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: 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: How do casting parts remove stress?
Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
Q: Is the cast steel a casting part?
Cast steel is one of the casting parts that you call. The material is made of carbon steel or alloy steel, stainless steel, etc. the method is cast
Q: What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
Corundum sand: the main mineral composition is corundum alpha -Al2O3, used for investment casting, ceramic mold casting shell materials. The olivine sand: the main mineral composition of olivine (MgFe) 2SiO4, used in cast iron, non-ferrous alloy castings and high manganese steel casting molding sand and the core sand. Silica resources in nature resources, but suitable for casting with high SiO2 content of natural silica sand is not too much. Since 1951, China has carried out a general survey of the casting sand resources in the territory, but mainly limited to the main traffic lines and major industrial cities. Survey results show that Chinese can be used for natural silica sand casting is very rich in resources, a wide range of distribution. Inner Mongolia Zhelimumeng, natural silica sand reserves amounted to hundreds of millions of tons, the particle shape close to the circular, the content of SiO2 is about 90%. Fujian, Jinjiang Dongshan sea sand, the content of SiO2 is 94 to 98%, with a low volume of mud, are good natural silica sand. Are Duchang, Yongxiu Jiangxi County Xingzi, a large number of Quaternary lacustrine deposition of silica sand, the content of SiO2 is about 90%, low iron content, alkaline oxide less, uniform size, is a good lake sand. Guangzhou, Hunan and other places have abundant easily broken weathered sandstone, processing artificial silica sand, the content of SiO2 in more than 96%, can be used for the production of steel castings. Jiangsu Nanjing red sand, sandy mud pure, moderate, strong permeability, good viscosity, high silica content, less water, fine particles, pulls out the casting is smooth, stable quality, can be made of cast iron and non-ferrous metal parts of the sand and core sand
Q: What's the density of the cast iron? The density is thin and the density is thin
Generally cast iron thick place, density is empty, thin place density a little more.
Q: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
Q: My parts complex, machining costs are relatively high, so want to cast, but the surface needs anodizing, what material will be better?
The common material that can be anodized is aluminum alloy. It is recommended to use casting aluminum alloys, such as ZL102 and ZL105, which are commonly used as cast aluminium alloys. The processing of aluminum casting is easy. After processing, the surface of the whole part can be anodized. The color can be chosen.
Q: What are the general technical requirements for casting parts?
No matter what kind of material casting, there are the following major requirements:Material requirements. Mainly hardness, tensile strength, elongation, impact toughness.Two, dimensional accuracy and shape accuracy. Different castings have different requirements. Different sizes and geometric tolerances and different tolerances are adopted.Three, according to the use requirements, the casting of other defects, acceptance requirements. Such as holes, sand holes, shrinkage, slag, sand, crack.........Four. Requirements for defect repair.
Q: Can the casting part be phosphating with the phosphating solution of the pickling board?
If it is Phosphating for painting, it is not necessary, because the surface of the casting is rough and can be firmly bonded with the paint film.
Q: In the design of casting steps and precautions, for casting design, we have what experience?.
A: in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.
