The Origin of raymond mill In 1891, Konow and Davidson utilized for any patent of raymond mill, which was a cylinder filled with raymond mediums, supported by the products in both ends. The cylinder is rotated from the centre line on the raymond mill. The raymond medium falls down from your particular height through the frictional force. The components by means of the consistent impact and raymond by the raymond medium within the cylinder are for being the certified items. When the raymond medium could be the steel roll, the mill is named the rod mill. The key size from the raymond mill is the diameter and also the length in the cylinder. The ratio between the length as well as diameter in the cylinder is known as the length-diameter ratio. The mill of ratio smaller sized than 2 is definitely the quick mill without the need of any silo, ratio about 3 will be the mid-long mill with 2 silos, ratio bigger than 4 is definitely the long silos with 3 or 4 silos. The Actuality of Domestic raymond mill The ores dressing technologies in our nation is influenced deeply by the former Soviet Union. The primary crushing gear is raymond mill, with only a couple of enterprises making use of rod mill to guard the fragile minerals such as tungsten, tin, antimony and essential. The mainraymond mill in our nation contains the raymond mill, tubular raymond mill, cone raymond mill, chinaware raymond mill, internal, overflow kind and lattice sort raymond mill. The rotating pace mainly ranges from 17 to 28r/min, together with the discharging particle sizes ranging from 0.075 to 0.89mm, the productivity from 0.65 to 100t/h plus the total excess weight from 5.5 to 175t. Various Major Troubles Faced by Domestic raymond mill 1.Large price of raymond mill products. Given that the rotating speed from the raymond mill cylinder is relatively lower (15 to 15r/min), the engine should really be collocated with pricey graduating gadget. 2.Higher value of manufacturing. The raymond medium is abraded when impacting and raymond the elements. Hence, throughout the raymond creating method, the will need of steel boards is huge, with 1 kg per ton raymond. 3.Lower doing work efficiency. While in the course of action of creating the raymond, the electric quantity used for crushing is about 2/3. In accordance to statistics, the electrical power consumption of creating one particular ton raymond will not be decrease than 70 kwh. However the economizing of this part of electric is extremely low. 4.Significant dimension. The fat of big type raymond mill can attain several tons. Future of raymond mill The coming years will be the swiftly building period of raymond mill throughout the world, in particular for Chinese raymond mill. It is important for that domestic mining enterprises to improve the research and update of merchandise and construct the systematic and in depth after-sale services.
