1. PYNPUNT GEDREWE OPENING

Managing a cement plant’s material handling and grinding circuit is a continuous battle against inefficiency and unplanned downtime. Are you facing these persistent challenges with your Vertikale Rolmeul (VRM) stelsels?

Hoë spesifieke energieverbruik: Inefficient grinding dynamics and excessive pressure loss can drive power costs 1015% above optimal levels, winsmarges direk erodeer.
Frequent Wear Part Replacement: Premature failure of rollers and table liners leads to costly shutdowns, high inventory costs for spare parts, and unpredictable maintenance budgets.
Inkonsekwente produkfynheid & Uitset: Fluctuations in feed material or mechanical instability result in offspec Blaine values, reducing kiln feed quality and limiting overall plant throughput.
Kompleks & Lang onderhoud: Traditional designs require extensive manual labor and prolonged downtime for roller servicing, belyningskontrole, and classifier overhauls.
Stelselintegrasie Hoofpyne: Outdated control interfaces and nonmodular components complicate integration with modern plantwide automation systems, creating data silos.

What if your VRM could deliver predictable performance, lower your costperton, and align with your longterm operational strategy?

2. PRODUK OORSIG

Our whitelabel Vertikale Rolmeul (VRM) is engineered for the drygrinding of raw materials, klinker, granulated blast furnace slag, vlieg as, and pozzolana in cement production. It serves as the core of the grinding circuit, transforming feed material into a finely ground product with precise particle size distribution.

Operasionele werkvloei:
1. Voer Inleiding: Material is fed centrally onto the rotating grinding table via a precision screw feeder or rotary valve.
2. Maalwerk & Droog: Hydraulically loaded rollers exert controlled pressure on the material bed. Terselfdertyd, hot gas from a preheater or auxiliary furnace flows through the mill housing, drying the feed as it is ground.
3. Materiaal vervoer & Klassifikasie: The gas stream carries ground particles upward to an integrated highefficiency dynamic classifier. Oversize particles are rejected back to the grinding table for further comminution.
4. Produk skeiding & Versameling: Inline particles exit with the gas to downstream bag filters or electrostatic precipitators for final product collection.

Toepassingsomvang: Ideal for new greenfield plants or retrofits requiring highcapacity grinding (50350 t/h) with integrated drying capabilities. Suitable for raw meal, sement, and slag grinding applications.

Beperkings: Not designed for wet grinding processes or for materials with extreme abrasiveness without specific alloy modifications. Maximum feed size is typically limited to 58% of roller diameter.
