We are the top 3 manufactures for cast grinding ball in terms of tureover in china.

High Chrome Grinding Media Balls normally be used as grinding media in ball mill for grinding clinker,mineral process.

 

For coarse compartment and without roller machine,balls between 90 and 60 are used.

For Find grinding compartment ,balls between 50-15 are normally used ,or  combined with grinding cylpebs are used.

If the ball mill has roller machine ,due to the feed size is smaller ,the ball charge could smaller(40-70 for first chamber,40-10mm for fine compartment)

In normal feed size of clinker,the wear rate less than 30gram/tonne,the breakage rate less than 0.5%


Our Grinding Ball Production Line:

1.Sand Lined Iron Mold Casting Line,which is Applicable For Chromium Grinding Balls With Diameter 40 To 150mm,Average Production Capability 2 Tonne Per Hour Per Set.


2.Flaskless Molding Casting Line:Suitable For Batch Production Of Casting Balls With Diameter 10 To 40mm,Casting Cylpeds Dimension Range From 6*6mm To 40*45mm,And Even Small Castings.

Q:How to cast iron and wrought iron collocation
2, listen: Pig beating sound boring, wrought iron beating sound loud.
Q:What are the requirements for casting steel castings?
4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface
Q:What is the difference between forging parts and casting parts?
Forging is in hot state through the metal hammer or press equipment produced by forging parts. A casting is a metal that is liquid and is poured into a cavity of a specified shape and cooled and solidified. It is the forging metal soft pinch molding, and casting the metal into thin cooling solidification.Forged parts are costly and have long production cycles.
Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
For the nodular cast iron, the hardness, strength and wear resistance are improved, such as used in the manufacture of automobile, tractor, diesel engine crankshaft, connecting rod and other important parts. A normalizing and hypereutectoid ball annealing before, can eliminate the mesh two cementite spheroidizing annealing, to ensure that all spheres of cementite. Annealing is a metal heat treatment process, which means the metal is slowly heated to a certain temperature, sufficient for a long time, and then cooled at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust microstructure and eliminate tissue defects. Its purpose: (1) reduce hardness and improve machinability; (2) eliminate residual stress, stabilize size, reduce deformation and crack tendency; (3) refine grain, adjust microstructure and eliminate tissue defects. In production, annealing process is widely used.
Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?
Proofing refers to making the first sample to confirm to the customer
Q:The cause of fracture and why there is no toughness
This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?
The choice of shot blasting machine, this is according to the workpiece size, yield, whether can collision, and the working time and other factors considered, while the price of different blasting machine are not the same, but the vast majority of small castings used crawler shot blasting machine, according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation
Q:What kind of flaw detector is better for casting parts?
If you want to detect internal defects, you can use ultrasonic flaw detector, ray flaw detector can also, but the ray of the safety protection level is too high, not recommended priorityMacro Xu flaw detector answered, such as the magnetic particle inspection machine has the demand can contact us, Baidu "macro Xu flaw detection""
Q:How about casting parts for a year?
There are various casting stresses after casting, which can be divided into two kinds: thermal stress and shrinkage stress. In a long time placed in the atmosphere, called aging treatment.Aging treatment is an effective measure to eliminate casting stress. Aging is divided into natural aging, thermal aging and resonance aging.1, the so-called natural aging, the casting is placed in the open field for more than half a year, so that the internal stress relief.
Q:What method of casting does not rust? I think the sample is like oil
Close to the solder, and slowly dissolve is hot melt double-sided adhesive, otherwise it is oily double-sided adhesive.
