High chromium ball manufacturers choose reference suggestions:
1. There must be nationally recognized testing centers and laboratories, such as direct-reading spectrometers (for the inspection of molten iron to ensure that no molten iron components are qualified), Rockwell hardness testers (special inspection equipment for spot-checking product hardness, etc.), etc. Professional testing equipment;
2, must have advanced production equipment and heat treatment equipment, such as automatic oil quenching equipment and automatic tempering furnace equipment, high chromium ball oil quenching can truly reflect its superiority, so that product hardness to achieve higher standards;
A qualified high-chromium ball manufacturer must, like the Ningguo Steel Ball Industry Guide to open-source wear-resistance, achieve industry-leading levels in production equipment and technology research to ensure the production of high-quality, high-chromium balls.
The use of shoddy high-chromium balls:
1. Appearance is poor: appearance of steel ball has serious appearance defects such as slag inclusion, sand inclusion, high pile, wrinkle skin, etc. These defects are the stress concentration point of steel ball and will cause steel ball to change due to stress during the use of ball mill. Broken or flaking, etc.
2, high wear: The main reason is that some manufacturers do not have quenching equipment, steel balls without quenching equipment, poor wear resistance, or shoddy, resulting in low product hardness, resulting in high wear;
3, crushing: mainly due to the composition of the ball is not up to standard, without heat treatment or just a simple heat treatment, or the use of inferior raw materials, resulting in high inclusions in the ball, causing broken;
4, peeling: the reason is similar to the broken.
The use of bad high-chromium balls on the use of the manufacturer's hazards:
1. Although the purchase cost is low, the actual use cost is high;
2, due to the ball broken, spalling, will cause direct economic losses to the enterprise;
3. Due to the use of inferior high-chromium balls with low wear resistance, the ball ratio of the ball mill will be unstable during the operation, so that the grinding efficiency of the ball mill will be reduced, which will directly lead to a 3% decrease in the output of the ball mill. %;
4. The use of inferior high-chromium balls will also reduce the fineness of grinding ore, reduce the recovery rate of concentrates, and reduce product quality.
To sum up, the use of inferior high-chromium ball will bring incalculable losses to the enterprise. In order to ensure the normal operation of the ball mill and improve the efficiency of the ball mill, to achieve a real cost-saving enterprises, experts recommend that a company should choose a comprehensive strength Well, companies with guaranteed production equipment, testing equipment, and craftsmanship levels, and high chromium ball prices are reasonable. The "Guyang" brand high-chromium ball produced by Ningguo Open-source Abrasion Co., Ltd. has high hardness, good wear resistance, small hardness difference between the ball surface and the center of the ball, stable performance, extremely low crushing rate, and almost no out-of-round deformation. High, worthy of customer trust and choice.
Manufacturers choose high chromium ball reference suggestions
For manufacturers of ball mills such as mines and cement plants, choosing a qualified high-chromium ball manufacturer can effectively improve the production efficiency of ball mills, ensure product quality, and save company costs.
