HRP Hydraulic Roller Press 2 Increase energy efficiency and throughput Main features Highpressure roller grinding of cement clinker and hard brittle materials is a This makes it possible to increase the throughput of a given size ball mill and Two types of wear lining are modern and very energyefficient reduce the specific power consumption available – welded hardfacing process.
the roller press process and. the vertical roller mill process. Ball mill. Most existing ball mills designed for grinding Portland cement are not particularly suited for drying wet materials like slag and slag cement. However, the ability to dry the feed materials can be increased significantly if a hot gas generator is included in the
At present, cement grinding is mainly composed of ball milling or roller press + ball mill composed of different grinding system. Vertical roller mill has been widely used in grinding cement raw materials and pulverized coal because of its simple and convenient, energy efficient, stable and reliable, low noise and other characteristics, but for ...
KHD will supply a Roller Press RP7170/90 along with an SKS VC 3000 Separator, which will increase the grinding capacity of the current ball mill by more than for a total guaranteed production capacity of 150 tph (PPC 3600 Blaine).
Grinding process The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently
Roller mills. These have been used for many years for the less exacting rawmilling process, but recently roller mills, in combination with highefficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient.
Improving knowledge of grinding technology and mill operations to operate, optimise and troubleshoot ball mill and vertical roller mill grinding installations. Ball mills and vertical roller mills are used for many grinding applications in cement production: raw meal grinding, coal and pet coke, and finish cement grinding.
Cement grinding Vertical roller mills versus ball mills. grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system.
The roller press is a new type energy saving cement grinding equipment developed in the mid 1980s. It can completely or partially replace the ball mill that is highly energy consuming. In addition, featuring the functions of low material consumption and low noise, this roll squeezer is an ideal choice for both new factory construction and old ...
