In recent years, the amount of sand and gravel used in construction has been increasing, and natural sand and gravel mining is facing the pressure of resource reduction and ecological environmental protection.Under the premise of improving the awareness of ecological environmental protection for resource protection and pollution reduction, the use of ore, tailings and river pebbles to produce artificial sand has been widely used.Sand and gravel are one of the essential raw materials for construction, so what are the stones used in construction?This article will introduce and recommend stone processing equipment for construction in detail for you.
What are the stones used in construction?
Most ordinary mountain stones and rocks can be processed into construction stones. Limestone and granite are commonly used in construction sites. In addition, there are andesite, gabbro, basalt, gneiss, marble, quartzite, limestone, dolomite, etc. These rocks have different hardness and different physical properties. After processing according to the standards of construction stones, they can be used in different engineering projects.
| According to their respective physical properties and mechanical hardness, they can be roughly divided into: | |
| Hardness | Rock |
| Extra hard rock | Basalt, diabase |
| Hard rock | Granite, quartz porphyry |
| Medium hard rock | Quartz stone, pebbles, river pebbles |
| Softer rocks | Limestone, gypsum |
Recommended stone processing equipment for construction
Some of the above-mentioned construction stones can be used directly, but most of them still have to be processed before they can be used. The rocks are processed into sand and gravel aggregates by crushing equipment and screening equipment, which can be used in construction, highway and other industries.So what are the equipment for the production of building stones?The following is Xiaobian’s recommendation:
1, Jaw crusher: The feed particle size is below 1200mm, and the production capacity is 1-1100 tons per hour. It is a very common crushing equipment. It is used in the first process of crushing various ore rocks. It can process various ores with compressive strength not higher than 320MPa to medium particle size at once. It is often used with cone crushers, impact crushers, sand making machines, etc. Together to form a complete set of sand and gravel production lines, which can handle a variety of rocks and are necessary equipment for the production of building stones.
2, Cone crusher: The feed is below 560mm, and the production capacity is 27-1050 tons per hour. It adopts the principle of laminated crushing and integrates mechanical, hydraulic, electrical, automation and intelligent control technologies. It can be widely used in medium, fine and ultra-fine crushing operations in metal and non-metallic minerals, cement, sand and gravel, metallurgy and other industries.
3, Impact crusher: The particle size of the feed is below 1300mm, and the production capacity is 250-2000 tons per hour. It adopts the principle of impact crushing. The machine has strong rigidity and the rotor has a large moment of inertia. The advantage is that the finished product has a better particle shape and the material is not easy to clog. It is suitable for crushing medium-hardness rocks with compressive strength below 350Mpa.
4, Sand making machine: The feed is below 50mm, and the production capacity is 109-486 tons per hour. In view of the increased demand for large-scale, intensive, energy-saving and environmental protection in the sand and gravel market, as well as high-quality machine sand, a new four-port impeller design structure and a special sealing structure are adopted to prevent oil leakage from the bearing cylinder and other processes. The new sand-making and crushing equipment with a number of national patented technologies has the characteristics of energy saving, long service life, and wide application. It helps large sand farms gradually move towards large-scale and centralized production to meet the country’s environmental protection and production capacity requirements. request.
