Some customers don’t know how to choose suitable concrete mixers, so, here Henan Daswell Machinery will introduce some chief factors in choosing concrete mixer.There are three factors: engineering quantity and duration Belt Type Portable Concrete Batch Plant, designed class of concrete, and composition characteristic and viscosity of concrete.Henan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China. We are dedicated to supplying our customers with best service and products, our major products include:small concrete batching plant,cement batching plant,Mobile concrete mixer,If you are interested in our products, please contact us freely: sales@daswell.com First, engineering quantity and duration: it is suitable to choose mid-and large-sized fixed concrete mixer if the concrete engineering quantity is large and the duration is a long term; it is suitable to choose small- and mid-sized mobile concrete mixer if the engineering quantity is small and the duration is short. Second, designed class of concrete: if the concrete is plastic or semi-plastic concrete batching plant manufacturers, you’d better choose self-falling concrete mixer; if the concrete is high intensity, hard or lightweight concrete, you’d better choose forced concrete mixer. Third, composition characteristic and viscosity of concrete: if the concrete’s viscosity is low but the aggregate is big, you should use self-falling concrete mixer concrete mixer pump, whose capacity is larger; if the viscosity is high and the aggregate is big, you should use self-falling concrete mixer, whose rotating speed is fast; if the viscosity is high but the aggregate is small, you’d better choose forced concrete mixer or the small capacity wimble concrete mixer, who discharges when rotating reversely.
