R-Series Raymond Roller Mill

Raymond roller mill is also known as R series Raymond mill, it is originated in the 1880s and invented by the Raymond brothers. Nowadays the Raymond mill has advance structure with over one hundred years of development and innovation. Guilin Hongcheng has adopted new and advanced technology to upgrade R-series Raymond mill technical indicators. This Raymond grinding mill is widely used to grind any non-metal minerals with Moh’s hardness below 7 and moisture below 6%, such as limestone, calcite, activated carbon, talc, dolomite, titanium dioxide, quartz, bauxite, marble, feldspar, fluorite, gypsum, barite, ilmenite, phosphorite, clay, graphite, kaolin, diabase, gangue, wollastonite, quick lime, silicon carbide, bentonite, manganese. The fineness can be adjusted from 0.18mm to 0.038mm (80-400 mesh). We strive to maximize the efficiency of grinding mill according to your requirements including required fineness and output, if you need Raymond mill, please click CONTACT NOW below.

    Structure and Principle

    Technical advantages

    The wear resistance of the Raymond roller mill accessories is significant. Generally, many people consider that the harder the product, the more wearable it is, therefore, many foundries advertise that their castings contain chromium, the amount reaches 30%, and the HRC hardness reaches 63-65. However, the more dispersed the distribution, the greater the probability of forming micro-holes and micro-cracks at the interface between the matrix and the carbides, and the probability of fracture will also be Bigger. And the harder the object, the harder it is to cut. Therefore, making wear-resistant and durable grinding ring is not easy. Grinding ring mainly using the following two types of materials.

     

    65Mn (65 manganese): this material can greatly improve the durability of the grinding ring. It is has the characteristics of high hardness, excellent wear resistance and good magnetism resistance, it is mainly used in the powder processing field where the product needs to remove iron. The wear resistance and the toughness can be greatly improved by normalizing and tempering heat treatment.

     

    Mn13 (13 manganese): the durability of the grinding ring casting with Mn13 has been improved compared with 65Mn. The castings of this product are treated with water toughness after pouring, the castings have higher tensile strength, hardness, plasticity and non-magnetic properties after water hardening, making the grinding ring more durable. When subjected to severe impact and strong pressure deformation during running, the surface will undergo work hardening and form martensite, thereby forming a highly wear-resistant surface layer, the inner layer maintains excellent toughness, even if it is worn to a very thin surface, the grinding roller can still withstand greater shock loads.
