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.

Q: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump: Buffing should be better, to see how your embryo, but a bit difficult

Q: What are the casting parts used to test shrinkage holes?: 2. x ray. This method can do nondestructive testing, but the cost is higher. Generally, high castings are required.

Q: What's the effect of casting copper?: Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.

Q: What are the requirements for casting steel castings?: 2, the plane should be placed on the following.3, thin parts should be placed below.

Q: What is the difference between forging parts and casting parts?: The casting parts are low in cost and short in production period. Because the molten iron has good flow properties, complex shapes can be formed. But because there may be sand holes, pores, shrinkage holes and other defects, the quality is unstable, easy to produce many defects, mechanical properties are not forged well, thus affecting the service life.

Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.: The technical condition or the material column in the title column will tell whether it is a casting drawing or not. However, the need for casting drawings, and some also through machining (car, milling, etc.), this should be part of the process drawings, process drawings are described

Q: What should I pay attention to when designing a casting structure?: (2) in the prevention of metal mold casting misrun and cold partition should pay attention to the following problems: the structure of A casting thickness should be appropriate not too thin, especially when casting size when not too thin; the B should avoid a big level, because it makes the liquid metal in the casting. Rise slowly, and the air contact surface, easy oxidation, and because the metal type liquid metal heat quickly, quickly lose liquidity, easy to cause misrun and cold lap, slag and other defects; C casting shape should be streamlined to avoid sharp corners and has sharp change connection structure in order to facilitate the flow of liquid metal. 2 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.

Q: Does anyone know how to make precise casting parts for aerospace or manufacturers of single and small quantities of automotive parts and components, mainly in Beijing, Tianjin and Tangshan?: List of China's military enterprises list of ten major military groupsChina Nuclear Industry Construction Group CorporationChina Aerospace Science and Technology CorporationChina Aerospace Science and Engineering CorporationChina Aviation Industry CorporationChina Aviation Industry Corporation IiChina State Shipbuilding CorporationcsicChina North Industries Group CorporationChina South Industries Group CorporationChina National Nuclear CorporationKey military enterprisesShipbuilding industry:China State Shipbuilding Corporation (South ship group), (China Shipping Group)China Shipbuilding Industry Corp (North Ship group), (China Shipbuilding Industry)Guangzhou Shipyard International Limited by Share Ltd (GSI)Jiangnan Heavy Industry Limited by Share Ltd (Jiangnan Heavy Industry)Nuclear industry:China National Nuclear Corporation (CNNC)China Nuclear Industry Construction Group Corporation

Q: What are the causes of pitting on the surface of a precision casting?: The quality of the shell surface is out of order. Or shot blasting out of question.

Q: As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.: Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
