When purchasing an impact crusher, have you ever been overwhelmed by similar model numbers like PF1007, PF1010, and PF1214? They look very similar, but their prices and outputs differ.
These model numbers aren't arbitrary; they hide the code of the equipment's key performance parameters. This article will thoroughly analyze the differences between these model numbers to help you make the most informed investment decision.
I. What Do the Numbers Represent?
First, we need to understand the naming rules for the PF series models. Taking PF1007 as an example:
• PF: An abbreviation of impact crusher in Pinyin.
• 1000: Represents the rotor diameter (D) as 1000 mm.
• 7: Represents the rotor length (L) as 700 mm.
Similarly, the rotor diameter of PF1010 is 1000 mm, and its length is 1050 mm; the rotor diameter of PF1214 is 1250 mm, and its length is 1400 mm. Therefore, the numbers in the model number directly reflect the size of the core component of the equipment the rotor. II. Comparison of PF1007, PF1010, and PF1214
The main difference between these three models lies in the rotor size and the matching motor power, which directly determines the equipment's processing capacity, feeding requirements, and output performance.

The comparison table below provides a clear overview:
| Model | Rotor Size (D×L) mm | Feed Inlet Size (W×L) mm | Maximum Feed Size (mm) | Processing Capacity (t/h) | Motor Power (kW) |
| PF-1007 | Φ1000×700 | 400×730 | 300 | 30-70 | 37-45 |
| PF-1010 | Φ1000×1050 | 400×1080 | 350 | 50-90 | 55-75 |
| PF-1214 | Φ1250×1400 | 400×1430 | 350 | 80-180 | 110-132 |
From the comparison, we can draw the following conclusions:
1. Increased Specifications and Output: From PF1007 to PF1214, the rotor diameter and length increase, meaning a larger crushing chamber and the ability to process more material at once, resulting in a significant increase in processing capacity (output).
2. Different Power Requirements: Driving a larger rotor and crushing more material requires a more powerful motor. Therefore, larger models require higher motor power and consequently, higher energy consumption.
3. Feed and Discharge: Larger models typically allow for larger feed particle sizes, and the adjustable range for discharge particle size may also be wider. However, the final discharge fineness depends on factors such as hammer wear and grate clearance.
III. How to Select the Right Model Based on Actual Needs?
The choice of model should not be based solely on price, but rather on a comprehensive consideration of your production needs:
• PF1007: Suitable for small to medium-sized production lines and projects with low output requirements. Advantages include low investment cost, small footprint, and economical energy consumption.
• PF1010: Ideal for medium-sized production lines, it strikes a good balance between output and power consumption, offering significantly higher capacity than the PF1007, and is a commonly used model.
• PF1214: Suitable for large-scale stone production lines, mines, and large-scale engineering projects, it meets the demands for high-output, high-efficiency crushing, making it a mainstay model for large-scale production operations.
In short, the PF1010 and PF1214 are generally larger than the PF1007 in terms of specifications, output, and power. Your choice should be based on the expected hourly/daily tonnage, the maximum particle size of the raw material, and the overall budget (including equipment purchase cost and long-term operating energy consumption).
