Agglomeration belt conveyor

Another simple agglomeration method is belt conveyor agglomeration (Figure 365). It is really a modified stockpile agglomeration system with additional sprays and mixing at each transfer point from one conveyor to the other. The number of transfer points depends on the amount of fines in the ore that must be bonded onto larger particles or agglomerates. 

The same principle of agglomeration can be applied at multiple transfer points from belts to belts, on shaking or vibrating conveyor decks, or on steeply inclined belt conveyors where material tumbles downward against the upward motion of the belt [B.48, B.97] (Section 8.1, Figs. 8.14, 8.15, and 8.16). 

The use of TDF is, unfortunately, not without concerns. In most instances, the steel wires within the tire chip cause problems with large-scale fuel handling equipment. These wires intertwine and form large agglomerates that plug handling equipment and even tear conveyor belts. The steel wire within a tire chip may also be a concern in the combustion of the TDF as the additional iron may result in increa in corrosion rates and slagging on boiler waterwalls. Other constituents in the ash such as zinc or chromium may also be detrimental to overall boiler efficiency.
