TECHNICAL SPECIFICATIONS TYCAN Hydro-Clean High Pressure Washing Technology

 Open the catalogue to page 1

Thank you for your interest in the TYCAN Hydro-Clean. General Information The Hydro-Clean is the latest innovation in washing technology for the mineral processing industry developed based on years of experience in processing plants, systems and components. The first application of the TYCAN Hydro-Clean was for washing aggregate materials. In addition to this conventional application, today there are units in operation within the minerals industry (diamonds, gold, limestone and gypsum| and the recycling industry (building gravel]. Other industries that have demonstrated interest in this technology...

Technical Principal The Hydro-Clean consists of a vertical washing container, which has a feed hopper at its entry and a conveyor belt at its discharge (see Figure 1). This washing chamber is the central element of the Hydro-Clean. It contains a rotating washing head, which is mounted on its top side and consists of several water nozzles. The Hydro-Clean also features polyurethane panels that line the washing chamber, variable height adjustment at the rotary wash head, and the ability to adjust the discharge belt and controlled feeding system based on the bulk material in order to yield optimal...

The Hydro-Clean mode of operation begins with the material being continuously fed by a conveyor belt into the feed hopper (see Figure 2). Small water jets mounted on the side walls of the hopper create a low pressure downstream current, which helps the material, particularly sticky material, to flow into the washing chamber. From there the material falls over a run-in floor into the washing chamber and forms a column of material. The height of the material in the hopper is constantly monitored by a laser level indicator that provides exact data to the PLC unit, which regulates the material flow...

The material is cleaned by being exposed to high pressure streams of water that come from the washing rotor and spray nozzle combination, located within the top third of the cylinder. The nozzles are angled into the direction of rotation of the rotor, so that the water creates a shoveling effect spreading the material. The cleaning process is assisted by friction and shear forces resulting from the material movement around the chamber in a vortex (see Figure 3).

The liberated fines material and process water are discharged through openings in the polyurethane panels lining the washing chamber, and collected by a waste water pipe (located behind the chamber) to be directed to water treatment or further screening. The washed material flows onto the variable speed discharge conveyor and is sent to a washing screen where the dis-agglomerated contaminant material is rinsed off (see Figure 4).

Technical Data and Specifications Currently the Hydro-Clean is available in four different models – HC 350, HC 700, HC 1000, HC 2000. The model numbers are derived from the diameter of the washing drum in mm (See Figure 5). Type Capacity Pressure Electrical PWR Water Req. Length Width Height Weight (Empty) HC 350/200 up to 20 t/h up to 2900 psi 54 HP 27 - 46 gpm 5 ft 3 ft 7 ft 6944 lbs HC 700 up to 100 t/h up to 2900 psi 34 - 79 HP 35 - 50 gpm 8.5 ft 8 ft 10 ft 12460 lbs HC 1000 up to 200 t/h up to 2900 psi 69 - 158 HP 70 - 125 gpm 10.5 ft 9 ft 11 ft 17167 lbs HC 2000 (Twin) up to 400 t/h up to...

The Hydro-Clean as a Complete Wash Plant In several plants the washing stage is performed on wet classifying screens but it is known that the use of spray systems on this equipment operating at 44 - 73 psi (3-5 bar) has a limited effect on sticky material. This practice can only be effective if the contaminant particles are easily removable (fraction between 60 - 2000 pm). The Figures 6 and 7 compare two processing plants, the first one without a Hydro-Clean and the second one with a Hydro-Clean. It can be observed that for the production of 80 t/h and producing the same 5 size fractions the water...

Figure 7 - Flow sheet of a washing plant with a Hydro-Clean Green Benefits In addition to delivering unprecedented degrees of cleanliness and some major technical advantages the Hydro-Clean offers the following green benefits: > Water Consumption - Water is one of the world's most precious resources. Only 0.52 gpm to 1.32 gpm of water is needed to clean one ton of dirt or clay contaminated material. Thanks to the Hydro-Clean's robust filtering technology the water can be re- circulated through a client settling system and requires the addition of only 10% fresh water. This translates into water...

Spare Parts – Since the only “tool” in contact with the material is water, the wear and tear to the unit is minimal. Application dependant, the drum lining needs to be replaced once a year and from time to time the nozzles require exchange. Minimizing the use of spare parts leads to less scrap, less logistical costs and ultimately lower maintenance expenses. percentage < 63µm Ambient Integration – To reduce the impact on the environment it is necessary to streamline systems and make them smaller and more efficient. The standard HydroClean weighs only a total of eight tons compared to traditional...

In addition to its green benefits, this state of the art technology has many advantages when compared with traditional washing equipment: • unparalleled degrees of cleaning as the Hydro-Clean's spray output from the high pressure nozzles are able to penetrate into porous surfaces . wider range of application, as a scrubber cannot accept material < 6.35 mm (formation of clay balls) and a log washer cannot accept material containing more than 15% of plastic and soluble clay < 63um ("lubricating effect ") . less stress on the material, when compared to a scrubber where the material can be damaged...
