These structural improvements allow the PM 521 model to produce 40 to 60 tons of Proler per hour . This device, which can be perfectly integrated with other equipment designed for scrap processing, is primarily required by: Small and large scrap dealers ; Recyclers ; Car wreckers ; Steel mills and foundries .
