W.S. Tyler Highlights Mobile Hydro-Clean Washing System
W.S. Tyler will display the mobile hydro-clean washing system at booth 7401 at ConExpo-Con/AGG 2014. W.S. Tyler has added mobility to the list of benefits of its environmentally friendly Hydro-Clean washing system. The company now offers the ability to mount the machine on a chassis for easy movement from place to place within a quarry or even from job site to job site.
Like the original Hydro-Clean, the portable unit effectively cleans deleterious material from aggregate, recycled and other minerals. The results are cleaner products with higher selling value and profits from material that was previously considered waste. In the process, the Hydro-Clean uses up to 75 percent less water than traditional washers and 15 percent less energy. And now, the ability to easily move the units is adding a new dimension of advantage for users, according to the manufacturer.
“The Hydro-Clean is unique in the industry,” said Matthias Bremer, innovation engineer at W.S. Tyler. “Making it mobile delivers the flexibility to locate washing closer to the actual job and reposition it as necessary to boost efficiency, while delivering all the same profitability and environmental benefits of a stationary Hydro-Clean.”
The Hydro-Clean removes silt and clay particles faster than traditional methods, which require soaking the material for long periods to loosen unwanted debris.
The Hydro-Clean also consumes considerably less water. Water consumption ranges from 27 to 211 gal. per minute (GPM) (102 to 798 Lpm), depending on application and model size, compared to log washers that can require up to 800 gpm (3,028 Lpm). Of the total volume of wastewater, up to 90 percent can be recycled and reused in the Hydro-Clean, which only requires 10 percent fresh water to operate effectively. Using recycled water reduces consumption even further, and that can help companies comply with environmental and water usage regulations.
Hydro-Clean units require less energy than other washers, ranging from 34 hp (26 kW) on the smallest of three models to 300 hp (225 kW) on the largest. With that, the HC 350 can process up to 18 tph (16 t), the HC 1000 can process up to 180 tph (163 t) and the HC 2000 can process up to 360 tph (326 t).
Unlike a traditional washing unit, which can require up to three screens along with a log washer or screw, the Hydro-Clean only requires a single rinse screen for discharged material. The only other requirements are a water source, a pump station and a feed conveyor.
The unit comprises a vertical drum-shaped washing container with a feed hopper at its entry and a conveyor belt at its discharge. The washing chamber contains a rotating washing head with several water nozzles mounted on the top of the chamber. It also features polyurethane panels that line the washing chamber and variable height adjustment at the rotary wash head.
The Hydro-Clean is ideal for use in clay-heavy material deposits. Operators feed dirty material into the washing drum through the hopper. The high-pressure water nozzles mounted on the washing head spread and wash the material to break up agglomerates and fully clean even the holes, cracks and deep areas of porous materials, irregular rocks and other stubborn materials.
During the cleaning process, turbulence is created in the drum, providing scrubbing and abrasive forces that enhance the cleaning process. The washed material works its way down the drum and exits onto a discharge conveyor that leads to a standard rinse screen, removing any remaining dirt or clay still on the stone as it fractionates the material. The resulting dirty water flows through the screen media and is collected by a waste water pipe, which sends the water to a treatment system for additional fine screening or discharges it directly to any other area.
Operators can adjust the discharge belt and control the feeding system to accommodate various types of bulk material up to 6 in (15 cm). The distance between the unit's washing rotor and its material bed is variable to allow the system to adapt to various material types. Level sensors located at the material feed inlet provide exact data to the PLC control unit, ensuring a consistent material flow into the system.
The Hydro-Clean also weighs up to 60 percent less than traditional washers with comparable production capabilities. Due to that compact size and weight, the unit is easy to transport and overall operating and structural costs are considerably lower than systems that require more equipment and a larger footprint. Hydro-Clean washing units also feature a maintenance-friendly design that allows for easy exchange of the few standard components that are subject to wear.
