Definitions
- the present invention relates to a mineral breaker-feed apparatus.
- a breaker-feed apparatus is usually sited near to the location whereat the mineral is won and is used for receiving the freshly won mineral and delivering it to a conveying system which conveys the mineral away to a desired location.
- the breaker-feed apparatus usually attempts to provide two basic tunctions, viz. (a) break down oversized pieces of mineral which could otherwise cause blockage problems in the conveying system and (b) provide a regularised flow of mineral into the conveying system, thereby isolating the conveying system from surges or intermittent deposits of mineral.
- a breaker-feed apparatus has usually included a storage or hopper compartment into which the freshly won mineral is deposited and a conveyor which moves the mineral out ot the storage compartment to a discharge location whereat it is deposited onto a take-away conveyor which forms part ot the conveying system.
- a breaker drum is usually sited above the conveyor at a suitable position upstream from the discharge location so that oversized mineral being conveyed by the conveyor is subjected to a breaking operation.
- a breaker-feed apparatus including a mineral inlet compartment having a mineral sizer which breaks mineral to a desired size, feed means for feeding the broken material into a storage compartment, the storage compartment including conveyor means for moving the broken material from the storage compartment to a discharge station.
- Figure 1 is a side view of an embodiment according to the present invention
- Figure 2 is a plan view of the embodiment shown in Figure 1;
- Figure 3 is a sectional view taken along line A-A in Figure 1;
- Figure 4 is a sectional view taken along line C-C in Figure 1;
- Figure 5 is a sectional view taken along line B-B in Figure 1.
- Figure 6 is a side view of another embodiment according to the present invention
- Figure 7 is a plan view of the embodiment shown in Figure 6.
- Figure 8 is an illustration of a screw conveyor.
- Apparatus according to the present invention is generally shown at 10 and includes three distinct sections, a mineral inlet section or compartment 12, a mineral storage section or compartment 14 and a mineral discharge section or station 16; the three sections being located in succession and joined together to make a single composite unit.
- a conveyor 20 powered by a hydraulic motor 21 is provided which passes in succession through sections 12, 14 and 16, the upper run 20a ot the conveyor defining the base of each section.
- the direction of movement of the upper run of the conveyor is from right to left as viewed in Figure 1 so that mineral may be conveyed thereby in succession through sections 12, 14 and 16.
- the conveyor illustrated has individual flights 20b interconnected by chains 20c and provides a positive feed conveyor. It will be appreciated that other types of teed conveyor may be provided if desired.
- the mineral inlet section 12 there is provided a pair ot mineral breaker drums 25 which are positioned above the conveyor 20.
- the upper run of the conveyor torms the base ot the section and the drums are mounted so that their axes of rotation are substantially parallel to the path of travel of the conveyor.
- the breaker drums 25 are rotatably mounted in a housing 30 whicn has end wails 32 and inclined side walls 33.
- the side walls 33 are made up of panels 34 fabricated from steel plating and which are bolted together.
- the inner surface of end walls 32 and side walls 33 are defined by wear plates 35.
- the breaker drums 25 are rotated by a drive unit 36, the drive unit serving to rotate the breaker drums in opposite directions so that material deposited into the inlet section is directed between the drums and broken by the picks 40 mounted on each drum.
- Each drum 25 is provided with helical scrolls 42 and the picks 40 are mounted on the scrolls so that on rotation of the drums picks on one drum intermesh with picks on the other drum.
- the scrolls are designed so as to quickly move mineral which has passed between the drums into the mineral storage section 14. Accordingly mineral which has been broken by the drums is moved at a taster rate into the storage section 14 than the rate of travel of the conveyor 20.
- an opening 48 is provided which is of sufficient dimensions to enable the desired throughput to be handled.
- the conveyor 20 need not extend into the inlet section or may only extend partially into it since it is possible to rely solely on the breaker drums for moving material into the storage section, or other feed means.
