Mixer – a semi-automatic device for the preparation of construction build-mix concrete and mortar by mixing its components. Typically, they use a drum motor for mortar.

cement mixers can be divided into two types: the first type of device is the gravitational stirring blade features of which are set in the drum. The blades are mounted so that the result is a homogeneous composition quality due to the repeated rise and fall of the mixture. The second type relates to forced stirring mixers, which are cyclic movement with a fixed capacity.
