Double Shaft Dry Mortar Mixer

The Double Shaft Dry Mortar Mixer is an industrial equipment specialized in mixing building materials such as dry mortar, adhesives and dry powder. The equipment works through two parallel mixing shafts with mixing blades installed on the shafts to mix the materials in an efficient and uniform manner. Its core components include bearings, gearboxes and motors, which work together to ensure stable operation and long life of the equipment. The Double Shaft Dry Mortar Mixer is made of carbon steel or stainless steel, which has high durability and corrosion resistance. One of its design features is that the mixing blades are removable for easy maintenance and replacement. This equipment is suitable for construction sites and mortar production of all sizes.

Improve mixing uniformity
In dry mortar, various raw materials such as cement, sand and additives need to be mixed evenly to ensure that each part of the mixture has the same properties. If the mixing is not uniform, some parts may have different characteristics, which will affect the quality and performance of the final product in construction. The double-shaft design achieves thorough mixing of materials through two counter-rotating mixing shafts, thereby ensuring higher uniformity. Able to achieve a coefficient of variation (CV) of less than 5% in 3 minutes, twin-shaft mixers can reduce differences in material distribution and improve mixing quality.

Faster mixing time
Compared with single-shaft mixers, twin-shaft mixers reduce mixing time, typically by 30% to 50%. This time reduction is due to the strong rotational motion of the twin-shaft mixer through two counter-rotating mixing shafts, which push the material from one side of the mixing tank to the other. This cross-mixing action ensures continuous movement of the material, avoiding lumps and uneven mixing. A typical twin-shaft mixer can achieve uniform mixing in 2-3 minutes, which is particularly suitable for large-scale production needs.

Diversity of material handling 
Twin-shaft dry-mix mortar mixers can handle materials of different particle sizes and densities, including cement-based materials, gypsum, tile adhesives, and thermal insulation mortars. When mixing tile adhesives, fine particles are more likely to clump, which can result in uneven texture if not mixed properly. The powerful hybrid power of the twin-shaft mixer prevents particle agglomeration and ensures that fine particles are fully mixed with other components to obtain a smooth and uniform mixture. Likewise, when handling heavy materials like lightweight concrete or insulation mortar, the twin-shaft design ensures that heavy materials and lightweight additives are mixed thoroughly to avoid stratification. The mixer is able to handle the mixing needs of fine and coarse materials to meet the requirements of different construction projects.

Higher production capacity
Twin-shaft mixers can handle larger batches of material, with many models capable of handling up to 20 tons per hour. In precast concrete production plants, large quantities of dry-mixed mortar are required to manufacture precast concrete elements such as panels and beams. Twin-shaft mixers are able to efficiently provide the required mix, ensuring continuous production without interruptions due to lack of mixed materials. This high production capacity makes it ideal for large-scale production.
