Megaton crushes and sorts aggregates for concrete, asphalt and general construction purposes

E-Mak’s latest invention is an aggregate factory which takes rock from a quarry, crushes it, sorts the aggregates into sizes and delivers them in the proportions required. Called Megaton, it can be used for aggregate production, concrete production, cold mix production and aggregate production.

Megaton has been designed to operate in major materials production facilities, close to large conurbations. It can be built to serve all or any combination of the applications mentioned above.

“The inspiration actually came from Istanbul, where there is a huge quarry, used by multiple construction companies, which is now surrounded by houses due to the increasing population of the city. In situations like that Megaton would be ideal,” said Onur Recepgil, brand and marketing manager for E-Mak.

As well as limiting dust, Megaton prevents aggregates from taking on moisture, reducing the energy needed for asphalt production. Due to the controlled environment in which the aggregates are stored, it can also lead to higher-quality materials, according to E-Mak.

The first version of the Megaton will be erected at a quarry and materials production facility in Bursa, Turkey, which is owned by E-Mak sister company Singemat, having made a show-stopping appearance at Bauma 2019 in Munich.

The Megaton process sees pieces of rock from a quarry fed through a vertical shaft impactor (VSI) crusher with a capacity of 450tonnes per hour. The aggregate is then lifted by a vertical elevator into the sieving units for grading and is then stored according to its size within the 3,000tonne-capacity silo. The right combination of aggregate grades can then be delivered directly to an aggregate or concrete plant.

“At the quarry in Bursa we will have two sieving units, one to serve concrete production and the other for asphalt production because they require different gradings,” explained E-Mak international sales manager Muhammed Elhatip.

As well as benefits to air quality and energy savings due to having dry aggregates, the Megaton could also make production more efficient, said Elhatip. “The machine could run all night, for example, so that you have 3,000tonnes of clean aggregate ready for production in the morning.”
