(1) Structure of concrete mixer
Concrete mixer is a machine that mixes cement, aggregate and water to make concrete mixture. It is mainly composed of mixing drum, feeding and discharging mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. At present, the concrete mixer is widely used in industrial and civil engineering, in the mixing plant equipment, the concrete mixer plays an irreplaceable role.
(2) Different classification of concrete mixer
·According to the operation mode: cycle operation concrete mixer, continuous operation concrete mixer
The three processes of mixing, feeding, mixing and discharging are carried out periodically according to a certain time interval, i.e. mixing by parts. All kinds of materials are accurately weighed, so the mixing quality is good. At present, this type of operation is mostly used.
Continuous operation the above three processes are carried out continuously in a long cylinder, and the mixing ratio and mixing time of each material are difficult to control, so the mixing quality is poor. At present, it is less used.
·According to mixing methods: self falling concrete mixer, forced concrete mixer
JZC500), JZC350 and JZC250 are popular models of self falling mixers in Pengfei Construction Machinery Co., Ltd.: (self falling mixers put the mixture in a rotating mixing drum. With the rotation of the mixing drum, the blades in the drum lift the mixture to a certain height, and then scatter it freely by self weight. Repeat until well mixed. It is often used to mix plastic and semi-plastic concrete.
Forced mixer jdc500, jdc350, JS4000, JS3000, JS2000, JS1500, JS1000, js750, JS500 Pengfei hot-selling forced mixer models are: (single horizontal shaft forced type and double horizontal shaft forced type, the mixing drum does not move when it works, but forced mixing by blades on the rotating shaft in the drum. This kind of mixer has good mixing quality, high production efficiency, high power consumption and fast blade wear. It is generally suitable for mixing dry and hard concrete.)
·According to the device mode: fixed mixer. Mobile mixer
