At present, various stones are crushed to make sand through artificial sand making production lines to obtain sand with different particle size specifications. The grain shape is excellent and the texture is uniform. The so-called machine-made sand can effectively replace natural sand. It can be used as a highway and high-speed railway, high-rise buildings, municipal administration, hydropower dam construction, concrete mixing plants and other raw materials. So, how can we know what stone is suitable as raw material for an efficient and environmentally friendly machine-made sand production line? What kind of crushing equipment should be used accordingly?
1. Choose the right stone according to local conditions
According to statistics, there are currently more than 200 kinds of ore materials in the mining industry that can be used to produce machine-made sand, including common pebbles, river pebbles, bluestone, and granite. Regarding which raw material is better for machine-made sand, cobblestone and river pebbles account for a higher proportion. Other granite, limestone, bluestone, quartz stone, waste concrete, construction waste, etc. can be used for sand making, but it should be noted that stone. There are high and low hardness, the corresponding crusher equipment configuration is also different, the most common are the following two configuration methods.
First, for hard rock, which has higher hardness and abrasiveness index, choose "jaw crusher + cone crusher + sand making machine".
Second, for limestone with moderate hardness and abrasiveness index, choose "jaw crusher + impact crusher" or "impact crusher + impact crusher".
2. Make it according to the material and choose the right equipment
The quality of sand is not only related to raw materials, but also related to the purchase of sand making equipment. Therefore, it is necessary to choose a suitable sand making machine for different material characteristics. In order to obtain high-quality machine-made sand, it is necessary to choose high-quality processing equipment with high-standard and advanced sand processing technology. If the configuration is not appropriate, the crushing equipment does not meet the requirements, it will inevitably cause serious impact on the stone. So how to choose equipment? Compared with the traditional sand making plant, the current one-stop sand making production line configuration is more suitable and has the following characteristics and advantages:
1. High degree of automation and equipped with new technology dust removal equipment to reduce dust and meet the requirements of environmentally friendly equipment.
2. High production efficiency, low operating cost, large output and high profit. The finished stone has uniform particle size and good shape, which meets the material requirements of the construction industry.
3. The equipment configuration of the sand production line is mainly based on the customer's output and use requirements, and the customer's production site is inspected to design the production line, so that the designed production line is reasonable, economical and efficient.
4. The sand-making production line adopts a cross-space layout, which has the characteristics of small area and high investment and economic benefits. At the same time, it is equipped with an electronic control operating system, which makes the whole process unblocked, reliable in operation, convenient in operation, and highly efficient and energy-saving.
