Cone Crusher Concave/Liner

Cone Crusher Mantle/Liner

Mantle/Bowl/Concave

We can provide you with various brands of Concave , also can customize and produce according to your working conditions

The rolling wall is the main part that breaks the wall and works together with the broken cone to break the material. Because it is fixed, it is also called a fixed cone.

If you don't find the product you need on the website, please email us（info@lyzhili.com）, because we are a customized factory for crusher spare parts.

we can provides comprehensive material selection for you

Bimetal compisite material

Feature:

This material adopt special technological process to make two material with different property integrate in the same time when they are liquid state.

The bonded area could reach 100% and the impact toughness of the bonded area can get more than 14J/cm2 ,the working part use high Cr casting iron and adopt directional solidification to make Cr7C3 which included in high Cr casting iron perpendicular distribute to the working surface .

The hardness could reach to HRC62-65,and the impact to toughness(AK) is above 30J/cm2 ,It can resist the cutting from AL2O3 and SiO2 perfectly show the high anti-friction property . the hammer handle with high toughness and perfect combined mechanical properties.the material have both high anti-friction and safety property and solve the contradiction between the hardness and toughness effectively ,make the spare parts fit the wicked working condition.

The lifetime of the hammer which made from bimetal composite material is 2-3 times than the lifetime of normal high Mn hammer .Specially suit for the big crusher hammer ,blow bar and liner of big mill .The effect will be prominent in the wicked condition .It is widely used in limestone ,cementclinker,iron,sandstone,gangue ,basalt and so on.

High Manganese Steel

Feature

High manganese steel refers to high alloy steels containing more than 10% manganese. The biggest features of high-manganese steel are:

The greater external compressive stress or impact load, the more conducive to the formation of hardened layer, so the higher the wear resistance of the casting;

With the gradual wear of the hardened layer, new work hardened layers will continue to form under the influence of external compressive stress or impact loads. Therefore, it is suitable for making wearable spare parts that are subject to high impact load and wear for a long time, and is widely used in metallurgy, mining, building materials, railways, electric power, coal and other broken grinding equipment.
