There are mainly three concrete mixer types: compulsory concrete mixer, rotary mixer and planetary mixer.
Compulsory concrete mixer
It includes double shaft mixer and single shaft mixer. The main models of the twin shaft concrete mixer: JS4000, JS3000, JS2000, JS1500, JS1000, JS750, JS500. The single shaft concrete mixer include the following models: JDC500 and JDC350.
The mixing drum of the compulsory concrete mixer is fixed and the material is mixed by the rotation of the blades on the rotating shaft in the drum. It has strong mixing performance and high mixing capacity. It is mainly used for the mixing of hard concrete and lightweight aggregate concrete.
The rotary mixer, also called concrete mixer drum can be divided into gear type and friction type according to their different transmission modes. Among them, gear type drum mixer includes JZC500, JZC350, JZC250,etc. The friction type rotary mixer is JZM750.
It is to 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 the mixture falls freely by its own weight. It can mix mix plastic and semi-plastic concrete.
The drum mixer has the advantages of reliable transmission, low noise, low energy consumption, compact structure, stable operation, easy operation, good mixing quality and high productivity.
The planetary mixer is also called counter-current concrete mixer, a special mixer equipment for high-grade concrete. It can well handle complex structural materials and complete high-quality mixing, realizing high-speed, high-quality, high-homogeneous stirring.
The counter-current mixer features low failure rate. Except for the replacement cost of wearing parts,, it does not have the common failure of other mixers, that is shat end leaking. Its vertical structure design completely avoids the occurrence of shaft end problems.
Among these three types of concrete mixers, rotary mixer is a relatively cheap concrete mixer, but its low efficiency and low mixing quality can’t meet the high requirements. The twin shaft mixer is the main concrete mixer which is widely used in various concrete batching plants.
