Title:
鉱物性および非鉱物性材料の粗粉砕および微粉砕のための方法および装置
Document Type and Number:
Japanese Patent JP2010538830
Kind Code:
A
Abstract:
In the coarse and fine grinding of mineral and non-mineral materials, e.g. limestone, cement clinker, blast-furnace slag, old concrete or ashes, the grinding material, usually including new and recirculated stock, is fed as a defined and laterally bounded material layer (4) of predetermined thickness from a material feed container (3), belonging to the comminuting apparatus, by way of a roller-type or rotary-vane feeder (9), which is arranged at the outlet and can be changed in a stepless manner in respect of its rotational speed, onto the vertex of the laterally rimmed (45), driven, bottom roller (1), accelerated to the roller speed and transported continuously into the gap formed (5) with the upper roller (2), arranged in an offset manner above the driven roller (1), is subjected to hydropneumatic loading using specific compressive forces of 2 to 7.5 kN/mm and is then deagglomerated within the comminuting apparatus by a preferably high-speed rotary crusher (10). This results in good utilization of energy and in low mechanical structural, servicing and maintenance outlay. Usage over a wide spectrum for comminuting different materials is made possible, and linear throughput and speed behavior both in partial-load operation and with high mass throughputs can be realized.
