Packing :
Outer packing is plywood case , which is up to the international standards.
Inner packing is moisture-proof and water-proof membrane.
All of package are wrapped by 0.55mm steel belt to further strengthen .
Advantages: We use a new type of special power generator to produce multivariate and high frequency vibration to screen samples with high efficiency; standard sieve, to ensure the accuracy of sample analysis; electronic delay device, to set equivalent screening time among the same material to ensure the uniformity of the sample analysis and reduce the experimental error to the minimum, and then to make an accurate judgment of the quality of the product.
