In order to reduce the wear on the surface of the plant components, which are submitted to considerable mechanical and chemical degradation at high temperatures, we recommend that our clients use MARINI ENDURANCE special anti-wear sheet-plating. The result is longer lasting plants, with consequent reductions in the costs of maintenance and repairs.
We know that wear is a phenomenon which results in damage to the surface of two solid bodies which are in contact and in relative motion. There are various kinds of mechanisms involved in this phenomenology, but the one which effects the production of our plants most is one of the quickest and severest forms of wear and tear – abrasion.
By abrasion we mean the damage caused to a plate by the passage of particles of a material which are as hard as / harder than the plate surface itself, and this can have several results, each with its own characteristics.
MARINI ENDURANCE consists of carbon sheet plates soldered with a high-density chromium carbide alloy lining, which increases resistance to abrasion, even at high temperatures, without effecting the flow of materials and the costs.
(e.g. basalt materials)
especially when the exact nature and shape of the material is not known and which could be highly abrasive. In order to encourage the flow of the material, the chutes are usually heated, and it is known that high temperatures can have a negative effect on the hardness of the material. For this reason if RAP is used in the recycling ring, MARINI fits out the plant with a complete kit of resistances to heat the discharge chutes, together with MARINI ENDURANCE plates.
The plates have holes for quick and easy assembly and replacement with bolts. It is therefore possible to purchase the kit right at the beginning of the plant’s life, or it can be installed at a later date during retrofitting procedures.
