We forcibly mix high-performance mortar, which is difficult to blend with a standard mortar mixer, using a double arm that rotates in reverse!

Our company is a specialized manufacturer of "mixing and delivering" machines for the civil engineering and construction industry, focusing on mortar grout pumps and mortar grout mixers. We offer a wide range of mortar pumps and mixers, providing products that cater to various civil engineering and construction methods. In particular, the 【Cover Link Double Arm Mixer STW-A Series】 is well-suited for on-site mixing of high-performance mortars with low water/cement ratios, incorporating aggregates, special resins, reinforcing fibers, or various admixtures. The counter-rotating double arms forcibly move, shear, and mix the materials!

basic information

Cover Link Double Arm Mixer STW-A Series - Forced mixing with double arms in reverse rotation for hard-to-mix materials! The two arms rotate in opposite directions, ensuring thorough mixing of difficult materials. - Successful miniaturization and weight reduction! By re-evaluating the gear structure, we achieved significant miniaturization and a weight reduction of approximately 42%*2. - Thoughtfully designed blade shape The inner blade shape has been revised to reduce residue around the shaft, achieving uniform mixing. - A wide range of selectable options We offer options that enhance usability, such as "aggregate-compatible blades" suitable for larger aggregates and a "mesh cover" that increases safety.
