Raymond Mill has been widely used in the processing of non-metallic minerals since it was introduced into China for more than 20 years. However, with the extensive development of non-metallic minerals in the field of ultra-fine powder applications, downstream companies have increasingly higher requirements for non-metallic mineral products, especially with higher requirements for product fineness, which has made traditional Raymond mills Looks weak. To this end, Dalier Heavy Industry Technology Department conducted in-depth analysis and research on traditional mills, and solved many fatal defects such as frequent maintenance, high maintenance costs, and substandard grinding of traditional Raymond mills. The new ultra-fine Raymond mill with crushing, grinding and super-fineness. Because of its high efficiency, low energy consumption, ultra-fine, small footprint, low capital investment and environmental pollution, etc., it is widely used in the grinding of mineral materials in metallurgical, building materials, chemical, mining and other fields, suitable for Processing of various non-flammable and explosive minerals with a Mohs hardness level below seven and humidity below 6%, such as gypsum, talc, calcite, limestone, marble, potassium feldspar, barite, dolomite, granite, kaolin, bentonite , Maifanite, bauxite, iron oxide red, iron ore, etc.
