Ring medium speed mill main features. Ring medium speed micro powder mill efficiency and low consumption. In the materials, power, the same situation fineness, 40% higher than airflow mill and mixing mill production. 2. Ring medium speed micro powder mill long service life. Under the same materials and fineness of the case, than the impact crusher and turbine crusher wear parts and long service life Raymond machine, generally up to 1 year. 3. Cavity without rolling mill, no screws. There is no bearing its seals and wearing loose screw easily and destruction machine and other issues. 4. Product fineness can reach a d97≤5μm. River gravel grinding machines selected river pebbles need is a natural stone, taken from the experience of thousands of years ago after the crustal movement generated by the old riverbed gravel mountain ridges Raymond 6r, flash floods experiencing long-term impact, water Handling the process of continuous extrusion, friction formation. River gravel surface density of 2.5g / m3, a bulk density of 280kg / m3, robust indicators of 95-99.8%. River gravel main chemical composition is silicon dioxide, followed by a small amount of iron oxide and small amounts of manganese, copper, aluminum, magnesium and other elements and compounds, the quality of hard Raymond, with natural stone characteristic compression, wear abrasion resistant, It is an ideal building material. After crushing river gravel as concrete aggregate 3016 Raymond, building materials market has a certain history and widely promoted, its main purpose is twofold: industrial and civil construction of concrete aggregate and road construction the horizontal stabilizer layer material. River gravel storage usually abundant and low mining costs, behind its economic development potential, revealing a huge demand for high-quality sand. After river gravel crusher later, it is mainly used in many sectors in mining, smelting, building material, highway, railway, water conservancy and chemical industries, breaking strength not exceeding 320 MPa of various materials. If you want river gravel grinding ground, you first need to go through river gravel crusher into the Raymond maximum feed size with the size, and then Raymond milling. When selecting Raymond model, we must first clear the milling of raw materials they need, when production and other issues.
