vertical roller Mill processing of coal gangue and broad prospects

Coal associated waste rock. Solid waste in tunneling, mining and coal washing process in the discharge. Is carbon, muddy and sandy shale mixture, with low calorific value. Carbon containing 20% ~ 30% some containing humic acid. In recent years China has been the accumulation of coal gangue is about 1000Mt, and the annual continued to discharge about 100Mt, not only the accumulation of land, but also pollute the air or fire caused by spontaneous combustion. Coal gangue is mainly used in the production of building materials cement, lightweight aggregate concrete, bricks and so on, also can be used for the recovery of coal, power generation co firing of coal and gangue, preparation of the crystallization of aluminum chloride, water glass and other chemical products and extraction of precious metals, but also can be used as fertilizer.
After the use of coal gangue powder
vertical roller mill processing equipment is very wide, can be used for the production of low calorific value gas, production of ceramic production, soil improvement agent, or used for paving, I***a Atsu, ground filling reclamation. The spontaneous combustion of coal gangue in the can and afforestation, beautification of the environment.
Machine limited company in Shanghai is a professional production of powder machine, vertical roller milling machine, vertical roller mill equipment, high efficiency and energy saving, vertical roller mill equipment of the production of environmentally friendly cleaning, and applications in all walks of life are widely, if there is demand for processing coal gangue can be customer, provide you with the most complete services, and the best the after sale service.
There are coal gangue is a kind of mining solid waste, is a mixture of coal washing plant washing gangue, coal production in the coal gangue, hand selected out from the coal and rock and coal gangue piled together semi coal and rock roadway in the white waste etc.. Coal vertical roller mill can not only coal gangue turning waste into treasure, but also to promote environmental protection, land saving, energy saving and emission reduction and industrial upgrading and other advantages, is the new darling of the market. After the coal gangue after vertical roller milling machine for processing, can be applied to concrete, aerated brick and other building materials, both to reduce the pollution of the environment, and can create value, is the focus of the application.
Powder processing equipment powder in recent years has undergone a great change, which has been in use from Raymond vertical roller mill equipment to the current development of high-pressure powder vertical roller mill, straight through the new powder equipment, powder vertical roller mill, three ring micro powder equipment, powder equipment products from the work and market fit have a more significant increase. To improve a variety of new powder equipment technology, open a broad market prospect for the application of market ore powder, powder industry has the potential to break the shackles, become immeasurably in modern industrial life. If you want to consult more on coal waste stone powder machine equipment problems.
