Exshaw FM2 successfully uses this idea to make the mill sweep dust fine enough for finish cement. However the box is extremely large to accomplish this. As a rule of thumb for cement mills, the air velocity around the discharge trunnion and hood must be less than 4 m/s. In Exshaw's dropout box they strive for about 2 m/s.

What Is Air Swept Coal Mill. The air-swept coal mill is also called a coal grinder. It is the main equipment of the cement plant, used for drying and pulverizing coal powder.It mainly consists of the feeding device, main bearing, rotary part, transmission device, discharging device, high-pressure starting device, and lubrication system.
Evaluate and correction. • Average ball size in chamber 2 is too small (average 16 mm, PW 17 g.) • Take charge distribution more coarse to increase PW and average ball. size …
the capacity of grinding and drying of mill. The grindability affects the capacity of grinding, type of mill and roller pressure. The capacity of the mill is calculated Using G K * D 2.51 Where, G is capacity of the mill, K1 is roller mill coefficient and D is table diameter. 2. PROCESS CONTROL OF VRM The conventional control system of VRM
Advantages of cement ball mill. Less investment: cement ball mill with advantages of a perfect motor system, low energy consumption and power consumption, and ultra-low operating cost, which can save a lot of cost …
An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.
The design of the dust seals was inadequate, as evidenced by the presence of silica inside the rolls. The damage to the bearings was more severe on the yoke side (seal side) …
The most common is the mill outlet seal. This is usually a soft felt or rubber seal that seals the gap between the rotating mill shell and the static outlet housing. ... If the seal is covered in hard cement dust, this is often an indication that the seal has not been maintained for some time. The seal gap should be no more than 1mm, but is ...

Ductwork (dust highway) The ductwork is the highway of the dust collection system. Proper duct velocity for most cement applications should be between 3500 and 4000 fpm (18 – 20 m/sec.) Speeds lower than 3500 fpm will allow dust in the airstream to fall out, causing dust buildup in the duct.
In cement mills, trunnions often take the form of split trunnions or slide shoe bearings. ... Mill trunnion seals must be designed to withstand operating conditions and effectively keep out dust, moisture and other contaminants that can affect mill trunnion bearing performance. 6. Proper lubrication is vital for trunnion longevity and performance.
