A portable mixing apparatus for mixing components is disclosed. The apparatus comprises a container for receiving components to be mixed, a frame for supporting the container in a first orientation for mixing components and a driving assembly couplable with the container for rotating the container. The frame comprises: a first handle for gripping with a first hand of a user, the first handle being disposed above a centre of mass of the portable mixing apparatus, when orientated in the first orientation, the first handle extending forwardly of the apparatus over the container; a second handle for gripping with a second hand of the user while the first hand grips the first handle, the second handle being disposed below the centre of mass of the portable mixing apparatus when orientated in the first orientation, the first and second handle being arranged to enable the user to carry the mixing apparatus and re-orientate the apparatus between the first orientation and a second orientation for emptying the components from the container.

A mixing drum includes a body defining a head aperture and a discharge aperture opposite the head aperture, a head coupled to the body and extending across the head aperture, and a mixing element positioned within the volume and coupled to the body. The head and the body define a volume. The body is formed from at least a first section and a second section. The first section overlaps the second section.

Mobile mixing devices, mobile mixing systems, and related methods are provided. A mobile mixing device can include a frame and a mixing drum securable to the frame. The mixing drum can include a body that forms an internal cavity and can have a forward end and a bottom end. The mixing drum can also include a mouth at the forward end of the body that provides access to the internal cavity of the mixing drum. The mobile mixing device can include a heater support arm having a heater secured to an end of the heater support arm that is distal from the mixing drum. The mixing drum can be used to process cement material when the heater support arm is in a stow-away position or used to process asphalt when the heater support arm is in a heating position with the heater facing into the mouth of the mixing drum after loading of the asphalt.

A mixing drum includes a body defining a head aperture and a discharge aperture opposite the head aperture, a head coupled to the body and extending across the head aperture, a bearing member coupled to the body and defining a bearing surface surrounding the body, and a mixing element positioned within the volume and coupled to the body. The head and the body define a volume configured to contain a fluid mixture. The mixing element is configured to drive the fluid mixture toward the head when the drum is rotated in a first direction. The mixing element is configured to drive the fluid mixture towards the discharge aperture when the mixing drum is rotated in a second direction opposite the first direction. The head is made from a first material, and the body is made from a second material having a lesser density than the first material.

A concrete mixer vehicle comprises a chassis, an engine, a cab, a drum assembly, a front roller pedestal, a transmission mounting bracket assembly, and a rear pedestal. The chassis has a frame. The drum assembly includes a mixing drum, a drum driver, and a hopper assembly. The front roller pedestal is configured to support a front end of the mixing drum. The front roller pedestal includes a support member configured to provide support to the front roller pedestal in a longitudinal direction with respect to a longitudinal axis of the frame. The rear pedestal is configured to support a rear end of the mixing drum. The rear pedestal includes a first bar-pin member and a second bar-pin member configured to couple the rear pedestal in a first installation position or a second installation position based on a length of the mixing drum.

Mobile mixing devices, mobile mixing systems, and related methods are provided. A mobile mixing device can include a frame and a mixing drum securable to the frame. The mixing drum can include a body that forms an internal cavity and can have a forward end and a bottom end. The mixing drum can also include a mouth at the forward end of the body that provides access to the internal cavity of the mixing drum. The mobile mixing device can include a heater support arm having a heater secured to an end of the heater support arm that is distal from the mixing drum. The mixing drum can be used to process cement material when the heater support arm is in a stow-away position or asphalt when the heater support arm is in a heating position with the heater facing into the mouth of the mixing drum.

Apparatuses and methods based thereon are provided for mixing utilizing mixer inserts. A mixer insert may be adapted to enclose a space in a container, with the mixer insert having one or more securing components for securing the mixer insert to the container, and one or more mixing components, adapted to fit within the enclosed space when the mixer insert is secured to the container, with the one or more mixing components being configured to mix material placed within the enclosed space when the container is subject to a rotational force or movement. The mixer insert may have a closing section that has a shape matching an opening of the container, with the mixer insert being configured such that the closing section engages the opening of the container. At least one of the mixing components may be a blade, which may be twisted along the length of the blade.

The present disclosure provides for a reversible and adjustable stopper assembly comprised of an upper frame, L-bracket, connector portion and stopping member. The stopper can be configured to be secured to at least two main types of press brakes. The stopping portion of the stopper is also reversible, allowing for less sheet metal to be inserted into the press brake, if desired. The stopper assembly can be slid in a horizontal manner, relative to the press brake to preserve the measurement of the sheet metal from one end of the press brake to the other.

The invention provides compositions and methods directed to carbonation of a cement mix during mixing. The carbonation may be in a stationary mixer or a transportable mixer, such as a drum of a ready-mix truck.

Apparatuses and methods based thereon are provided for mixing utilizing mixer inserts. A mixer insert may comprise an enclosing component adapted for application to an opening in a container to which the mixer insert is applied, to enclose a space in the container. The mixer insert may further comprise one or more mixing components, adapted to fit within the enclosed space when the enclosing component is applied to the opening in the container, with the one or more mixing components being configured to mix material placed within the enclosed space when the combination of the container and the mixer insert is subject to particular force or movement.
