What are the uses of granite after it is broken into sand?

Most people’s cognition about granite still stays in building materials, but in fact, granite stones and sand have passed professional testing and have been proved to be applicable in various engineering fields, especially some large-scale construction projects will also be specially designed Buy granite stones and sand to equip high-strength concrete; the detailed usage is as follows.

1. 13 stones with a particle size of 16-31.5mm are often used for irrigation of large-scale high-rise foundations and road foundations, and have the characteristics of high strength and strong adaptability;

2. 12 stones with a particle size of 10-20mm are more suitable for small-scale concrete equipment, with better slump and higher fluidity;

3. Although the 51 crushed stone with a particle size of 5-10mm is also commonly used to equip concrete, its particle size is small, and its role is to reduce porosity and save cementitious materials.

Due to the large particle size of the granite raw material, multi-stage crushing is used, the product particle size is finer, the particle shape is good, and the quality is higher, which meets the requirements of high-quality construction sand and construction stones. The scraps generated during the processing process can realize resource reuse. , reduce over-exploitation and alleviate the tension of sand and gravel supply. A major way to realize the comprehensive utilization of granite is to crush it reasonably, and then it can be widely used in construction, bridge arch, pavement, foundation stone, chemical industry, metallurgy and other fields. It is an investment project with development prospects.

Encyclopedia of granite crushing equipment, production line configuration

The process of granite sand making is generally crushing, screening, sand making, sand washing, etc., which requires crushing equipment, feeding equipment, conveying equipment, sand making equipment, sand washing equipment, etc.

Crushing equipment is the central equipment in the granite processing process. Screening equipment, feeding equipment and conveying equipment are indispensable auxiliary production equipment in the production process. The cooperation of these equipments can achieve very good production results. The jaw crusher has high crushing strength and large crushing ratio, and the jaw crusher and cone crusher have very few wearing parts, which can effectively reduce the wear of parts during the production process, reduce the equipment failure rate, and improve production efficiency.

1. Coarse crushing: The texture of granite is relatively hard, and it is not efficient to directly use it for sand making, and it will cause great damage to the sand making equipment, so it should be crushed first. The initial crushing by the jaw crusher can make all kinds of massive granite with uniform particle size, which meets the requirements of the feed port of the sand making machine, with large output, large crushing ratio, uniform product particle size, low equipment price and low investment. The cost is small.

2. Medium and fine crushing: the cone crusher is selected, the new crusher structure, and the optimized laminated crushing cavity make the production capacity large and the crushing efficiency high. In addition, it also has the characteristics of automation and intelligence, high production safety and good environmental performance. It is suitable for customers with hard materials and high output requirements, but not high requirements on grain shape.

3. Fine crushing: sand making machines, HVI sand making machines and VSI sand making machines can be used, with high throughput, long service life, wide adaptability, and the finished product has good grain shape and uniform size, which can be used for construction, water conservancy and other industries. Provide high-quality sand and gravel aggregates. It can effectively reduce the amount of sand making dust and create a green sand making environment for users. In addition to crushing, the sand making machine has a shaping effect, and the finished product is of high quality, which is a high-quality sand and gravel that meets the national standard.

4. Sand washing: use wheel bucket sand washing machine, which has large output, low equipment price, energy saving, and water can be recycled.

The vibrating feeder transports the granite to the jaw crusher for coarse crushing, and then transports the granite to the cone crusher for secondary crushing by the conveyor. The small ones enter the sand making machine for shaping and sand making, and the larger ones enter the jaw crusher or cone crusher for secondary crushing, and cycle back and forth to obtain finished sand and gravel products of different specifications and particle sizes.

Under normal circumstances, the company will assign professional technicians to the user’s production site. After investigating the production site’s terrain and production environment, combined with the user’s production needs, the company will equip the user with a suitable granite crushing production line.

(1) The internal structure planning of keyless connection is adopted to reduce the difficulty of equipment maintenance and ensure that the equipment runs more smoothly, more economically and reliably;

(2) The optimized planning of the feed port and the crushing chamber is more suitable for the crushing and processing of high-hardness and large-size granite stones, and the content of stone powder in the product is less;

(3) The blow bar is made of a new type of high-chromium material, which has strong impact resistance and wear resistance, which greatly improves the crushing efficiency and prolongs the life of the equipment itself by 2.5 times.
