Mica Crusher Nigeria

Nigeria is the leading producer of muscovite mica followed by Brazil. Other producing countries are the USA, Tanzania, Rhodesia and Argentina. The USA generally produces scrap mica. The leading producers of phlogopite mica are Malagasy Republic and Tanzania whose average annual productions are 1,000 tonnes and 300 tonnes respectively. Small production of phologopite is reported from Canada, Tanzania and Nigeria.

Mica is invaluable in the electrical industry because of its unique combination of physical, chemical and thermal properties, low power loss factor, dielectric constant and dielectric strength. Dieletric strength is the ability to withstand high voltage without puncturing.

Mica Basics

According to mica crushing demand dressing process, with the corresponding feeder, vibrating screen and the cone crusher, and the European version Jaw Crusher complete crushing and screening system formed, fully meet the needs of mica mineral in the process. SBM has many years experience in mineral processing equipment, in order to satisfy different users mica fineness, yield, use requirements and different technical requirements, in line with local conditions, to optimize the investment scale, the economic benefits of investment to get the best for the purpose of the mica mineral projects, the company may send the user site engineering and technical personnel to conduct site surveys, planning, design process, and is responsible for the later installation and maintenance services.

Mica is a kind of rock-forming minerals, usually six or diamond was fake plates, sheets, columnar crystal. Color changes with different chemical composition, mainly with the increase of Fe content and becomes deeper. Mica is characterized by the insulation, high temperature resistant, shiny, physical and chemical properties of stability, good insulation, elasticity and toughness. Most used in industry is muscovite, followed by phlogopite. They are widely used in building material industry, the fire industry, and fire extinguishing agents, welding, plastics, electrical insulation, paper, bitumen paper, rubber, pearlescent pigments and other chemical industries.

Industry is mainly the direct use of natural mica crystals processed into products they need. The larger crystal, no defects, the higher its economic value, and therefore mica ore beneficiation process as possible to protect the natural mica crystals from destruction.

Mica flotation ore beneficiation processes are two processes of selection and wind. European version of SBM jaw crusher, dedicated to hard, abrasive materials, strong fragmentation, the European version Jaw Crusher main chassis parts, eccentric shafts rotating part of the work of some of the crushing chamber, insurance, installation, adjustment devices nesting population parts. European version Jaw Crusher motor-driven belt and pulley, through the eccentric shaft to move the European version Jaw Crusher swing up and down before and after, when the dynamic European version Jaw Crusher to promote the dynamic jaw motion to the fixed jaw, the material was crushed broken or split. When the movable jaw and fixed jaw plate in the eccentric shaft, under the action of spring back when crushed or split previously been broken jaw plate material from the bottom of row discharge port.

The Mica Industrial Applications

Sheet mica is used in a number of electrical and electronic appliances in different shapes and sizes. As an insulating material it is used in equipment like condensers, transformers, sheostats, radio and electronic tubes and radar circuits. It is used in the form of washers, discs, tubes and plates.

Nowadays mica is finding increasing use in equipment that encounters very high temperatures like rockets, missiles and jet engine ignition system. Phlogopite is used in spark plugs. Sheet mica, however, is not always available in required size as demanded by the industry.

Great progress has been achieved in making built-up mica called micanite. Mica films are placed with alternate layers of binding materials like shellac, alkyl, or silicon resin and then pressed and baked. Micanite is in common use now. It is convenient to cut or punch micanite according to requirements.
