METHOD OF THE PEAT FRACTIONATION AND THE DEVICE FOR FRACTIONATION OF THE PEAT Russian patent published in 2006 - IPC B07B7/00 B07B4/00 C10F7/00 

FIELD: peat processing; methods and devices for the peat processing.

SUBSTANCE: the invention is pertaining to the field of peat processing, in particular, to the methods and devices for peat separation by fractions, its aeration and drying. The invention may be used for production of a feedstock at manufacture of the different products on the base of the peat. The method of fractionation of the peat includes formation of a vertical airflow, in which the initial peat is fed, its separation into fractions and transportation of the fractions into collectors. Using a vertical wind flow transport the material into the zone of action of the horizontal air flow. At that the fractionation is exercised under action of the two produced air flows with sedimentation of the fractions in the collectors partitioned by septums, made with the variable heights increasing according to the run of the separable material. The method realized by means of the device includes: the chamber with no less than two collectors partitioned by septums made with the variable heights increasing as moving away from the main ventilating blower forming a horizontal air flow and located in the butt wall of one of the collectors; the blower located under the window made in the base of the indicated collector for feeding of the vertical air flow in the chamber and linked with the hopper of the initial peat by means of the transporter. The technical result of the invention is an increased effectiveness of separation of the peat for fractions and the increased quality of the produced fractions.

EFFECT: the invention ensures an increased effectiveness of the peat fractionation and the increased quality of the produced peat fractions.
