, using the whole body structure, cast steel mixing arm, seat and square tubular agitator shaft bolt adjacent mixing arm angle 90°, large-size European stirred tank mixing blade structure, aggregate size of concrete slump and the adaptation range. BONA produces JS series twin-shaft concrete mixer from the tank, mixing shaft assembly, shaft seal and bearing device, drive, discharge gate devices and cover other components. Using two sets of parallel synchronous drive apparatus drive, there are parallel shaft gear reducers and right angle shaft drive two types, the mixer's work run more reliable, more convenient maintenance and overhaul, life has improved significantly.
BONA while using a number of proprietary and patented technologies, such as the stirring shaft eccentric technology of , diamond liner, eccentric discharge gate technology, unique sealing structure consisting of five shaft seals, shaft bearing and shaft seal separation of the structure and so on.
