Due to the long-term exploitation of river sand, the remaining river sand resources are very limited. For machine-made sand, its raw material stone resources are very abundant. Granite and limestone can be used to produce stones. Therefore, stone sand naturally stands out. What is the difference between these two common granite and limestone? This article will give you a detailed understanding of what equipment is used to produce stones.
1. The difference between granite and limestone.
01. Different hardness:The hardness of granite is about 8, which can be scribed on the surface of basalt and limestone; The hardness of limestone is 2 to 3. It is soft and can be carved by granite and limestone.
02. Different appearance:Granite has granular crystals, black spots, colorless and translucent adaptation and flesh colored feldspar; The limestone surface has different shades of color formed by biological remains.
03. Different uses:Basalt stone is an excellent material in the stones used for roads, railways and airport runways. It has the advantages of strong compression resistance, low crushing value, strong corrosion resistance and asphalt adhesion. At the same time, it can also act as a lubricant in a cast steel process; The amount of limestone is relatively large among all ores. In the process of ironmaking, steelmaking, metallurgy, glass manufacturing and cement clinker, there should be limestone containing more than 85% of calcium carbonate, with the amount of more than 20-25%. At the same time, it is also an important and commonly used reducing agent. Some people say it is the mother of chemical raw materials!

2. How to configure a full set of stone production line equipment?
01. Equipment required for granite stone production line.
A complete granite stone production line has processes such as feeding, crushing, sand making, screening, sand washing and transportation. The equipment involved is composed of jaw crusher, cone crusher, granite sand making machine, circular vibrating screen, belt conveyor, vibrating feeder and other equipment. These equipment can be matched and combined according to the requirements of sand making production process.
A. Coarse crushing: jaw crusher is responsible for the initial crushing of granite. The feed is less than 1200mm, the feed inlet is large and the crushing ratio is large;
B. Secondary crushing: conical crusher is used for the secondary crushing of granite stones. It adopts lamination method, with strong crushing strength. The wear-resistant parts are made of high wear-resistant materials, with feeding less than 560mm and discharging up to about 5mm;
C. Sand making: granite sand making machine is responsible for sand making and shaping the crushed granite stones. The discharge particle size and type of finished sand can be adjusted according to the production needs of users . The particle shape is good, the uniformity is high and the grading is reasonable;
D. Sand washing: the sand washing machine is responsible for cleaning the finished machine-made sand after sand making processing, cleaning out sand, dust and other impurities, and improving the quality of finished sand.
02. Equipment required for Limestone production line.
Due to the hardness of raw materials, the equipment of limestone production line can be matched in many ways, and the effect is good.
A. Feeding + jaw crusher + impact crusher + vibrating screen + conveyor belt.
The standard stone production line configuration scheme uses jaw crusher for coarse crushing, large feed inlet and high output. It uses impact crusher for fine crushing, which has certain shaping function and long replacement cycle of worn parts, which can also meet the needs of users.
B. Feeding + hammer crusher + vibrating screen + conveyor belt.
Broken limestone can be formed at one time, with high particle shape uniformity and good effect, reducing the investment cost by more than 40%.
The above stone production line scheme can be adjusted according to different needs of users, such as output, site, particle size, etc. if you have needs, you can consult online at any time. We tailor it for you and look forward to cooperating with you!
