Abstract

A compact modular mobile aggregate processing system configured with no stand-alone inter-plant conveyors for decreasing the footprint of the system and an infinitely adjustable flow diverter(s) for increasing the control of and variation of output characteristics of the system; the system further including specialized folding conveyors.

First claim

We claim:

1. A sliding swing gate blending assembly comprising:
a chute for receiving aggregate material therein; and
an adjustable diverter gate comprising:
a pivoting gate which is configured to block a first passage while permitting aggregate material to flow through a second passage; and
said pivoting gate is configured to translate across an area below said chute such that translation of said gate, results in an adjustable percentage of permissible flow through said first passage and said second passage.

2. The sliding swing gate blending assembly of claim 1 wherein said pivoting gate:
a. is coupled to;
b. is centrally located between; and
c. is configured to translate with; a fixed backflow directing plate and a fixed forward flow directing plate.

3. The sliding swing gate blending assembly of claim 2 wherein said chute has a predetermined fixed chute exit opening size and a predetermined chute material throughput capacity.

4. The sliding swing gate blending assembly of claim 3 wherein pivoting gate has a sliding swing gate entrance opening size at least half of said predetermined fixed chute exit opening size.

5. The sliding swing gate blending assembly of claim 3 wherein said pivoting gate has a sliding swing gate entrance opening size equal to half of said fixed chute exit opening size.

6. The sliding swing gate assembly of claim 3 wherein said pivoting gate has a sliding swing gate material throughput capacity configured to accommodate half said predetermined chute material throughput capacity.

7. The sliding swing gate assembly of claim 3 wherein said pivoting gate has a sliding swing gate material throughput capacity equal to half said predetermined chute material throughput capacity.

8. The sliding swing gate assembly of claim 7 further comprising a forward flow exit chute and a backward flow exit chute each of which is sized, configured and located to receive all material passing through said pivoting gate and an additional amount of material equal to said sliding swing gate throughput capacity.

9. A method of blending aggregate material comprising the steps of:
providing a mobile aggregate processing plant, configured to couple at one end to a semi-tractor and having at least four wheels at an opposite end;
providing, on said mobile aggregate processing plant, a swing gate adjacent to a first flow diverter directed toward a first exit chute; and
translating said swing gate in a direction toward said first flow diverter and thereby causing a reduction of material flowing through said first exit chute.

10. The method of claim 9 further comprising the steps of:
providing a second flow diverter directed toward a second exit chute; and
continuing to translate said swing gate in said direction toward said first flow diverter and thereby causing an increase of material flowing through said second exit chute.

11. The method of claim 10 further comprising the steps of:
providing a chute for receiving aggregate material therein; and
continuing to translate said swing gate toward said first flow diverter until an equal amount of material is flowing through said first exit chute and said second exit chute.

12. The method of claim 11 further comprising the steps of:
manipulating said swing gate to further increase a flow rate through said second exit chute, without translating said swing gate toward said first flow diverter.

13. The method of claim 12 wherein said step of manipulating said swing gate is accomplished by swinging said swing gate in a direction from diverting all material through said first exit chute toward diverting material through said second exit chute.

14. A mobile aggregate processing plant comprising:
a mobile aggregate processing plant, configured to be coupled at one end to a semi-tractor and having at least four wheels at an opposite end with thereon a sliding swing gate blending assembly for blending aggregate material having:
a chute for receiving aggregate material therein;
a gate which is configured to selectively block a first passage while permitting aggregate material to flow through a second passage;
said gate is configured to move with respect to an area below said chute such that movement of said gate, results in an adjustable percentage of permissible flow through said first passage and said second passage; and
wherein said gate is coupled to, is located between, and is configured to move with; a fixed backflow directing member and a fixed forward flow directing member.

15. The sliding swing gate blending assembly of claim 14 wherein said chute has a predetermined fixed chute exit opening size and a predetermined chute material throughput capacity.

16. The sliding swing gate blending assembly of claim 15 wherein said gate has a gate entrance opening size at least half of said predetermined fixed chute exit opening size.

17. The sliding swing gate blending assembly of claim 14 wherein said gate has a gate entrance opening size equal to half of said predetermined fixed chute exit opening size.

18. The sliding swing gate blending assembly of claim 14 wherein said gate has a gate material throughput capacity configured to accommodate half said predetermined chute material throughput capacity.

19. The sliding swing gate blending assembly of claim 14 wherein said gate has a gate material throughput capacity equal to half said predetermined chute material throughput capacity.

20. The sliding swing gate blending assembly of claim 19 wherein:
said gate is configured to move in a non-rotational manner with respect to an area below said chute such that such moving of said gate, results in an adjustable percentage of permissible flow through said first passage and said second passage.
