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:Shandong foundry, casting small pieces of precision casting
- Dongying Huayang precision casting factory, the smallest to do 2G pieces.
- 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:For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified
- According to the grade of the parts, according to the relevant standards, the regular drawings will be noted in the technical requirements of the parts.
- Q:The difference between cement sand castings, resin sand castings and vacuum casting parts
- Our country or international, in all casting production in 60 ~ 70% by sand casting is produced, of which about 70% is used in the production of clay sand. The main reason is that the cost of sand casting is low compared with other casting method, simple production process and short production cycle. So as the car engine cylinder body the cylinder head, crankshaft castings are produced using clay wet sand molding process. When the wet type can not meet the requirement to consider the use of clay sand table dry sand, dry sand mold or other sand.
- Q:What are the casting parts processing engineering?
- At present, casting processing, according to metal classification, divided into cast iron, cast steel, casting non-ferrous metal.
- Q:Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
- Annealing is needed to eliminate stress and refine grain
- Q:Heat treatment process and purpose of casting parts
- Natural aging (also known as Chang Hua): lost in the open, the sun and rain, can have experienced years of wind and frost.
- Q:the parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?
- There are several casesThe first hole with a diameter of less than 4MM is generally not done, or as a hole location only for a period of less than 10MM.Second for the big hole, some of the reasons for the holding force, we must increase the slope, direct tapping is unlikely, so it still needs post-processingThird for products with high tightness requirements, some cores need to be made even if they are very small, so they can be tapped directlyFourth, some due to technical requirements, regardless of the size of each other's requirements must be made, there is no wayThe above methods are common, and they will encounter many small problems in actual production.
- Q:After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.
- Not processed, do not understand your problem... There's something wrong with the drilling machine. Please call me
