Features: 1. JZCseries of concret mixer are a kind of gravity stabilized two-cone reverse tilting concrete mixer,the Mixing roller is driven by gear wheels,when it does positive rotation， the machine is stirring，or it will discharging,this mixer can stir plastic concrete and semirigid /hard concrete. It applies for construction site ,road,bridge projects and all kinds of concrete componet factory. 2 The JZCseries of mixers are designed and manufactured according to Concrete Mixer Tchnological Conditions GB/T9142-2000 ,it is an advanced machine which has resonable structure,high productivity,good mixing quality,graceful outline and convenient relocation,etc. 3.The series of mixers include five main moldes : JZC250、300、350、500 and 750, but JZC750 is fixed molde,which besides used as a single machine, it can form a simple mixing plant when it is connected with batching machine.The rest molde is moveable.
