Some Problems during the Progress of Concrete Pump

<p>Concrete mixer has long history in China. Most of Chinese Concrete mixer manufacturer and concrete mixer supplier focus on main three kinds of <a href="http://www.dwdieselmixer.com/pro/p12.html">concrete mixers</a>. Different concrete mixer price depend on different work principles and sizes.</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:planetary concrete mixer,<a href="http://www.concrete-batching-plants.org/concrete-batching-plants/belt-type-concrete-batching-plants.html">concrete batching plant</a>s,concrete mixer,blocking making machine,concrete pump,etc. <p> <p>Gravity type concrete mixer</p> <p>Has a long history, as early as the beginning of the 20th century cheap <a href="http://www.blockmakingmachinery.org/products/DMBE-2-45-Mobile-Block-Making-Machine.html">concrete block making machine</a>, the drum of concrete mixer driven by a steam engine started to appear. After the &rsquo;50 s, reverse discharging and tilting type concrete mixer and cracked drum mixer appeared and developed. Since the gravity type concrete mixer mixing drum has a radial arrangement of agitating vane on the wall. Mixed tube around the horizontal axis rotate then inject raw material inside the cylinder. Raw material will be lift to a certain height by leaf then fall by its gravity. Through cycle of movement to mix concrete. Since the gravity type concrete mixer structure is simple, general is given priority to with mixing of plastic concrete.</p>
