Ball mill control -Automatic start-up control In most cement plants, start up of a mill is conducted through a series of manual operations on the part of an operator. The operator switches on the mill, starts the mill feed and , after ascertaining that the mill load becomes stable , changes the control mode to the constant-value feedback control . Not only the need to watch the process all

suit all mill OEM''s. Key benefits. Cement grinding. The feed for a cement grinding unit will normally be dry and. needs to be ground to a high degree of fineness. To achieve this efficiently, most mills will be split into two chambers. The first is set up for coarse grinding with a target to grind the feed materials down to around 1 mm. We

The cement rotary kiln. When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln.

Kinetics of cement: Degree of hydration or Degree of. For Portland cement the ultimate degree of hydration can be calculated using Mill’s formula. Reference value of ultimate hydration degree of Portland cement (water-to-cement ratio ≈ 0.5) could be 75%, yes, the corresponding reaction degree is 100%.
Single chamber ball mills (with classifying liners and dam ring) with drying chamber and static or dynamic separator are commonly existing for coal grinding in cement plant for one or more kilns as per capacity. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Grinding media consists
(If Blaine is the only controlling device where blended cement is made, here L/S or Fly-ash — a small increase in target Blaine number is advisable and it will not have any adverse effect on mill feed rate). Nowadays, high efficiency dynamic separator is in use — not only to improve product quality but to enhance mill volume utilization factor.

Degree of Hydration. In fact the h max will be given by W/C divided by 0.36 e.g. if the water cement ratio is 0.3 degree of hydration will be 0.3/0.36 maximum degree of hydration attainable is 0.3/0.36. But this is no problem any way because anhydrate cement if it is there in the system it does not cause any harm to the concrete or cement paste

The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.

The degree of cement hydration of the fly ash-cement system can be calculated under various conditions according to , as shown in Figure 6. It was found by comparing the curing times in Figure 6 that the degree of cement hydration was higher than that of pure cement paste under the same conditions when fly ash was mixed into the cement paste
