An oxide is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2 atom. Metal oxides thus typically contain an anion of oxygen nitrous oxide zinc oxide magnesium oxide iron oxide aluminum oxide cerium oxide red oxide copper oxide lead oxide calcium oxide graphene oxide scandium oxide ethylene oxide nickel oxide propylene oxide molybdenum oxid tin oxide silver oxide Origins: iron,germany,india,australia

Ball mill for lead oxide is a basic device in the modern world of metallurgy and is extensively used in a variety of applications. Among others, it's applications in the processing of non-ferrous metals is one of the most important. In the field of lead processing, dry type ball mills are used for conversion of lead pellets into fine lead oxide powder (lead oxide free lead), also commonly called grey oxide due to its appearance. The ball mill with its preparatory and collecting equipments is therefore also called a grey oxide plant. Description of process: Lead is melt in a melting pot and cast into pellets (hemispherical or cylindrical shape) at a ball making machine and fed into the ball mill. The ball mill is rotated on its own axis at low speeds. The rotation of the mill imparts tumbling & cascading action to the balls fed (in this case the lead pellets). The rotation is adjusted so that the raw material inside does not reach critical speed. Below the critical speed (at around 65 - 75%), the balls which are carried along the walls of the mill fall back to the center. This continuous action leads to friction and generation of heat which induces the reaction of lead (pb) with oxygen (o2) present in air and generation of lead oxide (2pbo). This reaction is an exothermic reaction which leads to generation of heat and this sets of a chain reaction of heat generation and accelerated oxidation process. Draft of air through the mill carries small sized or light particles outside the mill to the collection system. Temperature within the mill is controlled with the help of water spray outside the barrel of the mill. Several crucial characteristics of this produce such as free lead percentage, retention percentage, apparent density are set as per requirements of the client.

ZXL-001- nano TiO2 photocatalyst anatase detailed desc ription: Nano TiO2 anatase is a kind of white powder product. It has a strong photocatalytic oxidation-reduction capacity, high chemical stability, non-toxic, forbidden band gap of 3.0 eV, being UV (under 380 nm) excited scope. In the effect of sunlight or ultraviolet light , the electronic (e-) on the valence band can be excited transition to the conduction band and brought a corresponding hole (h +) on the valence band. And then h + e- and H2O adsorbed on the surface of TiO2 play a role and generate • OH, • O2-high active Group, active oxygen and hydroxyl radical with high oxidation which can make harmful organics, pollutants odor, bacteria etc. such as formaldehyde, aminomethane, benzene, xylene,ammonia, organic TVOC, and so on oxidative decompose into harmless CO2 and H2O. Giving full expression to the nano TiO2 photocatalyst for antibacterial, sterilization, disinfection, remove pollutants, hydrophilic, and the self-cleaning properties, it is an ideal environmental protection products. Product standards: Appearance: white powder TiO2 content: í¦ 90% Crystal: anatase SEM average size: í_ 20 nm PH value: acidic Photocatalytic efficiency: í¦ 60% Moisture: í_ 1% Product Performance: It is a white powder-like object, under the influence of the visible or ultraviolet light it has a strong ability to oxidation and reduction, stable chemical properties, making formaldehyde, methylamine, toluene, xylene, and other harmful organics, pollutants, odors, bacteria, viruses, microorganisms and other harmful organisms completely decompose into harmless CO2 and H2O, and having the specialities such as removal of pollutants, hydrophilic, and self-cleaning properties, lasting performance and no secondary pollution.
