[0002] High-strength wear-resistant castable is a cement-based composite single-component dry-mixed mortar, which is made of high-strength cement, mineral admixtures, high-strength aggregates and anti-cracking and wear-resistant agents through industrial production. High-strength wear-resistant castable can be used by adding water and mixing on site. It has good construction and workability. A certain thickness of anti-wear layer is formed on the surface of the silo or ore trough by artificial plastering. After normal maintenance, it can meet the technical requirements. It has the characteristics of high wear resistance, high bonding strength with the foundation concrete, strong impact resistance, high compressive strength, good durability and long service life.

[0003] After searching, the Chinese patent announcement number is CN219294335U, which discloses a high-strength wear-resistant casting material stirring device. The patent arranges a driving mechanism above the barrel cover of the stirring barrel, and arranges a first stirring mechanism and a second stirring mechanism in the stirring barrel. The driving mechanism drives the first stirring mechanism and the second stirring mechanism to rotate in the stirring barrel. The first stirring mechanism is located in the second stirring mechanism. The material and water enter the stirring barrel from the feed inlet and the water inlet respectively. The driving mechanism drives the first stirring mechanism and the second stirring mechanism to rotate. The first stirring mechanism rotates in opposite directions to the second stirring mechanism, and stirs the mud mixed with the material and water. The material is then subjected to opposite forces in the stirring barrel and is fully mixed. The stirring rods of the first stirring mechanism are evenly distributed and installed on a circular ring, and the stirring blades of the second stirring mechanism are evenly distributed on the stirring shaft. The mud becomes uniform under the repeated rotation and stirring of the stirring rods and the stirring blades, so that the mud can be evenly hardened, its hardening quality is improved, and frequent repairs due to low wear resistance and erosion resistance are avoided, thereby reducing maintenance costs.

[0004] However, during mixing, the high-strength wear-resistant castable may clump, affecting the uniformity of mixing. Utility Model Content
