In the past year, the mining of river sand is prohibited, and the price of natural sand has skyrocketed. Sand and stone, as an important infrastructure material in various industrial fields, will also be in great demand in 2020. In addition to construction waste, mine tailings and other waste materials, they will be processed into sand and stone, and stone powder is also concerned by everyone. What is the difference between machine-made sand and stone powder? What procedures does stone powder processing plant need? How much does a stone powder processing equipment cost? Here is a detailed answer for you.
1. Can stone powder replace mechanical sand?
Machine-made sand: it is made by mechanical crushing, screening, particle size less than 4.75mm, but does not include soft, weathered particles;
Stone powder: it is the content of particles with particle size less than 75μm in machine-made sand. For example, for C30 concrete, the content of stone powder is 10-15%, and for C50 concrete, the content of stone powder is 5-10%.
Can stone powder replace machine-made sand? It is impossible to simply replace machine-made sand with stone powder directly, because the high content of stone powder will directly affect the quality of concrete. Generally, after sand making and cleaning, the content of stone powder is controlled within a reasonable range, which can be used in rubber, paper making, ceramics, cement, glass, craft construction, decoration and other fields.
2. what are the stone powder processing equipment?
At present, the market situation, to open a stone powder processing plant, the profit is naturally there, but the profit is not big, depends on the overall operation, processing stone powder equipment configuration, of course, can not be careless, what is the stone powder processing plant equipment? Detailed introduction is as follows:
01. Stone powder sand making machine;
For the stone powder with large particle size, it can be reprocessed, mainly for sand making and shaping. The finished stone powder has good shape, uniform particle size and low needle flake content. The working mode of stone beating stone,stone beating iron can be freely converted, and the production efficiency is higher. Energy saving and environmental protection.
02. Stone powder sand washing machine;
Clean the finished stone powder, remove impurities, improve the quality of finished products, control the content of stone powder, high cleaning rate, water and electricity saving and more environmental protection.
3. A stone powder processing equipment how much?
Stone powder processing plant equipment is diverse, complete models, the cost of raw materials is different, output, feed size and discharge are different, and different manufacturers of equipment in the use of equipment performance, quality and other conditions are unstable, so the price of stone powder processing plant equipment varies.
Specific stone powder processing equipment how much money, can be consulted at any time, that is, enjoy factory price preferential activities, sales managers contact you, Sand Mine Machinery equipment is directly supplied, there is no intermediate redundant link, cost, so many customers said that the price is very preferential, and the selection of high-quality raw materials, exquisite workmanship, to ensure the quality of equipment.
4. Stone powder processing plant need what procedures?
To open the stone powder processing plant must go through the relevant procedures, legal production can ensure that the follow-up will not be forced to close or fine the situation, because the provisions of each region will have certain differences, the following can be used as a reference, according to the local prevail.
01. Industrial and commercial department nuclear name: need to upload personal ID card to the factory bureau to apply for the name of the pre-approval notice, the company to apply for the industrial and commercial Bureau to get the form, and also have the signature of shareholders;
02. Security administration approval: security department according to the production environment to do the investigation of security risks;
03. Assessment of environmental Protection Bureau: assessment link of environmental supervision department, and relevant certificates for handling;
04. Industrial and commercial departments for business license: approved name - submit information - get a license;
05. Tax authorities for tax registration certificate: after registration, first for tax reporting, monthly accounting and tax declaration to the tax authorities;
06. The bureau of Land and Resources do mining license: mining license will stipulate the scope of exploitation, state-owned resources are limited.
If you also have the intention to invest in the establishment of stone powder processing plant, you may wish to consider SMMVIK Machinery manufacturers, equipment are in stock, can come to the company for field investigation, check the overall situation of equipment, welcome to call at any time, there are sales managers for you to arrange.
