Map your grinding classification, flotation, or filtration equipment and wear parts with 1:1 dimensional verification in Durango.
1. Mill Discharge Sump
Surge feed variations, high startup torque, and coarse solids turbulence.
Horizontal centrifugal slurry pumps with wet-end wear parts in High Chrome, Rubber, or Polyurethane and 1:1 dimensional verification in Durango.
Process Inputs: Design flow rate (m3/h), total dynamic head TDH (m), slurry specific gravity (SG 1.1 to 1.7), d80 particle sizing (microns), and mine elevation above sea level.
Metallurgy Rule: Specify drive train with minimum 1.35 service factor. High Chrome A05 for coarse angular slurries; vulcanized rubber for fine solids under 5 mm with flotation reagents.
Risk Prevented: Prevents skid torsional vibration, shaft deflection, and premature bearing overheating under slurry surge startup conditions.2. High-Head Slurry Impeller (Closed / Wide-Passage)
Severe impact wear from silica solids and loss of classification head.
650+ HB white iron with dynamic balancing on Durango test bench.
Process Inputs: Slurry specific gravity (SG), solid concentration by weight (Cw %), d80 particle distribution, and operational slurry pH.
Metallurgy Rule: A05 (650+ HB) mandatory for quartz or silica over 35%. Vulcanized natural rubber mandatory for pH under 4.5 or sodium cyanide solutions with fine solids.
Risk Prevented: Prevents accelerated clearing back-vane erosion and premature pressure loss to classification hydrocyclones.3. Volute Liners, Throatbushes & Frame Plate Liners
High risk of cutwater perforation and unplanned grinding circuit shutdown.
Reinforced liner wall thickness in High Chrome, Rubber, or Polyurethane for extended campaign run-time.
Process Inputs: Discharge peripheral velocity (m/s), piping configuration, top particle size (mm).
Metallurgy Rule: Reinforced cutwater thickness. In slurries with oversize rocks over 12 mm avoid rubber; deploy heavy-section High Chrome A05 alloy.
Risk Prevented: Prevents split-casing breakthrough perforation and uncontrolled slurry containment spills in plant sumps.4. Centrifugal Expeller & Stuffing Box (No Mechanical Seal)
Lack of high-pressure gland seal water and bearing slurry contamination.
Dry centrifugal expeller and braided PTFE/graphite stuffing box (we do not sell mechanical seals due to severe slurry abrasion and corrosion).
Process Inputs: Suction pressure (bar / psi), gland flush clean water availability at positive head, and frother chemical content.
Metallurgy Rule: High Chrome A05 centrifugal dynamic expeller when gland flush water is unavailable in sumps; braided PTFE/graphite stuffing box when positive-pressure gland water is available (no mechanical seal).
Risk Prevented: Eliminates shaft sleeve scoring and bearing contamination caused by slurry ingress through the stuffing box.1. Flotation Cell Mechanisms & Pulp Conditioners
Heavy solids sanding at cell bottoms and drive shaft/head wear.
Drive heads, shafts, air standpipes, and agitation mechanisms for Rougher, Cleaner, and Scavenger banks.
Process Inputs: Daily processing throughput (t/d), slurry solids density (%), target kinetic residence time (min), and bank role (Rougher/Scavenger/Cleaner).
Metallurgy Rule: Structural plate tank (6 to 10 mm) with hot-vulcanized internal abrasion rubber lining. Dart valves with pneumatic or manual positioning.
Risk Prevented: Prevents heavy solids sanding at tank bottoms and premature froth weir erosion due to pulp turbulence.2. Flotation Impellers, Diffusers & Wear Spares
Stator finger chemical corrosion and loss of bubble generation capacity.
4140 quenched and tempered steel shaft, heavy bearings, and anti-cavitation dispersers.
Process Inputs: Cell volume (50 to 300 ft3), rotor angular tip speed (RPM), motor installed power, and collector/frother chemistry.
Metallurgy Rule: High-modulus molded rubber rotor and stator disperser over steel cores. Quenched and tempered alloy shaft with double spherical bearings.
Risk Prevented: Prevents drop in air dispersion, short-circuiting, and metallurgical recovery losses from worn disperser fingers.1. Recessed-Plate Filter Presses (800 mm to 1500 mm)
High cake moisture, long cycle times, and process water loss.
16 bar electro-hydraulic closing with polypropylene plates for concentrates and dry tailings.
Process Inputs: Slurry feed volume (t/h), initial solids percentage, and target cake residual moisture (< 15% for geotechnical dry stacking).
Metallurgy Rule: Recessed chamber and membrane squeeze plates for secondary compression. 10 to 16 bar filtration pressure with heavy-duty structural sidebars.
Risk Prevented: Prevents wet unstable filter cakes unsuitable for dry stacking and excessive cycle discharge downtime.2. Filter Plates, Cloths & Pulp Density Scales (Marcy Type)
Cloth blinding from clay fines and direct on-site measurement of % solids in slurry.
16 bar rated plates and cloths, plus Marcy-type scales with 1000 cm³ container and 12 interchangeable dials.
Process Inputs: Plate dimensions (800x800 to 1500x1500 mm), slurry pH, operating slurry temperature (°C), and required cloth permeability (L/dm2/min).
Metallurgy Rule: Monofilament polypropylene cloths with heat-sealed borders for abrasive tailings; multifilament weave for fine flotation concentrates.
Risk Prevented: Prevents premature cloth blinding, filtrate turbidity leaks, and peripheral plate edge weeping.Request a Quotation for Mechanisms or Conditioners
