The ultrafine vertical mill in the production line is low productivity and high maintenance cost, so the final production benefit will be In addition, the quality of the finished product produced by this equipment is likely to be unqualified, so it is difficult to put the finished product into the market, so it is difficult for customers to pay back for their investment, so it is difficult for manufacturers to have "repeat customers" and will not get longterm development;In summary, if the ultrafine vertical mill manufacturers want to carry forward, they must ensure the quality of the equipment, ensure that the performance of the ultra-fine grinding equipment is fully utilized, and then provide a comprehensive service under the condition of a quality friend chain, quality + The two-pronged approach of service can better reflect the value of customers, and it is also conducive to the better development of manufacturers.
