CR24 Intensive Refractory Mixer for Magnesia Carbon Bricks

The CR24 intensive refractory mixer is a high-shear mixing system designed for the production of magnesia carbon bricks and other high-density refractory materials. With an output capacity of 1500 liters per batch, it ensures uniform dispersion of graphite, magnesia aggregates, and binders under demanding industrial conditions.

For refractory manufacturers, mixing quality directly determines brick density, strength, and thermal shock resistance. The CR24 intensive mixer provides controlled mixing intensity and consistent batch performance.

What Makes Magnesia Carbon Brick Mixing Challenging?

Magnesia carbon bricks typically contain:
-High-purity magnesia aggregates
-Flake graphite
-Resin or pitch binders
-Fine powders and additives
These materials present three major challenges:
1. High bulk density and weight
2. Poor dispersion of graphite
3. Strict homogeneity requirements
Traditional low-shear mixers often lead to segregation, uneven binder coating, and unstable product performance.

Working Principle of CR24 Intensive Mixer

The CR24 operates using a high-speed mixing rotor combined with a rotating mixing pan.
This design creates:
-Strong shear force
-Three-dimensional material flow
-Rapid binder coating
-Efficient powder dispersion
Unlike conventional pan mixers, the CR24 delivers controlled mixing energy, which is essential for refractory formulations.

Key Technical Specifications

Why High Shear Mixing Is Critical for Magnesia Carbon Bricks

1. Uniform Graphite Distribution
Graphite must be evenly dispersed to ensure consistent thermal conductivity and oxidation resistance.
2. Complete Binder Coating
Resin must coat each aggregate particle to improve bonding strength.
3. Density Consistency
Homogeneous mixing reduces porosity variation after pressing and sintering.
CR24 ensures stable mixing intensity throughout the batch cycle.

Advantages of CR24 for Refractory Plants

✔ High Batch Stability
Each 1500L batch maintains consistent energy input.
✔ Short Mixing Cycle
Optimized rotor geometry reduces mixing time while maintaining quality.
✔ Long Service Life
Heavy-duty wear liners and reinforced structure withstand abrasive refractory materials.
✔ Adjustable Mixing Intensity
Rotor speed and mixing parameters can be adapted to different formulations.

Typical Application in Magnesia Carbon Brick Production Line

The CR24 mixer is typically integrated into:
-Raw material weighing system
-Intensive mixing system (CR24)
-Hydraulic pressing system
-Drying or heat treatment
Its 1500L output capacity makes it suitable for medium to large-scale refractory plants.