- the storage section 14 includes inclined side walls 50 which torm a continuation from side walls 33 and which are composed of separate panels 52 which are fabricated from steel plate and bolted together. Accordingly, the length of the storage section 14 (and hence its holding capacity) can be easily varied by insertion or removal ot a desired number ot panels 52.
- the inside surface of walls 50 are defined by wear plates 53.
- the conveyor 20 extends into the discharge section 16 and terminates at a sprocket assembly 80.
- the sprocket assembly 80 is driven by the hydraulic motor 21 and in turn drives the conveyor 20.
- the upper run 2 ⁇ a_ ot the conveyor torms the base of the discharge section and it is arranged to form an inclined base so that the terminal end ot the conveyor may be positioned above a take away conveyor so that material passing through the discharge section is moved up the incline to be deposited onto the take away conveyor.
- the steepness of the incline of the base of the discharge section may be selected in order to create a "boiling effect" in the material being conveyed up the incline ( i . e . some of the material falls back down the incline) so as to help regulation ot discharge of material Irom the discharge section.
- the storage section 14 is partitioned from the discharge section 16 by a movable partition 60 which can be raised or lowered as desired.
- the movable partition 60 therefore serves as a means ot control of mineral being discharged from the storage section 14.
- the partition can be used to prevent flow of mineral out of the storage section 14 in which case if mineral is still being deposited in the inlet section 12 mineral would build up behind the partition and would continue to build up progressively toward the entrance to the storage section 14.
- feed means for moving the broken mineral into the storage compartment may comprise the breaker drums alone or a combination of the breaker drums and the conveyor 20.
- the feed means may include a screw conveyor which is located beneath the breaker drums and arranged to feed the broken mineral through said opening 48.
- the use of such a conveyor enables other types ot breaker drums to be used.
- PCT Patent Application W0 83/00318 illustrates a screw conveyor posiitioned beneath breaker drums.
- Figure 8 For the purposes of illustration only Figure 1 ot PCT Patent Application WO 83/00318 is reproduced herein as Figure 8.
- the apparatus is provided with means tor moving the apparatus over ground.
- the illustrated embodiment is provided with wheels 70 which are preferably driven by a hydraulic motor 71 and are steerable.
- the apparatus is therefore selt propelled and steerable.
- the wheels 70 are mounted on the storage section.
- the inlet section preterably includes support means which as illustrated is in the torm ot a base portion 12a_ which is arranged to contact the ground. Accordingly, the weight of material being deposited into the inlet section is distributed between the portion 12a and wheels 70.
- the support means may be in the form of retractable support members so that during movement ot the unit the support means may be retracted.
- FIG. 6 and 7 An alternative embodiment is illustrated in Figures 6 and 7.
- the embodiment shown in Figures 6 and 7 has many similarities to the embodiment described with reference to Figures 1 to 5 and accordingly similiar parts have been designated by similar reference numerals.
- the breaker drums 25 are mounted in the inlet section 12 so that their axes of rotation are inclined to the direction of travel of the upper run 20a of conveyor 20.
- the inclination of the drums is such that they are spaced further above the upper runs 20a at the discharge end of the inlet section 12. This is desirable as it enables a greater height of material to be discharged from the inlet section and into the storage section 14.
- the side walls 33 extend rearwardly of the breaker drums to terminate approximately directly above the rearmost end of the casing 101 housing the rearmost sprocket assembly 100 of the conveyor 20.
- the uppermost edge 33a of each side wall is conveniently inclined so as to be parallel with the inclined axes ot the drums and is preferably arranged so as to be level with the uppermost path ot travel ot the picks protruding from the drums.
- Advantageously removable side walls 110 are provided which serve to define a hopper for feeding material to the breaker drums 25.
- the motor 36 for driving the drums is located so as to extend along the outside of one of the side walls and drives the drums through a gear box 36a.
- continuous tracks 120 are provided for moving the entire unit over ground.
- the motive power unit 121 tor driving the pair of continuous tracks 120 is conveniently mounted to extend along the outside and beneath the opposite side wall 33 under which motor 36 is mounted.
