The survey and analysis show that, the development and utilization of non-metallic mineral products in China has been had 50 years history, and so far, discovered non-metallic mineral with the economic value are more than 100 kinds with the origin more than 5,000. As an important industrial resource, non-metallic mineral accounted 70% of the total mineral extraction. Most of the non-metallic minerals can be directly used in agriculture, chemical, paper, plastics, rubber and coatings products after crushing and classifying.


The sand maker has a strong practicality and it is widely used in highway, railway, port construction and infrastructure sector applications. Currently, there are many kinds of sand making machine products in the domestic market. From the international point of view, the advanced technology of the vertical shaft impact sand making machine is reflected in three aspects: flexible mechanical properties and excellent wear-resistant material and part design and effective dust control.
Wear-resistant material and part design: Due to the design of material pad on the vertical shaft impact sand making machine to replace the liner as wearing parts, the improvement of the service life of the wear parts can be decomposed into parts design and wear-resistant materials application aspect. Dust control: The sand maker produced by Hongxing adopted unique air circulatory system, which greatly reduces the amount of outside air exhaust to reduce dust and it is environmentally friendly. Meanwhile, the equipment reserved space for installation of a variety of specifications of secondary dust clearing equipment.
