摘要： A device for producing granules has a water-cooled granulating mechanism for producing plastics material granules. A discharge line arranged downstream of the granulating mechanism discharges a starting mixture flow and a granule heat exchanger arranged downstream of the discharge line controls the temperature of the mixture containing the plastics material granules and cooling water using parallel fluid passages. The granule heat exchanger has an inlet and an outlet for a transmission heat exchanger medium. A drying mechanism arranged downstream of the granule heat exchanger dries the plastics material granules. The device also may have an energy recovery mechanism arranged downstream of the discharge line for recovering energy from a recovery cooling water flow, containing at least a part of the cooling water of the starting mixture flow. The device uses waste heat, transmitted to the cooling water to increase the performance of the device and improve the energy efficiency thereof.

摘要： In a process for making plastic granulate, a polymeric material is plastifyed into a plastic mass which is divided into single plastic strands. After pressing the plastic strands in a stream of cooling liquid, the plastic strands are shredded in the cooling liquid into granules, thereby forming a dispersion which is conveyed through a first conduit to a separator. The dispersion is concentrated in the separator by withdrawing a portion of cooling liquid, and subsequently transported to a dryer along a second conduit which is longer than the length of the first conduit. In the dryer, the cooling liquid is separated from the granulate.

摘要： In a process for hydraulic transport of bulk material from a receiving site to a remote location via a conveying pipeline, a dispersion is prepared from bulk material and a liquid, and conducted into a feed pump which has a pressure side in communication with the entry into conveying pipeline, whereby a fraction of the liquid is withdrawn at a location between the pump and the entry into the conveying pipeline. Suitably, either the volume flow of the withdrawn fraction of the liquid represents a manipulated variable which is changed in dependence on a controlled variable constituted by the volume flow through or pressure in the conveying pipeline, or/and the dispersion is produced upstream of the feed pump from a controllable bulk material stream and controllable liquid amount, whereby the amount of liquid may also include at least a fraction of the liquid withdrawn from the pressure side of the feed pump.
