The HRP-R for raw meal lets you run the comminution process without adding water and with minimum power consumption.
The roller press for raw meal commutes raw meal and slag by subjecting it to high pressure between the counter rotating rollers. For raw meal grinding, the HRP is very suitable if dry material is present.
With dry raw material, the grinding economy will be even higher because there is no need to add water to the roller press during the process.
The normal set up is one or more HRP-Rs, built in a loop sharing static and dynamic separators.
The HRP-C is a dedicated machine for clinker grinding that lets you comminution process run, with minimum power consumption. The roller press grinds cement clinker and brittle material by subjecting it to high pressure, producing micro-cracks in the material as well as a substantial amount of fine material.The HRP-C can be applied in different combinations for clinker grinding. It can run separately or in conjunction with a small ball mill, providing a simple and economical mill system.As part of a ball mill upgrade, the HRP-C can increase capacity by up to 100%. As part of a new installation, it can reduce energy consumption by 20-30%, compared with traditional ball mill grinding systems. Built on innovative roller press technology, the HRP is one of FLSmidth’s most advanced and efficient units. A highly flexible solution, it is suitable for both new installations and upgrades.
Wear lining HRP rollers have a wear lining of welded hard-facing material and worn roller surfaces are reconditioned by welding. If desired, spot repairs or complete resurfacing can be performed with the rollers in situ.
Controlled feed system To facilitate a choke feed press, the HRP has a motorised feed-control gate that ensures the feed start is smooth and helps to adjust the throughput or power consumption of the press. The feed-control gate secures an overall smoother operation.
Configuration optionsThere are several ways that a roller press can be incorporated into a grinding system:
As well as the high grinding economy and the low investment, the HRP also has other benefits.
The few wear parts of the HRP reduce maintenance and operating costs.
The rollers are the only components exposed to wear from the grinding media, keeping the maintenance straightforward.
This means that the hourly cost of operation is kept at a minimum for the whole lifetime of the machine.
