In 1891, Konow and Davidson applied for your patent of sand making machine, which was a cylinder crammed with grinding mediums, supported with the units in both equally ends. The cylinder is rotated through the centre line from the cement mill. The grinding medium falls down within the specified top by the frictional pressure. The materials by means of the continuous effect and grinding with the grinding medium within the cylinder are to get the capable products and solutions.

Once the grinding medium could be the steel roll, the mill is termed the rod mill. The key measurement of the Raymond mill will be the diameter plus the length in the cylinder. The ratio among the length as well as the diameter on the cylinder is called the length-diameter ratio. The mill of ratio more compact than two may be the shorter mill without any silo, ratio all-around three would be the mid-long mill with 2 silos, ratio larger than 4 may be the extended silos with 3 or 4 silos.

The Actuality of Domestic Raymond mill

The ores dressing technology in our country is influenced deeply from the former Soviet Union. The primary crushing equipment is Raymond mill, with only a few enterprises using rod mill to protect the fragile minerals such as tungsten, tin, antimony and key.

The leading Raymond mill in our country includes the cement Raymond mill, tubular Raymond mill, cone Raymond mill, chinaware Raymond mill, internal, overflow type and lattice type Raymond mill. The rotating speed mainly ranges from 17 to 28r/min, with the discharging particle sizes ranging from 0.075 to 0.89mm, the productivity from 0.65 to 100t/h and also the total weight from 5.5 to 175t.
