Recently, in order to vigorously promote the utilization of machine-made sand and promote the healthy development of machine-made sand industry, the Department of water resources of Henan Province, the Department of housing and urban rural development, the Department of natural resources, the Department of industry and information technology, the development and Reform Commission of Henan Province, the Department of ecological environment, the Department of transportation, and the market supervision and Administration Bureau of Henan Province jointly issued the guide on promoting the development of machine-made sand industry and promoting the application of machine-made sand Guiding opinions (Trial) (hereinafter referred to as "opinions"). According to the opinion, the newly-built enterprises should have an annual production capacity of more than 3 million tons of manufactured sand, and give priority to those with an annual production capacity of more than 5 million tons.
The opinions encourage enterprises with large scale, strong technical force and good reputation to enter the field of machine-made sand. The newly-built enterprises should have an annual production capacity of more than 3 million tons of manufactured sand, and give priority to those with an annual production capacity of more than 5 million tons; for the project of comprehensive utilization of mining waste rock, waste slag, industrial and construction wastes to produce machine-made sand, the production capacity should reach more than 1 million tons. It is necessary for the enterprise to have the necessary sand production mechanism, such as full sand screening, dust removal and production mechanism.
This is undoubtedly good news for the machine-made sand industry, and it is the policy support for the investment of machine-made sand. Machine made sand is a kind of rock, mine tailings and industrial waste slag particles with particle size less than 4.75mm, which is made by mechanical crushing and screening after soil removal treatment, but does not contain soft and weathered particles.
Machine made sand production needs sand making machine. The choice of sand making machine determines whether the later production can be carried out smoothly and stably and the quality of finished sand is good or bad.
As a manufacturer of crushing sand grinding equipment with more than 30 years of R & D and manufacturing experience, kfida series impact breaking sand machine has a wide market share and good reputation in the field of machine-made sand. It has established a number of machine-made sand production lines at home and abroad, and has processed pebbles, pebbles, granite and other stones, or tailings, stones, stone chips, waste materials, etc The mechanism sand of river sand makes up for the shortage of river sand.
In view of the current severe environmental protection situation, cofeta has also developed a fully closed machine-made sand production line system -- Vu building type sand making system. The system adopts highly intensive tower type fully enclosed layout, integrating sand making, particle shape optimization, stone powder control, grading adjustment, water content control and environmental protection treatment, which not only significantly improves the production efficiency, but also realizes the grain shape and grading of manufactured sand The improvement of various indexes, such as powder content, is specially designed for the production of fine machine-made sand. It has been widely concerned by many powerful sand and stone production enterprises. At present, many enterprises have put into production the VU sand making system, so you can make an appointment to visit the site.
Crawler crusher has higher flexibility than fixed crusher. Crawler crusher is directly driven by engine, which has higher efficiency and energy saving.
