The crushers play a vital role in the production of sand and gravel. It has various types and wide utilization.
From the working principle, crushers are primarily categorized into extrusion types and impact types. The extrusion-type crushers, which include jaw crusher, gyratory crusher, and cone crusher, suitable for processing materials with high hardness and strong abrasiveness, such as iron ore, granite, and other metal ores and hard rocks. These crushers ensure production efficiency and finished product quality by utilizing powerful compression forces to break down materials. Impact crushers, including vertical shaft impact crushers and hammer crushers, are particularly effective for crushing medium to low hardness and abrasiveness rocks such as limestone and dolomite. By utilizing the impact force, these crushers can produce materials with regular shapes and well-graded sizes.
Coarse crushing link: jaw crusher or rotary crusher is often used. The jaw crusher is widely used. Its simple operation makes it ideal for small and medium-sized production lines, capable of producing up to 1000 tons per hour. The gyratory crusher boasts an impressive processing capacity, with a single production output exceeding 2000 tons per hour, making it perfect for large-scale sand and stone production. It can provide suitable coarse materials for subsequent processing steps. Additionally, for some medium to low hardness materials, a large-size impact crusher can be utilized. This type of crusher offers a high crushing ratio and low energy consumption.
Medium and fine crushing stage: the cone crusher is ideal for processing high-hardness rocks. It utilizes the movement of mental against the concave to compress materials, ensuring high production efficiency and excellent stability. Meanwhile, the impact crusher has a good crushing effect on rocks below medium hardness, excels in breaking medium-hardness rocks or lower, producing beautifully shaped particles, reduce the need for additional shaping work and meet various product requirements.
Sand making process: vertical shaft impact crusher is a popular choice for sand making, which emulates the natural process of sand formation. The finished sand is rounded and well-graded, meeting the standards for top-tier construction sand, and can also be used to shape stones. The rod mill is suitable for special projects with high requirements for the roundness and grading of sand; The rolling machine is often used in small production lines or occasions where the particle size of the finished product is strict, and can produce uniform fine materials to meet diversified market demand, and aids in efficiently generating high-quality sand and stone aggregate for sand and stone production lines.
