MEG Sand-making Machine Are Applied in the Crushing and Sand-making Area
As the major manufacturer of mine crusher ,grinding mill and sand-making machine ,MEG have developed various kinds of products according to the various crushing requirements .And we should have a general knowledge of the sand-making requirements when we want to choose the quality sand-making equipment .
After years’research and development of the sand-making equipment ,MEG have found the particle requirement of the crushing materials is fine .And generally speaking , the materials with needle shape will become more easily be grinded while the stone crushing will have a strict requirement for the particle size .And the reason for this is that the cubic sand will have the edges and corners ,which will cause a interact locking effect .While the continuous movement will create the great reduction and the cubic sand will cover a larger space than the round sand ,which will reduce the movement capability of the asphalt ,materials and cement .
we can give a definition to the sand : the rock particle with the particle size of less than 4.75mm after the earth removal ,mechanical crushing and screening ,which will not include the Soft rock, weathered rock particles .
the sand specification : the sand specification will be divided into three kinds like the coarse ,mid and fine according to the fine Mx and the fine coarse sand will reach 3.7~3.1 ;and the mid sand fineness will reach 3.3~3.0;and the fine sand fineness will reach 2.2~1.6.
the sand grades : the sand grades can be divided into three kinds of Ⅰ，Ⅱ，Ⅲ 。
sand application:Ⅰkind will be suitable for the concrete of over C6;Ⅱkind will be suitable for the C30~C60 and other concrete with the requirement of Antifreeze, impermeability;Ⅲ kind will be suitable for the concrete and construction sand with the strength of less than C30.
technical features : the sand particle size is among the range of 4.75~0.15mm while have some restriction to the stone powder with the size of 0.075mm and the particle size are including 4.75，2.36，1.18，0.60，0.30，0.15 .And the particle size should be better the cubic shape and should satisfy the needle shape content .
rock used to sand-making : the sand-making rock are mainly including Granite, basalt, natural river pebbles, andesite, rhyolite, diabase, diorite, sandstone, limestone and so on .And there also have various strength and applications according to the various kinds of rocks .
nd there have many kinds of sand-making mining equipment ,which are mainly including the following 7 kinds :1. Vertical shaft crusher 2 impact crusher 3 conversable impact crusher 4.conversable hammer crusher 5 roller crusher 6.cone crusher 7.rod grinding mill .And all of these sand-making equipment have various features and applications .
As the major professional manufacturer , MEG have win its own high popularity and developed many kinds of sand-making equipment like : PCL ,VSI,VSI5X ,V.W and also the JC jaw crusher ,PFW impact crusher ,HPC cone crusher and so on. VSI5X series crushers are widely used in metal and non-metal mine, concrete, fireproof material, abrasive filler, frit, construction aggregate, sand, metallurgy and other industry. It is used for mid & fine crushing and suitable for various hardness of ores and rocks ,such as iron ore, nonferrous metal ores, carborundum, bauxite stone, quartz sand, brown alumina, Expanded Perlite, whinstone and so on. Based on the German technology and our multi intellectual property, we company has developed this new kind of high-effiency crusher . And VSI5X Series Crusher has integrated three types of crushing into a single whole, which has become a new kind of high-efficiency crusher and core equipment . And MEG VSI5X will surely promote the dynamic energy for the sand-making market !
