Mine crushing
Production Line Introduction:The mining crushing line, also known as the crushing production line, is a specialized equipment combination for producing construction sand and metallurgical and chemical stone materials. It is mainly used for processing rocks such as limestone, basalt, and granite. The main equipment includes a vibrating feeder, jaw crusher, impact crusher, cone crusher, vibrating screen, and conveyor belt. The stone materials are evenly fed into the jaw crusher for primary crushing by the vibrating feeder, then finely crushed by the impact crusher or cone crusher, and finally screened by the vibrating screen to separate stones or sand particles of different specifications.
Production Capacity:50 tons~3000 tons/hour
Production Raw Materials:Limestone, granite, basalt.
Product Types:Stone materials 26-31.5, 15-26, 10-15, 5-10, 0-5, mechanically produced sand 3.5-6, 0-3.5
Highlight Advantages
(1) High degree of automation, simple operation, and low personnel input.
(2) Good product quality, uniform particle size, and low dust content.
(3) High yield and low consumption, excellent equipment performance, fast production speed, and low energy consumption.
(4) Wide range of applications, can process materials of different hardness and moisture content.
(5) Mining crushing lines are widely used in mining, construction, and highway fields due to their high efficiency, energy saving, and environmental protection characteristics.
Process Flow
The crushing production line adopts a multi-stage crushing method, which can crush the limestone raw materials with a larger original particle size into finished materials with a finer fineness. Large blocks of materials are first roughly crushed by two heavy-duty hammer impact crushers. After screening, part of the finished materials is obtained. The large blocks of materials screened out are returned to the shaping hammer crusher for fine crushing and shaping. The materials after secondary crushing are screened again by a vibrating screen to obtain finished materials of different particle sizes. Each link and each dust removal port are equipped with a mining dust collector for dust collection at the source to ensure green production. The crushed materials have reasonable product grade matching. The qualified rate of the finished materials produced is over 90%, ensuring product quality. A multi-level conveying screen transports the crushed finished materials to the corresponding processing bins, and the capacity can reach the design output.
(1)Feeding: The raw materials are continuously and evenly sent to the primary crushing equipment by a feeder (such as a vibrating feeder).
(2)Coarse Crushing: Mainly relies on jaw crushers, whose powerful crushing force is suitable for ores of various hardnesses, making it the preferred choice for coarse crushing.
(3)Medium and Fine Crushing: The crusher is selected flexibly according to the ore hardness. For soft ores, impact crushers are preferred; for medium-hard and harder ores, cone crushers are selected.
(4)Screening: The crushed sand and gravel materials need to be graded through screening operations. The vibrating screen integrates screening and feeding functions, and can effectively control the specification of finished sand and gravel materials.
(5)Conveying: Belt conveyors are mainly used to transport materials and connect various equipment, ensuring the orderly operation of each equipment. Stones that do not meet the particle size requirements will be returned to the crusher for re-crushing.
This process flow design needs to reasonably configure equipment according to the working site of the production line, material characteristics, and output requirements to save energy and reduce time.
