A rotary concrete mixing drum () for a vehicle () having a drivetrain () for rotating the drum () includes a wall () having an opening () and a hatch cover assembly () removably closing the opening. The hatch assembly () may include a hatch cover () coupled to a panel () by bolts ().

Mixing drum hatch

A rotary concrete mixing drum () includes an interior surface () at least partially provided by a polymer () impregnated with a slip agent.

Mixing drum

A concrete mixing drum includes a wall having a first section () and a second section (). The first section () extends in a spiral along an axial centerline () of the drum. The second section () extends in a spiral along the axial centerline () of the drum adjacent to the first section ().

A concrete mixing drum includes a wall having at least one projection () integrally formed as part of a unitary body with the wall. The at least one projection extends from the inner surface of the wall and includes a tapered base region proximate the inner surface of the wall.

Mixing drum blade

A concrete batch plant is disclosed including a frame and a transit mixer drum having an open end and a closed end. The drum is configured to be utilized both with the concrete batch plant and on a transit mixer truck. The drum may be pivotally coupled to the frame of the concrete batch plant for movement between a first position in which the open end is positioned to receive cement from a cement supply and to receive aggregate from an aggregate supply and a second position in which the open end is positioned to discharge the mixed cement and aggregate. Further, the drum may be a polymeric drum including an interior surface formed by a plurality of complementary molded helical polymeric sections joined along a helical seam.

Concrete batch plant with polymeric mixer drum

A heavy duty rotary concrete mixing drum () for coupling to a vehicle () having a powered drivetrain () for rotating the drum comprises a wall and at least one projection (). The wall () includes an inner surface () defining a volume and an outer surface (). The at least one projection is coupled to the wall and extends from the inner surface of the wall. The projection includes a body and a support member () disposed within the body.

Mixing drum blade support

A method of manufacture of a vehicle mounted rotary concrete mixing drum of the type having an opening at one end for receiving and/or discharge of concrete therefrom and at the other end, means for engaging a drive assembly so as to rotate the drum for mixing or discharging concrete. The drum is manufactured from at least one mold using at least one plastics material and further includes integrally attached vanes which outstand from the internal surface of the drum forming an archimedian spiral disposed such that when the drum is rotated in a first direction the concrete contents are mixed and when the drum is rotated in a second direction the contents are discharged from the drum; wherein, the method comprises the steps of;

Vehicle mounted concrete mixing drum and method of manufacture thereof

A method for making a concrete mixing drum includes forming a first layer of at least one polymeric material having a surface providing at least a portion of a barrel wall of the drum and a spiral mixing blade projecting from the wall on an inner surface of the drum and forming a second layer on the formed first layer.

Concrete mixing drum manufacturing method

A heavy duty rotary concrete mixing drum capable of attachment to a vehicle. The drum comprises a first end which engages a vehicle powered drive assembly which rotates the drum for mixing of said concrete and a second end from which mixed concrete is discharged. The drum is manufactured from at least one layer of plastics material; wherein the drum includes a wall having integral internal formations which promote mixing and discharge of said concrete and an inner surface which promotes mixing of the concrete.
