Soluções de Ponto de Transferência Reduzem a Geração de Poeira em Pedreira

Problema

Uma inspeção Walk the Belt™ da Martin ajudou a resolver problemas com pó em uma pedreira em Iowa.

A quarry in Cedar Rapids was having trouble with fugitive dust. The Health Department was notified of severe dust being blown across the highway into a residential neighborhood. The Health Department set up a dust trailer to measure the dust particles near the residential neighborhood and findings revealed the dust exceeded code requirements. Martin was contacted to help them with their dust issues. Martin scheduled a Walk the Belt™ inspection to see how to solve their problem of dust control. Martin recommended a three-stage process to help them comply with fugitive dust escaping the quarry during operation.

Solução

Martin® ApronSeal™ Skirting is a dual sealing system that prevents spillage without requiring service to maintain.

Stage 1 began with upgrading the transfer point impact belt, which was one of their worst offenders. Martin installed a Martin® Air Cleaner. Then Martin upgraded the transfer point below the crusher by sealing the load zone with Martin® ApronSeal™ Skirting. A Martin® Surfactant Dust System was installed on the crusher dump pocket and feed belt.  Martin then sealed the dump pocket with belting to prevent wind from blowing dust while trucks were dumping loads of rock into the crusher.

Stage 2 included installing a Martin® Air Cleaner on top of the upgraded transfer point capturing fugitive dust from escaping, which was a major cause of dust being blown into the residential neighborhood.

Stage 3 involved installing an additional Martin® Surfactant Dust System on the crusher to complete the dust control management efforts.

Resultados

The Air Cleaner is installed above the transfer to capture airborne dust, collecting particles and returning to cargo.

After completing the installation of all three stages, a meeting was scheduled with the Health Department for a final inspection. Martin walked the health inspector through the three-stage process. The Health Inspector stated, "Crawford Quarry has gone above and beyond the code requirements for dust control. This is awesome. We will be back in one year for another inspection."

A Pedreira Crawford tomou outras medidas para cumprir a queixa, substituindo a unidade de cascalho na planta de cobertura preta por asfalto reciclado nas estradas em toda a pedreira para evitar que a poeira fosse espalhada pelo tráfego de caminhões.
