Alloy Steel Castings Plates For Jaw Crusher With Sandblasted Treat
1. Alloy: 15%Cr.
2. The Jaw Plates are cleaned, sandblasted with a nice surface without any obvious visual defects that
can avoid the normal working of the castings.
3. Hardness: more than HRC60;
4. Microstructure: Fine Martensite + Carbide + retained Austenite(≤6%)
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 withstand impact from mill balls.
We possess famous patented product------
Combined Self-fastened (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. | |
The additional advantages in cement mills are as follows:
No leakage of slurry |
No repairs during service periods |
Better reliability and stability |
Production Improvement |
Noise reduction |
In the recent 20 years,our liners have been widely used in large,medium and small ball
mills in Chinese power generation, mining, cement,chemical engineering and metallurgical
industries and super fine pulverizing equipments. It is the only recommended liner product
in the latest standard of the electric-power industry in China.
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 Liners and 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.

Jaw plates and cheek plates for jaw crushers,blow bars and impact plates for impact crushers,
cone liners for gyratory crushers,hammers for hammer crushers and concaves and mantles for
cone crushers.Depending on the specific working conditions,all wear parts can be ordered as
Manganese Steel,high Cr cast iron or Cr-Mo Alloy Steel.
