Mixing of concrete in batch mixers is done by pouring raw materials with a certain ratio into the mixer chamber and rotating the chamber at a constant speed. Upon completion of mixing, the mortar will be discharged and the mixing process will be repeated for the next batches. This process continues until the required volume of concrete is reached. The types of batch mixer according to the rotation axis are:

"Drum Mixer" or barrel mixer: horizontal or inclined axis
"Pan Mixer" or pot mixer: axis Vertical

What is a drum mixer and what are its types?Drum mixer is one of the most widely used types of batch mixers, whose chamber is similar to a barrel and whose axis is horizontal or It is steep. Drum mixers are divided into tilting, non-tilting and reverse types:

"Tilting Drum Mixer": concrete discharge in these mixers by rotating its housing It takes place downwards. The tilting drum mixer can be set at different angles. Non-Tilting Drum Mixer: The housing of this mixer is always horizontal and its direction can be changed. does not. The act of unloading concrete The drum mixer without inclination is made by an inclined shot. "Reverse Drum Mixer": This type of mixer is similar to the drum mixer without inclination with two openings on each side. is itself with the difference that one of these openings is used for the entry of raw materials and the other opening is used for the exit of concrete. The rotation of the chamber during the entry of raw materials is in a certain direction. The direction of rotation is reversed when the concrete comes out. The existence of two series of blades (mixing and draining) enables this function.
