CO-NELEMixing & Granulation
Engineered for extreme material abrasiveness, micro-homogeneity, and rapid discharge cycles.
Understanding the physics of high-temperature monolithics, shaped refractories, and advanced ceramic matrix composites.
Refractory castables contain fine ultra-powders (microsilica, reactive alumina) mixed with heavy, abrasive aggregates like fused corundum, bauxite, and silicon carbide. Standard gravimetric or horizontal ribbon mixers fail to deagglomerate fine binder matrix, causing micro-voids and premature thermal shock failure in furnace linings.
Processing synthetic mullite or carbon-bonded refractory brick batches inflicts severe wear on mixing pans. A modern Refractory Mixer Machine must integrate specialized tungsten-carbide hardfacing, high-chrome alloy tiles (HRB > 65), and modular bolt-on wear liners to guarantee 100,000+ batch lifetimes without alloy contamination.
Modern low-cement castables (LCC) and ultra-low cement castables (ULCC) require water additions as low as 3.5% to 5.0% by weight. Standard mixers lead to balling and incomplete hydration. Forced planetary counter-current mixing disperses water molecules instantaneously across dense raw mixes.
Why vertical-shaft planetary motion eliminates dead zones and slashes mixing cycle times by up to 45%.
The mixing blades rotate on their own axes while simultaneously revolving around the central axis of the mixing pan. This dual-rotation vector path ensures that every square millimeter of the mixing pan bottom and sidewalls is swept within 6 seconds. The counter-current shearing force breaks up micro-agglomerates without damaging brittle pre-formed ceramic fibers or steel needle reinforcements.
Unlike standard commercial gearboxes adapted for light concrete, CO-NELE refractory mixers feature custom-engineered planetary reducers designed for high torque shock loads. Operating with high-viscosity refractory slurries or dense resin-bonded compositions requires specialized gear geometry, synthetic oil bath cooling, and reinforced output shafts.

Twin-shaft mixers excel at high-volume concrete ready-mix with standard moisture levels (>8%). However, refractory castables contain dense micro-powders and ultra-low water ratios (3.5%–5%). Twin-shaft mixers create dead zones around shaft ends and fail to break agglomerated micro-silica. Vertical planetary mixers sweep 100% of the pan area with forced multi-directional shear vectors, producing complete binder dispersion and homogenous consistency without trapping air pockets.
For standard refractories, high-chrome cast alloy tiles (HRB > 65) provide exceptional lifespan (up to 100,000 batches). For extreme abrasive materials like fused corundum, silicon carbide, or diamond powders, we recommend modular tungsten-carbide hardfaced tiles or custom ceramic-polyurethane composite liners to prevent metallic contamination in high-purity applications.
Yes. Our laboratory scale models (5 to 75 Liters) utilize identical relative velocity kinematics, blade aspect ratios, and Froude numbers as our production mixers (up to 3,000 Liters). Test results regarding mixing duration, torque response, granule sphericity, and density scale directly to industrial models with a precision within ±3%.
CO-NELE refractory mixers utilize hydraulically or pneumatically driven rotating discharge gates positioned at the center or side of the pan bottom. The ongoing planetary sweep during discharge actively pushes material through the opening, eliminating material stagnation and preventing coarse aggregates from separating from fine powder matrices.
The synthetic oil bath in our heavy-duty planetary reducer should be replaced after the initial 500 operating hours, and subsequently every 4,000 to 5,000 hours (or annually). Visual seal inspection and blade clearance adjustment should be performed weekly to maintain optimal shearing geometry and prevent liner contact.
