Lining - what is it?

Surely many have heard the word "lining." What it is? This is the name of the internal protective finish of thermal machines and their parts (mills, furnaces, ladles, pipes, furnaces, hogs, etc.), pickling baths, chemical apparatuses and much more.

Mill Mill Protector

The lining for drum mills used to be made of steel, but recently it has become apparent that rubber is much better. This material has many advantages.

Rubber lining demonstrates excellent performance. This concerns primarily ball mills, namely, aggregates of the third and second grinding stages. But that is not all. A rubber lining is also excellent for refining mills. This is the best option for them. For ball aggregates of the first grinding stage, it is recommended to use a mixed rubber-metal lining, which is very resistant to abrasion and corrosion. She serves a really long time. The lining of mills is a serious matter, and we need to approach it responsibly.

Lining device

In rubber protective linings, the most popular is the “plate-elevator” scheme. Together with it, plates for lining the wave profile, consisting of one element, are used. The strength of the protective lining and the performance of the unit largely depend on the parameters of the interior decoration - the thickness of the plates, as well as the profile and length of the lifters. By the way, they depend on the size of the drum, the torsion speed of the mill, the processing medium, the characteristics and size of the material.

To prevent the discharge grill from clogging, the effect of elastic shear in its design should not be neglected.

When choosing the configuration of the optimal protective lining, it is necessary to pay attention to the technical features of the mill (torsion speed, size of grinding media, load level, etc.). Everyone who works with the mill should know not only the meaning of the word “lining”, but also basic information about it.

Why is rubber better than metal?

Rubber has many unique qualities: it is not susceptible to corrosion, has a good ability to cushion, and also excellent anti-friction performance. Based on this, it can be argued that this material surpasses metal in almost all respects. What other benefits does rubber have?

  • It remains in excellent condition for a long time, which means it can serve for a long time. Rubber protective lining can be used 1.5-2.5 times longer than metal. That's how good such a lining is. What is it, many people working in the factory know.
  • Such a lining is very easy to assemble and disassemble. This means that the unit availability factor is high. 3-4 times less time is spent on assembling and dismantling the rubber protective lining. Impressive, isn't it? The duration of repairs and inspections is also reduced.
  • The rubber lining vibrates and makes less noise, and this is very important. The noise level is reduced by 2-3 times. Of course, it is much easier for workers to fulfill their duties under such conditions.

Bucket lining

Lining of buckets is the main method that significantly increases their resource. In most cases, it is simply necessary.

ladle lining
Protective lining is applied to the external and internal parts of the attachment in order to protect it from heat. This is primarily about the ladles used to pour steel. The lining also protects the equipment from mechanical damage. This is especially necessary for buckets of bulldozers and excavators.

Immediately after applying the protective cladding to the attachment, it becomes clear how effective it is. This is especially noticeable on the example of buckets of machines working with stones.

Economic necessity

From an economic point of view, all attachments must be coated with protective linings. After all, not only does the lining help to increase the life of the bucket, it also allows you to significantly reduce the time spent on repair work. What does it mean? It turns out that the lining indirectly affects, among other things, an increase in the duration of continuous operation. She really has a lot of advantages. Every bucket needs a good lining. What it is is known to everyone who works with attachments.

What material is suitable for bucket lining?

It is very important to choose the most suitable lining material, which will be durable and strong. It is precisely on its durability that the reliability of the protective lining itself and the durability of the bucket will depend. It is important to keep this in mind.

Optimal options for bucket lining include CDP boards. They are very durable and reliable. In addition, they have the following advantages:

  • simple and quick fastening;
  • choice of plates of different sizes;
  • simplicity of their rolling;
  • the opportunity to purchase them in our country, which is much faster and more profitable than an order from abroad.

Here are how many advantages a quality lining has. What is this, some, unfortunately, it becomes known quite late.
