1. 4500-5500
2. Gongyi Longtai specializes in the proction of ball mill balls. The output is not only affected by the ball load, but also related to the ball diameter. A certain ball diameter and a certain proportion of balls with different diameters are required. Generally, the size range of ball diameter in the cylinder is 25-60mm. If there are large diameter balls in the cylinder, its impact force is large, which is beneficial to crushing large coal. However, e to the large gap between balls, small relative surface area and weak extrusion and grinding effect, the output of coal mill and the fineness of pulverized coal are unfavorable. There are too many small diameter steel balls in the cylinder, and the impact force is small, which will rece the output of the coal mill. At the same time, e to the relative increase of the surface area of the steel balls, the wear of the steel balls will increase, and the power consumption of the coal mill will increase
for example, ring the operation of the coal mill, e to wear and tear, the weight and diameter of the steel balls are constantly decreasing, so it is necessary to add new balls regularly to maintain a certain steel ball loading capacity. Generally, the ball with large diameter is added, and the amount of ball supplement should be determined according to the ball wear rate (the wear amount of steel ball per ton of coal) and the coal grinding amount. After the mill has been running for a certain period of time, the number of small diameter steel balls in the cylinder increases. Therefore, it is generally necessary to stop the machine to clean the steel balls after 3000 hours of operation, so as to remove the balls with diameter less than 15mm and broken balls, and make up for new balls at the same time.
3. 304 stainless steel ball is commonly used in planetary ball mill, roller ball mill, stirring ball mill, vibration ball mill and other ball mills to grind and disperse superfine materials<

characteristics of Tianchuang powder stainless steel grinding ball:
1 generally non-magnetic, but after passing through the light ball, it will be magnetic and can be demagnetized, HRC ≤ 26
2 has good anti rust and anti-corrosion properties
3 good sphericity and smooth surface
4 it is suitable for grinding a variety of materials with high cost performance
stainless steel grinding ball specification: diameter Φ 1mm- Φ 30mm (customized for special requirements)
4. According to the calculation of the cost per ton of ore, if you want to choose the steel ball with high price, 6508 stands by 6911
5. The ball mill in power plant usually has various sizes of steel balls, the maximum size is not more than 60mm. The smaller the steel ball is grinded in the coal mill, and the general power plant only purchases 60mm steel ball
the steel balls used in power plants are usually chromium alloy grinding balls, which can be divided into low chromium grinding balls, medium chromium grinding balls and high chromium grinding balls according to the chromium content
grinding ball material: zqcr2, ZQ means cast ball. CR2 is the mass fraction of chromium. Most power plants use zqcr2. But it is recommended to use zqcr10, high chromium grinding ball with high cost performance
the wear of low chromium grinding ball is relatively high, and the consumption is large according to the size of coal mill. Usually, more than 0.2kg steel balls are needed to grind a ton of coal. The wear of high chromium steel ball can be less than 0.06 kg, which is less than that of low chromium steel ball
I hope I can help you.
6. Electrical fire can be prevented in the following ways:
1. Circuit breaker with leakage protection function shall be applied
2
3. Improve the configuration of fire extinguishing equipment
I hope our answers will help you.
7.

bus line: Line 5 → M250, the whole journey is about 23.8km

1. Walk about 140m from Shenzhen North Station to Shenzhen North Station

2. Take line 5, pass 8 stations, reach Ling station

3. Walk about 350m to Park Road West Yixiang station

4. Take M250, pass 12 stations, reach Hengfeng Instrial City Station (also take m370, 395)

5 Walk about 420 meters to Shenye u center
