Inquiry (采购产品): Rotary dryers required Gentlemen: We are a firm of manufacturers' agents specializing in filtration, separation and drying equipment for the major process industries. We currently have two customers who are in the market for direct-fired rotary dryers. One of our customers requires an economical way of partially drying 6 to 7 tonnes per hour of paper sludge having a moisture content of 50%. The sludge is being dewatered by screw presses and the customer is currently installing incineration equipment to burn the sludge. Reduction of moisture content should permit autogenous combustion, thereby dramatically reducing, if not entirely eliminating, the need for cofiring with natural gas. 71000 cubic meters/hr of exhaust gases at 170 deg Celsius are available for the drying process. We would appreciate your guidance on the moisture content reduction that can be achieved with a direct-fired rotary dryer, simply by employing these exhaust gases. (We recognize that temperature and volume of these exhaust gases will likely be insufficient to achieve much evaporation, but even a 10% reduction might be acceptable.) We would like to know what size of dryer would be required to most effectively utilize the heat in the exhaust gas stream. This customer will consider purchasing and refurbishing an existing dryer to save time and costs. Another customer wishes to dry sawdust and other wood waste, moisture content of which varies between 40 and 50%. They require the moisture content of this material to be reduced to the 5-10% range for further processing. We understand that exhaust gases are available from other processes, but need to establish volumes and temperatures. This customer will likely elect to purchase a new rotary dryer for this application, but would also be open to a reconditioned used dryer. In addition to these two customers we have other prospects in the major process industries who will be requiring direct-fired rotary dryers in the coming months. Since we do not currently offer a line of rotary dryers we are interested in the feasibility of establishing a continuing relationship with a company such as yours that is actively manufacturing, installing and maintaining such equipment.
