Home / How Air Clutch Engage Cement Mill
The technical characteristics of large cement mill developed and designed by CITIC HIC plant are as follows The transmission forms adopted by the drum mill are edge transmission center transmission multi point meshing edge transmission etc the driving forms are asynchronous motor + reducer + pinion + girth gear and synchronous motor + air clutch + pinion + girth gear.
The ball mill is traditionally the basic system used for the grinding of raw material clinker and additives in a cement plant as well as a wide range of minerals Benefiting from a large experience the FCB B Mill has been designed to be particularly well adapted for the grinding of products at high fineness and grinding of very abrasive.

The Cement Mill No 3 building behind the old 6 cement silos Works’ own Block Plant (BP) had two almost new concrete block making machines The mill drive shaft had to be as short as possible and had a hydraulic clutch of a new design too The middle of the three 8m bays was left free and had no roof enabling an access to the mill.
For new cement plants our process expertise and product portfolio deliver plants with the minimum environmental footprint And what is good for the environment can also be good for profitability as energy efficiency coincides with minimising the cost of fuel and power.
These clutches use a single plate friction surface to engage the input and output members of the clutch This style of clutch is used in applications ranging from copy machines to conveyor drives They are the most common type of electromechanical clutches Other applications for these clutches could include packaging machinery printing machinery food processing [ ].
Portland cement is a generic term for nearly all modern cement It owes both name and origin to a British stone mason named Joseph Aspdin In the 1820s Aspdin’s quest for a manufactured counterpart to natural or Roman cement (derived from volcanic ash and other naturally occurring minerals) led to his discovery and patent of portland cement.
Grinding in small plants as in larger installations has proven to be the most costly of all unit operations from both capital and operating standpoints Therefore grinding deserves the most scrutiny of all operations during the design procedure A recent survey by a major grinding mill manufacturer reveals that than 80 autogenous or semi autogenous mills having between 100 and 1 000.
For instance a 90 V clutch a 48 V clutch and a 24 V clutch all powered with their respective voltages and constant current would each produce the same amount of torque.
Conventional mill drive system such as ring gear pinion gearbox coupling or air clutch motor shaft and motor bearings Eliminating such components significantly increases the efficiency and the availability of the mill The gearless motor is fed by a cyclo converter which lets the operator easily vary the mill’s operating speed.
Ball mill is the most widely used kind of grinding equipment Zenith Ball mills are widely used in various types of ores' benefication electricity cement and chemical industries With high comminution ratio it can carry out dry or wet pulverizing and can meet demand for sustainable large scale production.
The picture below shows the link of the two threaded shafts and the feed shaft with a cable pulley When building anything with hydraulics it’s important to understand the pressures created The ratios and gpm on my mill work very nicely The mill can travel full speed in six seconds and then raise 36 in about the same time frame.
The clutch disc and pressure plate may have a larger diameter to spread the load across a larger surface area The linings on the clutch disc may be a higher temperature wear resistant friction material The diaphragm spring or coil springs in the pressure plate may be stiffer so the clutch can hold heavier loads without slipping.
B Drives Economics at the time of plant design and mill purchase determine the drive to be used The simplest drive is the low speed synchronous motor with speeds in the range of 150 to 250 RPM connected to the mill pinion shaft by either an air clutch or flexible coupling.
Ball Mill DESCRIPTION PARAMETERS Application Mineral Processing Material Iron Ore etc Max effective capacity 570 cubic meters Max shell diameter 8 m Max shell length 12000 mm Max shell turning speed 15 r min Max charge ratio of media 38~40 Max feed media 1005 tons.
Mill Pinion Gears Our high torque high precision integral and non integral mill pinions are used in SAG horizontal ball mill and rotary kiln applications across the globe Supplied as an individual component or as a fully optimised system comprising a girth gear mill drive gearbox pinion and barring drive our pinions are manufactured.
Around the center axis The mill is driven by a girth gear bolted to the shell of the vessel and a pinion shaft moved by a prime mover The prime movers are usually synchronous motors equipped with an air clutch or gear transmission After the mill is charged with the starting material (ore rock etc ) and the grinding media (balls).
Jan 01 2012 Cement raw cement production line is the preparation process control of a link had the whole system of an independent control unit Fig 1 The control system structure of roller mill Design proposal followed Considering of real time and safety requirements the system uses the AC800F Field Controller S800 series I O control module.
Prominer provides ball mill rod mill grinding system which is widely used in various types of ores' beneficiation electricity cement and chemical industries It can carry out dry or wet pulverizing and can meet demand for sustainable large scale production.
High Production Hydraulic Portable Sawmill with Accuset2 Controls Vertical Side Supports and Chain Log Turner Loaded with high production features including advanced hydraulic log handling Accuset2 Setworks auto board return arm with outfeed table and faster sawhead movement the LT50 hydraulic portable sawmill is engineered for speed and high production.
• Clutch shaft rpm • Maximum air pressure available Clutch Control Normal mill starting procedure is to bring the motor up to operating speed and then engage the clutch to accelerate the mill Airflex offers a simple but reliable system for clutch control The system consists of two parts the pneu matic and electrical portions.
