W.S. Tyler’s Pro-Deck system is a new approach to maximising a screening system. This approach implements an analysis and modification strategy in processing operations to maximise screen productivity and minimise wear by selecting the appropriate type of screen media according to the three phases of screening. This consultative approach results in a fully optimised screening process for greater efficiency and productivity, as well as less unscheduled maintenance and extended screen life. The Pro-Deck is not based on a canned formula but rather implements a customised approach for each plant’s specific needs. It combines W.S. Tyler’s years of screening expertise with an analytical approach to determine the best mix of screen media for each individual operation.
Traditionally, processing operations tend to use the same screen media on each deck of the vibrating screen. But after extensive research and years of experience, W.S. Tyler concluded that a non-traditional approach of incorporating more than one screen media serves to prevent lost efficiency and unscheduled maintenance. Additionally, the Pro-Deck system helps to eliminate common screening problems such as blinding, pegging, premature wear and unscheduled downtime. Material traveling over a screen undergoes three different phases. W.S. Tyler calls these phases layered, basic and sharp screening phase. With each phase of the screening functioning differently, a customised screen media approach helps tailor the screen media to each phase accounting for the two most important factors in screen media – open area and wear life.
In addition to considering the phases of screening, the Pro-Deck approach also evaluates material characteristics, the current functioning of the plant and final output qualities to ensure the best blending of screen media. Adjustments to the screen media are made one section at a time and results are closely monitored to ensure the highest quality output and maximum productivity. With analysis of material characteristics and adapting the screen media to accommodate wet, dry or even abrasive materials, the Pro-Deck approach becomes a scientific approach to screen media.
The Tyler Pro-Deck approach begins with an onsite visit to the vibrating screen. W.S. Tyler says that “using its self-developed and most modern Vibration Analysis tool available in the market today, its screening experts ensure that the machine is working within operational parameters that cater to the application requirements of the material. The screening expert then determines the critical deck and section(s) within the screen. On the basis of screen performance as well as the wear experienced on the section(s) and deck, a recommendation for screen media modification is made. Upon installation of the new screen media, the results are measured and documented and the focus is laid on the next section(s). This process continues until all recommendations are implemented to the screen. This step by step approach ensures that the customer’s product quality is only positively enhanced and never negatively affected. In addition it allows the customer to verify the new performance and wear advantages continuously.”
The Pro-Deck approach can be applied to any vibrating screen unit in virtually any application. It does not matter whether the screen is under-used, overloaded or screening just about right, the Pro-Deck system has benefits in every situation.
