Pulverizer E-ACM
The ACM Pulverizer is a Fine Impact mill equipped with a built-in classifier used throughout the world for the fine grinding of various materials. In carbon black grit reduction applications, the low bulk density of the material made processing difficult with standard ACM designs. Continuous innovations to the ACM resulted in a new system capable of reducing grit levels from several hundred ppm down to as low as 1 ppm.
Principle of Operation
Grinding mechanism and features
Dispersion of the raw material is the most important factor in grinding grit particles (coarse particles). The unit features a pneumatic conveying mechanism to effectively disperse and carry the raw material to the grinding chamber. To process light materials such as carbon, it is important that all of the raw materials flow through the grinding chamber. To ensure that all materials pass through the fine impact mechanism, the E-ACM is designed to feed the materials from the bottom of the grinding rotor.
Recycle-grinding of classified materials
A valve at the classifying section discharges classified coarse particles back into the feed inlet via an ejector for re-grinding. The recycle percentage can be adjusted by controlling the ejector pressure. The optimal production conditions are determined by balancing the product quality and capacity.The explanation of this machine is also available in the video below.
Features
Grinding Efficiency
The grit level in the final product is influenced by the grit content of the raw material. This unit can produce high-grade carbon blacks with low capital investment and running costs.
System
The grinding unit is normally incorporated into the carbon black process line as an in-line unit. The blower is installed directly after the grinding unit to compensate for the pressure loss generated by the E-ACM.
