control all crushing, screening, storing and con-veying with real-time accuracy. Maintain maxi-mum production capacity by adjusting process parameters on-line. Original wear and spare parts – using origi-nal wear parts is the key to a successful crushing process. The design of our certifi ed wear parts starts with CAD simulations of the

 — The initial production steps in a quarry operation – drilling and blasting ­– can significantly impact the productivity and costs of most downstream operations, including loading, hauling, crushing and screening, and product yield – the relative volume of high-value crushed stone products versus low-value byproducts.

 — First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less). In addition, the cone crusher will not produce a consistent cubical product, which is a key requirement in many material specifications.

 — The rock-breaking mechanism and effect of confined blasting were analysed by blasting and impact dynamic mechanics, fluid dynamic mechanics, fracture mechanics as well as blasting experiment.

 — In the quarry, crushing is handled in four potential stages: primary, secondary, tertiary and quaternary. The reduction of aggregate is spread over these stages to better control the product size and quality, while minimizing waste.

Crushing and Screening Handbook is an extensive information package for everyone involved or interested in the crushing and screening business. It is made especially for quarry managers but can be beneficial also for others who either study or are interested in the quarrying industry.

 — The goal of the following project was to study the effect of production blasting on loading and hauling times, secondary breaking times and primary crushing times at the Experimental Mine of...

Quarry operators commonly design fragmentation blasts for safety, economy, ease of use at the primary crusher, and even public relations, but they often forget about quality. The blast layout must be properly engineered, documented and adhered to for maximum consistency.
