Tricyclic Medium-speed Grinding Mill

Product introduction

​​The three-ring medium-speed micro powder grinding mill is suitable for the ultra-fine grinding of various brittle materials with a Mohs hardness below grade 5.​​ ​​Operating in a closed-loop system, it processes dust-containing gases after dust removal treatment, resulting in no pollution, making it an ideal eco-friendly device.​​

Customer feedback: It creates barely any pollution and boasts high efficiency, often helping our company complete tasks swiftly.​

🔹 Core Technology

​​Tricyclic Gradient Grinding System​​Triple-layer grinding rings create cascading crushing zones (Impact→Compression→Shearing), increasing <45μm particle yield by 30% vs. conventional mills.

​​Intelligent Hydraulic Control​​Automatic pressure regulation (8-18 MPa) adapts to material hardness (Mohs scale ≤7) without manual adjustment.

​​Dynamic Classifier Integration​​Adjustable rotor blades (800-2200 rpm) achieve precision fineness from ​​325 to 2500 mesh​​.

 Application Materials

✅ ​​Minerals​​: Calcite, dolomite, kaolin, barite

✅ ​​Industrial Waste​​: Fly ash, steel slag, desulfurized gypsum

✅ ​​Chemicals​​: Titanium dioxide, precipitated calcium carbonate

​​Extended Wear-Part Service Life​​The grinding rollers and rings are forged with special alloy materials, significantly improving utilization efficiency. Under identical material and fineness conditions, their lifespan is ​​2-5 times longer​​ than impact crushers or turbo mills, typically exceeding ​​1 year​​. For calcium carbonate and calcite processing, service life reaches ​​2-5 years​​.

​​Enhanced Safety & Reliability​​The grinding chamber eliminates rolling bearings and screws, resolving common failures:

No bearing seal wear issues

No machine damage caused by loose screws

​​Finer Output with Lower Energy Consumption​​Compared to traditional Raymond mills, this equipment delivers:

​​Finer particle size​​

​​30%+ lower energy use​​Ideal for dry-process production of ultra-fine heavy calcium powder.

​​High Yield & Energy Efficiency​​At equivalent fineness and motor power, it outperforms:

​​Jet mills​​: +100% output

​​Agitation/ball mills​​: 50% energy savings

​​Pre-Crushing & Feeding​​

Bulk materials are pre-crushed to ≤25mm by a jaw crusher.

A bucket elevator conveys materials to the storage silo.

A vibrating feeder delivers materials ​​uniformly and continuously​​ to the center of the top turntable.

​​Three-Stage Grinding Mechanism​​

​​1st Layer (Coarse Grinding)​​Materials disperse outward by centrifugal force, entering the grinding zone where rollers exert ​​impact-compression forces​​ (pressure: 8-12 MPa).

​​2nd Layer (Intermediate Grinding)​​Partially ground particles fall into finer grinding zones, undergoing ​​shear-rolling actions​​.

​​3rd Layer (Ultra-fine Grinding)​​Final micronization achieves target fineness (adjustable: ​​325–2500 mesh​​).

​​Particle Separation & Collection​​

A ​​high-pressure centrifugal fan​​ generates airflow (25,000 m³/h) to:✓ Transport powder to the ​​turbo classifier​​✓ Separate oversize particles (recycled to grinding chamber)✓ Convey fine powder to ​​cyclone collector​​ (collection efficiency: ≥99.2%)

Residual dust (≤15 mg/m³) is filtered by a ​​pulse-jet baghouse​​ before emission.
