Spring Cleaning!"

New ROSTA AB oscillating mount makes old technology positively prehistoric

DOWNERS GROVE (IL),(PRWEB) October 31, 2003 – No matter what time of year it states on the calendar, it could be time for spring cleaning" in the mining, aggregate and processing industries. Shaker screens play a vital role in all of these operations, yet any piece of equipment is truly only as strong as its weakest part. The weak link common to all shaker screens is conventional spring-mounted suspension. The constant stress can wear out this part all too quickly.
The solution is to fling that spring ¾ remove it and replace it with proven technology introduced by Lovejoy, Inc., in the form of a ROSTA® AB oscillating mount suspension system. This ensures maximum production while promising low maintenance in applications for both screens and feeders.
   Revolutionary in function, this technology is also revolutionary in appearance. Unlike the conventional coil spring, the ROSTA AB consists of two metal squares separated by four cylindrical elastomeric elements, preventing metal-to-metal friction.
   Inherent to the design of any ROSTA part are four elastomeric elements inside the mounting units. These elements transmit the oscillations of any system, while they dampen vibration, shock and noise.
   In addition, ROSTA parts require no lubrication and no maintenance. When used to replace a conventional spring, the ROSTA part guarantees long life, saving operations the cost of periodic replacement.
   In regard to performance, the design ensures the part will possess a natural ability to provide rotary and linear oscillation. The combination of the smooth operation of the unit and the built-in damping characteristic substantially reduces the forces transmitted to the structure.
   Customers can rely on ROSTA AB oscillating mounts for:
Dependable Operation. ROSTA AB oscillating mounts ensure uninterrupted operation. Unexpected failure as with alternative suspension is virtually unknown.
Acoustic Isolation. The special rubber formulation used in ROSTA AB mounts effectively eliminates acoustic noise transmission to supporting structures.

Vibration Isolation. The design of the AB suspension unit provides excellent isolation during the running period of the vibratory equipment. To further enhance vibration isolation, the ESL anti-vibration elements may be used in conjunction with a sub-frame.
Adaptable to Conventional Screens. The ROSTA suspension unit can easily be fitted to most conventional screens. A conversion kit is available for most of the popular screens. These kits are easy to manufacture and drawings are available upon request. In addition, most of the major manufacturers will supply new screens with the ROSTA suspension.
Reduced Operating Costs. The AB mounts provide the user with years of trouble- free operation. Because the suspension system reduces the peak transmitted forces, considerable savings are obtained due to the increase of life of side plates, frames supporting steelwork mechanisms, bearings and v-belts.

Screen Control. One of the major advantages of the system over conventional springs is its remarkable screen control. During the normal running period the AB suspension unit provides a smooth, regular motion in the vertical and longitudinal directions, while restraining sideways sway. At starting and stopping of a screen, the ROSTA unit provides progressive damping, which reduces peak deflections and forces.
Resistance Against Corrosion. Smallest rust films on steel coils define the pre-determined breaking point of the spring suspension. ROSTA AB rubber suspension mounts are corrosion resistant, providing years of service.
