Producers of construction aggregates, industrial sand, frac sand, and minerals are confronted with a changing business environment relating to materials specifications, production costs, the availabilities of reserves and water, and environmental regulations.
Technologies for construction materials, frac sand and industrial minerals production
PHOENIX Process Equipment Co. offers a broad base of process technologies for construction materials, frac sand, & industrial minerals production and coal tailings dewatering applications. Along with the equipment itself, PHOENIX provides the lab testing, application experience, and process engineering that delivers a total engineered system to the end user.
The PHOENIX Model AS ATTRITION CELL scrubber de-agglomerates raw materials and removes surface contaminants. Features include:
- Powerful, robust gearbox drives
- No pulleys, v-belts or alignment concerns
- Custom designed agitators
- Lower installed power with superior scrubbing
- Compact, robust construction
- High throughputs
- Complete factory assembly
- Optimal scrubbing efficiencies with high slurry densities (65%-80% weight solids)
The PHOENIX Model HS HYDROSORT™ provides sharp size classification, density sorting, and washing/rinsing of granular solids. Precise overflow slurry density tracking and the controlled, flexible addition of upward current water provide easy operational adjustment of the HYDROSORT™ to meet product specifications. The cut size can be varied over a broad size range while density separating lighter weight contaminants (e.g. lignite, shell grit) from sand, or silica sand from heavy minerals (e.g. garnet, Ti/Zr minerals).
The HYDROSORT™ produces high quality, spec sand from variable quality raw material, using a fluidized bed of slurry to classify materials by particle size or density. PHOENIX’s advances in tank design, control instrumentation and sand discharge valves provide superior performance characteristics – a sharper cut, avoidance of channeling behavior, and the ability to operate with ~0-100% mass-yield to the underflow product stream. Typically, mineral slurry is fed into the top of the unit by a hydrocyclone or slurry pump. The feed material encounters an autogenously generated fluid bed formed by particles near the actual separation cut size. The coarse (or heavier) spec product is discharged through automatically controlled valves at the bottom of the unit. Lighter (or finer) particles resist joining the fluidized bed and accumulate at the top of the tank, where they discharge to the overflow launder.
Products for recovery, de-sliming and dewatering sand
PHOENIX offers PHOENIX / KISA Bucket Wheels for recovery, de-sliming, and dewatering sand and other granular materials. Many designs are available with the wheel diameter and bucket width determining the solids handling capacity, while the surface area of the slurry bath defines the hydraulic capacity.
These machines are uniquely designed for solids recoveries of 99%+ with very low power requirements, even from dilute slurries such as dredger spoil. Dewatered solids are readily conveyable and stackable, having residual moistures that are considerably lower than from dewatering screws.
Wheel diameters of over 26ft and widths over 2 x 4.5ft, hydraulic capacities up to 17,500gpm, and solids throughputs up to 1,760 stph are achievable. Residual moistures in the range of 12%-18% can be expected, depending on particle size. The load dependant dewatering wheels typically operate in the range of 0.5rpm to 2rpm. Abrasion resistance is excellent, and the connected power requirement is extremely low, (e.g. installed power of 50hp is capable of dewatering over 1,000stph sand, even from dilute slurry feed).
Slotted elastomer sieve mats for consistent drainage surface area
The wheel is equipped with multiple buckets with the quantity depending on the wheel diameter. Slotted elastomer sieve mats are bolted into the bucket bottoms and provide consistent drainage surface area. In order to further increase the dewatering effect, siphon pipes are mounted beneath the buckets, withdrawing water from the sand "cake" as the bucket lifts from the slurry bath. PHOENIX offers on site field demonstrations for its technologies.
