“Energy conservation and environmental protection” has long become a hot topic. Energy conservation, emission reduction and green environmental protection have become unavoidable priorities for every industry, and the river sand dryer equipment industry is no exception. Chinese mining equipment enterprises have launched a slew of products incorporating concepts such as “technological innovation”, “environmental protection” and “remanufacturing”, which means that as the entire industry transitions toward green and intelligent development, the concepts of energy conservation, emission reduction and green environmental protection have permeated every aspect of its development.
Driven by national policies, the river sand dryer equipment industry is advancing steadily, the overall pattern of the mining equipment industry is constantly adjusting, and major enterprises are increasing investment in talent training and technological innovation. The mining equipment industry advocates the rational matching of engines with transmission systems, working systems and traveling systems, which can achieve excellent energy-saving effects. At present, enterprises are focused on researching the optimal type of engine for different types of mining equipment to ensure that their power curves deliver optimal energy-saving performance. Today, we will detail the common problems encountered during the operation of river sand dryers.
After drying materials, river sand dryers leave a certain amount of moisture in the materials, which then clump together and cause blockages at the discharge port! This issue can be identified by two key signs: a sudden surge in the pressure of the high-pressure pump, and a noticeable rise in the temperature at the tower outlet. In cases of partial blockage or incomplete drying in the river sand dryer, the change in high-pressure pump pressure is not obvious, but the temperature of the gas at the dryer’s outlet will rise significantly. Immediate intervention is required in all such scenarios; otherwise, a large amount of waste will be generated, and even other equipment malfunctions may be triggered.
In such situations, the blocked materials at the discharge port must be cleared promptly, and we must prioritize resolving the immediate issue! A pneumatic pressure system or a combined river sand dryer can be used for this purpose. This type of dryer integrates the dual functions of a pneumatic river sand dryer and a pressure river sand dryer: when starting up the equipment, compressed air is used for drying until the high-pressure pump reaches the required drying pressure, at which point the compressed air supply is stopped. Similarly, if the river sand dryer malfunctions and fails to dry materials properly for any reason, this method can also be adopted to prevent the production of wet materials—and it is a highly effective solution to this fault.
