Decanter centrifuges process characteristics The separation process in a decanter centrifuge relies on a few process characteristics such as centrifugal force or force, sedimentation rate and separating factor, differential speed between the conveyor and bowl, and clarity of the liquid discharge. Decanter centrifuges require a centrifugal force for the separation of the solids from the liquid. This characteristic is dependent on the radius of the centrifuge and its angular rotational speed. A decanter centrifuge applies a force equivalent to several thousand , which reduces the settling time of the particles. It is also favored to maintain a large force, which will result in an improved separation. The rate at which sedimentation occurs is an important characteristic of the decanter centrifuge separation process. The sedimentation rate is influenced by the particle size, the shapes of the particles, their differential densities and the viscosity between the particles and the liquid. This process characteristic can be improved by utilizing flocculating agents. The sedimentation rate is also dependent on the separating factor of the decanter centrifuge, which is related to the centrifugal force. The exterior bowl and the scroll conveyor rotate at different high speeds. This differential speed between the two is accountable for the sedimentation throughout the decanter centrifuge cylinder. A high differential speed results in a smaller residence time of the cake settlement, so it is necessary to keep the cake thickness to a minimum to avoid impairing the discharge quality. Keeping the cake thickness to a minimum also aids in the improvement of the cake dewatering process. For this reason, it is necessary to obtain an optimal differential speed to balance the cake thickness and quality. The characteristic above all affects the clarity of the liquid output which is dependent on the volumetric throughout rate, where a higher flow rate will result in a poor liquid clarity. Another characteristic that influences the clarity of the liquid output is the differential speed. A low differential speed results in a better clarity, therefore, aiding in the separation process. The Force also plays a role in the clarity of the liquid discharge. Higher force results in an increase in the separation of the solid particles from the liquid and yields a better clarity.

Swivel type lead-bronze bushed trunnion bearings are generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion. The bushing is provided with end flanges thus assuring that the trunnion flanges run against a bronze face. On smaller mills rigid or swivel type bearings support the mill trunnions. The lower half of such bearings are lined with bronze or a special mill babbitt which is peened in place and bored to fit the trunnion. In all cases a low bearing pressure is maintained to assure freedom from overheating, long life and minimum maintenance. They are designed to provide support to the mill proper, its media and pulp load. Trunnion bearings are generally supplied with seals for use with a circulating oil lubrication system. They can be designed to accommodate block grease or oil with wool waste. For special applications trunnion bushings can be furnished constructed of Micarta to allow water lubrication or oil lubrication. In many dry grinding applications, or where heat is developed, the trunnion bearings can be furnished for water cooling. This system carries away the excess heat transmitted through bearings and protects them.

Straight subs: Used to connect drill stem members that have a similar OD. Reduced-section sub: Used to connect drill stem members that have different diameters that warrant the cross-sectional change necessary to accommodate different connections. Saver sub: Used to extend the life of the rotary kelly by taking the connection wear each time it is made up to a drill stem component. Bit sub: Size availability ranges from 3 1/8 in to 11inch OD and 36in to 48in length. Lift sub: A lift sub enables the safe, efficient handling of straight OD tubular, such as drill collars, shock tools, jars, directional equipment, and other tools, by using the drill pipe elevators. Top drive sub: Top drive subs serve as the sacrificial element between the drill string and the top drive, reducing repair and maintenance costs.
