     T130X Superfine Grinding Mill

    Optimized, Accurate, Reliable, Efficient

    T130X Superfine Grinding Mill evolves from TGM Super Pressure Trapezium Mill which has got many patents. Optimized T130X Superfine Grinding Mill adopts classifier with high density impeller, and this classifier can improve the capacity and output sizes of final products.
    Applications: Cement, coal, power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.



    The machine is mainly used in processing powder of mineral materials of metallurgy, building materials, chemical industry, mining, etc. It can grind non-flammable and non-explosive materials with moisture less than 6% such as Feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, iron ore, copper ore, phosphate rock, iron oxide red, slag, slag, activated carbon, dolomite, granite, iron oxide yellow, bean cake, chemical fertilizer, compound fertilizer, fly ash, bituminous coal, coke, lignite, Ling U.S. sand, gold, red mud, clay, Kaolin, coke, coal gangue, porcelain clay, kyanite, fluorspar, bentonite, muddy green rock, leaf wax rock, shale, purple rock, Diego rock, basalt, gypsum, graphite, insulation material, etc.

    T130X superfine grinding mill with innovative design is a new-type grinding machine evolving from the original patented product - TGM Super Pressure Trapezium Mill based on market research, feedbacks and suggestions of customers both at home and abroad. It's optimized on the foundation of TGM Super Pressure Trapezium Mill in function and structure, coming into being its own unique characteristics:

    1, The main frame and the base are completely soft-linked rather than rigid-contacted. It avoids the vibration from the chamber transferring to the main frame and the classifier,which improving the precision of the classifier.
    2, The base are made of anti-crack nodular cast iron which boasts the strength of cast steel,the anti-vibration of cast iron and good impact resistance.
    3, It adopts the reducer that simulates German Flender. Technological advantage of professional reducer manufacturers are made full use of to improve machine stability.Reducer and motor are connected by V-belt which is conducive to overload protection.
    4, The main frame and reducer are connected by pin coupling with elastic sleeve to ward off the breaking of nylon pin ,which improves the reliability of the whole equipment.
    5, The classifier adopts high density impeller which can improve the fineness and capacity. Practice shows that in the case of constant speed, increasing the density of leaves can increase the fineness of the finished product.In other words,in the condition of same fineness, the high-density impeller rotates slower than the low-density one,which reduces the air resistance and increases production meanwhile.
    6, The classifier adopts frequency control of motor speed with the characteristics of energy-saving, precision, good process control mobility and high degree of automation.
    7, Bypass powder collector with a dust isolation chamber make more dust go into the bottom of cyclone by the bypass system to avoid the dust escaping from air vents. Compared with general powder collector,it has the character of low pressure loss and high efficiency, particularly being conducive to collect the powder particles which is difficult to collect.
    8, Same resistance arrangement avoids difference in power from two powder collector, which increases the efficiency,capacity and decreases internal circulation.
    9, The discharges of the collector and dust remover are in the same line which is convenient for powder collecting and packing and reduces the amount of work.
    10, The maintenance platform makes maintenance work safer and more convenient.


    Working Principle


    Large materials are crushed by jaw crusher into required size for mainframe, then the crushed materials are elevated to the hopper by bucket elevator,then to the grinding chamber for grinding by vibrating feeder evenly and continuously. The powder goes upwards with the airflow, after separating by the classifier, those which can meet the fineness requirement enters into the collector through pipes for separating and collecting, and discharged from the discharged valve as finished products. The airflow is sucked into blower through wind recycling pipe at the upper part of cyclone power collector. And the closed airflow circulation system with negative pressure ensures the environmental health of production line site.
