For industrial filtration, ETP plants, Washing Machines, A disc skimmer is very useful for small tanks with no level variations. Due to robust and simple design it is generally preferred for small individual tanks.
This type of skimmer uses disc instead of belt. The skimmer frame structure is mounted on the top of tank coolant collection tank. A stainless steel disc is dipped in coolant surface from top of the tank. The Disc rotates in clockwise direction. Oily scum adheres to the disc surface and wiped and dumped in scum arresting bin. Disc Skimmers using steel discs of Dia-350MM (Depth 100MM) Model. We also provide Split type using disc Dia-425MM (Depth 250MM) with Chain drive mechanism to split the Disc from motor center to shift the Disc downwards to get more depth using same disc dia. All small models are having built with decanter tray arrangement to further separate the oil from the collect Skimmed mixture and water ETC mixture to return back the coolant, Washing liquid etc. back to the tank. Only pure oil is collected.

Aluminium is vastly used in automobile components. Various operations like drilling tapping on such components generate large quantum of chips. Individual filtration system are prone to breakdowns and do not give required filtration levels resulting in low coolant life.

In a CFS, Dirty fluid along with chips is collected in the dirty tank. This tank has a continuously moving scarper conveyor which removes the chips that settle down. A rotating mesh drum is placed inside this tank. The fluid passes through the mesh drum while the chips are separated on the outside. The filtered fluid drops into a clean tank. Clean fluid pump supply pressurized fluid to the machines. Sizing of the tanks, mesh drum and pumps is done based on your total flow requirement. In addition fine filter housing can be provided for through spindle coolant.

Features & Benefits:

Dirt collected is ejected out automatically with little fluid. Shell of the filter is fabricated in MS & is designed to handle working pressure of filter. Filter elements are SS304 wedge-wire screen candles, mounted vertically with their bottom ends open to dirty fluid & top ends closed.

All candles are exposed to flow of dirty fluid, except one. Dirt is collected inside the candles. One of the candle's outlet is opened to backwash port by aligning rotary face seal to it. Backwash outlet valve is opened for a short time so that the dirt collected in this candle is let out to atmospheric pressure. Since large pressure differential is available between working pressure of filter & atmosphere, backwashing is very effective.

When the preset pressure drop reaches (or time elapsed is complete), the rotary face seal is aligned with next candle outlet & backwash outlet valve is opened for a short time to effect backwashing of that candle. The process is repeated automatically to keep the filter clean & to eject the dirt. A recovery filter is provided to recover fluid ejected along with the dirt. Wedge-wire screen openings, number of working candles, candle sizes can be altered depending on following: Flow & viscosity of fluid, quantity & type of dirt etc.

The filter housing can be designed to handle required working pressure. Filter presently developed has 8 candles, 1000 mm long X 100 mm diameter. It is designed for flow of 8000 LPM (480 m3/hr) of water based emulsion for filtration level of 100 microns. It is going to work as Roll Coolant Filter for a steel cold rolling mill.

Magnetic coolant separator is device which cleans coolant liquid of very fine particles; it removes chips from the milling or grinding liquid. It has light and compact structure having strong magnetic power which can remove very fine particles. For precise grinding operations uninterrupted flow of oil is must. The magnetic separator ensures the uninterrupted flow of the liquid.

A magnetic drum with close dense magnetic field is assembled on non-magnetic SS shaft. Magnetic pole shoes are projected out to form fins”, for better magnetic field alignment around the drum. The drum is rotated very slowly by a geared motor drive.

A non-magnetic SS trough holds the dirty fluid close to drum. Magnetic dirt is picked-up by magnetic field & is attached to the finned drum.

Slow rotary motion dumps the dirt collected on closely contoured scrapers. Extended scraper dumps the dirt collected to a bin. Size & number of fins is selected depending on the flow of fluid, viscosity of fluid & quantum of dirt to be handled. Positive rake scraper is selected for volatile fluid like water based emulsion while negative rake scraping is selected for oils. Negative rake scraper keeps the fluid away from bin.

Features & Benefits:

Band filter are the simplest and oldest form of filters. Veeraja ECO Band filter is one more step towards additional simplicity. This band filter does not have a moving conveyor. This eliminates the maintenance concerns of jamming and breaking of conveyor. A standard magnetic separator can also be added to improve on the efficiency of the band filter.
