PF1214 Impact Crusher
The PF-1214 impact crusher is one of the most widely used impact crushing machines in the mining, quarrying, and aggregate industries. Built by Baichy Heavy Industry — a professional manufacturer of mining crushing, ore grinding, and mineral processing equipment — this medium-fine crushing unit balances throughput, reduction ratio, and operating cost better than most competing models in its class. If you are planning a new crushing plant or upgrading an existing line, the PF-1214 impact crusher deserves a serious look.
What Is the PF-1214 Impact Crusher?
The PF-1214 impact crusher is a medium-fine secondary crushing machine that uses high-speed rotating blow bars to strike incoming rock, shatter it against impact plates, and discharge material in the required size range. The "PF" prefix stands for the impact (反击) series, while "1214" refers to a rotor diameter of 1250 mm and a rotor length of 1400 mm. As a medium-fine crusher, it sits between a primary jaw crusher and a final tertiary crusher in the crushing circuit, typically taking feed from the primary stage and delivering a product ready for screening or milling.
What makes the PF-1214 impact crusher especially attractive is its combination of a high reduction ratio and a cubical, well-graded product. Because the material is fractured along natural cleavage planes by impact rather than squeezed, the finished aggregate tends to be more cubical — a property that directly improves concrete strength and asphalt performance.
PF-1214 Impact Crusher Technical Specifications
Before choosing an impact crusher, you need hard numbers. The table below summarizes the key technical parameters of the PF-1214 impact crusher. (Values are typical industry specifications — always confirm the final data with the manufacturer for your specific configuration.)
| Parameter | PF-1214 Specification |
|---|---|
| Rotor Diameter × Length | 1250 × 1400 mm |
| Feed Opening Size | 400 × 1430 mm |
| Max. Feed Size | ≤350 mm |
| Processing Capacity | 90–160 t/h |
| Motor Power | 132–160 kW |
| Discharge Opening Range | 30–80 mm |
| Machine Weight | ≈18–19 t |
| Application | Medium-fine crushing of limestone, granite, basalt, river stone |
| Output Gradation | Cubical, well-graded aggregate |
This specification set puts the PF-1214 impact crusher squarely in the mid-range of the PF series. It is powerful enough for a medium-size quarry yet compact enough for a modular, relocatable plant. The 90–160 t/h capacity range makes it a natural fit for producing 0–5 mm, 5–10 mm, and 10–20 mm aggregates, road-base material, and manufactured sand feed.

How the PF-1214 Impact Crusher Works
The Impact Principle
Understanding the working principle of the PF-1214 impact crusher helps you run it for maximum output. Feed material enters through the feed opening and falls onto the high-speed rotor. The rotor spins blow bars at high velocity, and each blow bar hurls the rock against fixed impact plates mounted on the machine housing. On impact, the rock fractures along its natural weak planes. The process repeats until the crushed fragments fall below the adjustable discharge opening and exit the crusher.
Three Crushing Zones
Most modern impact crushers, including the PF-1214, use three crushing zones: the primary impact zone (rotor blow bar to the first impact plate), the secondary zone (material thrown back across the chamber), and the tertiary zone near the discharge where fine material is shaped. This staged action is why the PF-1214 impact crusher delivers such a consistent, cubical product with a single pass.
Key Advantages of the PF-1214 Impact Crusher
- High reduction ratio — The PF-1214 impact crusher can reduce large feed in a single stage, lowering the number of machines in your circuit and cutting capital and energy costs.
- Cubical product shape — Impact crushing produces more cubic, evenly graded aggregate than compression crushing, improving the quality of concrete and asphalt end products.
- Adjustable output size — The discharge opening is easily adjusted to match your required gradation without stopping production for long.
- Simple structure and low maintenance — Blow bars and impact plates are the main wear parts; replacing them is straightforward, and the machine has a proven track record for reliability.
- Good for medium-hard and soft rocks — Limestone, dolomite, and similar medium-hard material are processed at low cost per ton, making the PF-1214 impact crusher highly economical.
- Low operating cost — With reasonable blow-bar life on suitable material and efficient motor sizing, the per-ton crushing cost stays competitive.
Where to Use the PF-1214 Impact Crusher
The versatility of the PF-1214 impact crusher explains its popularity. Typical applications include:
- Aggregate production — producing crushed stone for concrete, road construction, and railway ballast.
- Limestone processing — the most common and most economical feed for this impact crusher.
- Manufactured sand feed — preparing feed for sand-making circuits in ready-mix and infrastructure projects.
- Basalt and granite lines — handling medium-hard rock where impact crushing delivers good product shape.
- Recycling applications — processing reclaimed asphalt pavement and construction debris.
For many operators, the PF-1214 impact crusher is the ideal "workhorse" that turns primary crusher output into marketable aggregate with minimal supervision.
How to Choose the Right PF-1214 Configuration
Choosing an impact crusher is about matching the machine to your material and target output. For the PF-1214 impact crusher, consider four factors:
1. Feed size and hardness — Ensure your feed is within the ≤350 mm limit and match the blow-bar alloy to your rock's abrasiveness.
2. Required capacity — Size the circuit so the 90–160 t/h range leaves headroom for peak demand.
3. Target gradation — Set the discharge opening and, if needed, pair the crusher with screening to hit exact product specs.
4. Wear-part strategy — Order spare blow bars and liners in advance to minimize downtime in high-production seasons.
When in doubt, consult Baichy's engineers with your material test data — the right configuration can raise throughput and cut operating cost significantly.

PF-1214 Impact Crusher: Is It the Right Investment?
Every crushing investment comes down to a simple question: does the machine deliver the tonnage, product quality, and cost you need? The PF-1214 impact crusher answers yes for a broad range of medium-hard rock applications. Its combination of high reduction ratio, cubical output, simple maintenance, and proven field reliability has made it a staple in quarries across Asia, Africa, the Middle East, and Latin America. Paired with proper feeding and screening, this impact crusher reliably produces the aggregates that hold up roads and buildings.
Frequently Asked Questions (FAQ)
1. What is the capacity of the PF-1214 impact crusher?
The PF-1214 impact crusher has a processing capacity of approximately 90–160 tons per hour, depending on the feed size, rock hardness, moisture content, and discharge opening setting. Softer material such as limestone typically allows the higher end of the range.
2. What is the maximum feed size for the PF-1214 impact crusher?
The maximum feed size for the PF-1214 impact crusher is around 350 mm. Feeding oversized material can damage the blow bars and reduce efficiency, so it is important to control feed size upstream with a primary crusher and, where needed, a grizzly feeder.
3. What materials can the PF-1214 impact crusher process?
The PF-1214 impact crusher is best suited to medium-hard and soft rocks, including limestone, dolomite, granite, basalt, and river stone. It is also used for recycling construction waste. For highly abrasive hard rock, consider wear-part upgrades or a different crushing method to control cost.
4. What are the main wear parts, and how often do they need replacement?
The main wear parts of the PF-1214 impact crusher are the blow bars and the impact plates (liners). Replacement intervals depend on the abrasiveness of the feed and operating hours. On typical limestone applications, blow bars can last a meaningful production season, but it is wise to keep spares on hand.
5. Is the PF-1214 impact crusher suitable for a complete crushing plant?
Yes. The PF-1214 impact crusher is commonly installed as the secondary crushing stage after a jaw crusher in a complete plant. It pairs well with a vibrating feeder, screening machine, and a final tertiary or sand-making unit, forming a full aggregate production line.
