Understanding Magnetic Coolant Filtration

The efficiency and longevity of industrial machinery depend on how well it is maintained. One of the easiest ways to maintain machinery is to keep it clean. Using clean fuel, lubricants and coolants enhance the performance of mechanical equipment. It also reduces the rate of wear of the machine’s components. This minimizes the maintenance costs and reduces unplanned downtime.
Heavy machines use various types of coolants to regulate their operating temperatures. Yet, coolants need filtration systems to eliminate contaminants and maximize their effectiveness. Magnetic filtration is one of the most effective solutions for separating ferrous contaminants from fluid mixtures. Read on if you would like to know more about how magnetic filtration systems work.

How Magnetic Filtration Works

Mechanical processes that involve grinding, milling or cutting metalsproduce waste that often contains fine ferrous particles. These particles can easily contaminate the machine’s coolant fluid and lubricants during cooling cycles.
Metallic particles, though small, are hard and abrasive. They can accelerate wear by brushingagainst the internal components of a machine as they flow in the fluid suspension. The finer ferrous particles can also clog filters, compromise seals and cause extensive engine damage.

It can be challenging to eliminate fine metallic particles using conventional filters. Yet, magnetic filters can eliminate ferrous contaminants from several types of fluid mixtures with minimal effort.
Magnetic filtration occurs when the fluid containing ferrous solids is channelled through a strong magnetic field in the filter. The magnetic field attracts the ferrous particles as the fluid mixture passes through it. Next, a spring-loaded stainless steel scraper discharges the particles off the magnetic surface into a bin.

The Interfil Magnetic Drum Separator

To provide high-quality magnetic coolant filtration services, Interfil developed the versatile Magnetic Drum Separator. Its compact design and robust construction make it ideal for a wide variety of industry applications. Below are some of the features that make the interfil Magnetic Drum Separator stand out.
– Fully automated, self-cleaninggravity-fed system
– Spring-loaded stainless steel scraper blade for discharging waste material
– Compact design suitable for tight spaces
– Robust 127mm diameter stainless steel magnetic drum
– Powerful Heavy Duty multi-pole ceramic grade 8 permanent magnetic circuit
– Driven by a 3 Phase geared motor with a 415V AC power supply.

Top Three Advantages of Magnetic Coolant Filtration

Magnetic coolant filtration has several advantages for its users and the environment. Below are three of its most popular benefits.

High-Quality Filtration

By using a magnetic field to attract the ferrous particles, the magnetic drum separator can achieve sub-micron filtration. This means that it can extract the finest ferrous particles at no extra cost.

Extends Grinding Wheel Lifespan

Fine particles are among the most common degraders of grinding wheels. Eliminating the finest ferrous particles from the coolant fluids allows the grinder to operate in ideal conditions. Frequent coolant filtration reduces the necessity to dress the grinder. With less particulate loading, the grinder requires less maintenance and can last longer before being replaced.

Low-Cost Operation

Since the Interfil magnetic drum separator is fully automated, it does not accrue any additional labour costs. It was also designed to be maintenance-free. Finally, its operation does not require any consumables. As such, this magnetic coolant filter has very low overhead costs and can generate high profits for the industry.
Industrial coolant filtration not only improves a company’s profits but it is also eco-friendly. Filtering and reusing coolants reduces the volume of waste chemicals in the environment. It also saves time and money that could be used for other purposes.
