According to statistics, nearly two years of sand and gravel annual estimates of up to 100 tons, the annual output value of 300000000000 yuan, driven by the transportation industry output value of 535000000000 yuan, the total output value of 235000000000 yuan, the first in the world, the first in the world. China mechanism sand and gravel industry is in the morning sun.
Stone crushing production advantages not available in other industries -- relying on the mine resources, sales radius general in less than 100 km, the ex factory price average about 25-20 yuan / ton, payment soon. Therefore, under the huge market demand, the stone crushing production has the very high profit space.
The main chemical composition of the material is the silica, which is a kind of ideal green building material. But because of the stone itself hardness is bigger, so when broken or sand on the stone by which pebbles play sand making machine good?
The traditional selection scheme of the "e + cone breaking + impact break" is used to make sand, although the impact type sand making machine has a large processing capacity, but the sand production efficiency is low, the sand production efficiency is only 20-30%, so the output of the two sand making machine is 90-100t/h.
In addition, Symons cone crusher PYS1300, sand efficiency is very low, adjusted to the best state can only reach about 20%, out sand content in the 50t/h, so whole pebbles and sand production line of sand content barely reached its 150t / h.
And if the "Hubei broken + German sand making machine, the R1200 types of German sand making machine into material, can reach 80-100 mm, sand efficiency is very high, yield at least reached about 100t / h, only need in the jaw breaking configuration screen to form a closed circuit can realize two-stage crushing of sand.
Moreover, the sand production rate is more than twice that of the impact type sand making machine, not only greatly simplifies the production process, but the actual output of the whole sand production line can reach 160t/h or more, can meet the requirements of production.
Therefore, stone crushing production not only high profit and if the pebbles, sand blasting machine can greatly improve the pebbles and sand production line production capacity, while reducing the stone crushing cost of production line, so that the sand making machine, Germany is a rare cobblestone play sand machine.
