# Width of Feed Port and Discharge Port of Impact Crusher

Posted Oct 12 2012 3:00am
 The width of the feed port of the medium and fine impact crusher is represented by the distanced of the upper end of the two cones when the movable cone is used to close to the fixed cone. The width of the discharge port of the impact breaker is represented by the distance of the lower end of the two cones when the movable cone is used to close the fixed cone. The selection of the width of the feed port and the discharge port is related to the feed size and the discharge size. The maximum feed size is determined based on the ore beneficiation process. The width of the discharge opening depends on the product size required. For the medium and fine impact crusher, the width of the discharge port should have a adjustment range for the requirements to crush the materials with various hardness. For the materials with different hardness, the discharge oversize particles coefficient is different. For the medium impact crusher, the discharge oversize particles coefficient should be 2.4 when it is used for crushing the hard materials. The discharge oversize particles coefficient should be 1.9 when the impact crusher is used to crush the materials with medium hardness. The discharge oversize particles coefficient should be 1.6 when the impact crusher is used to crush the soft materials. When you determine width of the discharge port of the medium impact crusher, you must consider the impact of the large particles on the feed size of the fine impact crusher, because there is often no screening device of the medium impact crusher. The width of the discharge port of the fine impact crusher is often equal to the particle size required. You need not consider the large particles problems. The eccentric distance is denoted by r. The size of the eccentric distance is different from the spherical center to the various horizontal plane. Usually, the eccentricity distance means the swinging stroke of the moving cone axis in the plane of the discharge opening. If the moving cone revolves one circle, the swinging stroke of the moving cone axis is 2r. The eccentricity distance and the swinging stroke of the dynamic cone of the fine impact crusher can be calculated out through certain geometric relationship.We provide Professional technology, excellent product quality and intimate after-sales service when you purchase Vibrating feeder, China mobile crusher, from our company.As a professional mining machinery exporter, we will win your trust with our delivery speed, Enterprises Credit and product quality.
