Massenza has redesigned its polymer modified bitumen (PMB) mill to deliver improved efficiencies of up to 40%. The manufacturer has made three changes to the previous model in developing the PMB 490-S. “Thanks to three new features, the new PMB mill can improve efficiency by up to 40%,” said director Diego Massenza. The company has changed the configuration of the cutting area, increased the cutting area and modified the inlet for the bitumen polymer. “It needs fewer passages of the bitumen polymer through
Liebherr is working together with Teufelberger to develop a high-strength fibre rope for use with cranes. This innovative rope will be suitable for use in tower cranes, mobile cranes and crawler cranes and Liebherr is carrying out field tests at present on a number of different cranes. Austrian firm Teufelberger is a leader in the field of crane ropes. This project is being carried out jointly between Liebherr engineers from various divisions, as well as Teufelberger.
BHS-Sonthofen’s new vertical shaft impact (VSI) rotor centrifugal crusher (RSMX) offers a throughput rate of up to 580tonnes/hour, depending on the properties of the feeding material and the desired final product.
With TwinDrive for the first time (a double drive), the first delivered machine is said to have proved to be a success in the treatment of gold-containing ores.
A compact rotor with two generously dimensioned centrifugal chambers is mounted on a vertically positioned shaft in the VSI rotor c
