Nutshell filter using high-quality pecan shells as raw material, after crushing, polishing, steam cleaning, drug preservative treatment, the two screening processed. This filter tough, wear, compression (anti-pressure 23.4kgf), chemical stability, strong pollutant adsorption (adsorption rate of 27-50%), anti-oil, easy backwashing and regeneration, backwashing low intensity (6.7L / Sm2), filtration rate (24-26m / h), do not harden, does not rot, and never replaced, every year you can just add 5-10%. Oil removal rate of 95%, oil drops 5mg / g or less. Applicable to oil fields, saving and environmental protection equipment. I plant using advanced foreign technology, technology, professional production of vitrified grinding wheel porosity pore material - walnut shell particles. The products and conventional pore material - refined naphthalene, compared with uniform pores, odorless, non-polluting, easy to use, inexpensive, non-destructive use of employees' health but also safe. Moreover, the wheel pore size can be arbitrarily selected. Therefore, in the abrasives industry 60 years abroad, it has been widely adopted.
