LOW MAINTENANCE SCREEN MOUNTS FOR EFFICIENCY AND SAFETY IN MINING EQUIPMENT OST-Africa’s advanced screen mount system offers the mining industry a maintenance- free alternative to conventional coil spring mechanisms, ensuring improved performance and greater operational safety.
“T he OST screen
adapter plates, facilitating easy integration into existing installa- tions, without the need for exten- sive structural modification.” OST screen mounts are avail- able in several configurations. The Standard Type (AR/CR) supports vibratory equipment and drive systems, eliminating harm- ful resonant frequencies. The Compact Type (AD/CD) provides high load-bearing capability in constrained installations, ideal for two-mass systems. The Stainless Steel Type (S4) is suitable for operations requiring hygienic or wash-down conditions, while the Suspended Type (AS/HS) is rec- ommended for overhead configu- rations. l
torsional forces compress the rubber components, isolating vibratory motion and eliminating lateral displacement. This method overcomes the limitations of traditional coil springs, which are prone to frequency amplification, fatigue-related failure and safety risks during handling and replacement. “Advantages of OST screen mounts over conventional coil spring assemblies, include simpli- fied installation and greater per- sonnel safety. The rubber-damped design is resistant to corrosion, dust ingress and water exposure, maintaining stable performance in challenging site conditions. Retrofit compatibility is achieved using
mount design - which is based on the Neidhart Concept, originally pioneered
at the University of Pretoria’s Laboratory of Advanced Engineering - addresses long- standing reliability and safety concerns in mining vibratory equipment,” explains Chantelle Scheepers, Marketing Manager, OST-Africa, part of Invicta Holdings Limited. “This highly efficient system features a mechanically advanced design comprising an outer and inner tube separated by four precision- moulded rubber elements. When the inner tube rotates, controlled
