Ore screening by excavator
I'm from Jining. I wanted to give up the big excavator last year. My friend recommended Jinwang's small excavator. Jinwang did a good job here. The main reason is that at that time, I thought the price and service were OK, and the people at hand said it was OK to drive it. Don't worry, we Jining people are really, ha ha ha, look at this picture. It's the same. No, I bought this one. Hope to adopt ~ welcome to ask, the landlord still don't know, private letter I also line

Fluorite, also known as fluorite, is a kind of mineral, also known as soft crystal, colorful gem, rainbow gem, dream stone, etc. Its main component is CaF2, which contains more impurities. Fluorite in nature often shows bright colors, and its hardness is lower than that of a knife. It can be used as gemstone and night pearl, but most radioactive materials are usually harmful to human body
I suggest you try this:
- first of all, the quartz ore you choose does not contain iron or contains very little
- secondly, in the mining process, in addition to large excavators (generally these machines have little pollution to the ore, which can be ignored), the electric crusher, sanding machine, pulverizer, screening machine, etc. you should avoid the direct collision between the materials and the machinery, and the wear-resistant non-ferrous materials should be selected for the parts of the machinery in contact with the materials, including from the crushing and grinding of the feed to the screening. In this way, qualified quartz sand procts can be proced. At present, we have developed a complete set of such proction line < / OL >
the advantages of this method are: simple structure, large output, no pickling and no pollution
precautions:
large drill with bit shape must be used to go deep,
directional blasting can also be carried out if it is very hard and thick.
