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 improve the surface roughness of casting parts?
One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.
Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
According to the requirements of the workpiece annealing, there are many kinds of annealing process specifications, such as full annealing, spheroidizing annealing and stress relieving annealing. Steel the steel quenching is heated to the critical temperature Ac3 (hyposteel) or Ac1 (hypereutectoid steel) above a certain temperature, holding time, so that all or part of 1 Austenitic, then the cooling rate is greater than the critical cooling rate of fast cooling to below Ms (or near Ms isothermal) of martensite the body (or bainite transformation) heat treatment process. Aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials are usually treated by solid solution or heat treatment with rapid cooling process. Tempering is a heat treatment process where the workpiece is hardened and heated to a temperature below AC1, which remains cool for a certain period of time and then cools to room temperature. Tempering generally followed by quenching, the purpose is: (a) to eliminate the residual stress caused by quenching, prevent deformation and cracking; (b) hardness, strength, plasticity and toughness of workpiece is adjusted, to use performance requirements; (c) the size of organization and stability, ensure the accuracy improvement; (D) and to improve the processing performance. Tempering is therefore the last important step in obtaining the desired properties of the workpiece. According to the tempering temperature range, tempering can be divided into low temperature tempering, medium temperature tempering and high temperature tempering. This answer is recommended by the questioner
Q:What are the requirements for casting steel castings?
1, high quality requirements of the surface or the main processing surface should be placed below.
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'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:Which surface is coarser for cast iron or cast steel castings? Why?
The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron.
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.
Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
The material is usually steel material price plus the cost (per ton of 2.5-3 million, plus profit).In the Yangtze River Delta region, generally 304 casting price of about 5-5.5 million / ton.The price will be higher if the parts are complex, or a piece weighs less than 100 grams.
Q:Where is the precision casting factory?
Shandong, DongyingThe birthplace of precision casting
Q:When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!
Problem one,1, according to drawings, castings, material requirements and machine power, choose the right diameter of roughing tools, and can process this material blade type.2, according to the actual size of the casting blank, calculate the number and path of the knife, pay attention to small cutting depth, large feed, cutting width, to ensure that the tool diameter 80 - 90%, the amount of not full knife cutting, this tool and machine tool damage.Question two,If they can not change the casting blank allowance under the condition that the quantity large diameter cutter, such as milling cutter main angle 7560 degrees can give reasonable processing parameters, the same cutting depth should not be too large, because in the same machine power, tool diameter increases, cutting depth will need smaller.
