We are looking for rotary drum screens tailored to our specifications. The required treating capacity is 5 m³/hr, with mesh sizes of 1 mm and 5 mm. We prefer an external inflow type and need the screens made from SS316L material with a punch screen design. Additionally, we require a power supply of 415 V, 50 Hz, and an auxiliary slag collection hopper to complement the setup. Please provide your best quote and lead time for these requirements. Thank you!
