FLOCCULANT

Serving best-in-class solutions, products, and services for construction, infrastructure, mining and aggregates, and waste water management Since 2023

Chema Engineers Crushing and Mining Solutions Pvt Ltd supplies Chemfloc Series high-performance flocculants designed for mineral processing, washing, and industrial water recycling. Our flocculants are engineered to work seamlessly with Chema PU dewatering screens, hydro-cyclones, and thickeners to maximize water recovery and solids capture.

Chema Engineers Crushing and Mining Solutions Pvt Ltd supplies complete automatic flocculant preparation and dosing systems to work with Chemfloc 1.1 -- 1.4 grades. The system ensures proper hydration, aging, and precise dosing to your thickener, or clarifier.

Key Features & Specifications

1. Physical Form: White granular powder, 98%+ active content
   - Fast dissolving, no fisheyes with proper make-up system
   - Bulk density: 0.7–0.8 g/cc

2. Solution Strength: Make-up at 0.1%–0.25% concentration
   - Aging time 30–60 min for full activation

3. Dosing Range: 10–60 g/t of dry solids depending on application

4. pH Range: Chemfloc 1.1–1.3: pH 6–10 optimum.Chemfloc 1.4:pH 4–8

5. Temperature: Effective from 5°C to 60°C process temperature

6. Shelf Life: 24 months in sealed bags, cool dry storage

Performance Benefits

1. Rapid Settling: High MW grades achieve 3–8 m/hr settling rates in thickeners

2. Clear Overflow: <50 NTU overflow turbidity, suitable for direct reuse

3. High Underflow Density: 55–70% w/w solids in thickener underflow

4. Dewatering Boost: Improves cake solids by 8–15% on PU dewatering screens

5. Low Consumption: Optimized charge density reduces dose vs generic flocculants

Applications in Mineral Processing

1. Iron Ore Beneficiation: Chemfloc 1.2 for tailings thickening. Pairs with 0.3mm PU dewatering mats to achieve <12% moisture

2. Coal Washeries: Chemfloc 1.1 or 1.4 for fine coal recovery. Used before PU dewatering screens and screen bowl centrifuges

3. Sand & Aggregates: Chemfloc 1.1 in sand screw + PU dewatering screen circuits for +90% water recovery

4. Base Metal Concentrators: Chemfloc 1.2/1.3 for Cu, Pb, Zn tailings. Reduces load on TSF

5. Industrial Effluent: Chemfloc 1.3 for ETP clarifiers – clay, pigment, ceramic wastewater

Why Chemfloc with Chema water recycle systems?

1. Circuit Optimization: We test your slurry and match Chemfloc grade + Thickener for lowest total cost

2. Reduced Blinding: Right floc size prevents ultra-fines from blinding 0.25–0.5mm PU dewatering mats

3. Water Balance: Chemfloc + Thickeners recover 85–95% process water vs 60–70% with no flocculant

4. Lower OPEX: 15–30% lower flocculant consumption vs commodity grades due to high activity

5. Single Source: One partner for wear parts + process chemicals = better accountability.

Supply & Technical Support

1. Packaging: 25 kg bags, 750 kg jumbo bags. Bulk tanker for large plants

2. Make-up Systems: We supply auto flocculant dosing plants 100–5000 L/hr

3. Lab Testing: Free jar test + settling test to select grade and dose

4. Plant Trials: 1 MT trial lot with our engineer on-site for optimization

5. Stock: All 4 grades kept in stock at our works for urgent dispatch

Why Use an Automatic Dosing System?

Manual batching causes inconsistent concentration, fisheyes, and wasted flocculant. Our system gives:

1. Consistent 0.1–0.25% solution strength – no over/under dosing

2. Full polymer activation – proper wetting + aging = 20–30% lower consumption

3. Continuous operation – matches plant flow variations automatically

Key Features

1. 3-Tank Design: Prep → Aging → Dosing. Ensures no short-circuiting of unaged polymer

2. Dry Powder Handling: Dust-free loading via bag dump station or bulk bag unloader

3. Auto Concentration Control: Load cells or powder flow meter + water flow meter maintain set %

4. Flow Pacing: Dosing pump VFD linked to thickener feed flow meter for g/t control

5. Anti-clogging: Low-shear agitators at 30–60 RPM, smooth tank interiors, no dead zones

6. Post Dilution: Inline static mixer adds dilution water before injection point

Integration with Chema water recycle solutions

1. Thickener Feed: Dose Chemfloc 1.2/1.3 in feed well for max settling rate

2. PU Dewatering Screen: Secondary dose point at screen feed box to build stronger flocs = drier cake on 0.3–0.5mm PU mats

3. Cyclone O/F: Small dose to aggregate ultra-fines before clarifier

Benefits vs Manual Batching

1. 15–25% less flocculant due to 100% activation

2. Stable operation: No process upsets from concentration swings

3. Labor saving: 1 shift check vs continuous manual mixing

4. Better water quality: Consistent o/f clarity = direct reuse

5. SCADA Ready: 4-20mA, Modbus for plant DCS integration
