Why the Price of Sand and Gravel will Continue to Rise
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.
The Difference Between Wet and Dry Process of Manufactured Sand
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 Properties
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.
500t/h Dolomite Crushing Plant
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 Production Process
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.
Stacker Conveyor for Sale
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.
Material Conveying System of Mineral Powder Processing Plant
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.
Ground Calcium Carbonate Manufacturing Process
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).
500t/h Limestone Crushing and Sand Making Plant
The main crushing equipment adopts advanced hydraulic control technology with stable and reliable performance. The limestone crushing plant adopts two-stage crushing and sand making process, and modular installation, which not only saves the land area and installation period, but also facilitates the inspection and maintenance of the equipment.
