Like air classification, screening or sieving involves the separation of dry granular solids according to particle size. Screening equipment is used in almost every process that handles dry particulate matter. Screening requires relative motion between the sieve and the particle mass. In a few specialized cases, the sieve is stationary, but in ...

The spiral classifier is based on the principle that the size and specific gravity of solid particles are different, so the settlement speed in the liquid is different. Fine ore particles float in the water and overflow, and coarse ore particles sink to the bottom of the tank and are pushed up by the screw for mechanical classification.

Abstract. Participants in an asynchronous conversation (e.g., forum, e-mail) interact with each other at different times, performing certain communicative acts, called speech acts (e.g., question, request). In this article, we propose a hybrid approach to speech act recognition in asynchronous conversations. Our approach works in two main steps: a long short-term memory recurrent neural ...
