Pearlitic Cr-Mo Alloy Steel Castings AS2074L2C Grinding Mill HRC34-43
1. Material:.Cr-Mo Alloy Steel(Medium C)
2. Standard:AS2074/L2C
3. Hardness:HRC34-43,
The Combined Self-fastened Boltless Ball Mill Liners
This product, invented by Mr. Chen Changshun, senior engineer and the director of the company,
is known as “China Best Liner”.It includes two parts, high wear resistance boltless plates, and highly
expandable riveting plates, which are self-fastened and strengthened to with stand impact from
mill balls.
We possess famous patented product Combined Selffastened (Boltless) Ball Mill Liners, or called
CHINA BEST LINER.
In 2012, we registered a new patent about Liner Technology.
In December of 2000, we successfully registered the international patent in Canada.
In 1988 and 1997, we claimed domestic patents for ball mill liners .
The outstanding advantage of our liners is boltless.
The general advantages in ball mills are as follows:
Output Increased | 5~20% |
Power Consumption Reduced | 5~20% |
Maintenance Decreased | Above 98% |
The liners are easily installed and existing mills need no modification. | |
Materials 1: Double-Media Quenching Chromium-Molybdenum Alloy Steel Series
We specially design the material for ball mill liners in mines, coal fired power plants and cement
plants, etc
With our special double media quenching process, the material can not only achieve ideal hardness
(HRC48~55) but also ideal toughness value (AK30~100J). It can completely meet the requirement of
liners of large and middle size ball mills at home and abroad. The match of Middle Chrome Linersand
High Chrome Cast Balls has been the typical model in coal mills and cement mills.
Meanwhile,the material is applicable to the teeth plates, armored plates and hammers of crushers and
excavator bucket teeth.
Materials 2: Pearlitic Chromium-Molybdenum Alloy Steel Series
The Pearlitic Chromium-Molybdenum Alloy Steel Liners are widely used in AG Mill,SAG Mill and
Ball Mills.
Hardness: HB310-375 (equivalent to HRC33-42)
Impact resistant Value: Ak≥60J (60×10×10mm) in normal ambient temperature.
We can produce pearlitic Cr-Mo steel as per AS2074 Gr. L / 2B.
Materials 3 : High Chrome White Iron Series
High Chrome white iron we can produce include 15%Cr, 18%Cr, 20%Cr and 26%Cr. Under same
working condition, the wear performance of High Chrome mill liners is four times of that of high
manganese steel liners and twice of that of low Chrome alloy steel liners.Meanwhile, we can
produce high Chrome castings as per AS2027, ASTM A532 and BS4844.
