Concrete mixer pump has never been surpassed

<p>The basic principles of the <a href="http://www.daswellmixer.com/product/Concrete_Batching_Plant/20130929/21.html">concrete mixing plant</a>:</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/Block_Making_Machine/20130929/34.html">block making machine</a>,<a href="http://www.dwconstructionmachine.com/">concrete mixer</a>,We will provide you with the best product and service. <p> <p>1).Maintain stable raw material origin, variety, and stable performance;</p> <p>2), the use of clay less suitable thickness, sand with reasonable level will not increase the cost of concrete unilateral, may reduce the cost;</p> <p>3), fly ash, slag admixture reduce costs. A mixture of the two concrete better performance, lower cost, the mixing ratio experimentally determined.</p> <p>Concrete mixing station raw material control method</p> <p>1, the cement</p> <p>1), according to standard strength, setting time. Results contrast with previous experimental results, if any changes, to adjust the ratio.</p> <p>2), with the same admixture samples, testing each batch cement adaptive changes in the station (you can paste fluidity comparative experiments) <a href="http://www.daswellmixer.com/">diesel concrete mixer</a>, such as changes, for active admixtures do experiments (for concrete), adjusted to actual changes in concrete mixing ratio.</p> <p>2 <a href="http://www.daswellchina.com/products/othermachine/concrete-pump.html">concrete pump</a>, the sand</p> <p>1), according to the standard detection clay content, fineness modulus. Comparison with the previous results, adjusted according to the changes in the ratio. Clay content increases, the increase in water consumption, the amount of cement, or increase the dosage of admixture. Fineness increases, increasing the rate of sand; otherwise reduce the rate of sand.</p> <p>2), the apparent ways of looking at the state of the sand particles. Whether the larger particles and texture, hand camera test particle strength. Many particles of low intensity, should be carefully examined. This sand caution. Stones by standard sieving, crushing value, flakiness test. Graded change, to change the sand rate adjustment. Such as the production of high-grade concrete, to strictly control the indicators.</p>
