BG OptiFeed - gravimetric weigh feeder for alternative fuels

The world of cement manufacturing is shaped by rapidly evolving technologies, stringent regulatory requirements, and fluctuating market demands. In this environment, efficiency and precision in material handling are essential. The BG OptiFeed gravimetric weigh feeder is an innovative solution designed for the precise feeding and dosing of alternative fuels, delivering exceptional accuracy and reliability — key factors in achieving optimal combustion performance.

FEEDING OF ALTERNATIVE FUEL TAILORED TO YOUR NEEDS

The BG OptiFeed weigh feeder stands out for its exceptional adaptability and customisation options. Whether your operation requires the handling of fine or coarse AFR materials, or even challenging and potentially hazardous substances, the BG OptiFeed series is engineered to deliver. Each model is meticulously crafted to cater to the demand for high efficiency, precise material handling, and adaptability to various production scales, offering a broad spectrum of feeding capacities and precise control over material flow, even to multiple feeding points within the pyro process.

BG OptiFeed ensures reliable and precise fuel FEEDING

At the heart of the BG OptiFeed system lies our commitment to precision, reliability, and safety. With feeding accuracy of up to +/-1% and a feeding range of 1:10, the BG OptiFeed gravimetric weigh feeder ensures optimal fuel feeding. This not only enhances cost and energy efficiency but also supports smoother plant operations by maintaining steady flow rates, essential for optimal combustion conditions.

Furthermore, the accurate control over the fuel mix contributes to lower emissions, aiding compliance with stringent environmental regulations. Designed with safety in mind, the BG OptiFeed includes options for explosion protection, catering to ATEX zones 22, 21 and 20, and ensuring peace of mind in the handling of explosive materials.
