NEO MAKİNA ve MÜHENDİSLİK A.Ş. engineers and installs cement production plants: cement grinding and packing plants (grinding stations) and the mechanical, thermal and environmental equipment of clinker production lines. Clinker, gypsum and additive (limestone, slag, pozzolan, fly ash) dosing, closed-circuit grinding with ball mill or vertical roller mill (VRM), cement silos, bagged and bulk dispatch units are engineered turnkey at 10–150 t/h for CEM I, II, III and IV cements to EN 197-1.
Plant Types
Cement Grinding and Packing Plants (Grinding Stations)
- Plants that grind externally supplied clinker into cement; built near ports, logistics hubs and markets; investment about one-third of an integrated plant.
- Scope: raw-material reception and storage, dosing, grinding, separator, filter, cement silos, packing and bulk loading.
Integrated Clinker Line Equipment
- Raw-material crushing and pre-homogenisation, raw mill, preheater-calciner, rotary kiln, clinker cooler, coal/petcoke grinding and pulverised firing, flue-gas filtration and waste-heat recovery (ORC / steam).
- Capacity increase, energy-efficiency and emission-reduction projects at existing plants; refractory works (Industrial Refractory Technologies).
Grinding Technologies
Ball Mill Systems
- Two-chamber tube mill in closed circuit with high-efficiency dynamic separator (3rd generation); high-chrome liners and ball charge.
- Proven, easy-to-operate technology for high fineness (CEM I 42.5 R / 52.5 N, 3,800–4,500 cm²/g Blaine) and slag grinding.
- Specific energy 30–40 kWh/t; 20–30% reduction with a pre-grinder (HPGR).
Vertical Roller Mill (VRM) Systems
- Grinding, drying and separation in one unit; processes additives with up to 15% moisture using hot gas.
- 30–40% lower energy than ball mills (20–28 kWh/t), compact layout, fast product changeover.
- 50–300 t/h capacities for cement, slag and raw-meal grinding.
Process Flow (Grinding Plant)
- Reception and storage: Covered storage hall or silos for clinker, gypsum and additives; truck/ship unloading, belt conveyors and bucket elevators.
- Dosing: Weigh-feeder proportioning to recipe (±1%); automatic recipe change.
- Grinding and separation: Closed-circuit mill-separator; fines to filter, coarse back to mill; mill temperature control by water spray, grinding-aid dosing.
- Dust collection: Jet-pulse bag filters on mill and transfer points; emissions <10 mg/Nm³.
- Storage: 1,000–10,000 t concrete or steel cement silos; aerated bottoms, multi-compartment silos.
- Dispatch: 8–16 spout rotary packers (2,000–4,000 bags/h), pallet and truck-loading robots; telescopic bulk loaders for tankers; big-bag filling.
Quality and Automation
- Product quality: Online particle-size/Blaine monitoring, sulphate (gypsum) balance for stable setting time and early strength; laboratory integration.
- Automation: PLC/DCS optimisation of mill load, separator speed and fan flow; specific-energy monitoring; dosing and packing traceability; SCADA control room.
- Safety and environment: Dust-free working environment, noise insulation, dust-explosion protection (ATEX in coal grinding).
Typical Application Range
- Grinding capacity: 10 – 150 t/h (grinding plant); clinker-line equipment 500 – 3,000 t/day
- Products: CEM I, CEM II (limestone, pozzolanic, composite), CEM III (slag), CEM IV, ground granulated blast-furnace slag (GGBS), calcium aluminate and special cements
- Standards: EN 197-1, EN 196 (test methods), CE Machinery Directive, ATEX, national industrial air-pollution regulation
Why NEO MAKİNA?
In cement plant projects, crushing, conveying, grinding, dust collection, firing, refractory, steel structure and automation are engineered by the same team; mill selection (ball/VRM) is made according to investment budget, energy cost and product portfolio. We offer compact grinding-plant solutions and site erection for overseas markets (Africa, Central Asia, Middle East).
Frequently Asked Questions
Ball mill or VRM?
Ball mill for low investment, proven operation and very high fineness; VRM for low energy, moist additives and fast product changes. Above 100 t/h the VRM is usually more economical.
How much investment does a grinding plant need?
It depends on capacity, mill type and silo/packing scope; for a 50 t/h plant a feasibility and budget proposal is prepared together with clinker supply conditions.
Can my existing mill's efficiency be improved?
Yes. Separator upgrade, liner and ball-charge optimisation, pre-grinder addition and automation deliver 10–25% capacity increase or energy savings.
