PEX-250×1200 Fine Jaw Crusher
In any mineral processing or aggregate line, the crusher between the primary machine and the grinding mill often decides plant profitability. That is where the PEX-250×1200 fine jaw crusher from Baichy Heavy Industry earns its reputation — turning oversized primary products into a consistent, mill-ready feed with low downtime and strong energy efficiency.
What Is a PEX-250×1200 Fine Jaw Crusher?
The PEX-250×1200 jaw crusher is a secondary fine crusher that accepts feed up to 210 mm and reduces it to a 20–60 mm discharge range. Unlike larger PE primary jaws, the PEX series uses an extra-wide, shallow cavity — a 250×1200 mm feed opening that is long but narrow, making it excellent at handling flat, slab-like and elongated materials that jam other designs.
In simple terms: the primary crusher does the heavy breaking; this fine jaw crusher does the finishing work that prepares stone for ball mills, impact crushers or screening — one of the most trusted secondary jaw crusher solutions across Asia, Africa and Latin America.

How the PEX-250×1200 Fine Jaw Crusher Works
Structural diagram of the PEX series jaw crusher
A fixed jaw plate and a movable jaw plate hang on an eccentric shaft. As the shaft rotates, the movable jaw swings against the fixed plate, progressively crushing material as the gap narrows from the wide feed opening to the discharge end. Because the chamber is wide but shallow, flat stones are gripped across their full width instead of tumbling through uncrushed — the result is better particle shape, fewer elongated pieces, and a more consistent product for downstream screening and grinding.
Key Design Advantages
1. High Crushing Ratio, Consistent Output
The deep-wedge cavity and optimized speed deliver a high ratio in one pass, producing uniform 20–60 mm discharge and lowering the load on downstream mills.
2. Robust, Low-Wear Construction
High-manganese steel jaw plates with a proven tooth profile extend liner life; heavy-duty bearings and a balanced flywheel absorb impact, cut vibration, and reduce maintenance.
3. Energy Efficiency
At just 37–45 kW for up to 52 t/h, per-ton energy cost is among the lowest in class — real electricity savings for around-the-clock operations.
4. Simple, Safe Maintenance
Discharge is adjusted with shims (or a hydraulic wedge on some builds) in minutes. Plates are reversible and easy to swap, with open side covers for safe access, plus lifelong Baichy technical support and a spare-parts guarantee.
5. Compact Footprint
Roughly 2140×1660×1500 mm and under 10 t, it fits stationary, containerized and semi-mobile plants where space is tight.
Application Scenarios
Aggregate and sand — 20–60 mm aggregate for concrete and road base.
Iron ore and non-ferrous mines — consistent ball mill feed.
Limestone, granite, basalt, quartz — medium-hard to hard, abrasive feed.
Construction waste recycling — secondary crushing of recycled concrete.
Coal and industrial minerals — fine sizing before beneficiation.
What It Is NOT For
It is not a primary crusher and must not receive feed over 210 mm. For ultra-cubic aggregate (asphalt specs), pair it with an impact or cone crusher.
Operating Costs and ROI
Price is only the start; compare total cost of ownership:
| Cost Item | What to Check | PEX-250×1200 Advantage |
|---|---|---|
| Energy | kW per ton | 37–45 kW → low electricity |
| Wear parts | Liner life & price | High-manganese, reversible plates |
| Downtime | MTBF & service ease | Simple shim adjust, quick liner change |
| Spares | Local stock & lead time | Baichy global spare support |
| Support | Lifelong service | Manufacturer-direct engineering |
Many operators find that energy savings alone recover the price difference within the first one to two years of continuous duty.
PEX-250×1200 vs. PE Primary vs. Cone Crusher
| Comparison | PEX-250×1200 | PE Primary Jaw | Cone Crusher |
|---|---|---|---|
| Stage | Secondary | Primary | Secondary/Tertiary |
| Max Feed | ≤210 mm | 300–1020 mm | ≤300 mm |
| Output Shape | Good | Coarse | Excellent cubicity |
| Best For | Flat material, mill feed | Run-of-mine rock | Hard rock, cubic aggregate |
| Cost | Lower | Lowest per ton | Higher |
| Wet/Clay Feed | Handles well | Limited | Poor (clog risk) |
For many medium-hard and flat-material operations, this fine jaw crusher offers the best cost, durability and output-control balance where a cone crusher is overkill.
How to Choose the Right Fine Jaw Crusher
• Measure actual max feed — must be ≤ 210 mm.
• Define the discharge size your next stage needs (20–60 mm).
• Size capacity at 70–85% of nameplate for steady operation.
• Match liner to abrasiveness — high-manganese for hard rock.
Confirm power and footprint, and ask for a process flow design — Baichy engineers size the whole line.

Frequently Asked Questions
1. What is the max feed size for the PEX-250×1200 jaw crusher?
210 mm. Feeding larger rock can clog the cavity or damage plates, so pre-screen or use a primary crusher first.
2. What is the processing capacity?
Approximately 16–52 t/h depending on discharge setting and material — harder ore runs lower, limestone higher.
3. How do I adjust the discharge opening?
Adjust within 20–60 mm using shims (or a hydraulic wedge on some builds): loosen the tension mechanism, add or remove shims, retighten — typically 10–20 minutes.
4. Can it crush hard rock like granite or basalt?
Yes — it handles granite, basalt, quartz and iron ore. For abrasive feed, choose high-manganese or alloy composite plates and monitor wear.
5. Is it a primary or secondary crusher?
It is a secondary (fine) crusher — designed to take 210 mm feed from a primary unit and produce 20–60 mm output for mills, impact crushers or screening. Not for run-of-mine feed.
