YGM series is most economic and suitable to get 325mesh limestone powder.

YGM High-pressure grinding Mill has the same working principle as Raymond Mill, but its grinding fitting is furnished with 1000 – 1500 kg high pressure springs.When the machine works, the grinding rollers, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure ratio is 1.2 times of Raymond mill given an identical condition, and its output may increase 10% to 20%;

Grinding Mill series history .

✬1980s, the first generation of R series Raymond mills.

Used to produce 80-425 mesh powder.

✬1990s, the second generation of YGM series high-pressure Raymond mills.

Used to produce 80-425 mesh powder.

Under the same power, the output is increased by 10%.

✬ 2009, the third generation MFW series European version of the mill.

Can produce 80-600 mesh powder.

With large output and advanced structure, it can meet customers’ demand for fine powder to the greatest extent.

✬2012, micro powder grinding mill HGM series, produce 425-2500 mesh powder.

How to finish install the grinding mill ?

1.It is considered to hang the lifting tools of 1.5-2tons above the main engine when building workshop.Just for easy maintenance.

2.Put the main engine and blower on the reinforced concrete horizontally (YGM6S ,YGM75 ,YGM8SB is not

necessary ) , pour concrete into the feet of whirlwind power and dust collector after installing them.

3.Make the flange between all connecting pipelines sealed with gaskets.

Before starting the grinding mill please make sure check whether there is iron ore in the machine or not, lock

all the observation doors，adjust the position of blower and main spindle open exhaust valve fully. At the same time check whether there is iron ore in the machine or not ,check whether the bolt and nut especially in the main engine is loose.

Starting sequences:start analyzer first,blower second，main engine third.It is a must to put some stones (tiny

stones firstly and then normal ones) when starting main engine.Please open air valve ,gradually turn down exhaust valve under the condition that do not materials spill out of the feed port.And then adjust the the finished product size.

When stopping the machine,first to stop feeding about one minute,and then stop blower,finally anal

Feeding control:Feed uniformly.Trying to get the max capacity according to the load (ammeter) under different feed.Bolts and other irons are forbidden in the machine.
