Wear parts insert TIC material, 2-4 times lifetime, highly recommended!

1. Cast grinding ball/Cylpeb

We produce the cast grinding ball / cylpeb in 3 types: High Chrome, Media Chrom and Low Chrome Alloy. It is suitable for dry grinding ball mill, used in cement, brick making, construction material making and mining. The size ranged from 10mm to 140mm, with high hardness, low breakage and good wear-resistance.
All the grinding media provided by Sinco backed with the ISO 9001 Certificate and shipped only after passing our quality control procedures.

3.Manganese steel ball mill liners

As the widest used ball mill liner, Sinco manganese steel liner plate is in the application of cement plants, gravel firms, coal gangue treatment plants and block plants.
Advantage of high manganese steel liner plate
1. Long service life, light weight, thin thicknessand power consumption.
2. Fast replacement and maintenance, easily installed and need less labor work.
3. Widely used for high, medium, and weak magnetic mineral.
4. Attached on the inner wall of cylinder by magnetic force, no pulp leakage and highly efficient.
5. Can be used for nonmagnetic mineral substance, but certain quantity of ferromagnetic substances such as broken steel balls and scrap iron must be added form protection layer.

4.Abrasion resistant rubber liner plate / ball mill rubber liners plate

The rubber liner plate for ball mill cansatisfiedthe overflow type,grid-type and multi-chamber ball mill type. The maximum specification with wear-resisting rubber lining board of ball mill is Φ5500X8850. It has been used in the field of black metal mines,non-ferrous metal mines,chemical mines,golden mines and steel smelting,nonferrous metal smelting,fertilizer,cement,industries and so on.
Advantage of rubber liner plate:
1) less weight than all steel lining.
2) reduced structural and bearing loads.
3) lower operating costs.
4)easier to replace.
5) reduced noise.
