TWIN SHAFT MIXERS ARE KNOWN TWIN SHAFT MIXERS ARE KNOWN FOR THIER HIGH INTENSITY MIXING IN FOR THIER HIGH INTENSITY MIXING IN SHORT PERIOD OF TIME.SHORT PERIOD OF TIME.

THESE MIXERS ARE TYPICALLY USED THESE MIXERS ARE TYPICALLY USED FOR HIGH STRENGTH CONCRETE IN FOR HIGH STRENGTH CONCRETE IN BATCHES OF 2.6 – 7.8 CUBIC YARDS.BATCHES OF 2.6 – 7.8 CUBIC YARDS.

VERTICAL AXIS MIXERVERTICAL AXIS MIXER

VERTICAL AXIS MIXERVERTICAL AXIS MIXER

VERTICAL AXIS MIXERS ARE MOST VERTICAL AXIS MIXERS ARE MOST COMMONLY USED FOR THE COMMONLY USED FOR THE PRODUCTION OF COLOURED PRODUCTION OF COLOURED CONCRETE AND SMALLER BATCHES CONCRETE AND SMALLER BATCHES OF O.98 – 3.9 CUBIC YARDSOF O.98 – 3.9 CUBIC YARDS

DRUM MIXERDRUM MIXER


DRUM MIERS ARE USED WHERE LARGE DRUM MIERS ARE USED WHERE LARGE VOLUME OF CONCRETE IS BEING VOLUME OF CONCRETE IS BEING PRODUCED.PRODUCED.THE BATCHE SIZE IS RANGING FROM 3.9 – THE BATCHE SIZE IS RANGING FROM 3.9 – 12 CUBIC YARDS.12 CUBIC YARDS.THIS TYPE OF MIXERS DOMINATE THE THIS TYPE OF MIXERS DOMINATE THE READY MIXED MARKET AS IT IS KNOWN TO READY MIXED MARKET AS IT IS KNOWN TO BE CAPABLE OF HIGH PRODUCTION SPEED, BE CAPABLE OF HIGH PRODUCTION SPEED, IDEAL FOR SLUMP CONCRETE AND WHERE IDEAL FOR SLUMP CONCRETE AND WHERE OVERALL COST OF PRODUCTION IS OVERALL COST OF PRODUCTION IS IMPORTANT.IMPORTANT.


DRUM MIXERS ARE KNOWN TO HAVE DRUM MIXERS ARE KNOWN TO HAVE THE LOWEST MAINTANCE AND THE LOWEST MAINTANCE AND OPERATING COST.ALL THE THREE OPERATING COST.ALL THE THREE TYPES OF MIXERS ARE USED TO TYPES OF MIXERS ARE USED TO VARYING DEGREE IN ALL PARTS OF VARYING DEGREE IN ALL PARTS OF THE WORLD.THE WORLD.

TYPES OF DRUM MIXERTYPES OF DRUM MIXER

DRUM MIXERS ARE BROADLY DRUM MIXERS ARE BROADLY CLASSIFIED INTO TWO MAIN CLASSIFIED INTO TWO MAIN CATAGORIES:-CATAGORIES:-

(1) TILTING DRUM MIXER(1) TILTING DRUM MIXER

(2) NON-TILTING DRUM MIXER(2) NON-TILTING DRUM MIXER

THESE TYPES OF MIXERS ARE THESE TYPES OF MIXERS ARE GENERALLY USED FOR MINI GENERALLY USED FOR MINI PROJECTS.PROJECTS.

THEY HAVE A LEVER OR HANDLE THEY HAVE A LEVER OR HANDLE WITH THE HELP OF WHICH THE WITH THE HELP OF WHICH THE FRESHLY MIXED CONCRETE IS FRESHLY MIXED CONCRETE IS DISCHARGED OR TIPPED INTO A DISCHARGED OR TIPPED INTO A WHEELBARROWWHEELBARROW

IN THIS TYPE OF DRUM MIXERS THE IN THIS TYPE OF DRUM MIXERS THE BLADES INSIDE THE DRUM ARE BLADES INSIDE THE DRUM ARE DESIGNED SO THAT ON REVERSING DESIGNED SO THAT ON REVERSING THE ROTATION THE CONCRETE IS THE ROTATION THE CONCRETE IS DISCHARGED FROM THE DRUM.DISCHARGED FROM THE DRUM.

HENCE THEY ARE ALSO KNOWN AS HENCE THEY ARE ALSO KNOWN AS REVERSING DRUM MIXERS.REVERSING DRUM MIXERS.

TYPES OF DRUM MIXERTYPES OF DRUM MIXER

DOUBLE DRUM AND TRIPLE DRUM DOUBLE DRUM AND TRIPLE DRUM MIXERS ARE ALSO USEDMIXERS ARE ALSO USED

THEY REDUCE THE LABOUR COST THEY REDUCE THE LABOUR COST WHERE AS THE PRODUCTIVITY IS WHERE AS THE PRODUCTIVITY IS NOT AFFECTED.NOT AFFECTED.

