Detailed introduction

sfssdf

Compared with similar products, G30 liner has the following outstanding features:

1. Friction coefficient 0.25;(tested by Luoyang Mining Machinery Engineering Design Institute)

2. The wear amount is less than 2.8 × 10-6 cm3/KN;

3. Compressive strength 3Mpa;

4. Hardness 55-65HD fully comply with GB/T10347-2002 standard.

Due to the increase of G30 friction coefficient and the decrease of wear rate, the cost performance of its products has been improved a lot, which brings higher benefits to users.
