A Limestone quarry in Poland contained a seam of material, heavily contaminated with sticky clay and had been unable to process this previously and needed a new solution.
This material was causing issues in their crushing train by continuously clogging the crusher pre-screen. Forcing clay into the crushing chamber, slowing production and causing unnecessary wear on the crushing components.
The clay-bound material was proving so difficult to process that the customer resorted to stockpiling it in another area of the quarry. This practice was wasting valuable time and resources, as well as adding unnecessary costs.

The MDS M515 heavy duty trommel offers a different screening mechanism compared to other traditional screeners. The rotating drum promotes tumbling of the material. This, coupled with a longer retention time results in a scrubbing action and helps to break loose the clay and other impurities. This unit was also fitted with a drum cleaner mechanism designed to keep the drum openings clear even in the harshest conditions.

1. Clay Separation: The M515 effectively broke up clay from rocks, creating a broken up minus 75mm (3”) fines product that could be further processed.
2.Space Optimization: By processing this material, the customer significantly reduced the amount of unusable material stockpiled, creating more room in the quarry, and enabling more efficient operations.
3.Product Diversification: The machine created 4 different sized products:
The implementation of the MDS M515 heavy duty trommel revolutionized the processing of previously unusable sticky limestone. By effectively breaking down clay content and producing various sized products, the machine not only optimized quarry space but also contributed to environmental sustainability.
