The single particle size of desert sand does not meet the requirements of concrete use (standards and specifications). If desert sand must be used, it can be mixed with other sizes of sand to form a good particle gradation and improve the performance attributes of desert sand.
What are the negative effects of mining and aggregate production on the environment? How can mining and quarrying reduce the environmental impact? This article shares 6 ways to make mines and quarries more sustainable.
In recent years, the price of China’s sand and gravel market has continued to rise, which directly affects the progress of project construction. What caused the tight supply of sand and gravel? There are 3 main reasons for the increase in the price of sand and gravel.
Manufactured Sand Wet Process
Advantage
There is no restriction on the mud content of the masterbatch.
The mud content of the finished material is low and stable, and the methylene blue value is easy to control and stable.
The surface of manufactured sand is clean.
The dust from sand making and washing is easy to control.
Manufactured sand is a kind of artificial sand, which can control the stone powder content and gradation requirements in accordance with the national standards and technical requirements of project quality, which can effectively meet the actual needs of different projects.
In July 2020, it obtained the mining right of the dolomite mine for building stone materials, with a recoverable reserve of 310.631 million tons and a production scale of 20 million tons per year. With the smooth delivery of finished aggregates of different specifications to storage, the 500-600 tons per hour dolomite aggregate crushing plant has recently entered the trial operation stage.
Titanium dioxide (TiO2) has stable physical and chemical properties, excellent optical and electrical properties, and excellent pigment performance. TiO2 is the most versatile white pigment with the best application effect. This article will share the production process of titanium dioxide pigment.
The stacking conveyor consists of a conveyor installed in a heavy-duty truss, which is used to transport solid bulk materials from the bottom to the top of the stockpile. It can be moved flexibly through a traction device (towing vehicle) or its own drive device (crawler/wheel drive), and can be used as a stand-alone machine or combined with other equipment. Compared with wheel loaders or screw conveyors, stackers are more efficient and have less dust.
The project is the largest local mineral powder processing plant in Jamaica. It provides a large amount of material requirements for local infrastructure construction. It uses 9 truss belt conveyors with dust-proof, rain-proof and safety protection functions.
The main component of limestone is calcium carbonate, which is a sedimentary rock made of calcite or aragonite minerals. Mined limestone (calcite, limestone) is directly ground into powder to make ground calcium carbonate (GCC).
