Get the price of machines: [email protected] ,for more details, here is our skype: billchanglei123 Chang Lei crushing equipment has many models for different requirement, we can provide a full range of products and services. Our concave and mantle are made of alloy manganese steel composed of Mn13,with the advantages of impact resistance, friction resistance, compression resistance and long service life. We successfully solved the supply problems of fine aggregates with a variety of specifications for concrete and provides a steady stream of high-quality concrete sand and gravel aggregate for the highway, port construction, hydroelectric dam construction. The shape and size of the parts mainly depends on two factors: one is the force; the other is the manufacturing process of parts and appearance. Chang Lei alloy wear-resistant parts have the following features: its service life can be more than five times of that of similar products, crushing efficiency increased by 30%. Product quality is in the hands of every one ,we need to do a serious and dedicated in every detail. Shanghai Chang Lei parts mainly adopt high-manganese steel and other materials, greatly enhancing their toughness and wear resistance performance.
