A clear water control device of a high energy mixer, and a high energy mixer. The clear water control device comprises a mounting base (1), a straight line actuator (3), a hinge shaft (4), a rocker arm (8), a lead screw (5), a threaded shaft (6) and a valve rod (9). The mounting base (1) is hinge-connected with a fixing seat (12) of the straight line actuator (3). The hinge shaft (4) is inserted in a middle shaft hole of the mounting base (1). One end of the lead screw (5) is fixed on the hinge shaft (4). The threaded shaft (6) sleeves the middle part of the lead screw (5). The threaded shaft (6) is inserted in a middle hole of the rocker arm (8). The upper end of the rocker arm (8) is hinge-connected with the valve rod (9). The lower end of the rocker arm (8) is hinge-connected with a push rod (11) of the straight line actuator (3). A through hole is arranged at the junction of the threaded shaft (6) and the lead screw (5). A pin (10) is arranged in the through hole. The automatic precision control of the amount of feed of the valve rod (9) is achieved, so that the slurry mixing effect of the high energy mixer is better than that in the prior art.

A system for calculating and reporting slump in a delivery vehicle having a mixing drum 14 and hydraulic drive 16 for rotating the mixing drum, including a rotational sensor 20 configured to sense a rotational speed of the mixing drum, a hydraulic sensor 22 coupled to the hydraulic drive and configured to sense a hydraulic pressure required to turn the mixing drum, and a communications port 26 configured to communicate a slump calculation to a status system 28 commonly used in the concrete industry, wherein the sensing of the rotational speed of the mixing drum is used to qualify a calculation of current slump based on the hydraulic pressure required to turn the mixing drum.

A concrete mixer truck includes: a driving device that drives a mixer drum to rotate; a pressure sensor that detects a pressure of the working fluid in the driving device; a material introduction determination unit that determines whether or not a material for generating the mixed concrete has been introduced into the mixer drum; a pressure determination unit that determines whether or not the pressure of the working fluid detected by the pressure sensor has fallen to a set pressure set in advance in accordance with a carrying amount and a fluidity of the mixed concrete after the introduction of the materials for the mixed concrete into the mixer drum; and a notification device that notifies an operator that the pressure of the working fluid in the driving device has fallen to the set pressure on the basis of the determination made by the pressure determination unit.

A process and equipment for producing multi-color concrete products, including architectural concrete blocks, concrete bricks, modular concrete products that are suitable for use in landscaping applications, such as retaining wall blocks, concrete pavers, and concrete slabs. The invention includes a spray mechanism that sprays liquid pigment onto concrete discharged from a hopper. The concrete then proceeds to a blending mechanism which blends the pigment into the concrete to produce a multi-color concrete blend. The concrete blend is then used to produce multi-colored concrete products.

A concrete batch mixing system and method are disclosed that enable the batch master to measure and control both the water and cementitious ingredient feeds in relation to each other so as to be able to blend the two ingredients in a known, selected, adjustable and repeatable manner, and to agglomerate these ingredients in a counter-rotating twin screw mixing apparatus for use in the preparation of batches of mixed concrete in a concrete batching process.

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).
