The emergence of sand making machine, crusher and other mineral processing equipment has gradually replaced the existence of natural sand with manufactured sand. The majority of users combine various mechanical equipment into a complete sand production line while making full use of their advantages.
The appearance of the sand making production line has promoted the improvement of the quality of the machine-made sand, but how to control the production of materials that can be comparable to natural sand and gravel? Below is a brief analysis performed by SMMVIK Machinery.
First, we should control the composition of materials processed by the sand making machine. Is the weak particle content too much too little will have different degrees of influence on the strength of concrete, general building sand is required to concrete internal and external content requirements respectively do not exceed 15% and 5%.
How to reduce the content of soft particles can take this step. First, select the site for the selection of sand and stone processed by the sand production line, peel off the useless layer of soft particles, and then mine the remaining useful particles. And then the quality control of sand and gravel raw materials. In the process of modern building construction, the construction link of hydraulic concrete can not be doped with alkali active raw materials, and the sand raw materials just meet this requirement.
If the quality of sand and stone materials meets the requirements, the grain type and wear resistance are usually good, or the rock with a larger proportion and a smaller thermal expansion coefficient and elastic modulus. Generally, when selecting rocks, different sites and mining methods will have a great impact on them. The quality of rock will also directly affect the quality of concrete, and even the production cost of the whole sand production line.
The above are the basic requirements of SMMVIK mechanical summary. Only by using the sand making machine reasonably can the sand making machine equipment produce materials that meet the target. SMMVIK Machinery is a manufacturer specializing in the production of sand making machines, It has many years of experience in the research and development of excellent sand machines, and also has a complete set of configuration solutions for machine-made sand production lines. If you are interested in our equipment, welcome your inquiry, we look forward to your arrival.
