A 17 t/h limestone grinding line is built around one mill rated 8-20 t/h, not two smaller units. Baichy publishes theMTW138 trapezium mill at 8-20 t/h on limestone at Mohs 3, configured with a PE250X400 jaw crusher, a TH250 bucket elevator, a vibrating feeder, a silo and one electric control cabinet.
17 t/h Limestone Grinding Line
What Equipment Does a 17 t/h Limestone Grinding Line Include?
A 17 t/h limestone grinding line has four stations — coarse crushing, storage and feeding, grinding with built-in classification, and powder collection — plus one electrical control cabinet.

| Silo | — | — | 1 |
| Electric control cabinet | — | — | 1 |

Process Flowchart of the MTW Grinding Production Line
The MTW138 grinding host carries four rollers of Ф460×260 mm against a Ф1380x260 mm ring at 96 rpm. The PE250X400 jaw crusher has a 250x400 mm feed opening, a 210 mm maximum feed size and a published capacity of 5-20 t/h. The TH250 bucket elevator conveys 31-48 m³/h with a 35 mm maximum granule size.
Which Mill Produces 17 t/h on Limestone?
An MTW138 trapezium mill published at 8-20 t/h and an SRM1300 vertical roller mill published at 10-28 t/h both bracket 17 t/h. The YGM160 stops at 16 t/h and the MTW175 starts at 20 t/h on their own product pages, so neither reaches 17 t/h.
| Mill type | Model | Max feed size | Product fineness | Capacity (t/h) | Main motor (kW) |
|---|---|---|---|---|---|
| High-pressure roller mill | YGM160 | ≤30 mm, 25–30 mm recommended | 80–425 mesh | 8–16 | 132 |
| Trapezium mill | MTW138 | <35 mm | 1.6–0.038 mm, 80–400 mesh | 8–20 | 110 |
| Trapezium mill | MTW175 | <40 mm | 1.6–0.038 mm | 20–35 | 200 |
| Vertical roller mill | SRM1300 | 38 mm | 212–45 μm, 70–325 mesh | 10–28 | 132–200 |
| Ball mill | 2100 × 4500 | ≤25 mm | 0.074–0.4 mm | 8–43 | 245 |
The MTW category page also publishes the MTW138 at 6-20 t/h with a 90 kW main motor and the MTW175 at 10-35 t/h, so the category page and the two product pages above disagree on the MTW138 grinding mill. This article uses the product-page figures.
What Materials Can a 17 t/h Limestone Grinding Line Process?
Limestone is calcium carbonate at Mohs 3 with a Bond work index typically between 6 and 12 kWh/t, so roller grinding carries no heavy wear penalty. The MTW series publishes medium-hardness non-metallic minerals — limestone, calcite, barite, talc, bentonite and gypsum at Mohs ≤6 — with feed moisture below 6% and a fineness range of 80-400 mesh.
In a limestone powder grinding plant, the end use sets the target mesh: 250-325 mesh for power-plant flue-gas desulfurization at CaCO₃ ≥90% and MgCO₃ ≤5%, 400-1250 mesh for ground calcium carbonate filler, and 200-325 mesh for dry-mix mortar and putty powder. The limestone grinding mill plant page sets out the same four stages.

How Do You Check Feed Size, Fineness and Moisture Before Ordering?
Four published values decide whether a 17 t/h limestone grinding line delivers 17 t/h.
Crusher outlet against mill feed — the PE250X400 publishes a 25-60 mm outlet range and the MTW138 a maximum feed size under 35 mm, so the jaw crusher is set at 25-35 mm.
The mesh basis behind the capacity figure — the MTW guide states that mill capacity is quoted at 200 mesh, and that grinding to 325 mesh instead of 200 mesh moves output by 20% to 40%. A 17 t/h duty named at 325 mesh is a different machine.
Feed moisture — the MTW138 publishes a material moisture limit of 6%, while the vertical roller mill table publishes a 4% maximum input moisture with a final moisture of ≤1%.
Installed power — the MTW138 grinding system publishes 110 kW on the host, 132 kW on the fans and 11 kW on the analyzers, plus 15 kW, 4 kW and 0.2 kW on the auxiliary machines.
FAQ: 17 t/h Limestone Grinding Line
Which mill size is right for a 17 t/h limestone grinding line?
An MTW138 trapezium mill published at 8-20 t/h or an SRM1300 vertical roller mill published at 10-28 t/h. A YGM160 mill is published at 8-16 t/h and an MTW175 at 20-35 t/h, so both fall outside a 17 t/h duty.
How much installed power does a 17 t/h limestone grinding line draw?
The MTW138 configuration table publishes 110 kW for the grinding host, 132 kW for the fans and 11 kW for the analyzers, plus 15 kW for the PE250X400 jaw crusher, 4 kW for the TH250 bucket elevator and 0.2 kW for the vibrating feeder. The YGM160 line publishes 305.45 kW installed.
Can one 17 t/h line make both 200 mesh and 325 mesh limestone powder?
Yes, within the published fineness range. The MTW138 publishes a 1.6-0.038 mm product, which covers 200 mesh and 325 mesh, and fineness is set at the analyzer. The MTW guide puts the output gap between 200 mesh and 325 mesh at 20% to 40%.
What feed size must the jaw crusher deliver to a 17 t/h limestone mill?
The MTW138 accepts a maximum feed size under 35 mm and the PE250X400 jaw crusher publishes a 25-60 mm outlet range, so the jaw crusher is set between 25 mm and 35 mm. The MTW175 publishes a maximum feed size under 40 mm, and the SRM1300 vertical roller mill publishes 38 mm.
What is the maximum material moisture for a 17 t/h limestone grinding line?
The MTW138 publishes a material moisture limit of 6%, and the SRM vertical roller mill table publishes a 4% maximum input moisture with a final moisture of ≤1%. Limestone feed above those limits needs a pre-drying stage.
