    Introduction

    The bauxite grinding mill is widely used in crushing, drying and classification. It can be used as a complete set or add on to the crushing plant and also in cement plants. The main purpose of the bauxite grinding mill is to make it easier for you to understand how it works, as well as its advantages and disadvantages.

    The bauxite grinding mill is a highly efficient desulfurization equipment of power plant.

    The bauxite grinding mill is a highly efficient desulfurization equipment of power plant. The bauxite grinding mill is used for grinding bauxite into bauxite powder, and it's also used for desulfurizing coal in power plant.

    The efficiency of the bauxite grinding mill is as high as 97%. It can be used over 10 years without any maintenance, so it's very energy-saving and cost-effective.

    It supplies timely and appropriate treatment of fly ash and slag to the cement.

    It is important to understand that these two types of materials can have a negative impact on the environment and the quality of life.

    One common type of rock mill is the ball mill, which uses centrifugal force to spin a large number of heavy metal balls. When these balls are spun at high speeds, they will grind down whatever material is fed into them. The resulting powder or slurry has been ground down into very small particles that can be used for various purposes. Ball mills are often used in conjunction with other processes such as flotation circuits or magnetic separators.

    It can switch between slag drying and crushing based on the temperature, maximizing energy efficiency.

    It can achieve automatic switching between slag drying and slag crushing by controling the temperature, so as to save energy consumption and consumption of parts. It can be used in cement plant, power station and other many places which need the dry waste or wet waste grinding.

    It can be used to replace a traditional two-stage crusher, becoming what some call an "all in one" machine.

    The bauxite grinding mill is a new generation of equipment which integrates crushing, drying, grinding ,grading and conveying. It can replace the traditional two-stage crusher and become a new generation of equipment which integrates crushing, drying, grinding ,grading and conveying. The higher reliability of the bauxite grinding mill enables it to run in low efficiency range by using special wear-resistant liner plate to ensure smooth operation; meanwhile it has high durability with less damage from foreign objects due to its unique structure design (transition passage structure).

    The bauxite grinding mill can save energy consumption by about 30% compared with other methods at same capacity.

    When the fineness of the finished product and the motor power are same, the output of the jet mill, agitator mill and ball mill is more than double;

    For a given fineness of the finished product, the output of the jet mill, agitator mill and ball mill is more than double. The specific gravity of bauxite ore is 2.6g/cm3, its hardness is 6-7 on Mohs scale. It's not easy to crush hard materials by conventional crushing machine such as jaw crusher or impact crusher because of their large hardness and big resistance force respectively. So when you choose your crushing equipment for processing bauxite ore, ball mill is a good choice because it has high efficiency in grinding soft material like coal (hardness is 5-6), granite (hardness 5) or limestone (hardness 3).

    Jet mill can also be used to process bauxite ore but its capacity is lower than that of ball mill; so if you want higher capacity for your production line then I suggest using both jet mills with agitator mills together rather than one only for crushing purpose.

    When grinding materials such as carborundum, bauxite and quartz sand at high hardness levels, pressure rollers can produce more material than ball mills.

    When used for grinding high hardness materials such as carborundum, bauxite and quartz sand, the pressure roller suspension grinding system has higher production efficiency than ball mill.

    The pressure roller suspension grinding system consists of a drum that rotates in an eccentric way and a pulley with two rollers fixed on its surface. The pulley is driven by the motor to rotate at different speeds according to the requirements of different materials. Because of this rotation, material is thrown off from the drum onto a cyclone collector or bag filter to separate coarse particles from fine ones. After that, it goes back into a cyclone collector through an air channel to remove dusts before being transported back into the barrel again by another air channel (dynamic classifier).

    Under normal circumstances, it uses automatic control system to start up and shut down according to process requirements

    • Under normal circumstances, it uses automatic control system to start up and shut down according to process requirements.
    • The automatic control system is used for controlling the starting and stopping of equipment.

    How does bauxite grinding mill work?

    The bauxite grinding mill is a highly efficient desulfurization equipment of power plant. It supplies timely and appropriate treatment of fly ash and slag to the cement.

    The bauxite grinding mill is composed by two parts: a drying system and a classification system. The drying system consists of a rotary dryer, heating device (electric heater or steam heater), heat-insulating layer (refractory brick wall), hot air conveying ducts and discharge ducts; The classification system has an innerbailer chain classifier with the functions of sorting out particles according to different sizes, separating coarse material from fine material, removing large impurities from raw materials etc.,and a filter press for removing water content in fines; Finally´╝îthe oversize product leaves with its own weight or by air conveyor belt conveyor belt into storage piles or directly into steel making furnace through transport truck hopper preheater heaters feeder pipe connecting manifold land piping superheater cooling tower steam turbine generator winding drum sanding machine blow bar clamping device breaker molding machine rolling machine cooling machine packing machine unloading device vibration absorber control box dust collector control box dust collector discharge hood dust pump exhaust fan explosion-proof cabinet power supply panel control cabinet floor fan safety switch insulation mats
