It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are airswept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process.
Our company produced the trunnion bearings castings with high strength steel raw material. Our professional engineers also optimized the trunnion bearings technological structure base on ball mill operation process in the early stage. So can not only guarantee the stability of the part in the long run but also prolong the part working life.
The mill trunnion bearings are a key assembly in mill operation. If the trunnion bearings are not reliable the complete mill is not reliable. Various trunnion bearings designs are used, ranging from fully hydrodynamic to fully hydrostatic. The design charge load defined earlier is a direct input in the calculation of the trunnion bearing pressure.

Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills Grinding Action is carried out by a series of hinged or fixed hammers revolving in an enclosed chamber with wearresistant plates.
This mill controls product size and production quality with minimal power which reduces overall operating costs. Some additional construction features that offer advantages to the customer include journal assembly, vertical shaft hub connection, trunnion bearings dualoring, fabricated plow support and flange bearing for turbine classifier.
Feeding Size: ＜25mm. get price! Airswept coal mill is the main equipment of cement plant, also called coal mill in cement plant, used for grinding and drying various hardness of coal, crushing the coal briquette into pulverized coal. It is the important auxiliary equipment of pulverized coal furnace. The airswept coal mill runs reliably ...
2. Trunnion Seal The mill heads in a BTM are cast integral with trunnions that are supported in special heavy duty watercooled bearings. It is necessary for pressurized BTMs to utilize pressurized air seals between the rotating mill and mill inlet/outlet boxes (Figure 12). This prevents leakage of coal dust or air from the mill.

Trunnion Wheels. Trunnion wheels act as a cradle to support the weight of the rotating drum, while also providing a smooth service for the tire (riding ring) to ride against. As part of the drum's support base, problems with the trunnion wheels should be addressed immediately to avoid escalating damage. While trunnions can be resurfaced via ...

Trunnion Bearing Assembly Ball Mill Rod Mill The first part of the mill that we will look at is the TRUNNION BEARING. This is a HYDROSTATIC BEARING which is a slow moving bearing that carries a heavy load. Usually it is constructed from Babbitt's metal.
The ball tube mill consists of two perfectly symmetrical grinding circuits. It then passes through the trunnion tube whose screw conveyor conveys the coal into the mills. The mill drum carrying the ball charge rotates on antifriction bearings. Raw coal is fed to the drum through the inlet elbow and gets crushed to powder inside the mill drum. The ball charge and the coal are carried to certain ...
Only the best will do... Take the trunnion design. Drawing on years of knowledge and experience, our trunnion optimally balances strength and weight to best avoid the stress concentrations that cause cracking and failure. We've also improved the tightfitting joint to further reduce stress.
The trunnion bearing is installed at the periphery of the ball mill trunnion. These bearings provide smooth operation and low friction, enabling efficient grinding and blending of materials. The design and structure of trunnion bearing ball mills are carefully engineered to ensure optimal performance. The mill consists of a hollow cylindrical ...
A trunnion (from Old French trognon 'trunk') [1] is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. [2] Alternatively, a trunnion is a shaft that positions and supports a tilting plate. This is a misnomer, as in reality it is a cradle for the true trunnion ...
The drive shaft in Photo 6 was on a steelmill elevator. The surface is smoothest near the root of the keyway and became progressively rougher as the crack grew across the shaft. Numerous progression marks surrounding the tiny IZ and the change in surface condition about 40% of the way across the shaft from the IZ suggest something changed ...

Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 3548 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.
Coal mills High quality trunnion wins customer trust AGICO has set new standards in aftersales service and customer support. Our ear shaftsupported mills are backed by our global logistics and technical expertise. No matter where you are, our highquality components are readily available whenever you need them.
The trunnion is a kind of cylindrical and tubular shaft with thick walls, wherein the ore passes through its inner diameter, both in the feed and in the mill discharge. A pressurized oil film prevents metal to metal contact between the trunnion and the bearing bushing and allows the mill to rotate without excessive friction.
