In this technical article electrical systems in cement plant will be touched upon. All machines are driven by electric motors. Majority of the motors are 400- 440 volts. A selected few motors of higher ratings are MV motors with 3300, or 6600 or 11000 volts. Most motors are fixed speed and unidirectional motors.
Ash Grove's previous, unreliable motor control system required constant maintenance. Challenge. At Ash Grove, motors power everything from the massive, revolving, rock-filled kiln to the grinding of up to 4,500 tons of cement per day. Demand is rising, increasing the need to keep the plant – and thus, its motors – up and running.
One operator faced top-up cement in the annulus between the 9 5/8- and 13 3/8-in. casing strings in an offshore gas well and could not cut and pull casing as planned. Weatherford deployed the Endura dual-string section mill and safely exposed a 98-ft section of formation.

The poles of the gearless or synchronous motor (also called wrap-around motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.
Henan ZK Corp produced cement ball mill has 31 models with diameter from 2.2m to 4.2m. The matching motor is 380KW to 3530KW. A single cement ball mill can meet the grinding of 11-87t cement products per hour. If combined with roller press, the production capacity will be increased greatly.

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, i.e. 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

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Rebar is central to reinforced concrete, so a basic understanding helps. The various sizes are important to know: a #3 bar is 3/8" in diameter, a #7 bar is 7/8" in diameter, etc. The easy rule of thumb for rebar sizes is to take the rebar size and divide by 8 for the diameter in inches. Rebar. Diameter.
