Venturi eductors, regenerative blowers reliably transport limestone dust at mine

When a limestone mine in Mexico installed dust collectors to contain limestone dust, low-maintenance venturi eductors and regenerative blowers were chosen to convey the dust from the collectors.

Located outside Monterrey in northeast Mexico, INCASA mines limestone, then moves it by truck to a primary hammermill for crushing. A belt conveyor then transports limestone 160 feet at 30 t/h to a secondary hammermill located above a silo. From the silo, limestone loads onto another belt conveyor that transports the limestone 160 feet to a tertiary hammermill above another silo. Finally, limestone is screened to achieve uniform size grades.