IT IS ALSO KNOWN AS IN-TRANSIT IT IS ALSO KNOWN AS IN-TRANSIT MIXERMIXER

THEY ARE MADE TO TRANSPORT AND THEY ARE MADE TO TRANSPORT AND MIX CONCRETE UP TO THE MIX CONCRETE UP TO THE CONSTRUCTION SITECONSTRUCTION SITE

THEY CAN BE CHARGED WITH DRY THEY CAN BE CHARGED WITH DRY MATERIALS AND WATER, WITH MIXING MATERIALS AND WATER, WITH MIXING OCCURING DURING TRANSPORTOCCURING DURING TRANSPORT


WITH THIS PROCESS , THE WITH THIS PROCESS , THE MATERIALS HAS ALREADY BEEN MATERIALS HAS ALREADY BEEN MIXING.MIXING.

IT MAINTAIN THE MATERIAL’S LIQUID IT MAINTAIN THE MATERIAL’S LIQUID STATE THROUGH TURNING OF THE STATE THROUGH TURNING OF THE DRUM UNTIL DELIVERYDRUM UNTIL DELIVERY


THE INTERIOR OF THE DRUM IS THE INTERIOR OF THE DRUM IS FITTED WITH A SPIRAL BLADE.FITTED WITH A SPIRAL BLADE.

IN ONE ROTATIONAL DIRECTION THE IN ONE ROTATIONAL DIRECTION THE CONCRETE IS PUSHED INTO THE CONCRETE IS PUSHED INTO THE DRUMDRUM

THIS IS KNOWN AS CHARGING THE THIS IS KNOWN AS CHARGING THE MIXERMIXER


WHEN THE DRUM REVERSE ITS WHEN THE DRUM REVERSE ITS ROTATIONAL DIRECTION THE SREW ROTATIONAL DIRECTION THE SREW TYPE ARRENGEMENT OF THE BLADE TYPE ARRENGEMENT OF THE BLADE FORCES THE CONCRETE OUT OF THE FORCES THE CONCRETE OUT OF THE DRUMDRUM

WORKING OF MIXERWORKING OF MIXER

THE REVOLVING DRUM IS USED TO THE REVOLVING DRUM IS USED TO MIX ALL THE COMPONENTS OF MIX ALL THE COMPONENTS OF CONCRETE CONCRETE THE DRUM IS ATTACHED WITH THE DRUM IS ATTACHED WITH USUALLY TWO ROLLARS WHICH ARE USUALLY TWO ROLLARS WHICH ARE OPERATED BY A MOTOROPERATED BY A MOTORWATER, CEMENT AND AGGREGATES WATER, CEMENT AND AGGREGATES ARE PUT INSIDE THE REVOLVING ARE PUT INSIDE THE REVOLVING DRUM IN A DESIRED PROPORTIONDRUM IN A DESIRED PROPORTION


FOR EXAMPLE IF YOU WANT HIGH FOR EXAMPLE IF YOU WANT HIGH STRENGTH CONCRETE, THEN USE STRENGTH CONCRETE, THEN USE 1:2:4 RATIO OF CEMENT, SAND AND 1:2:4 RATIO OF CEMENT, SAND AND GRAVAL RESPECTIVELLYGRAVAL RESPECTIVELLY

WATER IS THEN ADDED ACCORDING WATER IS THEN ADDED ACCORDING TO THE CEMENT AMOUNT, TO CARRY TO THE CEMENT AMOUNT, TO CARRY OUT THE HYDRATION PROCESS OF OUT THE HYDRATION PROCESS OF CEMENTCEMENT


THE WATER/CEMENT RATIO IS THE WATER/CEMENT RATIO IS GENERALLY 0.5 BUT CAN BE GENERALLY 0.5 BUT CAN BE REDUCED TO 0.25REDUCED TO 0.25

WHEN THE DRUM ROTATES IT MIX ALL WHEN THE DRUM ROTATES IT MIX ALL THE COMPONENTS HOMOGENOUSLYTHE COMPONENTS HOMOGENOUSLY

THE ROTATION SPEED IS GENERALLY THE ROTATION SPEED IS GENERALLY 20-36 ROUNDS PER MINUTE20-36 ROUNDS PER MINUTE


AFTER 1 OR 2 MINUTES THE AFTER 1 OR 2 MINUTES THE CONCRETE IS DISCHARGED INTO A CONCRETE IS DISCHARGED INTO A CHUTECHUTE

A CHUTE IS A CONTAINER THAT GUID A CHUTE IS A CONTAINER THAT GUID THE CONCRETE TO A WHEELBARROWTHE CONCRETE TO A WHEELBARROW


AFTER THIS PROCESS THE DRUM IS AFTER THIS PROCESS THE DRUM IS THEN WASHED WELL SO THAT THE THEN WASHED WELL SO THAT THE CEMENT MAY NOT STICK TO ITCEMENT MAY NOT STICK TO IT
