Definitions
- the present invention relates to an apparatus for granulometric selection and / or material drying, for the suspension treatment of granular mineral materials of which at least 90% by weight have a size less than 60 mm.
- in-line suspension drying machines which apply to materials having an average particle size of less than 10 mm.
- flash Such systems which are in the form of a development of a vertical pipe of hot gases have been described in publications and in particular B.Reinhardt, Ph.D. Duhamel, R. Evrard, A. Shoemaker - The flash drying - Seminar of the Society of Mineral Industry - Dijon, October 9, 1999.
- the object of the present invention is to provide an apparatus for granulometric selection and / or drying of pulverulent materials, for the suspension treatment of granular mineral materials of which at least 90% by weight are less than 60 mm in size, which operates in line and stably for application to materials with a wide particle size spectrum.
- the invention also relates to a continuous grinding plant, in particular for a cement plant, of closed circuit type, comprising:
- Part of the granular mineral matter, in particular so-called “fines”, can escape with the gas through the upper opening 3 thanks to the lift of the upward flow Fa, while another part of the materials, more coarse, is not driven by the gas and falls through the lower opening 2.
- This device can be implemented with a gas pipe whose length does not exceed 4 to 5 times the value of the diameter.
- the speed of the upward flow of gas can be 15 m / s.
- the topics have a maximum grain size of 100 mm at a specific concentration of between 5 and 6 kg / kg of gas.
- the installation can operate without instability and selects materials such that only particles smaller than about 0.8 mm are flown and particles larger than about 2 mm fall.
- the resulting pressure drop is of the order of 60% compared to the "flash" type drying system known from the state of the art for the same flow of material.
- This facility processes materials 17, 18 at least one of which is wet.
- the plant which processes the materials comprises a grinder 15, a dynamic selector 16, a filter 21 which collects the ground finished product, and material handling means such as a bucket chain or other conveyors, as well as ventilation means for the gases.
- This plant receives hot gases from an undescribed source.
