1) Preconditioning (Flocculation):Most applications require the addition of polymers to the slurry prior to dewatering. The addition of these flocculants results in the agglomeration of solids, releasing free moisture. An inline mixer is provided for proper dispersal of polymer into the feed.

2) Feed Distribution: Slurry is fed to a specially designed head box, where the material is evenly distributed for more efficient use of the filtering area.

3)Gravity Drainage: Free moisture is separated from the solids by drainage through the moving filter belt.

4) Wedge Pressure: Material advancing from the drainage zone is deposited into the adjustable wedge zone. Pressure is gradually applied as the upper and lower belts converge to form a cake sandwich.

5)Compression/Shear: The belts follow an S path through a series of compression rollers. Surface pressure created by belt tension squeezes additional moisture from the solids. Simultaneous shearing of material opens additional voids for moisture release. The belts part, leaving a dry cake.

6)Solids Discharge: Cake is separated from the belts by doctor blades and is discharged.

Slurry enters the recessed chamber or membrane filter plates horizontally through a feed pipe at one or both ends of the press. The presses are equipped with a hydraulic power unit, for the automatic control of the opening and closing of the plates. A group of probes located in the filtered water collection channel determines the end of the filtration process. Once the filtration is complete the integrated drip trays open.
The robotic high speed plate shifter, equipped with plate shakers, ensures fast cycle times and complete discharge of even the stickiest material. After the automatic close of the drip tray, a robotic cloth washing system uses high pressure water jets to wash the filter clothes one by one.

AUTO CHEM POLYMER MIXING & DELIVERY SYSTEMS

PHOENIX technologies for liquid/solid separation and slurry dewatering have led the way in mining and aggregates & industrial minerals since 1984. The proper selection, mixing, and delivery of polymers are integral to PHOENIX thickening and dewatering systems. From lab testing slurry samples through recommending and applying specific polymers, PHOENIX is dedicated to engineered process solutions that produce optimum results.

PHOENIX Model D auto/CHEM™ dry polymer mixing & delivery systems are selected to meet required performance parameters with little operator attention and minimum maintenance. Compact, skid mounted packages are available with bag or optional supersack loading. Controls, either automatic or manual, are supplied based on customer preference. Both mix tanks and aging tanks are included in the scope of supply. Model E emulsion polymer systems are available as an alternative when there is a preference for emulsion polymers rather than dry chemicals.

The Model E system includes three stages:

• Water supply components including valves, strainer, booster pump, and flow meter.
• Neat emulsion polymer skid with required valves, strainer, flow meter, and transfer pump.
• Solution mix tank including propeller mixing unit, solution floc delivery pump, and required valves and other in-pipe components.

Features:

• Locally available, generic component parts

AUTO CHEM SYSTEM AUTOMATION & CONTROLS

Our auto/CHEM System Automation responds quickly to varying feed conditions for consistent dewatering performance and overflow water quality. Improving performance while reducing labor input, PHOENIX incorporates sensing, monitoring, and modulating equipment and software into an integral control system that provides maximum flexibility and adaptability.

A properly designed dewatering system converts effluent slurry into a solid phase discharge cake. A sedimentation thickener upstream of the dewatering operation converts the process effluent into a thicker material for more effective dewatering. System operation is optimized and operating costs minimized when the solids feeding the dewatering press are controlled within a pre-defined density range. The components of the PHOENIX auto/CHEM system continuously control the press feed density while minimizing polymer usage.

PHOENIX also can extend our auto/CHEM System Automation for our dewatering plants to more comprehensive process automation and controls. Process automation systems using computer technology and software engineering are frequently used to automatically control various processes in chemical plants, petroleum refineries, pulp and paper mills, and other processing and manufacturing facilities. The plant Process Automation System (PAS) often uses a network to interconnect sensors, controllers, operator terminals, and actuators. Most PAS systems are based on open standards in contrast to Distributed Control Systems (DCS) that are traditionally proprietary. Today, a PAS normally aligns with SCADA systems.

