[Flotation]: i.e. flotation froth flotation beneficiation methods is to divide dressing surface thereof depending on the physical and chemical properties of minerals. Flotation is one of the most important methods of mineral processing. About 90% of all non-ferrous metal ore flotation process. Suitable copper ore, lead ore and zinc ore, gold, silver ore, molybdenite, Sulfur, phosphorus ore, nickel ore, cobalt ore, graphite ore, bauxite, etc. [Magnetic Separation Method]: Magnetic separation is a beneficiation method that performs sorting in the magnetic field of a magnetic separator by utilizing the difference in magnetic properties of various minerals. Magnetic separation is widely used in the selection of ferrous metal ore, the selection of colored and rare metal ore, and the recovery of medium in heavy medium dressing. For iron ore, manganese ore, rare earth ore, vanadium-titanium magnetite, chrome ore. [Gravity ore dressing method]: Gravity beneficiation (referred to as re-election) is based on the difference in density (commonly called specific gravity) of various minerals, and thus the difference in gravity, fluid dynamics and other mechanical forces in the moving medium, thereby achieving density. The process of sorting ore particles. It applies to gold, lead, tungsten ore, tin ore, iron ore, niobium-tantalum ore, ilmenite and so on. [Chemical beneficiation]: Chemical beneficiation is the use of different minerals in the chemical differences, the use of chemical treatment or chemical treatment combined with physical beneficiation, so that the useful components are enriched and purified, and ultimately produce chemical concentrates or Separate product (metal or metal compound). Applicable to vanadium ore, copper oxide ore, alumina zinc ore, high carbon molybdenum ore, nickel oxide ore. Non-woven special equipment accessories
Non-woven fabric is a new type of modern material. It has a wide range of uses and can play more roles in clothing, agriculture and industry. The production of non-woven fabrics is also mostly mechanized, which makes it possible to produce a large number of non-woven fabrics in batches. Non-woven fabric winders are one of its equipment.
Non-woven fabric, also called non-woven fabric, is composed of oriented or random fibers. The production of non-woven fabrics often uses polypropylene pellets as raw materials, and is produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. In the production of non-woven fabrics, the raw materials need to be spun and formed and then processed. In the web-forming work, a non-woven web forming machine needs to be used. The web forming machine uses wind in the drafting duct to process the silk. After drafting, a machine for non-directional weaving into a net is carried out. However, polypropylene pellets are prone to broken filaments and stiff blocks during drawing, drafting, and web formation. Therefore, in order to improve the quality of the finished non-woven fabric, it is necessary to clean the formed non-woven fabric. When dealing with broken wires and stiff blocks in traditional web forming machines, workers usually use brushes or scouring pads behind the web forming machines to clean up. Because the belt width of the web forming machines is relatively long, and the conveyor belt speed is relatively high at the same time. Fast, the cleaning range that workers can cover is limited, resulting in low cleaning efficiency, which in turn affects the quality of the finished non-woven fabric.
The slitting machine is mainly used to cut large-format non-woven fabrics into multiple small non-woven fabrics of different widths for processing non-woven products. The equipment adopts DC speed regulation, feeding constant tension control, air knife slitting, rewinding pressure and other devices. The rewinding tightness after slitting is adjustable, and the slitting end surface is flat. The equipment is of high quality and beautiful appearance. It is the ideal equipment for the slitting of large non-woven fabrics. In addition, according to the needs of users, the equipment can also add a dummy cutting function, that is, the original fabric is dummy cut and then slit and rewinded.
Non-woven fabric machinery is a general term for the production of non-woven fabric products, and adopts an overall modular design with a compact and reasonable structure. The control part adopts advanced PLC microcomputer control, and the international famous brand frequency converter speed regulation.
