Brief introduction:

4-7CBM concrete mixing drum adopt latest technology and auto-welding technology, the mixing blades adopt three-dimensional double helix mixing design to reduce remnant rate, also called concrete mixer drum.

Concrete mixing drum also called cement mixer drum, the benefits have
◆ Adopt auto-welding technology, all welding seams are checked by fault-indicator to make sure its welding quality.
◆ The blades are made by punching machine, ensure the dimension is exactly correct, the blades has unique wear; resisting protection structure, improving blade service life 80% High quality of hydraulic system
◆ Optimized design of concrete mixing tank, improve loading ability, reasonable mixing arms and holes distribution can ensure mixing on average without separation.
◆ Mixing blades adopt three-dimensional double helix mixing design, reducing remnant rate of 0.6%, better than international standard (international standard is 2%), ahead of industry standard (industry standard is 0.7%~1%)
◆ Large rounded spinning head of concrete mixing tank, flawlessly mixing and no residual concrete

As one of main parts of concrete mixing drum or drum for concrete mixers, the Hydraulic system adopt international top-brand, such as Germany, Italian, American brand with integral structure, excellent performance.
4-7CBM concrete mixing drum maybe used with concrete pump, the concrete pump hose adopt Germany EMB, and the hose adopt Italian MANULI. We can also produce the concrete mixing drum to enough customer’s requirements. We can also adopt Chinese famous brand hydraulic system and Accessories

4-7CBM concrete mixing drum cleaning is important, this can keep the engine operating smoothly for the next time. Regularly clean, we can reduce the concrete mixer drum maintenance.