In the absence of process automation, plant operators must physically monitor performance values and the quality of outputs to determine the best settings for optimum equipment operation. Maintenance must be accomplished at set intervals. This generally results in operational inefficiency and sometimes unsafe working conditions. Process automation simplifies this with the help of sensors located at critical points throughout the plant that collect data such as temperature, pressure, and flow rate. This data is stored and analyzed on a computer. The entire plant and each piece of production equipment can then be monitored on a large screen in a control room. Plant operating settings are automatically adjusted to achieve optimum plant performance. Plant operators can manually override the PAS when necessary. Plant managers need for their equipment to deliver the highest output while minimizing production costs. In some industries including oil, gas, and petrochemicals, energy costs can represent 30 to 50 percent of the total cost of production.

Process automation allows computer programs to utilize collected data to not only show how the plant is performing but to simulate different operating scenarios to find the optimal strategy for each piece of equipment. A unique characteristic of this software is its ability to "learn" and predict trends while reducing response times as conditions change. The result is more efficient production, higher outputs, and reduced energy costs. This also ensures consistent product quality and lower maintenance costs from eliminating excessive equipment stopping and restarting caused by unnecessary maintenance.

PHOENIX Process Equipment Co. provides the entire instrumentation and automation package for the dewatering process and works with our customers' engineers and programmers to incorporate this technology into their existing Programmable Logic Controller (PLC) programs. Or, we can provide stand alone loop controls to simply control a portion of the process. We work with our customers to assess what will best fit their needs and their processes.

 

MODEL AS ATTRITION CELL SCRUBBER

 

PHOENIX has served the aggregate industry for over twenty years with its systems for liquid/solid and solid/solid separation, classification, thickening, and dewatering. Adding to its range of separation technology, PHOENIX now offers the ATTRITION CELL Scrubber to de-agglomerate raw materials and remove surface contaminants from sand or other granular materials, featuring:

• Compact, robust construction
• Minimal space requirements
• High throughputs
• Complete factory assembly for ease of installation and relocation
• Over ten years of experience in the field

The Model AS is designed in accordance with CSTR scientific principles of slurry mixing, where mixing intensity can be accurately calculated and cell scale-up (or scale-down) is simple. This allows for the selection of robust , high quality gearbox drives for the agitator configured with twin axial turbines (strong pumping action for keeping large particles in suspension) or axial plus radial turbines (stronger shearing action). The baffled cylindrical cell design minimizes slurry vortexing, back mixing and short circuiting. Cells may be ganged together in flexible layouts to provide the required pulp retention time. Optimal scrubbing efficiencies are attained when the slurry density is very high (typical 65-80% solids by weight).

Features:

• Powerful, robust gearbox drives
• No pulleys, v-belts or alignment concerns
• Scientific "CSTR" design
• Lower installed power with superior scrubbing results

Benefits:

• Baffled cylindrical cell design minimizes vortexes
• Superior control of pulp retention time
• Custom designed agitators
• Optimization of slurry suspension vs. shear

 

MODEL HS HYDROSORT HINDERED SETTLING CLASSIFIER

PHOENIX offers state of the art hindered settling classifier technology. The HYDROSORT™ separates light, deleterious material and classifies sand to suit your exact needs. The controlled and flexible addition of upward current water allows an easy adjustment of the HYDROSORT™ operation to meet customer specification. Both the cut size and cut density can be varied over a broad range.

The HYDROSORT consistently produces high quality, spec sand over a wide variation in raw material quality. The HYDROSORT is a hydraulic classifier and density separator utilizing a fluidized bed of slurry to separate materials by density, or to classify materials by particle size. A mineral slurry is fed into the top of the unit by conveyor belt, hydrocyclone or other means. The feed material encounters an automatically generated fluid bed formed by particles having the actual separation cut size. The spec sand is discharged through automatically controlled valves at the bottom of the unit. Lighter material cannot pass through the fluidized bed and floats to the top, where it is discharged.

Features:

• Automated process control
• Teeter plate or upward current water nozzles
• No moving parts; rubber lining and polyurethane wear parts
• Compact, vertical flow design
• Available in Model C, S or C/S

Benefits:

• Maintains separation/classification efficiency with varying feeds
