Matrox® reduces the Highly qualified employees, superior material load on the structure and makes development, state-of-the-art production installation work much simpler. facilities, laboratories and a certificated quality management system are the basis for the high quality and economic efficiency of the products. Our excellent reputation among the world’s leading flow consultants and engineering experts in the field of bulk solids flow has been achieved by earning Material Specific gravity Weight for respect based on providing the industry with thickness thickness g/cm³ 200 m² [kg] unmatched consistent, reliable solutions to Steel 3 mm 7.85 4,710 flow problems. Matrox® 10 mm 0.93 1,860 Matrox® Weight reduction with Matrox®: 2,850 kg ~ 60 % The new formulation of Matrox® has specifically been developed for the bulk material handling and mining industry to reduce the typical flow problems of bulk solids in bins, hoppers, chutes, truck beds and other applications. However, every application makes its own special demands on the lining material. In order to meet these, Röchling Engineering Plastics has cooperated closely with specialists and users in modifying tried and tested plastic materials for widely varying fields of use. The products of the Matrox® range combine the best surface friction qualities with abrasion resistance not only to promote bulk material flow but also to withstand the abrasion resistance of flowing bulk materials in rugged applications under different environmental conditions. 42 | Röchling Industrial ® Matrox®Matrox crée l’avantage Relative volumetric wear according Typical applications to the sand-slurry process The products of the Matrox® range are used in a wide variety of In the sand-slurry test, a mixture of sand and water is used to test the industries that handle bulk materials from the mining level up to resistance to abrasion of a test sample compared to a defined reference and including the final processing or use of the product. Changes in material of PE-UHMW with a molecular weight of 5 million g/mol to moisture and particle size affect the product’s flowability. Traditional which a fixed value of 100 is assigned. The volume lost by the test steel surfaces become rough or corroded causing the bulk material sample during the test is then stated as an index compared with that to stick to the steel. The problems deteriorate and productivity and of the reference material. The lower the value achieved, the better the quality control are compro mised. resistance to abrasion.
