uller is one of the largest and most comprehensive designers of process equipment for the cement industry, with over 100 years of experience in milling technology. Fuller’s experience includes the design of nearly all types of mills, parators and auxiliary equipment, plus the process design of the systems in which they are ud. The Fuller design of roller mills has evolved over many years, bad on operational experience with the harder, more abrasive materials found in certain areas of the U.S., India, China and Korea, and the high-moisture raw materials found in Indonesia and the Philippines. Experience with the difficult materials has led to many refinements in the mill design,resulting in a more reliable and efficient mill for any application.Fuller has extensive experience in testing raw materials to determine the correct mill lection and process design for any situation. Our laboratory testing capabilities include a variety of standard testing, as well as the equipment and process knowledge for pilot testing new developments.

INTRODUCTION
Vertical roller mills are widely accepted as the
most efficient means of preparing kiln feed for the
production of cement clinker. They are capable of
preparing a wide range of feed materials to the
紫丹活血片required fineness in an energy-efficient process.
Although cement raw materials vary considerably
in grindability, drying requirements and abrasion,

the roller mill has the flexibility to be adapted to
the variations, as well as other specific site
requirements. The Fuller Roller Mill (FRM™) ranks
as one of the most technically advanced and efficient
mills available today.
The FRM system us the friction and pressure
generated between a roller and the rotating table
to crush and grind cement raw material. Feed
material is directed onto the center of the table by
the feed chute. The rotation of the table distributes
material and pass it under the rollers. The height
of the dam ring is adjustable and ts the depth of
the grinding bed on the table. Partially ground
material spills over the dam ring into the hot gas
stream coming from the nozzle ring, and the
moisture in the material is immediately evaporated.斯托克电影
The finer portion of material is carried by the gas
stream to the parator while the coarr portion is
deflected directly back to the table. The parator
allows material that has reached the specified size
to leave the mill, while it rejects oversized material
and nds it back to the table for further grinding
