The DustPro Spray System uses a high pressure 200 psi pump capable of reducing dust to compliant levels, and is electronically-controlled from a remote panel in ...
reduce particle sizes. In rock crushing operations, rock is loosened by drilling and blasting and then loaded by front-end loader or power shovel into large haul trucks that transport the material to the processingoperations. Processing operations may include: crushing, screening, size classification, material handling and storage operations.
· The crushing and screening line is designed with double production lines, and the single-line production capacity can reach more than 800 tons per hour. The advantage of the double production line over the single production line is that the production capacity is guaranteed and the production cost is relatively low.
air classification. At some plants, after initial crushing and screening, a portion of the sand may be diverted to construction sand use. After initial crushing and screening, industrial sand and gravel are washed to remove unwanted dust and debris and are then screened and classified again. The sand (now containing 25 to 30 percent
The environmental pollution caused by sand and gravel production lines is mainly dust, noise, and sewage generated during the production process.. Dust mainly comes from the discharge points of crushing and screening equipment, transportation, and transfer points, finished aggregate storage and unloading points, and dust
