STARCLEAN® belt cleaners help Sibelco glass recycling facility reduce carryback under main feed belt

Sibelco is a leader in glass recycling. Their facility in Scotland recycles glass waste using a network of 20+ conveyors.

Materials handled on site include mixed bottle and mrph (glass mixed with contamination). These materials are notoriously abrasive and often adhere to the belt, making it difficult to effectively maintain conveyor operation.

Notably, the main feed belt on site is subject to high throughput of mixed bottle and mrph. Together with an ineffective belt scraper, the belt suffered from extremely high levels of carryback, which would pile up under the conveyor. Site staff were required to clean-up these piles daily.

Staff spent hours cleaning under the main feed belt, culminating in 6 wheelbarrows worth of material waste per day. Furthermore, the scraper installed required frequent maintenance and would take 2 hours to back off, clean and reset per week.

To solve the problem, the Maintenance Supervisor contacted ProSpare.

A ProSpare service engineer visited site to assess the facility and scope the problem conveyor.  STARCLEAN® primary and secondary belt cleaners were chosen to combat the abrasive material and high throughput on this belt.

STARCLEAN® primary cleaners provide the benchmark for efficient carryback removal. Abrasion resistant, 85n, modular tungsten carbide blades were selected to provide extra durability.

The secondary cleaner from STARCLEAN®’s 500 series also uses tungsten carbide blades. These are bolted to a reinforced base which is perfect for heavy duty applications. It captures remaining fines of sticky, abrasive mrph and mixed bottle material waste.

Previously, staff would clean up 30 wheelbarrows of material carryback per week. STARCLEAN® has cut carryback by 80%. This equates to a reduction of approximately 1100 wheelbarrows of waste per year. The effectiveness of the scrapers has transformed a once labour intensive daily task into a routine job undertaken as part of regular housekeeping, once a week.

Similarly, the 2 hours a week it used to take to back off, clean and reset the old scraper has been reduced to just 15 minutes with STARCLEAN®. This saves staff over 80 hours each year.

Following the success of STARCLEAN® on the main feed belt, the client installed an additional 18 scrapers throughout the facility.
