SCREENING
Multotec’ s side-tension mats can be installed on existing vibrating screens without structural modifications
media is generally affordable and readily available, it presents several disadvantages.
“ In this case, the woven wire mesh struggled to withstand the impact and abrasion from the product stream, necessitating frequent change-outs- sometimes as often as twice a month. This led to high maintenance costs due to frequent purchases of new mesh; interruptions in production during change-
outs; and increased labour hours and associated health and safety risks. It also led to the potential for entire screen decks needing replacement when small sections of the mesh failed,” says Pieter Uys, Business Development Manager at Multotec.
The mine sought assistance from Multotec to find a more effective solution for their screening needs. After evaluation, they decided to transition from woven wire mesh screen media to side-tension PU mats which are designed for enhanced durability and can be installed on existing vibrating screens without requiring structural modifications.
Says Uys:“ A key aspect of this solution was the custom hand-casting of PU mats to fit the exact dimensions of the vibrating screens, ensuring a precise fit and optimal performance. Additionally, these PU mats offered the advantage of easy installation in place of the traditional woven wire mesh panels, minimizing downtime during the upgrade process. Notably, this innovative approach is applicable across various operations within the sand and aggregate industry, making it a versatile and practical choice for improving screening efficiency.”
Multotec’ s PU mats are also successfully utilised in other commodities globally such as Platinum Group Metals( PGMs), limestone, gold, and coal.
Despite the initial capital expenditure associated with converting to side-tension PU mats, the mine has experienced significant improvements in screening media performance. Since their installation, the PU mats have not needed replacement for over a year; there has been a substantial reduction in maintenance, labour, and material costs; and downtime has decreased significantly, along with fewer health and safety risks related to frequent changes. Furthermore, noise levels have also been significantly reduced, which has led to improved working conditions onsite.
“ The cost savings realised by moving from changing out mesh up to twice a month to not changing the PU mats at all in more than a year are favourable. There have been significant improvements in terms of downtime, labour, and material costs,” adds Uys.
As a result, the mine’ s total cost of ownership for the PU mats has dramatically decreased since their conversion. Additionally, Multotec’ s commitment to customer service is demonstrated through the assignment of a dedicated sales engineer who understands the plant’ s processes, manages stock levels of replacement panels, and can quickly respond to any operational challenges.
