For many years, separating machines have relied on a simple vibrating grille, allowing smaller particles to fall though and retaining larger ones on top. The reason this technique has endured for so long is that it’s undeniably effective. However, it’s a technology that has limitations as it can be subject to clogging and, depending on the material being handled, may lead to some wastage.
Multi Frequency Machines
As a result of newer techniques, one of the most popular and efficient types of separation equipment today uses multi frequency vibration to carry out the process. In contrast to more traditional mesh separators that use a single frequency oscillation, these machines use multi frequency movement to achieve greater acceleration on the mesh, making them much more efficient in operation. Screening mesh is available in a wide choice of different sizes and materials, including nylon and stainless steel. This means that the machines are suitable for dealing with many different materials depending on how they’re specified.
Multi frequency technology is particularly effective with abrasive, wet or sticky materials that have been very difficult to screen using older technology. The change in vibration frequency helps prevent the mesh from getting clogged, increasing productivity by ensuring that the machine doesn’t need to be taken offline for cleaning as often. Side benefits of the technology include reduced wear on the mesh, lower energy consumption and a reduction in wasted material thanks to more efficient screening.
Today’s multi frequency separation equipment comes in rectangular or circular “circus” shapes, making it suitable for a range of different uses. Rectangular types offer greater capacity and have applications in the mining and petrochemical industries. They can be used to separate coal, metal ores, sludge and slurry. They can also be used in the production of aggregates, ceramics, plastics and more.
Double and single deck types are available. Double-deck screens are usually found in heavy applications like screening coal, metal ores and sludge. Single-desk machines are usually found dealing with lighter industrial processes such as powders or slurries.
Circus-type separation equipment can be used to separate fine materials such as powders and metal particles, in addition to slurries and liquids. This means they have lots of uses in the pharmaceutical, agricultural, chemical and food production businesses. Single-deck screens come in a range of sizes, and double-deck versions are also available that offer an increased screening capacity and greater efficiency along with greater mesh life.
Thanks to their versatility, multi frequency screening machines can be found in many different industries. It’s worth investigating the benefits that these systems can bring to your business; savings in energy use, reduced maintenance and less waste are all potential gains.
