The concrete mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixtures. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. According to the nature of work, it is divided into batch type (batch type) and continuous type; according to the principle of mixing, it is divided into self-falling type and forced type; according to the installation method, it is divided into fixed type and mobile type; according to the discharging method, it is divided into tilting type and non-tilting type; According to the structure of the mixing drum, it is divided into pear type, drum type, double cone, disc vertical shaft type and circular groove horizontal shaft type.
