Mobile mixing devices, systems and related methods

A multiple purpose mobile mixing system comprising:

• a multiple purpose mobile mixing device comprising:
• a frame;
• a mixing drum securable to the frame, the mixing drum comprising a body that forms an internal cavity and having an open end and a closed end, the mixing drum comprising a mouth at the open end of the body that provides access to the internal cavity of the mixing drum;
• a heater support arm comprising electric and hydraulic lines and a heater secured to an end of the heater support arm that is distal from the mixing drum, the heater support arm being movable between a stow-away position such that the heater support arm is off to a side of the mixing drum and a heating position with the heater facing into the mouth of the mixing drum with the heater support arm comprising quick disconnect pins;
• quick connect for the hydraulic and electric lines for connection and disconnection of the hydraulic and electrical lines associated with the heater support arm, the quick disconnect pins and the quick connects for the hydraulic and electric lines making heater support arm easily removable and reattachable;
• and
• a mixing drum drive engageable with the mixing drum to rotate the mixing drum;
• and
• the mixing drum usable to process either flowable fill or cement in the internal cavity of mixing drum when the heater support arm is in the stow-away position and usable to process asphalt when in the heater support arm is in the heating position with the heater facing into the mouth of the mixing drum;
• and
• at least one of the following:
• a conveyor transportable with the multiple purpose mixing device, the conveyor positionable to carry material from a staging location to the mouth of the mixing drum upon arriving at a desired jobsite;
• or
• a loading bin transportable with the multiple purpose mixing device, the loading bin configured to receive material to be loaded into the mouth of the mixing drum of the multiple purpose mixing device.
