The purpose is to mechanically mix cement concrete. According to the operation mode, there are two types of cyclic operation and continuous operation.
The three processes of feeding, stirring and discharging of the cycle operation are carried out according to a certain time interval, that is to say, according to the parts mixing system. The quality of mixing is good because the materials made by mixing are weighed accurately. At present, most of these operations are used.
The three processes of continuous operation are carried out continuously in a longer barrel. Although its productivity is higher than that of cycle operation, the mixing quality is poor due to the mixing ratio of each material and the difficulty of mixing time. Less currently used.
