Raymond mill is also called Raymond milling machine, English full name is: Raymond mill.
It is used for all kinds of ore powder production, braize production, such as fine powder processing of the row ore, Gypsum mine and coal. It looks like a erect steel container from the appearance, with air intake, air outlet and feed port in the middle part. The grinding machine with the electric motor drive, internal grinding stick and millstone rotate the material and blow the finished materials by the wind from the air outlet. Upside of the internal machine, there is a separator, which can separate the thick powder and then collect them by means of the wind from the air outlet.
Raymond milling machine is called raymond mill for short, it is a very important grinding equipment and come from outside the country, now in China has developed. What’s the common stoppage that is caused in the process of using the Raymond mill? And how to solve them?
The first common stoppage of the Raymond mill: no powder or less powder with low output.
The reason: (1)The lock is not adjusted well, Seal lax and make the powder pour.
(2)big wear of the shovel knife, material can't afford to shovel.
Removal Methods: (1) Check and adjust the seal lock (2) change the shovel knife for a new one.
The second common stoppage of the Raymond mill: Finished product powder is too thick, or too thin.
Reason: (1) blades of the grader wear serious, it can't work for classification. (2)volume of fan air is not appropriate
Removal Methods: (1) change the blade and turn down the volume of the air from air intake
so as to solve the problem of thick powder
(2) enhance the volume of the air from air intake so as to solve the problem of thin powder
The third common stoppage of the Raymond mill: the host mill’s current and the temperature is raising, and the fan’s current decline.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,dryer machine, symons cone crusher Welcome all of you to visit our official website.density separators: http://www.china-hxjq.com/n259.html
Reason: The feeding is excessive, duct is jammed, pipe exhaust is not free, cycle airstream fever which makes high temperature of the machine and lord of the current, but fan current decline
Removal Methods: (1) reduce the inlet amount, clear away of the powder in the air duct
(2) open the ductwork valve wide, control the temperature of the materials below 6 ?
The forth common stoppage of the Raymond mill: high noise and vibration of the host machine.
Reason: (1) The feed into the machine is small and the shovel knife badly worn, which can't afford to shovel the material, also the anchor bolts are loose.
(2)material is hard and impacts machine strongly.
(3)The grinder roll and ring lost its round shape and is out of shape seriously.
Removal Methods:(1) Adjust the feed of the Raymond mill and replace a new shovel knife
(2) Replace feeding particle size (3) Replace The grinder roll and ring
The fifth common stoppage of the Raymond mill: the vibration of the fan.
Reason:(1) the leaves of the fan accumulated powder or wear imbalance (2) Anchor bolt is loose.
Removal Methods:(1) Remove the accumulated powder or replace the blade (2) Tighten the anchor bolts
The sixth common stoppage of the Raymond mill: Rotating device and the oil tank of the grader fever
Reason: (1) the oil has large viscosity and thick , Screw pump oil cannot added up and make the Upper bearing lack of oil.
Removal Methods:(1) Check if the oil grades and viscosity is as expected (2) check the running direction of the grader
The seventh common stoppage of the Raymond mill: the damage of the into powder bearing with the grinding roller device.
Reason: (1) lack of the oil or the damage of sealing ring (2)Long-term lack of maintenance and cleaning
Removal Methods: (1)adding oil according to the stipulated time (2) cleaning at regular intervals, and replace the oil seal
