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.

VSI Rotor Tips

With tungsten carbide bar welded, the rotor tips are widely used to crush various kinds of materials, such as
Granite, Basalt,Limestone,Quartzite, Gneiss, Cement Clinker, Concrete Aggregate, Ceramic Materials, Iron Ore,
Gold Ore, Cooper Ore, Corundum, Bauxite, Silica etc.
 

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.
