Embodiments of the invention generally relate to apparatus and methods to control the addition of moisture to materials for the production of concrete.
摘要:
A cement mixing method and apparatus for mixing cement used in cementing oil wells casing and the mixer used in that method. The mixer employs a straight bulk cement inlet, five annular recirculation jets and five annular water jet orifices located downstream of the recirculation jets so that all of the jets discharge at an angle towards the mixing chamber and the discharge from the water jet orifices intersects with the flow from the recirculation jets. This five jet, intersecting flow design allows for more thorough wetting of the cement powder with a smaller, lighter, less expensive and more durable mixer that is less inclined to foul and easier to clean.

A present invention provides for a system (100) for injecting cooling fluid into a concrete mixing container (502), the system (100) comprising a support structure (116) having a leg assembly with two or more supporting legs (201) and a cross member beam (200) supported between said two or more legs (201), the two or more legs (201) and the cross member beam (200) being positioned with respect to one another in such a manner as to define a passageway (210) of sufficient height (H) and width (W) between the two or more legs (201) and beneath the cross member beam (200) to allow passage of a concrete mixer truck (504) through the passageway (210) and a lance device (190) positioned on the cross member beam (200) of the support structure (116), the lance device (190) comprising an articulated arm that includes a rigid lance (102) which allows for the flow of a cooling fluid there through; and a means for acting on the articulated arm to cause pivotal movement of the articulated arm in a non-linear motion thereby controlling the angle of the rigid lance (102) while at the same time controlling the insertion and retraction movement of the rigid lance (102) into the concrete mixing container (502) for fluid injection of the cooling fluid into the concrete mixing container (502). The present invention further comprises a process for injecting cooling fluid into a concrete mixing container (502).

The mixer employs a straight bulk cement inlet, five annular recirculation jet and five annular water jet orifices located downstream of the recirculation jets so that all of the jets discharge at an angle towards the mixing chamber. The five annular recirculation jets are located in alternating longitudinal alignment within the mixing chamber relative to the five annular water jets. This five jet, intersecting flow design allows for more thorough wetting of the cement powder with a smaller, lighter, less expensive and more durable mixer that is less inclined to foul and easier to clean.
摘要:
A concrete mixer having a drum, which contains mixing elements, and at least one vibrator for imparting vibrational energy to the material which is to be mixed. The vibrator is drivable by means of the water used to make up the concrete. The water may be discharged in a pulsating manner from a vibrating body which is caused to vibrate by this pulsation, or it may rotatably drive an eccentric mass in the vibrating body.

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.
