Types of Ball Mill Feeders and Their Applications
Gravimetric Feeders. Gravimetric feeders are the most common type of ball mill feeders. These feeders measure the flow rate of the material and control the speed of the feeder to ensure that the ball mill is receiving the desired amount of material. The flow rate is typically controlled using a load cell that measures the weight of the material ...
The segregation of cement clinker particles in a mill-feeding hopper
In this work, a scaled model of the mill feeding hopper is established at the laboratory, supplemented with a video camera to analyze the particle flow velocity, and a sieving device to analyze the size distribution of particles at different times of discharge. The hopper is scaled to 1:5 smaller than the actual size. It includes three parts ...

PERFORMANCE EVALUATION OF A HAMMER MILL FOR …
These experiments were deduced to evaluate and compare the performance of the investigated hammer mills under the effects of three feeding rate levels (0.2, 0.4 and 0.6ton/h), four rotor speed levels (1200, 1500, 1800 and 2100rpm), and two screen hole diameter levels (9 and 14mm) using corn cobs. The performances of both machines were …
Raw Mill Hopper Feeding Cement Plant Namibia
The project included the replacement of the old raw coal feeding equipment to the mill, which consisted of an apron feeder, for the new design of rotor weighfeeder Pfister® TRW-K. Rotor weighfeeder Pfister® TRW-K installed in Carboneras is the first reference installation of raw coal and pet coke mill feeding in the cement industry.
