Mineral Dispersion and Wetting Systems

Complete packaged systems for effective slurry makedown of bulk solids and difficult to wet materials. Typical applications include lime, gypsum, starch, talc, bentonite clay, calcined clay, and soda ash.

Lime Slurry System Case Study

Systems includes:

• A semi-bulk bag unloading station with overhead hoist or forklift bag handling.
• Stainless steel hopper with access hatch, to untie bulk bag, includes a dust seal and powder shut-off slide gate.
• Feed hopper with level monitoring, pneumatic vibrator and supported on Vibro-Isolator mounts.
• Volumetric feeder with conditioning auger and variable speed control.
• Complete and effective slurry blending due to pre-wetting and high shear dispersion.
• Multi-tank and dual stage blending on some systems as required.
• Compact system on single mounting skid requires minimal floor space.

Manufacturing:

• Certified welders and welding procedures for all pipe and pressure vessel components.
• All stainless steel construction
• All welded or flanged pipe connections.
• Socket welded control valves and piping components where possible.
  

Control Features:

• An Allen Bradley panel-view operator interface is standard.
• Temperature and mix ratio control loops reside in customizable Allen Bradley PLC program.
• Panel-view screen provides continuous read out of essential process variables.
• Flowmeters monitor slurry, cone water and quench water flows.
• The PLC maintains preset intermediate and final dilution ratios through precise flow rate monitoring.
• Pilot air assisted electrical solenoid valves.

Optional Features:

• Automatic controls to meet unique customer requirements using customer specified components and instrumentation.
