Abstract Owing to their high energy efficiency, stirred mills are commonly used in the fine or ultrafine grinding of low-grade and fine disseminated ores to enhance liberation. In this study, batch wet grinding studies were conducted in a stirred mill to evaluate the effect of the grinding media density, grinding media diameter, and stirrer tip speed on the ground products and …

Stirred Media Detritor (SMD) is a fluidized media grinding mill. It utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media and slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces that produce the desired grinding mechanism for fine grinding.
Abstract Stirred media mills are used by the mining industry for ultrafine grinding to enhance liberation, and to decrease particle sizes of industrial minerals to tailor functional properties. This review describes stirred media mill technologies and operating principles, and summarises stress intensity theory which can be used for selecting efficient operating conditions.
Publisher Summary This chapter discusses the design, physical fundamentals, grinding behavior, operating behavior and scale-up of stirred media mills. The chapter shows possibilities to develop new and optimize existing grinding processes with stirred media mills. As stirred media mills are operated usually wet, the chapter focuses on wet grinding.

In this paper,based on the establishment of laboratory model,we have studied the effects of media size and amount on the grinding efficiency of vertical stirred mill. The results indicate that smaller size media is conducive to improve the energy density and increase the specific surface area of grinding in the mill cylinder,while larger size media enhances the volume of grinding space and ...
Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. The year 1948 saw the successful application of DuPont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning
