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.

Fine particles by Micronization Mill System Our revolutionary pulverizing machine replaces the likes of a conventional ball mill, impact mill, hammer mill, Raymond mill, tower mill, etc. An ultra-fine raptor works by means of a tornado/vortex airstream. With the help of a generated high-frequency air pressure fluctuation and a rotating impeller, the airstream transports the material into the mill s spiral chamber. From there, the particles are distributed evenly into the milling chamber. We are pleased to start commercial sales of proprietary machine but it will be licensing package. We provide a complete manufacturing drawings so that buyer will own manufacture in locally and sell it to local market only. We provide one machine and drawings.
