Material reduction process in Mexico

A quarrying operation in Mexico has switched to using a drum cutting attachment supplied by 283 MB Crusher, instead of using explosives for blasting. The customer says that this change in working operations has delivered major benefits in terms of efficiency. The company is now able to deliver a more consistent grade of material in terms of both quality and size. Using the drum cutter attachment ensures that there are lower waste fines produced, as well as no over-sized material requiring secondary breaking at additional cost.

West Africa’s biggest bitumen plant

July saw the ceremonial sod cutting for a project to build West Africa’s biggest bitumen plant: a joint venture between Ghana’s oil company GOIL and Societe Multinationale de Bitumes (SMB) of the Ivory Coast. The project, which will cost around US$35 million according to GOIL, is in Tema Ghana. With a capacity of 8,000tonnes, it will produce AC10 and AC20 bitumen and polymer modified bitumen (PMB). Speaking at the ceremony, Ghana’s minister of energy John Peter Amewu said: “Due to the success of the PMB

Iterchimica’s cross-linking agents boost PMB performance

Cross-linking agents can vastly improve the stability and performance of polymer-modified bitumen (PMB), according to additive specialist Iterchimica. Modified bitumen can become unstable when it is stored inside a tank because the polymer rises to the top, meaning that the rheological behaviour of the bitumen varies through the tank. Cross-linking agents modify bitumen through a chemical action that stabilises the bitumen inside the tank to create a homogenous PMB and hence, a homogeneous asphalt concr

Adhesiveness control in asphalt mixes – from the project to production

Asphalt plant producer Ciber discusses asphalt mix properties The basic quality criterion of an asphalt mix is its adhesiveness; the adhesion capacity among materials. This adhesive capacity of the asphalt mix can be measured in the laboratory through qualitative or quantitative tests. The result of this analysis should be used as a reference for the improvement of the mix. In the laboratory this can be achieved using additives while at the plant it can be achieved using differing mixer technology an
