Sand Making Machine Production Process
At present, there are three main forms of domestic sand production. One is to produce mineral sand while specializing in the production of minerals. This is mostly for large enterprises (that is, an annual output of more than 1 million tons of sandstone), with good quality and several hundred; One is to use the pebbles to produce mechanical sand in the river, or to mix the sand with a small amount of natural sand. This is mostly a medium-sized enterprise (that is, an annual output of about 500,000 tons of sandstone). The quality is good and the difference is large, the difference is large. Also in a few hundred or so: another is the use of a variety of tailings production, mainly in the production of limestone gravel after the stone chips or stone powder, after simple
Chat Online >There are two core equipments for high-quality mechanical sand production lines: one is sand making machine ; the other is sand washing machine or dust collector and sand stone powder separator.
The production of machine-made sand can be mainly divided into two processes: wet process and dry process. The role of the sand making machine is to further break up the large particle crushed stone into rock particles with a particle size of less than 4175 mm.
The performance of the old sand making machine is not good, the mechanism of the production sand is not good, the corners are too much, the needles are too much, and the prepared concrete has poor workability, which hinders the application of the mechanism sand in pumping concrete.
Most of the modern new sand making machines have the shaping function, and the mechanism sand produced is spherical, which is close to natural sand, which is beneficial to the application in pumping concrete. The role of the sand washer or dust collector and the sand and stone separator is to remove mud and stone powder from the machine sand.
The wet production process removes the mud and stone powder from the mechanism sand by washing with a sand washing machine; while the dry production process removes the mud and stone powder from the mechanism sand by means of a dust collector and a sand and stone separator.
The traditional process is mainly wet: but because the wet process is limited by the water source, its promotion is limited, and the dry process is becoming more mature due to its dust collection process.
