Using the advanced "liquid nano formula • normal temperature and high frequency curing" glue making process, the wear index of wear-resistant rubber plate has reached 128%, the rebound has reached 80%, the tensile strength has reached 23.5mp, and the tear strength has reached 168N / mm.

In addition, the high manganese steel lining plate is prone to creep, extension and surface transformation, which will cause reverse bow deformation and can not achieve ideal work hardening. Now the…

Ball mill is a beneficiation equipment for regrinding the cement raw material milling after crushing operation in the mine concentrator.

In addition to the concentrator, it can also be used for grinding cement, silicon hydrochloric acid products, new building materials, refractory materials and glass ceramic materials. The cement raw material milling liner is one of its main accessories.

Let's…

In the cylinder, the materials are crushed due to the throwing impact and self grinding of the steel ball and the ore itself. Due to the continuous feeding of materials, the pressure causes the materials in the cylinder to move from the feeding end to the discharge end, and the materials reaching the particle size of finished products are discharged from the discharge end of the cylinder.

During wet and dry conical lattice…

The no-load commissioning of the barite ore grinding plant means idling without loading steel balls and ore materials. Generally, the idling time shall not be less than four hours. Normally, it needs to operate for 8-16 hours.

The lubrication of each lubrication point is normal and there is no oil leakage.

The temperature of the main bearing of the mill shall not exceed 50 ℃.

The mill…

After the barite ore grinding plant is installed, it is necessary to conduct a trial run to check whether the barite ore grinding plant is installed correctly.

However, before the trial run, it is necessary to fully check whether the inlet cover and feeding and discharging device on the cylinder are firm, sealed, and whether the lubrication system is unblocked without oil leakage, oil leakage, etc…

The high underflow concentration may be caused by the feed slurry concentration or the underflow opening is too small. You can add an appropriate amount of water to the feed first. If the underflow concentration is still large, you need to replace the larger underflow opening.

The "fine underflow clamp" may be caused by the underflow orifice wear, the underflow orifice is too large, the overflow pipe diameter is too small, the pressure is too high or too low, it is necessary to adjust…

In order to prevent clogging, facilities for preventing coarse materials and debris (such as chip removal screens) can be installed in the feed tank of the LUM ultrafine vertical mill group.

At the same time, the feed tank should be emptied in time when the machine is stopped, so as not to cause problems when driving again. Because of precipitation and high concentration, it can cause…

In production, two-stage classification or improved classification equipment can be used To Improve Classification Efficiency and vertical roller mill grinding efficiency accordingly.

In the grinding process, there are many factors affecting the grinding efficiency of vertical roller mill. Many factors can only be analyzed and judged qualitatively, and it is difficult to make quantitative…

High classification efficiency means that the qualified particle size can be discharged timely and efficiently, while low classification efficiency means that most qualified particle size products cannot be discharged and returned to vertical roller mill for regrinding, which is easy to cause over grinding.

In production, two-stage classification or improved classification equipment can be used To…

Reasonable addition of steel balls in the long-term operation process, the mutual grinding between the steel balls and ore of ore milling plant will cause a certain degree of wear of the steel balls, resulting in the change of the proportion of steel balls of different sizes, resulting in the change of the fineness of grinding products, and then affect the grinding efficiency of ore milling plant.

Therefore, the operators of ore milling…

After long-term operation, ore milling plant will encounter the problem of grinding efficiency decline more or less, which not only affects the normal operation of the whole concentrator, but also damages the economic benefits of the mine owner.

Then, in production practice, how can we effectively improve ore milling plant grinding efficiency? We can start from the following seven aspects.

Enhancing the grindability of raw ore…

Chemical bleaching: impurities in calcite can be oxidized into soluble substances by bleaching, and then washed and removed to improve the whiteness of calcite grinder milling plant machines.

However, the cost of chemical bleaching is relatively high, which is usually used for calcite concentrate that needs further purification after impurity removal.

Roasting purification: magnetization roasting,…

Silica sand is a common clay mineral in nature. Silica sand is a useful mineral for making white pigments. Whiteness is the main performance parameter affecting the value of silica sand. The silica sand grinding mill often contains harmful impurities such as iron, organic matter and dark substances.

These harmful impurities will make the silica sand show different colors and affect its whiteness.…

It should be noted that when the grinding products are required to be coarse, the variation of ultrafine vertical mill productivity with feed particle size is obvious, while when the grinding products are required to be fine, the variation of mill productivity with feed particle size is not very prominent.

When the feeding particle size, i.e. the grinding particle size, is small, the…

If the local temperature is high or the working environment temperature of ultrafine vertical mill is high, the bearing temperature will also rise. Therefore, we need to pay attention to the requirements of crusher for working environment.

There are many reasons for the heating problemrolling bearing of ultrafine vertical mill. When dealing with the heating problem of ultrafine vertical mill…

The poor installation quality is mainly reflected in the non levelness of the bearing seat, the misalignment of the coupling and the lack of sufficient thermal expansion of the bearing.

The two rolling bearing of vertical roller mill are generally installed with one end fixed and one end free, so that when the temperature rises during operation, the shaft can swim freely without blocking after thermal…
