Ore sampling method and sampling specifications (1)

Sampling, processing, and laboratory work are important means to guide prospecting exploration and determine the industrial value of the deposit. The purpose is to determine the content of useful components and harmful impurities in ore by the analysis of samples, to define the boundary between ore

Laser processing reasonable operating parameters

1. Laser drilling size and its precision control (1) Control of aperture size Using a laser with a small divergence angle (0.001 to 0.003 rad), the focal length can be shortened or the output energy can be reduced to obtain a small aperture. For high melting point. The material with

Microwave drying equipment market share a long way to go

The microwave dryer is different from the traditional drying method in that the heat conduction direction is the same as the moisture diffusion direction. Compared with the traditional drying method, it has the advantages of large drying rate, energy saving, high production efficiency, uniform dry
