HZS 25 concrete plant is a small concrete batch plant. It is applicable for making dry concrete, plastic concrete and fluid concrete, of which capacity is 25 m3. Therefore, it is an ideal choice for small-scale construction projects, precast yard and commercial concrete companies. There are large models of stationary concrete batching plant. FEATURES OF HZS25 STATIONARY MIXING PLANT International popular modular structure. Twin shaft compulsory concrete mixer brings even mixing effect. Main electrical components from Germany SIEMENS. Shaft-end sealing technology ensures no leakage. Wear-resisting steel lining board.
1. Machines replace manual pouring, increasing the speed by tens of times; 2. Continuous pouring ensures the quality of the project; 3. Save labor costs; 4. High buildings, basements, and places where ordinary equipment is difficult to construct can all be constructed, greatly reducing the difficulty of construction. 5. There are electric and diesel versions of concrete pumps, which do not rely much on power and are more flexible in construction.
Brand new concrete pump, model HBT40.13.60RS, HBT60.13.90S, HBT80.16,174RS, HBT100.21.195RS. for more
