Traditional wire mesh screens are a nightmare to change. Doing so typically takes three people, a sledgehammer, a crowbar, and a lot of elbow grease. While that switch is happening, your entire operation grinds to a halt. This state of inactivity can persist for what feels like days as technicians fight with worn-out screws and jagged edges. And, in mining more than most industries, time is money. Fortunately, a modular screening panel system makes swapping out broken media less of a nightmare and more of a mild inconvenience.

If you’ve ever harvested potatoes, you know that root crops are a messy business. While getting the vegetable is easy, you must dust off rocks, dirt clumps, and bits of earthworms before you can eat it. This cleaning process is often just as—if not more—strenuous than the harvesting itself.
Finding that perfect combination of truck and blade wasn’t easy, but you managed. Now, you’ve got to put some teeth on that plow. Since you’ll be doing a lot of work in residential areas, steel and carbide edges are out of the question. They’re rough on roads and too loud for regular use. So, you’re down to two options: rubber and polyurethane.
Polyurethane gaskets provide exceptional bonding capabilities, strong weather resistance, and extremely slow degradation. These gaskets will be resistant to moderate chemicals, oils, hydrocarbons, greases, fats, and ozone.
The impeller is arguably the essential part of your centrifugal pump, and slurry applications can be particularly hard on it. Because of the abrasive nature of the slurry, it’s critical that you choose the right impeller so you can operate effectively without constant breakdowns.
Because of its numerous advantages, polyurethane has become the go-to material for production line rollers. In today’s piece, we’ll explore why that is and learn a bit more about how rollers help the world go round.
It’s an item that isn’t well known outside of the industries that use pipelines to move their products, but within them, polyurethane pipeline pigs—or “Poly Pigs” as they are often called—are an essential part of their operations. With slightly oversized diameters, the pigs can remove all sorts of debris, such as loose sediment, product buildup, and foreign matter, to help increase a pipeline’s carrying capacity and improve product quality.
New cars seem to float on the road, making every bump and pothole feel like an afterthought. Wanting to keep that magic carpet feel, you get your car serviced at every opportunity. But, even with that new car air freshener and routine maintenance, it soon loses its smooth gait. Before long, you can feel every divot in the road. In most cases, a worn-out bushing is to blame. If it’s time for new bushings, you need to ask yourself one thing: rubber or urethane?
A spider coupling is a power transmission coupling that can also be used in motion control applications, for example, a motor. It connects two shafts while minimizing vibrations and compensating for any parallel, angular, and axial misalignment.
It’s one of the primary causes of downtime and lost production in the screening process. It’s officially called “blinding” in the mining and aggregate industries, and it happens whenever the screen mesh openings are blocked by the material that is being screened.
Poly-Tek manufactures impact bars designed to prevent belt damage and offer much-needed impact and wear resistance. Without the help of these bars, maintenance expenses for both the bed and the belt would be substantially higher.
You can’t minimize the importance of the milking liner. After all, it’s the only part of the milking machine that comes into direct contact with the cow’s teats. That alone is enough to make it a vital component in the process of milking cows swiftly, gently and thoroughly.
Mining operations have been using woven wire cloth screening products for many years with satisfactory results. Certain operations that experience unusually high wear and require frequent screen replacements, however, should likely be considering engineered screen media. Rubber and polyurethane panels are two materials that have been shown to handle abrasive or heavy materials more effectively than woven wire.
There are different types of seals used in a mill liner fastening system. For enlarged or elongated bolt holes, there are cone repair seals in diameters of 1″ through to 2″. A repair seal includes a cone that extends through the grinding mill shell, whereas a regular seal does not have a cone.
Poly-Tek manufactures and sells a variety of rubber parts for nut industry. One of those parts is the shaker pad. Rubber tree shaker pads are used to shake the trunk of different types of trees including almond trees, pecan trees, walnut trees, pistachio trees, olive trees, cherry trees, etc.
Poly-Tek has been manufacturing the best rubber and polyurethane engine mounts for over 60 years. Rubber and polyurethane are used in many automotive applications because of their excellent reversible elastic deformation properties and excellent damping and energy absorption characteristics. There are advantages and disadvantages between the two types of mounts, which we will discuss below.
