arrangement being such that said carrier means and driving means produce a balanced arrangement.
Claim 3
Dependent Claim
73 words
A machine according to claim 1, wherein the carrier means are vibratory and a series of the vibratory carrier means is provided and arranged with an outlet of one carrier means in close proximity to and connected with an inlet of another carrier means of the series, the arrangement being such that the material to be treated passes from one to another carrier means of the series to receive progressive or staged treatment.
Claim 4
Dependent Claim
34 words
A machine according to claim 1 and intended for the comminution of material, wherein the carrier means comprise a grinding chamber for containing the material to be comminuted, with or without other grinding media.
Claim 5
Dependent Claim
43 words
A machine according to claim 2, wherein there are two series of the vibratory carrier means and the driving means vibrate the carrier means of each series substantially in phase with one another and substantially in anti-phase with those of the other series.
Claim 6
Dependent Claim
19 words
A machine according to claim 1, wherein the carrier means are supported cantilever fashion by the respective slide members.
Claim 7
Dependent Claim
28 words
A machine according to claim 1, comprising at least one pair of carrier means disposed on opposite sides of the structure, the carrier means being vibrated in anti-phase.
Claim 8
Dependent Claim
59 words
A machine according to claim 1, wherein the structure comprises a closed casing providing an oil reservoir with splash lubrication of the driving means housed within the casing, the casing having side walls through which the slide members project and providing said bearings therefor and end walls between which the crankshaft extends and which provide bearings for the crankshaft.
Claim 9
Dependent Claim
38 words
A machine according to claim 7, wherein one of said end walls has an external mounting for an electric driving motor so that the motor can be coupled directly to the crankshaft to provide a self-contained balanced machine.
Claim 10
Dependent Claim
52 words
A machine according to claim 2, wherein the carrier means comprise grinding chambers each having an inlet and an outlet disposed transversely of the direction of vibration, the grinding chambers being connected by tubular couplings such that they form therewith a tube or conduit along which the material to be treated passes.
Claim 11
Dependent Claim
48 words
A machine according to claim 9, wherein the grinding chambers are provided with grinding media which are of different sizes as between one grinding chamber and another of the series, such that a progressive or staged size reduction of the material results as it passes along the conduit.
