CLOSED-CIRCUIT MILLING & CLASSIFICATION ENGINEERING • D7

Hydrocyclone Classification & Roping Diagnostics

Audit your hydrocyclone cluster performance using only 3 Marcy Pulp Density Scale cup readings (Feed, Apex Underflow, and Vortex Overflow) without needing a belt scale or ultrasonic flowmeter.

3-Cup Marcy Mass Balance & Plitt Cut-Size (d50c) Calculator

ZERO BELT SCALE • ZERO FLOWMETER
Optimal Semi-Umbrella Discharge (Stable Air Core)
UNDERFLOW MASS RECOVERY (Rs) 84.2%
ESTIMATED CIRCULATING LOAD 533%
APEX VOLUMETRIC SOLIDS (Cv,u) 48.2%
PLITT CORRECTED CUT SIZE (d50c) 74 µm

Du/Do ratio and underflow volumetric fraction C_v,u within optimal metallurgical window. Maintain preventive Apex gauge checks.

AVENUE 3 · ANTI-BLINDING FINE SCREENING (ARB-SMAT-29)

TH48-30 Fine Urethane Screens & 1'x1' Modular Panels (Weibull α ≥ 4.2)

1. TAPERED RELIEF ANGLE (3°–5°)

Diverging slot geometry that immediately releases near-size particles (0.8 < d/a < 1.2) once past the top throat.

2. ELASTIC DILATION Δa/a ≈ 2%–4%

Flexible urethane membrane under 4–5G acceleration that ejects wedged grains and sustains effective open area A_eff > 32%.

3. WEIBULL PARTITION SHARPNESS α ≥ 4.2

Combining primary hydrocyclone classification with TH48-30 fine screens on underflow eliminates heavy-mineral overgrinding bypass.
