·?????????The scraper efficiency improved by nearly 17%.

·??????????Spillage cleaning frequency reduced from twice a week to once every 3 weeks.

·??????????Scraper adjustment frequency changed to once every 45 days from once every 15 days.

·?????????The above improvements resulted into substantial annual savings

Features of product –

The advanced technical features of C2 scraper resulted in a superior performance in comparison to the existing scraper. Some of the features are:

·?????????Contact with the belt surface at positive angle in lieu of 90°.

·?????????Overlapped blade modules.

·?????????Unique axial rotation to take care of the unevenness in the belt.

·?????????Unique spring-loaded blade modules for higher contact with the belt.

Reordering of product –

After the performance of C scraper in DPC-1, customer promptly reordered C series scraper for DC-3 conveyor, which faced similar spillage issues. After successful installation of C2 scraper in DC-3 conveyor, customer got similar results and is extremely satisfied.
