At present, the common used concrete mixers have the discharging volume of 100L, 150L, 250L, 350L, 400L, 500L, 750L, 1000L, 1500L, 2000L, 3000L, 4000L. Discharging volume is the specification of concrete mixers , it on behalf of the total capacity of all the mixed material. According to the capacity, the concrete mixers can be divided into small size concrete mixer, middle size concrete mixer and large size concrete mixer. Different capacity concrete mixer is suitable for different project site, we can choose the type in accordance with the construction demand. Small concrete mixer refers to the discharging volume under 400L, at present, there are 100L, 250L, 350L 375L and so on, usually , the small size concrete mixers are JZC series, for example, we Haomei Machinery supply JZC350 which has wheels, it’s mixing capacity is 0.35m3. The middle size concrete mixer represent the working capacity between 400-1000L, the common models are 400L, 500L, 8000L and so on. We supply JZC500, JS7...
