SICOMA Double Shaft Concrete Mixers

SICOMA double shaft mixers, based on classic European mixing technology, have undergone multiple generations of structural optimization and domestic process improvements, forming a complete product series from MAO1000 to MAO4000. They are the core standard main unit for stationary commercial concrete plants and mobile engineering mixing plants worldwide, widely adaptable to the mixing and production of various building materials such as ordinary commercial concrete, high-strength special concrete, and permeable mortar, holding a stable market share in the mid-to-high-end mixing equipment market.

SICOMA main production models of twin-shaft forced mixers include five types: MAO1000, MAO1500, MAO2000, MAO3000, and MAO4000. The effective discharge volumes per batch are 0.5m³, 0.75m³, 1.0m³, 2.0m³, and 3.0m³, respectively. Power configurations increase with specifications: MAO1000 is equipped with dual 18.5kW motors, MAO1500 with dual 22kW motors, MAO2000 with dual 30kW motors, MAO3000 with dual 37kW motors, and MAO4000 with dual 45kW motors, fully covering the needs of small prefabrication plants, mobile engineering mixing plants, and large and medium-sized environmentally friendly commercial concrete mixing plants.

The SICOMA double shaft mixer features a box-type integral cast-welded body, with the housing undergoing stress-relief annealing to prevent deformation during long-term heavy-load operation. Internally, it features a symmetrical, counter-rotating dual-spindle layout. The spindles are made of tempered and forged alloy steel, and the split-type plug-in agitator arm design facilitates easy replacement of easily worn parts. Core wear components are uniformly made of Ni-Hard high-hardness wear-resistant cast iron. The arrangement of the liners and agitator blades has been calculated using fluid simulation, ensuring uniform material collision and friction stress, significantly delaying component wear. The most critical shaft end area employs a multi-layer composite sealing structure, integrating a floating oil seal, wear-resistant bushing, and automatic grease injection circuit, fundamentally preventing slurry from seeping into the bearing cavity and solving the common industry problem of spindle slurry leakage.

The power transmission system uses an original imported planetary gear reducer. The motor and reducer are coaxially directly connected, eliminating the redundant intermediate coupling structure. Power transmission loss is controlled to within 5%, resulting in lower energy consumption compared to belt-driven models. The entire series of SICOMA mixers offers a single-batch effective discharge volume ranging from 1m³ to 4m³, with a standard mixing cycle time of 65-90 seconds. The three-dimensional convection mixing mode ensures uniform blending of aggregates, powders, and admixtures, producing high-strength concrete that meets the C80 standard, satisfying the high-specification material requirements for bridge and nuclear power plant precast components. Optional expansion modules include high-pressure automatic cleaning, material temperature monitoring, and variable frequency speed control, adapting to special construction environments such as those with extremely cold or highly corrosive aggregates.

From a manufacturing and compliance perspective, all SICOMA concrete mixers are assembled and shipped according to CE and ISO international manufacturing standards. Key components undergo flaw detection and wear resistance testing before warehousing, and undergo dual testing processes including no-load and loaded trial runs before shipment. Product compliance meets the bidding standards of many countries. Leveraging the advantages of large-scale mass production, this series overcomes the high price limitations of purely imported equipment, combining European technical quality with the cost advantages of localized production.

Looking at global application scenarios, smaller-capacity models are mostly used in rural infrastructure and small precast component plants, while larger-sized MAO3000 and MAO4000 models are used in large-scale environmentally friendly commercial concrete industrial parks and highway and bridge projects. Compared to ordinary domestic twin-shaft concrete mixer products on the market, SICOMA double shaft concrete mixers wear-resistant parts have a 45% longer service life and a 60% lower annual maintenance frequency, resulting in significant advantages in total lifecycle maintenance costs. Leveraging a comprehensive overseas spare parts warehousing and after-sales service system, this series continues to be the mainstream choice for global concrete engineering procurement.
