At present, there exists many problems in the working process of high strength powder grinding mill, i.e, grinding speed is slow, raw materials are wasted too much and abrading the machine seriously and so on. As we all know, grinding speed determines work efficiency of high strength mill , especially for some difficult-broken materials, such as quartz. How to improve the grinding efficiency of high strength mill, this article will give you a weapon!
To improve work efficiency, firstly we have to see the whole combination of each machine, only if which works perfectly, efficiency certainly would be enhanced naturally. This is one breakthrough to improve the work efficiency of the mill. Besides, according to different raw materials, to choose different machine combination.
Look, quartz is inorganic mineral, whose main components are silicon dioxide, and often a few of impurity ingredients such as aluminium sesquioxide, magnesium oxide and calcium oxide etc, appearing to be translucent or opaque crystal, generally ivory and hard. Quartz is a kind of mineral resource with stable physical characters and chemical properties, crystal belongs to oxide minerals of three party crystal system , namely the lower temperature quartz (a-quartz), is the widest-spread mineral kind in mineral group. Extended quartz also includes high-temperature quartz (b-quartz). Quartz, also called silica, mainly is the raw material of quartz sand (also called silica sand) production, also quartz refractory material and fire ferrosilicon materials. In addition, "quartz" is a common person name.
Quartz sand actually is silicate mineral, hard, wear-resisting, stable in chemical property, and main mineral composition of which is silica, the color varying with milky white, colorless, gray, hardness of 7, brittle, no cleavage, shells-shape breaking fracture, oil sheen, relative density of 2.65, obvious anisotropy in the chemical, thermotical and mechanical properties, insoluble in acid, slightly soluble in KOH solution, melting point of 1750℃, piezoelectric property.
The role of quartz sand as industrial mineral raw material is of great importance, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.
Confronted with such materials as encounter, we should change strategy, but not to use the former grinding line. Accordingly, quartz is very durable, we won't grind it, instead that, first roast it through the rotary kiln, later grind it by mill, on this way, the production efficiency will be enhanced dramatically.
