Granite is mainly composed of feldspar, quartz and mica, which belongs to a kind of ore with hard and dense rock. Therefore, it is more difficult to break up than some soft rocks such as limestone. However, although granite is hard, it is a building decoration material with beautiful texture. In addition, it is also widely used in expressway, high-speed railway, buildings, bridges and tunnels and other infrastructure construction, so it has become a direction with good investment prospects.
For the granite crushing production line with an hourly output of more than 250 tons, a complete crushing production line generally needs to be composed of a vibrating feeder, a PE series jaw crusher, a HPT series hydraulic cone crusher, a VSI series sand making machine, a circular vibrating screen and an iron separator.
In the crushing process, the primary crusher shall be selected first. The common primary crusher are PE jaw crusher and PEW European jaw crusher. These two types of primary crusher are low in cost, simple in principle and stable in performance. PE jaw crusher is a more appropriate equipment and needs to be equipped with a vibrating feeder.
The second is two-stage crushing, which generally requires cone crusher or impact crusher. When the material is crushed to a certain fineness, it can be transported to the sand machine for fine crushing and shaping.
In addition to the startup, shutdown and daily maintenance of the equipment, the whole production line hardly requires manual operation. The stone production line has high automation, high production efficiency, low operation cost, high output, and even particle size of the finished stone, which can fully meet the actual production needs of different customers.
SMMVIK Machinery has many years of production experience in the mining crushing machinery and equipment production industry. The various mining crushing production lines, gravel crushing production lines, gravel sand production lines, grinding production lines and production plans configured for customers are all over the country and abroad.
Our engineers generally make reasonable equipment configuration according to the customer's actual production situation, site, material application field, finished product output and other conditions. In the design of the process flow of the crushing and screening combined equipment, each crushing equipment is reasonably matched, and strict spatial cross layout is considered. It has the characteristics of small floor area, high investment and economic benefits, good quality of crushed stone, and low output rate of stone powder. It is highly praised by customers.
