Description &Application of Laboratory pulverizer for mining Laboratory Laboratory pulverizer for mining is a small lab grinding machine for grinding the ore/material samples into powder, which has been widely used in the laboratory of the geology, mining, metallurgy, coal, power, chemistry and building industries, for the none pollution sample testing. The Laboratory pulverizer for mining gets an automatic dust proof and a pot anti-loose device, which provide the machine advantages of low noise, no dust, and easy operation. The machine adapt high frequency vibrating grinding method to make the power fine and event, no need screening and shrinking, prevent sample mixing. This machine gets a simple structure, nice outlook , small volume, with a high efficiency, the output material is fine and evenly, which could meet the demand of education and research department. no need install and adjusting. Could be used in any location, it s one of the best sampling machines for laboratory use.
