The inclined Intensive Mixer plays a vital role in the production of the"three major parts"of refractory materials(long nozzle,stopper rod,immersed nozzle),and is one of the key equipment to improve product quality,uniformity and production efficiency.

The following are the core functions and advantages of the inclined Intensive Mixer of refractory materials in production:

Achieve highly uniform mixing:

The three major parts have extremely strict requirements on the mixing uniformity of raw materials(aggregates,fine powders,binders,additives,etc.).Any unevenness may cause weak points,cracks or premature failure of products under harsh conditions such as high temperature,rapid cooling and heating,and molten steel flushing.

The inclined Intensive Mixer of refractory materials combines its unique inclined rotating cylinder and the internal high-speed rotating powerful stirring tool(usually one or more stirring arms/paddles)to produce strong shear,convection and diffusion effects.

This composite motion can completely break up the agglomerated particles,so that the micropowders(such as alumina micropowders,zircon powders,etc.)are fully dispersed and wrapped on the surface of aggregate particles,ensuring that the binders(such as phenolic resins,asphalt,water glass,etc.)are evenly distributed in the material.This is critical to the physical properties(strength,density,thermal shock stability)and chemical properties(corrosion resistance)of the final product.

Handling high-density,high-viscosity materials:

Refractory mixtures are usually dense,and the viscosity increases significantly after adding binders(especially resin-bound ingredients).

The refractory inclined high-power mixer,with its powerful driving power and optimized stirring tool design,can effectively overcome the internal friction of the material,efficiently mix this difficult-to-handle material,and avoid the problems of"shaft sticking"and mixing dead corners that may occur in ordinary mixers.

Improve mixing efficiency:

Compared with traditional wet mills or ordinary dual-shaft/single-shaft mixers,inclined high-power mixers can usually achieve the required mixing uniformity in a shorter mixing time.

Efficient energy transfer:The powerful stirring tool directly applies energy to the material agglomerates to accelerate the mixing process.

Self-cleaning effect:The coordinated movement of the inclined barrel and the stirring tool helps the material to tumble and flow in the barrel,reducing material sticking to the wall and residue.

Optimize particle grading and packing density:

The strong shearing and kneading during the mixing process helps to destroy unreasonable particle bridges and promote the close packing of particles of different particle sizes.

This is very beneficial for improving the initial density of the green body after molding and the volume density of the final sintered product,which directly affects the strength,impermeability and service life of the product.

Improve the effectiveness of the binder:

intensive mixing ensures that the liquid or powdered binder completely infiltrates the surface of each particle to form a uniform coating.

This is essential for the best bonding effect of the binder,ensuring the strength of the green body and the stability during the drying/firing process.Avoid local insufficient strength or cracking caused by uneven distribution of the binder.

Strong adaptability:

It can flexibly adapt to the mixing needs of refractory materials with different formulas and batches by adjusting parameters such as the inclination angle of the barrel,the speed of the stirring tool,and the mixing time.

Reduce dust pollution(partially closed design):

Most inclined strong mixers adopt a closed design,which can effectively reduce the flying of micropowders during mixing,improve the working environment,and meet environmental protection requirements.

In summary,in the production of the"three major parts"of refractory materials:

The inclined Intensive Mixer is the core equipment to ensure the high uniformity of the mixture.This uniformity is the basic premise for manufacturing long nozzles,stopper rods and immersed nozzles with excellent performance,stable quality and long life.

It overcomes the shortcomings of traditional mixing equipment in handling high-density and high-viscosity refractory mixtures.

It significantly improves mixing efficiency and batch consistency.

It lays a good material foundation for subsequent molding(isostatic pressing,vibration molding,etc.),drying and firing processes by optimizing particle grading and binder distribution.

Therefore,in the production line of the"three major parts"of modern high-performance refractory materials,the inclined Intensive Mixer has become an indispensable key process equipment.Choosing a Intensive Mixer with reliable performance and good mixing effect is crucial to improving product quality and competitiveness.
