Mining machinery manufacturing industry is the establishment of an independent state based industrial system, to measure a country's industrial strength is an important symbol.The following are some difficlut problems in using mining machinery equipment:
Why is it difficult for flotation separator to separate the colour fine materialReasons are as below:
1. With large surface area, surface energy dramatically increases. On one hand, under certain conditions, different minerals are easily non-selective condensed on the surface. On the other hand, due to the surface energy of fine grain, although the machine has a high adsorption power to stuffs, the selective adsorption is poor, which makes difficulties for selecting fine material.
2. Small fine material is barely possible to collide with bubbles. When collide with bubbles, it is not easy for fine material with light weight to overcome the resistance of hydrated sheath between the mineral particles and air bubbles and to attach on the bubbles.
Many sand making enterprises are hard to make money for the frequent damage of sand maker, which not only increase the cost but also result in downtime. Henan Hongxing will bring you know the reasons.
First, sand maker can not be started and operated when it has materials, because it will burn out the motor for the high starting pressure and lead to other damages. So we must pay attention to the operation order. First start the crusher, and then join the raw materials.
Second, any crusher has its own proper scope, it is the same as sand maker. The raw material size can not exceed a certain size. Too much ores will plug the feed head of sand maker, which will less cause the cleaning of sand maker, more lead the broken of impeller and even cease production.
The impeller is an important part of the dryer machine, and also is the most vulnerable part. Because the materials is distributed in the impeller, it is very easy to make the wear for the improper operation. So we should operate the machine with extra care to avoid the accidents and reduce unnecessary economic losses.
