Today I will share how to select grinding rods for you.
1. High wear. Round steel owing to low hardness, toughness was poor,
resulting in consumption is very large, and indirectly led to the magnetic part
of the task is heavy, costly, and even affect the quality of products.
2. Two tapered. The bar two tinny are many reasons, mainly because the two
ends of the bar and rod mill material contact area and the chances are greater
than the middle part, resulting in two effective grinding time longer than the
middle, once two and significant differences in the proportion of the middle of
the naked eye can see the emergence of this steel rod we call "failure" because
it has not achieve an effective role in the grinding mill inside.
3. Broken rods. The reason is loose inside the material. Steel billet
problem, only the large steel mills to reach inside tight technical
requirements, especially the diameter of 70mm or more, although most of the
steel billet to complete the form, but the compression ratio and low
hardenability, that is not organized strictly .
4. The rod bending. Bending rod is mainly due to the low hardness round,
quite soft, when the mill was affected by external force such as impact, bending
easily occurs.
5. Low productivity, mainly the qualified products. It is a problem that a
lot of companies, many reasons, the wear resistant metal rod its a great
impact.
