CHOOSING THE BEST CRUSHING EQUIPMENT FOR LIMESTONE PROCESSING: TECHNICAL AND ECONOMIC JUSTIFICATION OF THE METSO NP1415 MODEL

Abstract

Annotation. The article discusses the properties, applications and technologies of limestone mining, as well as the stages of its crushing - from primary to fine grinding. The calculation of the required productivity of equipment with an annual volume of 800 thousand tons / year was carried out. The choice of the Metso NP1415 impact crusher is justified, its main technical characteristics, energy efficiency indicators and processing costs are given. It is established that NP1415 provides the required productivity, high crushing coefficient and versatility of application in the processing of large limestone fractions.
