1. PAINPOINT DRIVE NOLEING

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 Босоо галзуу тээрэм (VRM) системүүд?

Өндөр хувийн эрчим хүчний хэрэглээ: Inefficient grinding dynamics and excessive pressure loss can drive power costs 1015% above optimal levels, ашгийн хэмжээг шууд бууруулж байна.
Байнга элэгддэг эд ангиудыг солих: Premature failure of rollers and table liners leads to costly shutdowns, high inventory costs for spare parts, мөн урьдчилан таамаглах боломжгүй засвар үйлчилгээний төсөв.
Тохиромжгүй бүтээгдэхүүний нарийн чанар & Гарц: Fluctuations in feed material or mechanical instability result in offspec Blaine values, reducing kiln feed quality and limiting overall plant throughput.
Цогцолбор & Lengthy Maintenance: Traditional designs require extensive manual labor and prolonged downtime for roller servicing, Зэрэгцээ шалгах, and classifier overhauls.
Системийн интеграцийн толгой өвдөх: Outdated control interfaces and nonmodular components complicate integration with modern plantwide automation systems, creating data silos.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. БҮТЭЭГДЭХҮҮНИЙ ТОЙМ

Our whitelabel Босоо галзуу тээрэм (VRM) is engineered for the drygrinding of raw materials, тархины өрөө, нунтагласан тэсэлгээний зуухны шаар, дэгдэмхий үнс, 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.

Үйл ажиллагааны ажлын урсгал:
1. Тэжээх танилцах: Material is fed centrally onto the rotating grinding table via a precision screw feeder or rotary valve.
2. Цайны нунтаг & Хатаах: Hydraulically loaded rollers exert controlled pressure on the material bed. Нэгэн зэрэг, hot gas from a preheater or auxiliary furnace flows through the mill housing, drying the feed as it is ground.
3. Материал тээвэрлэлтийн тээвэр & Ангилал: 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. Бүтээгдэхүүнийг салгах & Цүглуулга: Inline particles exit with the gas to downstream bag filters or electrostatic precipitators for final product collection.

Хэрэглээний хамрах хүрээ: Ideal for new greenfield plants or retrofits requiring highcapacity grinding (50350 t / цаг) with integrated drying capabilities. Түүхий хоолонд тохиромжтой, цемент, and slag grinding applications.

Хувьсгал: 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.
