Say goodbye to the industry pain points of uneven mixing and high porosity of traditional refractory materials mixers. Three-dimensional countercurrent mixing technology is reshaping the quality standards of castables.

The latest refractory mixers equipment developed by Qingdao CO-NELE Machinery Equipment Co., Ltd. adopts three-dimensional countercurrent mixing technology, which has completely changed the traditional refractory production process. This innovation achieves uniform distribution of materials at the molecular level by combining horizontally opposed bidirectional impact flows with three-dimensional spatial composite motion.

The core advantage of the equipment is that it solves the problem of unstable castable performance caused by material stratification in traditional mixing processes. After testing, the material uniformity has increased by more than 40%, and the porosity of refractory products has been significantly reduced.

Pain points in the refractory industry
Refractory production has long faced the challenge of insufficient mixing uniformity. Traditional mixing equipment often experiences stratification when processing high-density differential raw materials. In particular, the density difference between basic raw materials such as bauxite and kaolin and additives can easily lead to uneven mixing.

Uneven mixing directly affects the quality of the final product. The local composition difference in refractory castables will greatly reduce the high-temperature corrosion resistance and thermal shock stability of the material, becoming a key bottleneck restricting the quality improvement of high-end refractory products.

Three breakthrough innovations of CO-NELE refractory material mixer:

Industry data shows that the refractory castables produced by three-dimensional countercurrent mixing technology have a 30% higher flexural strength at a high temperature of 1700℃ than traditional products, and the number of thermal shock stability cycles has increased to more than 50 times.
Three-dimensional mixing technology: The refractory material is transported upward by rotating the inclined mixing disk, and the material reaches the mixing range of the high-speed rotor at the eccentric position. Under the action of the rotating cylinder and the high-speed rotor, strong countercurrent shear, convection and diffusion are formed in the three-dimensional space to achieve efficient and uniform mixing.

Efficient mixing: A large amount of mixing work can be completed in a short time. Compared with traditional mixing equipment, the mixing time can be greatly shortened and the production efficiency can be improved.
Good uniformity: The micro powder agglomerates can be completely broken up to achieve molecular dispersion of additives, ensure the uniform distribution of various raw materials, ensure the uniformity and stability of refractory materials, and enable each batch of products to meet the same quality standards.
Multi-process integration: Dry mixing, wet mixing, granulation, surface coating and other processes can be completed in the same container, replacing traditional multiple production lines and shortening the process and production time.

Refractory brick production: Various refractory brick raw materials such as high alumina, silicon, and magnesium can be efficiently mixed, and the raw materials can be made into granular materials that meet the requirements through mixed granulation technology, which is convenient for subsequent molding and sintering processes.
Preparation of monolithic refractory materials: It can ensure that various raw materials are fully mixed, improve the overall performance of the product, and meet the diversified needs of monolithic refractory production.
Production of special refractory materials: It adopts advanced mixing system and granulation system to achieve high-precision mixing and granulation, ensure the quality and performance of special refractory materials, and enhance product added value and market competitiveness.

Mixing of refractory additives: It can ensure that the additives are evenly dispersed in the raw materials, thereby improving the overall performance of the product.

The industry generally adopts the method of extending the mixing time to compensate for the insufficient mixing efficiency, but this brings new problems: increased energy consumption, reduced production efficiency, and premature start of thermal hardening of materials. These problems call for truly efficient mixing technology breakthroughs.
