Some Points to be Noticed during the Grinding Process

The crushing degree of various materials is different, either is the granularity, so if hard materials and soft materials are put into the ball mill together, the clay with small granularity will form a thin mud cover on the surface of the raw feldspar and quartz, which could decrease the grinding ability of grinding medium, lead to the over grinding of soft materials, and extend the grinding time.

During the grinding process, the materials that are hard to be crushed should be fed first to shorten the grinding time and improve the grinding efficiency.

In abroad, some people will grind the hard materials and soft materials separately, and then mix the slurry according to the requirements.

But this process also has its shortcomings, and the mixture of raw materials could be uneven

According to the scale of production and conditions of usage, there are a variety of different models of ball mills.

As for the ceramic industry, due to the special nature of the production process, ball mill is always a wise choice because of its single structure, easy maintenance, flexible terms, etc.

Ball mill is widely used in the ceramic industry, but it may be unstable in the process of using a ball mill, which will have a great influence on the process control and product quality.

The grinding operations are mostly done in cylinders with grinding medium.

The continuous rotation of cylinders brings the grinding medium to a certain height, then falling down because of gravity.

In this way, the impact strength is produced.

At the same time, due to the grinding media revolution and rotation along the cylinder axis of the cylinder body, the squeezing and grinding force generated in contact with the cylinder interval between the grinding media, so that the ore milled.

The grinding job with water is called wet grinding, and the dry grinding doesn’t need to feed water.

The grinding operations use harder and larger proportion of forged steel (or steel) manufactured into balls and long stick, sometimes using gravel ground softer ore.
