【 摘 要 】

The paper presents study on the working chamber size influence on the technological and economic effectiveness of mineral material grinding in electromagnetic mill. Performance at desired throughput and technological effectiveness is the key issue for the processing apparatus application in the specific technological circuits. The problem of process effectiveness assessment for the specific mill's construction is important for the grinding circuit design and the process operating points' selection. It also allows for the proper control system design and the process optimization according to the specific criteria function. The research with electromagnetic mill was performed in order to assess the influence of the physical parameters of the mill's working chamber on the grinding process effectiveness. Quality factor was based on the chosen grain size fraction increase in the final product. Experiments were performed on electromagnetic mills with the working chamber diameter 200 mm and 320 mm respectively.
