The patent register and technology innovation Ultra-fine coal Grindding mill  

1. Brief introduction of  Ultra-fine coal Grindding mill

        Absorbing the advantages of manufacturing companies home and abroad, VTM series Ultra-fine Grinder is our company’s patent research products in 2005 after so many investigation, study and test. It is a new-type ultra-fine processing machine of high efficiency and low cost. It is the achievement of advanced technology and the new replacement of traditional mill.

        VTM series Ultra-fine coal grinding mill is one type equipment process fine or Ultra-fine, It is main suitable to not flammable not explosive brittle material which middle,low hardness, or moh’s hardness ≤7 degree ,such as the materials calcite, chalk, limestone, dolomite, kaolin, bentonite, speckstone, mica, magnesite, illite, pyrauxite, vermiculite, sepiolite, attapulgite, rectorite, kieselguhr, barite, gesso, alunite, graphite, cann, phosphate ore, potassium, float stone and hundreds of other materials.

2. Our Product  Ultra-fine coal Grinding mill advantages

*1>Efficient, save investment :Under the circumstance that both finished product fine degree and electromotor are same, It exceed jet mill,vertical grinder,,ball mill,ring roll mill one –fold output, compare with large-scale complete equipment,save investment 60%, reduse consume around 30%.

*2> Easy damage part has long working life, mill roller ,mill loop adopt special material forged, thus make use extent enhance greatly. Under the circumstance that both finished product fine degree and materials, It’s easy damage part has two/three-fold working life than impact crusher, turbine crusher , when process calcium carbonate,calcite, working life can reach 6-8 years.

*3>Good safety reliability,fixing ,maintaining easy:coal grinding mill Main engine foundation adopt whole cast structure, absorb shudder performance is good, It’s stabl and reliable while working, reduce foundation building cost and shorten building time limit for a project. Bearing site seal and reliable. So there have no problem that destroy machine because of bearing or steal parts easy damaged. Mill roller could be cross out of the machine by hydraulic pressure, change bush board and large mil machine overhaul space, overhaul task very convenience.

*4> Good products fine degree ,large than surface area: products fine degree once could reach d50≤2.6μm;d97≤10μm;Could produce Ultra-fine powder disposable/one-off than surface area 22400cm2/g(d97=10μm)

*5> High run efficiency: principal axis adopt speed cut engine run, energy consume is low, efficiency, efficiency ≥96%.

*6> Using protect environment impulse duster and muffler can lighten dust pollute, reduce noise, reach state protect environment standard, non-pollution to surrounding environment.

*7> Mill roller with motive power itself, mill roller and mill loop grind differential.
