Apparatuses and methods for the disbursement of relatively heavy materials, such as aggregate or wet compost out of a moveable container are provided. Material is conveyed within the container to a feeder that meters the material into an air stream. The air stream is provided at a relatively high pressure and flowrate with respect to other mobile blowing systems. The air stream carries the material though a hose that is manned by an operator. The operator points the hose towards a desired location for application of the dispersed material.

The invention is claimed as follows: 1. A method for low pressure dispersing of dense aggregate comprising the steps of: moving a container proximate to a destination, the container holding a bulk supply of aggregate having an average density of between 2400 and 3000 lbs./yard3; blowing air to create a pressurized air stream having an initial pressure of 18 psig and an initial volume of at least 1350 scfm; metering an amount of the aggregate from the container into the pressurized air stream; moving the amount of aggregate through a member at a flow rate of 30 yards3/hour so that the aggregate travels a distance of at least 80 feet; and manually moving the member to disperse the aggregate to the destination. 2. The method of claim 1, which includes the step of conveying the aggregate within the container to a position for metering the aggregate into the air stream. 3. The method of claim 1, which includes metering an amount of water into the air stream and guiding the air stream, aggregate and water to the destination. 4. The method of claim 1, wherein guiding the air stream includes passing the air stream through a hose. 5. The method of claim 1, wherein the air stream has an initial pressure of at least 20 psig and an initial flowrate of at least 2100 scfm. 6. The method of claim 1, which includes enabling an operator to remotely control the metering of the aggregate. 7. The method of claim 1, which includes adjusting a conveying device automatically if too much or not enough aggregate is being conveyed within the container to a device that meters the aggregate to the air stream. 8. The method of claim 1, wherein guiding the aggregate is performed for a purpose selected from the group consisting of: covering an area of land, filling a cavity in the ground and building a mound on the ground. 9. The method of claim 1, wherein the destination is selected from the group consisting of: an area around a tree or bush, a park, a playground, a schoolyard, a waterway, a roadway or driveway, a parking lot, a rooftop, around railroad tracks and any combination thereof. 10. The method of claim 1, wherein the aggregate includes at least one component selected from the group consisting of: sand, gravel, stone, crushed rock, rolled rock, porous rock, volcanic rock, different sized rock, differently colored rock, riprap rock and any combination thereof. 11. The method of claim 1, wherein the aggregate includes a rock having a maximum size of up to three inches. 12. A method for low pressure dispersing of dence material comprising the steps of: moving a container proximate to a destination, the container holding a bulk supply of a material having an average density of between 2400 and 3000 lbs./yard3; using a blower motor to create an air stream having an initial pressure of 18 psig at an initial volume of at least 1350 scfm; metering an amount of the material from the container into the air stream; maintaining the air stream so that the amount of material is blown a distance of at least 80 feet at a flowrate of at least 30 yards3/hour; and manually guiding the air stream so that the material is dispersed to the destination. 13. The method of claim 12, wherein the material is selected from the group consisting of: aggregate and slag. 14. The method of claim 12, which includes metering an amount of water into the air stream and guiding the air stream, material and water to the destination. 15. The method of claim 12, which includes injecting at least one additive into the air stream with the material. 16. The method of claim 12, wherein blowing the aggregate is performed for a purpose selected from the group consisting of: covering an area of land, filling a cavity in the ground and building a mound on the ground. 17. The method of claim 12, which includes moving the container by vehicle, railroad car or boat. 18. A method for low pressure dispersing of dense material comprising the steps of: moving a container proximate to a destination, the container holding a bulk supply of a material having an average density of between 2400 and 3000 lbs./yard3; blowing air to create an air stream having an initial pressure of 18 psig at an initial volume ofat least 1350 scfm; metering an amount of the material from the container into the air stream; maintaining the air stream so that the material is blown a distance of at least 80 feet at a flow rate of at least 30 yard3/hour; and manually guiding the air stream so that the material is dispersed to the destination. 19. The method of claim 18, wherein the material is selected from the group consisting of: aggregate and slag. 20. The method of claim 18, which includes metering an amount of water into the air stream and guiding the air stream, material and water to the destination. 21. The method of claim 18, which includes injecting at least one additive into the air stream and combining the material and additive. 22. The method of claim 18, wherein blowing the aggregate is performed for a purpose selected from the group consisting of: covering an area of land, filling a cavity in the ground and building a mound on the ground. 23. The method of claim 18, which includes moving the container by vehicle, railroad car or boat. 24. The method of claim 1, wherein the air stream has an initial pressure of at least 25 psig and an initial flowrate of at least 2300 scfm. 25. The method of claim 12, wherein the air stream has an initial pressure of at least 20 psig and an initial flowrate of at least 2100 scfm. 26. The method of claim 12, wherein the air stream has an initial pressure of at least 25 psig and an initial flowrate of at least 2300 scfm.
