Refractory mixers play a vital role in the production of refractory materials.

1. Types and characteristics of refractory mixers

Intensive Refractory Mixers

Intensive refractory mixer have strong stirring capabilities and can achieve efficient mixing in a short time.

It is suitable for mixing various refractory materials, especially for those materials with large differences in particle size, different specific gravity or high viscosity, and show excellent performance.

Intensive refractory mixers usually use advanced stirring technology to produce strong shear, convection and diffusion effects to ensure uniform mixing of materials.

Horizontal Refractory Mixers

Horizontal mixers have large capacity and stable operating performance.

Its stirring shaft is usually arranged horizontally, and the materials are mixed by rotating stirring blades. At the same time, the structure of the horizontal mixer is relatively simple and the maintenance cost is low. Planetary Refractory Mixers

Vertical planetary refractory mixers have a small footprint and are easy to install. Its stirring shaft is arranged vertically, and the materials are mixed by the rotation and lifting of the stirring blades.

The mixing is uniform and the mixing efficiency is high.

The best mixture quality is achieved in a short time.

It is suitable for various amorphous refractory materials and shaped refractory materials. It can also mix well for some special shaped refractory materials, such as rods and tubes.

2. Working principle of refractory mixer

The working principles of different types of refractory mixers are slightly different, but generally speaking, different materials are mixed through a stirring device.

Take the inclined Intensive mixer as an example:

The inclined design of the strong refractory mixing container The mixing container is inclined at a certain angle, which is conducive to the flow and tumbling of materials during the mixing process.

When the mixer is working, the material will slide down along the inclined container wall under the action of gravity, and at the same time, it will be continuously mixed by the action of the stirring device.

The inclination angle can be adjusted according to different material characteristics and mixing requirements to achieve the best mixing effect.

Generally speaking, the inclination angle between 30° and 60° is more common.

High-speed rotation of the stirring device

The stirring device is the core component of the inclined strong mixer. It usually consists of multiple stirring blades and is installed on a high-speed rotating stirring shaft. The stirring shaft is driven by the drive system and rotates at a high speed, so that the stirring blades produce strong shear, convection and diffusion effects on the materials. The shape and arrangement of the stirring blades are carefully designed to effectively mix materials of different particle sizes, densities and properties. For example, some stirring blades adopt a special spiral shape, which can form a complex flow trajectory during the mixing process and improve the mixing efficiency.

3. The importance of refractory mixers Ensure product quality

The performance of refractory materials depends largely on the uniformity of the mixing of raw materials. If the raw materials are not mixed evenly, the product will have problems such as unstable performance and local defects.

Refractory mixers can ensure that different raw materials are fully mixed, thereby ensuring the quality and performance of the products.

For example, in the production of magnesia carbon bricks, evenly mixed magnesia sand and graphite can improve the slag resistance and oxidation resistance of bricks; in the production of high-alumina bricks, evenly mixed high-alumina bauxite clinker and binder can improve the strength and refractoriness of bricks.

Improve production efficiency An efficient refractory mixer can complete the mixing task of a large amount of materials in a short time, greatly shortening the production cycle.

At the same time, mixers with a high degree of automation can also reduce manual operations and improve production efficiency.

For example, some advanced refractory mixers can realize automatic batching, automatic mixing and automatic discharging, which greatly improves the automation level of production.

Reduce production costs Reasonable selection and use of refractory mixers can reduce production costs.

On the one hand, efficient mixers can reduce the waste of raw materials and improve the utilization rate of raw materials; on the other hand, mixers with a high degree of automation can reduce labor costs and improve production efficiency.

In addition, some energy-saving refractory mixers can also reduce energy consumption and further reduce production costs.

In short, refractory mixers are indispensable equipment in refractory production. Choosing the right type of mixer and mastering the correct use method are of great significance to improving the quality of refractory materials, production efficiency and reducing costs.
