Lift, convey and dewater at the same time with bucket excavators
In metallurgical industry, hot molten materials, e.g. matte or slag, can be granulated in a process, where the flow of molten material is sprayed by water causing it to disintegrate. The formed granules drop into a pit filled with cooling water.
Rotating buckets excavate material, i.e. solid granulates and liquid, from the granulation pit and performs lifting, conveying, and dewatering simultaneously for the successive process stage. From the excavator, the granules can be moved either onto a dewatering screen that further reduces the remaining water content of the granules, or they can be directly fed into a silo by a box-type belt conveyor.
Perfected over the years
We applied our experience from the existing delivered granular bucket excavator projects and developed the latest excavator to meet the highest requirements in terms of wear and chemical corrosion resistance for the best availability and performance.
Kopar bucket excavators are an excellent choice to fulfill all the needs and requirements in mining, comminution, material handling and liquid/solid separation. Built to last, they can withstand the continuous stress of lifting and conveying heavy materials.
Bucket excavators include all the necessary bucket-ladder elements so that the excavated material can be transferred directly to the conveyor. In every excavator design we aim to meet the specific demands and requirements of the project in terms of optimization, standardization, and maintenance. We can offer water screens, belt conveyors and silos from our portfolio to complement and unlock the full potential the bucket excavators.
