In Sweden a company manufacturing wall plaster used ALLU screener crusher to crush defective wall plasters. During years the pile of defective material had grown to several tonnes.

ALLU screener crusher replaces expensive crusher that would propably not have had any additional use after the pile had been crushed. 

The screener crusher crushed a "mountain" of defective wall plaster and after that the company has used the unit to crush other waste materials that have accumulated at the factory and made a lot of savings in waste handling costs.
