Today, I will share 5 aspects about choosing grinding rod.
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 . Coupled with round undischarged
shipped its internal stress, broken rods as explosion - fried, which began from
the principle steel production of steel bars is like blowing balloon must stress
inside to lift off to prevent broken rods.
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. Once a rod bent, the entire order will lead to parallel inside
the bar mill is disrupted (the bar is run in parallel inside the mill, the
material into which time slot is ground into small particles or powder), light
leading to the bar after the low-order mill efficiency, while leading to the bar
mill was thrown, threatening the security of staff and damage to the mill and
other production equipment.
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.
For example, a variety of steel bar diameter ratio between irrational,
unreasonable loadings, the additional steel bars unreasonable, not timely
removed the bar and so fail.
