VSI crusher carbide bar inserts
Compatiable with most makes of VSI crusher Sandvik, Metso, Terex, McCloskey, Cemco, Superior, Spokane,
Stedman, Astec, BHS, Magotteaux, Weir, etc.

OEM &ODM are highly welcomed upon your drawing or sample.

Tungsten has high plasticity, a low rate of evaporation, a high melting point, a strong electron emission ability.
It has the highest melting point of all the elements and melts at 3422ºC.

The Carbide Bars are mounted into the slot of the VSI Rotor Tip, which can be formed a tool like Hammer
Head, to break the stone, rock and Ore Blocks.
Tungsten carbide bar, improved strength but low cost and more wear life than traditional steel bar.
Carbide is an extremely durable substance that substantially extends it's life up to 20 times over standard
carbon steel bar.

Why Do Our Rotor Bits And Carbide Bars Perform Much Better Than The Others?
Except standard grade, we custom-make Grade of the carbide by analyzing customer's local/site working
conditions (e.g. feed size, type, gradation, hardness, screen size, etc).
That means we customize the grade from the first step mixing raw materials, control the temperature and
pressure when sintering, and finally use different welding techniques to make our wear parts suitable for
certain working condition.
Our Factory is located in ZIGONG City(China Tungsten Carbide Production Base), Sichuan Province.
The quality stability of carbide bar is the core for crusher wear parts. How to prolong its life span is what we
care most.

Our Standard Carbide Grade

Grade: MT6Z

Hardness: 90.5 - 91.0HRA

S.T.R.: 1800 - 2000Mpa

Density: 14.90g/cm3

Grain size: 1.0 - 1.6μm

The Ultimate Crushing Solution

VSI Crusher are unique due to its crushing process. Whereas most other type of crusher use metallic parts to
crush, VSI uses the rock fed into the machine to crush itself. This crushing process produces the best shaped
aggregates. The high velocity impact crushing achieved in VSI improves the shape of stone, reducing product
moisture and thus easing the screening operations. With rock-on-rock crushing action there is advantage of
cost savings, durability and unmatched performance in variety of crushing tasks.


We provide carbide bar well welded rotor bits as a set of wear part to make sure overall quality is
superior to most competitors.

Q&A:

1. Why You Say Your Tungsten Carbide Bars Have Much Better Performance?
-Coarse enough of grain size to be favorable for welding, especially in cold weather.
- Lower Cobalt without broken, longer wear-resistance.
We never stop finding better grade with much longer wear-resistance to save clients' cost. Now we are testing
new grade with coarse grain size for Europe market, it works well. Also we are making another 3 kinds of new
grade to test and compare with current grade. If it goes well, next step we will try to test it for America market first.

2.How You Control the Quality of The Carbide Bars?
-Much strict control on scrap carbide to ensure stable quality of carbide powder.
All is from qualified carbide rods with grain size 0.8-1.0um, like end mill, reamer, drills. Other carbide
manufacturers usually use carbide drill bits or anvil with grain size 1.2/1.6/2.0 mixed.
-Our special creative sintering process to ensure uniform grain size 2.4um.
Carbide manufacturers usually sinter it by Intermediate Frequency Furnace with temperature 1500ºC, that the
heat-difference can be 70-80ºC causing non-uniform grain size. We use Vacuum Sintering Furnace with "secret"
temperature without heat-difference to ensure uniform grain size 2.4um.

3.Do You Accept OEM&ODM?
Yes, for sure, we can cutomize the grade and shape upon your drawings or samples. Such as, make the grain coarse or add
more cobalt to increase its hardness. Make balance on hardness and toughness.
