The whole structure of hollow brick making machine

<p>2. Hollow baking-free brick:</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:diesel <a href="http://www.doubleshaftconcretemixer.com/">concrete mixer</a>,portable <a href="http://www.daswellchina.com/products/concrete-mixers/diesel-concrete-mixer.html">cement mixer</a>,We will provide you with the best product and service. <p> <p>Hollow baking-free brick, a new type of baking-free brick <a href="http://www.dwconstructionmachine.com/en/Products/Block_Making_Machine/30.html">mobile <a href="http://www.dwconstructionmachine.com/en/Products/Block_Making_Machine/30.html">block making machine</a></a>, is also called perforated brick. As to its structural feature, there are many round holes and square holes on the brick with hollow ratio of 20 percent to 50 percent. With the characteristics of low density, light weight, materials saving, and low cost, it can reduce the weight of buildings themselves by a large margin and improve performances of heat preservation and heat insulation. Therefore, hollow baking-free brick is the development direction of baking-free brick. With the development of lightweight brick, the utilization of hollow type will be raised.</p> <p>3. Microcellular foaming brick:</p> <p>Microcellular foaming brick is the new baking-free brick molded by foaming technique. Micro spherical closed air holes with diameter less than 1 mm are filled in the interior of the brick. With low density and heat retaining property <a href="http://www.dwdieselmixer.com/pro/p13.html">mobile concrete mixer</a>, it is suitable to make thermal-insulating wall.</p>
