Optimising blasting for increased saleable
I believe that rock is best broken in the pit. Every ton of rock which goes through comminution adds cost and generates waste. At this quarry, I have seen the final stage Crushers are machines used to reduce the size of rocks, stones and ore. They are often utilized in aggregates production, construction material recycling and in mining Crushers All crusher types for your reduction needs TON

Blasting Fragmentation Study Using 3D Image Analysis of a Hard Rock
This article presents a study of the rock fragmentation optimization of very compact itabirites, based on four blasting tests, performed in a different way from the conventional blasting design. The fragmentation analysis was performed using the PortaMetricsTM tool, and compared with the Kuznetsov and Rosin–Rammler particle The aggregate production step comprises blasting, a vibration feeder, a primary crusher, a Figure 10 shows the bench blasting design applied Ko, Younghun, Chanhwi Shin, Youngjun Jeong, and Sangho Cho. 2022.

Evaluation of blast fragmentation effects on jaw crusher
Abstract. The fragmentation rate and particle size distribution of the muckpile after blasting have important influences on the performance of subsequent mining activities such as loading, hauling, crushing, grinding, and the overall costs of the mine. Drilling and blasting are important steps in the chain of mining processes, and its resultsMajority of the world's mine production is made by surface mining facilities for various reasons. Use of explosives is the most economical way in loosening of the main rock where hard rock formations exist. The degree of fragmentation affects the subsequent excavation and loading operations as well as indicates the success of the blasting Practical Measurement of Size Distribution of Blasted Rocks

Introduction. Gomes Sand is a quarry operation that has been in operation since 2009, producing sand and stone for the construction industry. The quarry was experiencing unacceptable blasting results. The repercussions included uneven pit floors, large amounts of oversize rock (>500 mm), and inconsistent fragmentation.189 Effect of Drilling and Blasting Performance on the Energy Consumption of a Jaw Crusher In calculations, each truck is assumed to be about 30 tons and the energy consumption ofEffect of Drilling and Blasting Performance on the Energy
