European ladder mill

product description:

     European ladder mill with the international advanced level of technology, with a number of independent patent technology property rights of the latest grinding equipment --MTW Series European ladder mill, is our expert on the basis of long-term research and development experience on the mill, according to 9518 bit mill users and the proposed use, after painstaking research of the latest innovative design mill, the model uses the overall drive bevel gear, internal lubrication system, curved duct latest patents , mainly used in mining, building materials, chemicals, metallurgy, thermal power and coal industries grinding Mohs hardness of 9 or less, humidity various non-explosive mineral materials, finished product fineness of 6% or less in 30 -400 mesh arbitrary regulation.

working principle:

     Large bulk material by jaw crusher to the desired particle size, the material will be sent by the hoist storage hopper, and then vibrating feeder evenly quantitative material will continuously fed into the host mill indoor grinding, grinding after powder will air rising wind machine, the separator was classified in line with the fineness of the powder with the air through pipes into a large cyclone collector, collected separated by a powder discharge valve is finished powder. Airflow created by the whirlwind powder collector upper return duct suction centrifugal fan, native entire airflow system is closed loop, and is in a state of negative pressure circulating. In the grinding room was grinding material because there is a certain moisture content, grinding mill when generating heat causes evaporation chamber gases changed the air flow, as well as the whole of each pipe joints Mifengbuyan, outside air is sucked, so that air circulation flow increases, to do to achieve balance by adjusting the exhaust gas stream between the host and the fan, and the excess gas is introduced into the bag filter, the powder will bring the residual gas collected after discharged residual gas is purified.


     1, the overall drive bevel gear: the traditional mill needs another gear, by coupling the drive shaft, the installation of the difficulty, easy to produce noise, reduce efficiency, MTW Series European ladder mill for the overall drive bevel gear, the structure is more compact, more convenient installation adjustment, efficiency is greatly increased.
     2, the internal lubrication system: the traditional mill in the form of lubricating grease lubrication, resistance, temperature rise, short bearing life, MTW Series European ladder mill with internal pump, without an additional oil pump or lubrication station, you can achieve a spindle bevel gear shaft bearings and bearing lubrication.
     3, curved duct: the traditional mill in Mill duct are bar-type duct. This structure exists duct board air impact generated resistance, large molecules collide with each other between the air flow energy loss, easy to produce eddy currents duct blockage and other shortcomings, MTW Series European ladder mill employed a curved duct-type air duct, tangential import smooth airflow, resistance, internal export orientation is conducive to spread the material, blocking material is not easy.
     4, curved blade interchangeable blade: the traditional mill blade edge wear faster, the overall blade blade after blade wear section, we need to replace the whole blade, material waste, increasing down replacement. MTW Series European ladder mill blade, the blade made of high wear-resistant alloy materials, long life, simply replace the replacement blade part, improve material utilization. Further conventional planar blade, after scooping up the material deposited on one level, so that the central roller grinding ring wear serious, surface type blade material can be oriented facade, so that the ring roller mill, middle and lower part of the can grinding to uniform wear, but also increases the effective working area, thereby increasing the yield.
     5, isolated cyclone powder collector: The isolation structure between the inner cylinder and the powder mixture stream, can effectively improve the efficiency of the separator and classifier accuracy.
     6, without resistance into the wind volute (small observation door without vortex): a traditional mill into the wind volute observe the door sector board protruding outward facing, with air intake volute surface is not a plane, so it is easy to produce vortex effect, increasing energy consumption. MTW Series European ladder mill with internal door and the inner surface of the inner surface of the inlet volute on the same surface, so that we can effectively prevent the vortex effect.
     7, attractive appearance: the European version of the mill not only uses a lot of advanced internal structure, but also used the appearance of a beautiful arc structure design, so that the entire machine is even more beautiful and intelligent..
