The roll skin of the roll crusher of Huashengming is outstanding in wear resistance, and its design and material selection are all centred on prolonging the service life, with the following specific advantages:

1. High-strength wear-resistant materials

The roll skin is made of high chromium alloy, multi-alloy wear-resistant ductile iron and other special materials, and the hardness of the surface layer can reach HRC50-55, and the wear resistance is enhanced by quenching process. For example, high chromium composite roller skin outer layer of high chromium alloy, the inner layer of ductile cast iron, designed for fine crushing, wear resistance significantly better than ordinary materials.

Some roller skins are also made of high-chromium manganese steel with patented technology. By optimising the alloy composition (e.g. increasing the content of C and Mn, and adding elements such as Ti, V and Mo), it further enhances the hardness and impact-resistant ability, and prolongs the service life to 2-3 years, which is far more than the average level of the industry.

2. Structure design and process optimisation

The thickness of the roll skin is designed scientifically, for example, the initial thickness is 110mm, and the roll skin will be scrapped only when it is worn down to less than 30mm, which effectively prolongs the replacement cycle.

Some models are equipped with automatic cleaning device and hydraulic adjustment system, which reduces material adhesion and abnormal wear and maintains even force on the surface of roller skin.

3. Actual application effect

According to users’ feedback, the roll skin of Huashengming can still maintain stable performance when continuously processing high hardness materials (such as granite and basalt), with high crushing efficiency and even finished product size.

Through high quality materials, advanced technology and intelligent design, the roll skin of WMS roll crusher achieves high wear resistance and long service life, which is especially suitable for high hardness and high intensity crushing operation. Users can choose different roller skins according to the material characteristics and combine with regular maintenance to maximise the benefits of the equipment.
