Hi Vernon. Thank you for your question.

Now, limestone grinding mill is more and more popular in recent years. It may be due to the market demand, but it also comes from its high quality.

The first reason is good environmental protection condition.

The entire grinding process of limestone grinding equipment is carried out in confined space. The biggest difference with the traditional Raymond machine is that the negative pressure vacuum production rather than positive air pressure supply production, thus effectively eliminating the dust caused by the process of grinding.

The second reason is reliable stability and efficient production performance.

The production technology of limestone grinding equipment is mature. In the production process, the failure rate is low, and the equipment running rate can reach more than 98%, and the production efficiency is high.

The third reason is low labor cost.

Limestone grinding equipment is highly efficient and requires less operating personnel, resulting in relatively low labor costs. The grinding capacity of limestone grinding equipment reaches 16-20 t/h, which is equivalent to the production capacity of 10 4R3216 pendulum mills. At the same time, the limestone grinding equipment has a high degree of automation. All the control is carried out on the distribution control panel. A limestone grinding equipment can be operated by two people. In addition, the limestone grinding equipment has high reliability, good stability, small maintenance. And it does not need a lot of operators to maintain.

The fourth reason is low energy consumption.

Limestone grinding equipment takes advantages of high reliability and good stability, which directly reduces the amount of maintenance, thus reducing the cost of maintenance. Under normal production conditions, the most direct maintenance cost of limestone grinding equipment is the replacement and maintenance of abrasive parts such as grinding rolls and discs. However, when the roll sleeve is worn to a certain extent, it can also be used repeatedly to lengthen the service life of roll sleeve. When the wear of the roller sleeve reaches limit, the output of the mill decreases greatly and the operation condition of mill is bad. The mill should stop and replace the new roller sleeve lining plate. Usually, a set of grinding rolls and liners can be used for about 1800-2300 hours, and the total amount of grinding powder can be borne for 45,000 tons. The effect is quite obvious.
