Describe the Knowledge of Diesel Concrete Mixer

<p>Sandstone is the main ingredient of concrete (about 80%), and the domestic market shows a large and increasing demands for sandstone from 2011, and the price of medium sand (2.3mm~3.0mm in granularity) rises from 78.4 yuan/ton to 92.5 yuan/ton in one year <a href="http://www.portable-concrete-mixer.net/portable-concrete-mixer/mobile-concrete-mixer.html">Mobile concrete mixer</a>, about 18% up.</p>Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:<a href="http://www.daswellmixer.com/product/Concrete%20_Mixer/20130929/26.html">concrete mixer price</a>,<a href="http://www.daswellmixer.com/product/Concrete_Batching_Plant/20130927/19.html">concrete batching plant</a>s,concrete mixer,blocking making machine,concrete pump,etc. <p> <p>According to the incomplete statistics of China Sand-Stone Association, the domestic sandstone consumption has risen from less than 500 million tons in 1981 to 12 billion tons in 2013, and the annual sale has risen more than 20 times. Based on this speed, the sandstone will be in shortage in the following years even if its production is improving rapidly.</p> <p>This situation also brings opportunity to artificial sand production. The so-called artificial sand is granular ore less than 4.75mm in granularity produced by crushing and screening equipment. The artificial sand has rich raw material source, and it can be said where there is stone, there is sand. In addition, the municipal construction wastes and mining tailings also can be produced into artificial sand.</p>
