Introduction. The aggregate production industry is a fundamental contributor to the infrastructure and construction sector by providing building materials for road, railways, housing construction, etc. Aggregates production processes are driven by market needs which however may fluctuate during a year, e.g. for the Swedish market, the Annual aggregate production of 416,000 m 3 /year was estimated considering a crushing plant with 200 m 3 /h capacity, southern Ontario,Ontario Geological Survey, Aggregate Resources Inventory Paper 186. 86p.

The paper concerns investigation of the effect of impact crusher operation on selected qualitative characteristics of mineral aggregate products. Qualitative characteristics of crushing products in terms of size reduction ratio and fine particles contents were analyzed from the point of view of operational parameters of the impact Primarily, in-situ rocks are drilled, blasted, loaded, and hauled to the crushing plant for further processes. The results of blasting have been proved to affect every other downstream process leading to the production of various aggregate sizes (Workman and Eloranta 2003; Kim 2010; Tosun and Konak 2015a). Thus, the need to evaluate theEvaluation of blast efficiency in aggregate quarries: facts and

Status of recycled aggregate production facility. Recycled aggregates are obtained by crushing concrete waste in C&D waste. Unlike natural aggregates, the recycled aggregates are likely to contain various foreign substances, and old mortar is adhered to the surface of aggregates, resulting in a large quality deviation (Kim et al. 2019{"payload":{"allShortcutsEnabled":false,"fileTree":{"2022":{"items":[{"name":"1.html","path":"2022/1.html","contentType":"file"},{"name":"10.html","path":"2022/10

The most obvious environmental impact of aggregate mining is the conversion of land use, most likely from undeveloped or agricultural land use, to a (temporary) hole in the ground. This major impact is Run-of-mine ore is usually too large to be useful for construction or metallurgy. Large particles must be reduced to specific sizes to either comply with aggregate sizing regulations, or facilitate mineral liberation; therefore, in the aggregates and mineral processing industries, run-of-mine ore is broken in crushing circuits by cone crushers.A review of modeling and control strategies for cone crushers

Crushing is one of the most energy-consuming technological processes. The purpose of grinding is to achieve the desired grain size of mineral raw materials. The process of grinding consists of many factors, for example, the size and form of crushed grains, as well as their mutual arrangement inside the crushing machine chamber, the The primary objective of this study is to identify key risk factors that affect the aggregate crushing plant. The secondary objectives are: To improve safety and health aspect at aggregate crushing plant. To explore possible hazards that can be occurred. To improve cost of the plant.
