Abstract
Abstract ABSTRACT OF THE DISCLOSURE A crushing plant having a pair of elongated con-veyors, one over the other, which extend forwardly and upwardly under crusher means located forwardly adjacent to an input station at the rear of the plant, to different elevated discharge zones at the front of the plant. The upper conveyor receives crushed material discharging from the crusher means, and the lower conveyor receives input material of final product size sorted out in a material receiving and classifying unit at the input station. The conveyors can be arranged to discharge onto spaced upper and lower screen and transporting decks on a second crushing plant located ahead of the first, and having conveyor means cooperating with said lower conveyor to provide a final product conveyor extending the full length of both plants.

Total Claims: 19
Claim 1
Independent Claim
154 words
Elongated crushing apparatus having at its rear a vibratory receiving and classifying unit for input materials, and having a crushing station forwardly thereof; a pair of length-wise adjacent conveyors extending forwardly and upwardly beyond said crushing station and having lower portions which extend under said station; means comprising crusher means at said station, from which crushed materials issue to drop onto the lower portion of one of said conveyors to be delivered thereby to a high load discharge zone at the front of said apparatus; screen means on said vibratory for vibrationally conducting over size input materials forwardly to said crusher means, and a second screen member beneath the first screen member; and means beneath the second screen member for con-ducting final product size materials that pass therethrough onto the lower portion of the other of said conveyors to be delivered thereby to a high level discharge zone at the front of said apparatus.
Claim 2
Dependent Claim

Elongated crushing apparatus having at its rear a vibratory receiving and classifying unit for input materials, and having a crushing station forwardly thereof; a pair of length-wise adjacent conveyors extending forwardly and upwardly beyond said crushing station and having lower portions which extend under said station; means comprising crusher means at said station, from which crushed materials issue to drop onto the lower portion of one of said conveyors to be delivered thereby to a high load discharge zone at the front of said apparatus; screen means on said vibratory for vibrationally conducting over size input materials forwardly to said crusher means, and a second screen member beneath the first screen member; and means beneath the second screen member for con-ducting final product size materials that pass therethrough onto the lower portion of the other of said conveyors to be delivered thereby to a high level discharge zone at the front of said apparatus.
Claim 3
Dependent Claim
23 words
The crushing apparatus of claim 1,wherein said conveyers are mounted one over the other to thus comprise spaced apart upper and lower conveyors.
Claim 4
Dependent Claim
52 words
The crushing apparatus of claim 2, further charac-terized by: said last named means comprising a chute structure having its discharge end disposed over the receiving end of the lower conveyor; and means for collecting and conducting to said chute structure said materials which pass through the mesh of said second screen member.
Claim 5
Dependent Claim
36 words
The crushing apparatus of claim 3, further charac-terized by: said last named means comprising another conveyor, positioned beneath said second screen member to collect the material passing therethrough and discharge the same into said chute structure.
Claim 6
Dependent Claim
31 words
The crushing apparatus of claim 2, further charac-terized by means for conducting carryover materials from the forward end of said second screen member to the rear portion of the upper conveyor.
Claim 7
Dependent Claim
67 words
The crushing apparatus of claim 2, wherein said crusher means comprises first and second crushers; said first crusher receiving forwardly advanced carryover material from said first screen member and depositing materials crushed thereby onto the upper one of said conveyors; and said second crusher receiving forwardly advanced carryover materials from said second screen member and depositing materials crushed thereby onto the receiving end of the lower conveyor.
Claim 8
Dependent Claim
31 words
The crushing apparatus of claim 3, further charac-terized by chute means for conducting carryover materials from the forward end of said second screen member to said portion of the upper conveyor.
Claim 9
Dependent Claim
84 words
The crushing apparatus of claim 2, further charac-terized by said crusher means being mounted on the plant at a location directly ahead of said vibratory unit, and having a single outlet from which crushed materials issue; and an upright chute structure mounted on the apparatus at a location between the crusher means and said vibratory unit, for conducting to said portion of the upper conveyor carryover materials discharging from the forward end of said second screen member, in bypass relation to the crusher means.
Claim 10
Dependent Claim
130 words
The crushing apparatus of claim 2, further charac-terized by: an elongated material processing apparatus adjacent to the forward end of said crushing apparatus; a vibratory receiving and classifying unit on said processing apparatus comprising a screen deck at an upper level onto which said upper conveyor discharges, to vibrationally advance carryover materials thereon forwardly for further processing; means on said processing apparatus mounted under said screen deck to receive materials that pass therethrough together with materials that discharge from the forward end of said lower conveyor and to conduct such materials forwardly to a discharge zone; and a delivery conveyor on said processing apparatus, to receive materials from said discharge zone and to conduct the same forwardly and upwardly to a delivery zone at the front of said processing apparatus.
Claim 11
Dependent Claim
63 words
The crushing apparatus of claim 1, wherein said crusher means comprises a primary crusher to receive carryover materials from said first screen member and to deposit materials crushed thereby onto the upper one of said conveyors, and a secondary crusher to receive carryover materials from said second screen member and to deposit materials crushed thereby onto the receiving end of said lower conveyor.
Claim 12
Dependent Claim
38 words
The crushing apparatus of claim 1, further charac-terized by means for conducting carryover materials from the forward end of said lower screen member to the rear portion of the upper conveyor in bypass relation to the crusher means.
Claim 13
Dependent Claim
95 words
The crushing apparatus of claim 2, further charac-terized by: said conveyors extending forwardly and upwardly from a location forwardly adjacent to the receiving and classifying unit to delivery zones at different elevations at the front of the apparatus; means for conducting carryover materials from said second screen member to the rear portion of the upper conveyor; and said means beneath the second screen member comprising conveyor means to receive final product size materials that pass through said second screen and to conduct such final product size material to the receiving end of the lower conveyor.
Claim 14
Dependent Claim
