Sätt och anordning för krossning av material i en krossanläggning med flerstegskrossning

摘要

A method of crushing material in a crushing plant using multistep crushing to form a crushed product. The crushing plant has a first crushing station, an intermediate storage and a second crushing station. The material is crushed at the first crushing station. The amount of material in the intermediate storage is monitored. The degree of reduction at the first crushing station is changed according to the level of material in the intermediate storage. A device for crushing material has a level monitor arranged to monitor the level of material in the intermediate storage. The level monitor is connected to a control unit which is adapted to change the degree of reduction at least at the first of the crushing stations if the level of material in the intermediate storage increases or decreases.
