Screw press is a kind of equipment that uses physical extrusion to dehydrate. The material box enters the equipment and is squeezed step by step under the conveying of the screw auger. The excess water is discharged from the liquid outlet through the screen. The discharge port discharges the equipment. The screw press produced by our company has undergone hundreds of accurate theoretical derivation calculations and experimental tests, summed up the real effect feedback of many users in the process of using it for many years, and upgraded it to a series of mature equipment in an all-round way. Different technical parameters can truly achieve low energy consumption, high output, and low moisture, saving a lot of processing costs for the secondary recycling of materials.
