Twin Shaft Concrete Mixer

JS II concrete mixer
,Twin shaft Concrete Mixer is the second generation of the compulsory horizontal type concrete mixer. It is excellent in energy efficiency and time saving. The technology of separating the shaft bearings from the shaft sealing makes the sealing is easily accessible for maintenance. We offer wear-resistant materials from the shell to liners improving the life of the products dramatically. The mixer (JS II) employs advanced technology in driving introduced from Italy. Moreover, except for hydraulic control system for discharge electrically or manually, it adds pneumatic device. The machine is a classic twin shaft concrete mixer meeting the requirements of medium to high concrete output. Thanks to its design, JS II concrete mixer is extremely reliable and reflects the state of the art. What`s more, it is high quality with competitive price.

Different sizes and versions

Twin shaft concrete mixer is mainly composed of main case, spiral shaft assembly, driving unit, tubing, detent plate cover, cover chain and other components. Specific structural properties of horizontal type concrete mixer are as followings:

The case of twin shaft concrete mixer is mainly made of plates and profile steel. The case is welded in concrete mixer factory and is   assembled with other parts of JS II concrete mixer. The case is the brace of twin shaft concrete mixer. The case is tightly sealed, so there is no fly ash and leakage phenomenon.

The spiral shaft assembly is the main component of twin shaft concrete mixer. The spiral shaft assembly is mainly composed of left and right rotation screw shafts, bearing seat, bearing holder, bearing cover, gear, sprocket wheel, oil cup, blades and other components and parts.

Left and right rotation screw shafts has high manufacturing accuracy, good processing property. There are strict coordinating requirements for left and right rotation screw shafts with bearing seat, bearing holder and bearing cover. Gear and sprocket wheel all have protective cover to protect them and they can be safely and effectively operated. Oil cup is pressure injection oil cup, so it is convenient and effective to add lubricating oil. The blades are made of wear-resistant materials.The blade structure is reasonably and simply designed. So it is easy to replace blades after wearing. At the same time, the blades have long service life.

Tubing mainly consists of connecting pipe, joints and nozzle.

Detent plate cover is mainly composed of left detent plate cover, middle cover, right detent plate cover, opercle and maintenance opercle.
