Product Description

Product Description

 
HPGR also named as high pressure grinding roll mill, is an energy-efficient crushing equipment used to reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed's density to 80% of its solid volume, exceeding its compressive strength with equal pressure being applied to particles of all sizes. HPGR is widely used in grinding cement clinker, limestone, bauxite, iron ore..
 

 

Why TC Studs roller? 
                  

There are 3 main types of core components of the HPGR:

1. PTA layer roller surface

2. Centrifugal casting composite roller surface

3. Stud roller surface

The disadvantage for first two types is that the roller surface will be subjected to severe impact due to the direct contact of the roller with the material under the action of strong extrusion force (generally 50-300MPa). The abrasive grains and furrows wear, and at the same time, the roller surface will produce squeeze pits. These accumulated pits will cause the fatigue wear of the roller surface material, which seriously affects the normal operation of the equipment.

For stud roller surface, the base body is made of high-strength alloy steel, which has high hardness after quenching and tempering. The wear-resistant layer is made of tungsten-cobalt hard alloy studs and inlaid on the body. Generally up to HRC67 or higher, the hardness is much higher than that of the PTA layer roller surface and the centrifugal casting composite roll surface, and the matrix of the stud roller surface can be well protected by the material lining formed. Tungsten carbide studs roller has a service life more than 6 times longer than that of the surfacing roller surface. 

-Energy saving and environmental protection

-High work efficiency

-Maintenance-free

-Low labor

Why Miller^TM TC Studs?

We understand better than anyone what you need in your equipment and we've worked closely with people just like you to understand and cater to those needs. We've serviced a number of operations worldwide with high capacity High Pressure Grinding Rolls.

Our Advantages:

1. Hemispherical top, protect the studs from being destroyed by stress concentration.

2. Round edges, protect the stubs being damaged during production, transportation, installment and using.

3. HIP sintering ensure good compactness and high toughness for the products.

4. Special technology to eliminate the surface stress after surface grinding, and increase the surface hardness at the same time.

5. Grease used on surface of the products to avoid oxidization.

6. Miller has 660t TPA pressing machines and monthly production of HPGR studs is over 20metric tons.

7. Miller Carbide has accumulated a number of drawings for different designs of studs with hemispherical top, flat top, conical top, round edges etc.
Drawing of tungsten carbide studs can also be provided by Miller, as a professional manufacturer specialized in tungsten carbide studs manufacturing for 11 years, we have professional engineers to make the drawing per customer's requirement.
