With the support of sand-making technology, machine-made sand has the advantages of being superior in quality and gradation, so it has developed rapidly in recent years and attracted the attention of a large number of investors. Quartz stone was commonly used as decorative material before, with average texture and properties. Can quartz stone be used to produce machine-made sand? What is sand-making process of quartz stone?
一：.Can quartz stone be used to produce machine-made sand?
Machine-made sand is generally made of rock, mine tailings or industrial waste residue particles by mechanical crushing, screening and soil removal. It is commonly known as artificial sand, which is divided into different grades according to quality and gradation. As a stone with Mons’ hardness of 7-8, quartz stone is characterized by strong pressure resistance, no toxicity and no radiation.
Quartz stone can be made into manufactured sand after proper processing, and the finished product is featured with good particle shape and strong controllability of particle size. Market statistics show that there are quite a lot of users who choose quartz stone for production of manufactured sand and the price of the finished product is almost above the average price, with considerable profit. In addition to concrete and mortar, manufactured sand made of quartz stone can also be widely used in glass, casting, ceramics, refractories and other sectors, with a broad market and high demand.
二：. Detailed Explanation on Sand-making Process of Quartz Stone
1. Feeding + coarse crushing
The equipment used in this link are mainly the vibrating feeder and jaw crusher. Quartz stone is transported from the feed bin or excavator to the vibrating feeder and then uniformly transported to the jaw crusher for coarse crushing after simple screening.
2.Screening + secondary crushing
The facilities equipped in this link are the vibrating screen and cone crusher. The quartz stone processed in coarse crushing is transported to the vibrating screen by the conveyor. The vibrating screen removes quartz stones not meeting the feed size required by the cone crusher, and returns them to the jaw crusher to crush again; the quartz stones meeting the requirements can enter the cone crusher for secondary crushing.
3. Sand making + sand washing
The devices equipped in this link are the sand maker and sand washer. After the above-mentioned coarse crushing and secondary crushing, quartz stone is made into a stone with a diameter less than 5 cm and then into sands of different specifications after continuous impact and crushing by sand maker. After re-screening, the sand washer is used for the cleaning work and removing impurities such as soil and stone powder on the machine surface.
Quartz sand making equipment has the advantages of large crushing force, good wear resistance, stable operation, simple structure and easy maintenance, etc. The sand produced is of excellent quality and widely used in the construction industry.
