New AI classifier for indicating AI-written text

Our classifier is a language model fine-tuned on a dataset of pairs of human-written text and AI-written text on the same topic. We collected this dataset from a variety of sources that we believe to be written by humans, such as the pretraining data and human demonstrations on prompts submitted to InstructGPT.We divided each text into a prompt …

Air classification

Air classifiers have two basic types: simple expansion chambers, such as cyclones; and centrifugal force-based air classifiers, such as the Mumford-and-Moodie type patented in 1885 or the Whirlwind-type separator. Cyclonic air classifiers use a high-speed rotating airflow to create the force fields within a cylindrical or conical container ...

The feed rate of the air classifier is in range between 2 and 6 kg/h, which is the function of bulk density. Rotor speed varies between 2500 and 15,000 rpm and air flow rate is in range between 5 and 30 m 3 /h. The target size of the classification can be adjusted with the air flow rate and rotor speed.

AIR CLASSIFIERS – Van Tongeren

Van Tongeren developed three models of air classifier in 1958, using knowledge of air flow gained through the earlier development of cyclones. The equipment is used to classify particles into different size ranges (as opposed to a cyclone, which is designed to collect particles of all sizes). The three models were the gravitational, the ...

A new volute design method for the turbo air classifier

Abstract. Volute profile plays an important role in guiding the airflow for a turbo air classifier. The traditional volute design is based on the method of analogue and there is a lack of uniform theoretical design basis and guidance. To meet the needs of guiding the airflow better, a logarithmic spiral volute design method is put forward …

Air classifiers

Gravitational air classifiers. With the use of air flow, gravity and sharp directional changes, the gravitational classifiers perform accurate separations of material from 1,700+ microns down to 150 microns. Coarse particles are conveyed by gravity through a valve at the bottom of the unit, and fine material is conveyed by air to a fabric filter.
