  • Patent number: 8778192
    Abstract: A method and apparatus for dewatering a mixture of granulate and water are disclosed. In accordance with one example of the system described herein, the apparatus includes a casing as well as hollow sieve body with side walls formed as a sieve, the sieve body being arranged in the casing and suspended thereto. The sieve body tapers towards the bottom, and a clearance is formed between the casing and sieve body. For delivering the granulate-water mixture an inlet is arranged in the upper part of the sieve body. A corresponding outlet for the dewatered granulate is located at the bottom of the sieve body. The inlet is arranged in the sieve body and the sieve is formed such that the water laterally escapes through the sieve into the clearance due to centrifugal and gravitational forces when passing through the sieve body from top to bottom.
