Main kinds of rock crushing plant are follows: pebbles sand making production line, granite production line, limestone production line, stone crusher production line, with the rapid development of regional economic construction, industrial construction, infrastructure construction, high quality of artificial sand required area is very large, our company grasp market opportunities, provide excellent services to the large and small gravel companies across the country, and bring them more profits and wealth. Others including Drew Houston, offer their opinions as well. The sand production equipment is more refined, specialized, high-performance .a variety of ore resources distribute over across the country, such as limestone, iron ore, granite, basalt, river pebbles, pebbles, diabase, etc., because of their different properties such as hardness, humidity characteristics, the corresponding gravel production lines are more and more refined, the targeted crushing equipment selection is also growing, according to the ore resources features customers required, investment scale, site characteristics, our company select the process line target the customers configuration, so that the different sand production lines can achieve the purpose of most reasonable, economical utilization. 2. The artificial sand product specifications are diverse to meet the different applications needs. Construction requires the particle size of gravel and sand are different, such as 1-3, 2-4, 3-6 and the other specifications, the PCX sand making machine our comapny produced can produce different specifications qualified mechanism sand products, all of them meet the needs of different construction applications. 3, The investment is relatively small, the cost recovery period is short, the return rate is high. Such as a sand and gravel production line whose daily output is 5000 tons, we only need to invest 15 million yuan, and from start building to put into production items, only 100 days duration will be able to make a profit producing benefits. The benefits of these advantages and benefits quickly are fuly confirmed by the long term rock crushing plant experiences of our company, 4, Energy-saving and low consumption, low noise, more environmentally friendly. Accompanied with the rapid developmetn of economic construction, regional industrial development, the corresponding result is the deterioration of the ecological environment. energy saving and environmental protection are increasingly being paid attention by the government, enterprises, social, compared to the same kind products, the artificial sand production line our company produced not only have the advantages of excellent crushing rate, high production output, but also pay more attention to the environment friendly design, we adopt the totally closed design, reduces noise, install the dust removal devices, and really achieve the purpose of building green artificial sand production line.
