Conveyor tiles

There are many innovations with regard to conveyor tiles fitted to the flight tips. These are not only associated with the type of materials used, but also in the method by which they are secured. Many of these innovations are subject to patents [12]. 

Ceramic or tungsten carbide plates are riveted, brazed, or epoxy bonded to backing plates, which are then welded to the conveyor flight. 

The tips of the ceramics or tungsten carbide are generally chamfered to provided minimum radial contact. The mounting of the ceramic often, purposely, provides a rake to the tile.

Tile is manufactured ia several ways. la each method, a coatiauous sheet is formed gauge refinement and planishing are carried out ia subsequeat caleaderiag steps. Stresses that could lead to poor dimensional stabiHty are avoided. The efforts to preveat stresses are governed by formulatioa, stock and roU temperatures, conveyor speeds, etc. After the final calendeting, a resia—polymer—wax finish is appHed to the surface of the sheet which is thea buffed before it moves to the puach press. Frame scrap and tile rejected because of defects are returned to the mixers and recycled.

Fused basalt is utilized chiefly in the manufacture of floor tiles, castings for cyclone and other separators, nozzles, augers and grate bars the centrifugal casting technology is used in the production of conveyor pipings for mines, mill corps, etc. A special case is represented by the application of fused basalt for the incorporation of radioactive wastes. Fused rocks are dealt with in the extensive series of studies by Voldan (1955 — -1976).

Mechanical improvements include the ability to profile the protective tiles on the conveyor face, to use better bearings, and to use three-stage planetary gearboxes. Improved machine driving mechanisms include inverter drives, and the use of back-drives with power regeneration. 

A typical positive rake angle of a conveyor flight would be 1°. Sometimes this is automatically provided by the design of the tile wear protection. The reasoning behind such a raked flight is that it wilt tend to lift the cake from the bowl and in so doing reduce conveyor torque. Thus, this would not be used on soft cake/low torque applications but more on torque-producing, stiff, cohesive cakes. 

In nontire applications, there has been a faster growth in the use of synthetic rubbers such as ethylene-propylene-diene monomer (EPDM) and nitrile rubbers, as a substitute for SBR. However, nontire uses for SBR are growing with applications including conveyor belts, gaskets, floor tiles, footwear, and adhesives. 

SBR is the largest volume synthetic elastomer used by the rubber industry. Also, SBR is usually the least expensive elastomer, which may explain its very wide use, especially in the tire sector. SBR usually represents about 25% of the total monetary value of all synthetic elastomers. By tonnage, SBR now represents over one-third of synthetic rubber production however, before the introduction of radial tires in the 1960s, SBR represented 55%. Not only is SBR used in tire production, it is also used in the manufacture of conveyor belts, industrial hose, and footwear, to name a few uses. About 76% of SBR is used in tires, 15% in mechanical rubber goods, 5% in nontire automotive, and about 4% in miscellaneous applications such as shoe soles, floor tiles, and adhesives.
