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 Challenge:

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 M515 Heavy Duty Trommel Solution:

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.
