Efficient crushing and screening processes help produce quality products, Mike Woof reports. Having an efficient crushing and screening operation is crucial to the cost-effectiveness of a quarry as well as providing the best quality product. The crushing circuit is a key component in any quarry with the right selection of equipment as well as effective maintenance important factors in optimising performance.
The new Keestrack B3e jaw crusher is said to be highly versatile and easy to transport between sites. This diesel electric B3e jaw crusher is a hybrid variant of a proven model from the firm aimed at recycling.
The new model retains the advantages of the original track-mounted design but is also said to offer lower running and maintenance costs. The machine is designed to operate either separately or as part of a crushing and screening chain. The firm claims that the design is compact for its output and p
Yanmar’s two latest diesels, the 4TN101 and 4TN107, are said to combine high power density with low fuel consumption. According to Carlo Guidici, sales director for Yanmar Europe: “The engines have 10% lower fuel consumption than the average for the competition.” With power outputs ranging from 90-155kW, the 4.6litre 4TN107 can provide a power density of 33.7kW/litre, which the firm claims is the highest in its class, while it delivers 805Nm of torque.
The issue of power density is important and Guidici
The recycling and minerals extraction markets now share technologies, Mike Woof reports Not surprisingly, the Steinexpo quarrying event in Germany was a key launch venue for new crushing and screening technologies, as well as associated quarrying technology. Crushing and screening equipment firms from a wide range of European countries including Austria, the Czech Republic, Germany, Ireland, Italy, Sweden, Switzerland and the UK were present at the exhibition. However it was noticeable how closely the miner
