subject: Some Problems That Raymond Mill May Has [print this page] Some problems that Raymond mill may has Some problems that Raymond mill may has
With unceasing progress of mill technical level, the fineness material can reach becomes smaller and smaller, and the corresponding application field becomes more and more widely. At the same time, as the promotion of health consciousness, people ask for more in market building decoration materials and decorative supplies, for example: paint, pigment, fly ash, cement, calcium carbonate powder, artificial stone, barite, whose processing are closely linked with ball mill; but defects like low efficiency, large energy consumption, large dust of ball mill has gradually become a huge resistance for industry development -- in this case, mill machinery products with high performance and low pollution become the urgent needs of milling industry.Classification and characteristics:
Most of the ordinary cement mill equipment is used in circuit grinding system, which is characterized by high efficiency, large output, power consumption-saving, especially in the grinding of slag cement, its performance is more prominent.
(2) High yield and high fineness cement mill:
It is mainly used in open circuit grinding system, which is characterized by simple system equipment, simple technological process, small investment and less area of factory building covers.
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
