The vertical mill option has been slower to enter the cement grinding market. Grinding bed stability problems offered a challenge which the major manufacturers battled with, until finally a significant number of mills began to be installed in the late 1990s, and this has multiplied in the past decade.
06/03/2009#0183;#32;cement mill motor high temp. Hey; Due to a problem in our cement mill motor cooling system, temperature of the winding temperature increased to the high limit (120 C), solving the problem of the cooling system will take few days but till that time we don''t want to keep the mill stop.
05/10/2020#0183;#32;The essentials of electrical systems in cement plants (on photo: Low voltage motor control centres type ''Sivacon S8''; credit: ) Before we dive into details, note that this article assumes that you are already familiar with the basic terms of cement plant equipment and process.
The standard inching drive motor is a NEMA or IEC frame typically foot mounted to a motor scoop or base plate. Typical motor speeds are either 4 or 6 pole, 1750 rpm or 1170 rpm for 60 Hz applications and 1450 rpm or 970 rpm for 50 Hz applications. The advantage of using a four pole motor allows for a smaller footprint and a smaller brake if
Performance. The mill is designed to handle a total ball charge of t at loading with a percentage filling of % in both the chambers. Both the chambers of the cement mill were charged with 80% of the designed charge, which works out to 86 t in Ist chamber and 172 t in the IInd chamber.
Customer: Cement plant From an African cement plant Menzel received the order to supply a interchangeable motor to the existing main mill drive. In fact the customer bought already another interchangeable Menzel motor; he confided these complex tasks to the Menzel specialists.
