Which ores can be processed into machine-made sand

Sand and gravel are an important building aggregate in the construction industry. However, in recent years, the exploitation of natural sand has been restricted, and the demand for machine-made sand has soared. Many bosses want to switch to investing in the sand and gravel industry. So what raw materials are better for machine-made sand? This article will introduce you one by one 1. What is the * raw material for machine-made sand?
     There are many types of machine-made sand raw materials, among which the harder stone materials are river pebble, granite, basalt, iron ore, etc.; the softer materials are weathered rock, limestone (bluestone), coal gangue, dolomite, shale soil , hemp ancient stone, gypsum, calcium carbonate, etc., are relatively good raw materials for sand making. Customers can choose the raw materials for machine-made sand production reasonably according to the supply demand and market price, so as to obtain a larger profit space.
     2. What kind of machine-made sand is considered as good machine-made sand?
     Whether the machine-made sand is uniform and non-sticky: In the sand and gravel industry, the finished particles are required to be uniform and non-sticky, so the sand making machine can be reasonably configured in the production line to improve the quality of the machine-made sand.
     Whether the machine-made sand is clean and free of impurities: It is required that the content of machine-made sand and gravel powder is small and the content of mud is small. Therefore, a sand washing machine can be reasonably configured in the machine-made sand production line to remove dust and impurities from the machine-made sand.
     Whether the machine-made sand meets the national standards: machine-made sand is generally used in infrastructure, so there are strict requirements for quality.
