Quartz watch is one kind of wrist-watches, making the quartz crystal used in the clock is a modern invention. The first quartz watch appeared in 1969.The vibration frequency of quartz crystal per second up to 32768 times, we can design simple electric circuit to calculate the number of its vibration, when it counts to 32768, the circuit will spread the message and let the second hand go one second. This is the operating principle of the quartz watch, which has become the representative production of quartz exploitation.
Quartz is an inorganic mineral, which mainly composed of silica, it often contain a small amount of impurities such as Al2O3, CaO, MgO. Quartz is a translucent or opaque crystal, which has very stable physical and chemical properties. Generalized quartz also includes high temperature quartz, it is also known as silica quartz, which can be the material of Sweden refractory products. Quartz stone is the abbreviated form of a name which quartz stone panel manufacturers produced, it is based on the panel main component is quartz and content reaches above 93%. So we can make the bold forecast that quartz has a good prospect in the Swedish building materials market.
The first part of the crushing process is that quartz stone normally is delivered to the feeder and taken to the crusher uniform and continuous. After thecrushing process, quartz is turned to power which is normally 7.5 to 30 centimeters in diameter. The main equipment in quartz crushing exploitation is crusher which can be divided as jaw crusherimpact crusher, hammer crusher. Based on our analysis about quartz hardness and material, we recommend using PFW impact crusher. Impact crusher crushing effect mainly based on the design of cavity type: the first level counterattack plate adopt manganese steel in order to increase the quality and the crushing effect of bulk materials; the second stage counter at back as much as possible and the lower discharge outlet near the rotor horizontal line in order to enhance the shear of the crushing effect. PFW impact crusher has a great improvement in the structure design and must have a wonderful performance in Sweden quartz exploitation crushing plant.
Quartz powderproduction ways can be divided into dry and water two kinds, all kinds of conventional specifications include: 120M, 200M, 260M, 325M, 600M, 800M, 1000M and 2000M (M mesh). In addition,quartz powder can also be processed special specifications according to Sweden customer requirements; the size distribution of the general requirements can also be processed. Sweden quartz milling plant process as follows: quartz stone ore material turned into smaller stone after crushing process, after stone roller compacted into sand, water does not stop when rolling, and then through the vibration sieve, using a bar magnet and magnet iron removal in the screening process, the last part is finished storage and packaging. Quartz exploitation milling plant main equipment is SBM ball mill, whose working principle absolutely has certain contact with its name. Ball Mill is an efficient tool for grinding many materials into fine powder. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material. In general, Ball Mill name is easy to remember and it is very popular in the Sweden Quartz powder market.
As the most responsible manufacturer which has been working on the crushing equipment and grinding equipment over the years, SBM has a wealth experience of quartz exploitation. We can provide high-efficiency machine to produce high quality quartz materials.
Its fully-enclosed layout features high integration. It integrates the functions of high-efficiency sand making, particle shape optimization, filler content control, gradation control, water content control, and environmental protection into a single syst
