How to choose the ore crusher? What should we pay attention to?
2, after determining the specifications of the crusher model should be compared with several manufacturers, it is best to choose a company with strong reputation, so if there are quality problems in the future, you can be guaranteed. As for how to choose, it is best to be able to inspect it on site, or to refer to the production line that the crushing manufacturer has previously done for customers, to see how it works, and how is the word of mouth among users?
3. Consider the specific gravity of the ore: The specific gravity of the ore is directly proportional to the productivity of the crusher – the same crusher will have different productivity when dealing with ore with different specific gravity.
4. Consider the humidity of the material: the humidity of the material itself has little effect on the crushing. However, when the amount of impurities (mud amount or fine ore) in the material is too much, the fine material will agglomerate or stick to the coarse particles due to the increase of humidity. On the material, which increases the viscosity of the material, reduces the rate of discharge, and reduces productivity.
5. Consider the particle size composition of the crushed material: when the content of coarse particles (large dry discharge port size) in the crushed material is high or the ratio of the maximum mass of the ore to the ore width is large, the crusher needs to achieve a large crushing ratio. Therefore, the productivity is reduced; when the content of the fine material of the crushed material (close to or smaller than the size of the discharge port) is large or the ratio of the maximum mass of the ore to the width of the ore is small, the crushing ratio to be achieved is small, so the productivity is high. improve.
6, the total production and grading requirements of the finished product, according to the choice of crusher type and production capacity; material physical properties, such as friability, viscosity, moisture content and maximum feed size; technical and economic indicators, do To meet the requirements of quality and quantity, easy to operate, reliable work, and maximum cost savings; crushing equipment is a big investment, customers must be careful when choosing.
7. After-sales service is guaranteed: At the same time, it is important that the after-sales service of the manufacturer is also a problem that users should consider when purchasing. Many merchants use after-sales service as a highlight of the new competition. After-sales service is a very important one. Problems, in many cases, professional manufacturers can provide rapid maintenance capabilities, and the failure of mechanical equipment has little impact on production schedule.
