Product introduction
Jaw crushers reduce material by compression between fixed and moving jaw plates. Compact units are considered where the required duty, feeding method and maintenance access match the machine.
Compact Primary Crushing
Small Jaw Crusher: Compact PEF Model Selection
For small primary crushing duties, compare Zhongji catalog PEF models by maximum feed, discharge adjustment and required hourly capacity. These references help build a shortlist; material, operating duty and site conditions must still be checked before quotation.
INTERNAL REVIEW · ASSET GAP / HOLD
Compare the smaller PEF primary jaw crusher models.
Maximum feed rises from 90 to 210 mm across these catalog references. Match the feed and discharge range first, then check capacity, motor and site space.
| PEF model | Max feed | Discharge range | Capacity | Power | Dimensions L × W × H | Weight |
|---|---|---|---|---|---|---|
| PEF100×150 | 90 mm | 5–20 mm | 0.4–1.8 t/h | 2.2 kW | 615 × 449 × 520 mm | 0.4 t |
| PEF150×250 | 125 mm | 10–40 mm | 1–4 t/h | 5.5 kW | 875 × 750 × 950 mm | 0.8 t |
| PEF250×400 | 210 mm | 20–80 mm | 4–14 t/h | 15 kW | 1108 × 1090 × 1392 mm | 2.6 t |

PEF models shown here are compact primary-crushing references. The catalog also lists PEX fine-jaw configurations; do not treat them as interchangeable primary machines. Send material, maximum feed, required product size, hourly capacity, operating hours, voltage and available installation space. See the main Jaw Crusher page for the wider primary range.
Applications
Selected quarry stone, hard or medium-hard rock, mineral samples and small material preparation duties after the working condition is reviewed.
Working principle
The eccentric drive moves the swing jaw toward and away from the fixed jaw. Material is compressed and leaves through the lower discharge opening.
Practical Advantages
Why buyers consider a compact jaw crusher.
Compact arrangement
Easier to plan where site space and upstream feeding are limited.
Compression crushing
A familiar primary crushing principle for many rock and mineral duties.
Wear-part planning
Jaw plates and related parts can be discussed with the confirmed model.
Local service access
Maintenance space and available local tools can be considered during selection.
Factory model checking
Selection is reviewed against material, feed, output and capacity before quotation.
Spare parts
Typical discussions include jaw plates, cheek plates, toggle-related components and bearings. Exact part numbers require the confirmed model and drawing version.
Before quotation
Send material, maximum feed size, output size, capacity, location, voltage and whether the buyer is an end user or distributor.
Selection boundary
A compact machine should not be selected only because it is easier to transport. Required duty and continuous operating conditions remain the priority.

Watch Workshop VideoFAQ
Before choosing a small jaw crusher.
What information is needed?
Material, maximum feed size, output size, required capacity, country, voltage and site feeding method.
Can it process hard stone?
Jaw crushing is commonly considered for hard and medium-hard material, but abrasiveness and actual reduction duty must be checked.
Are spare parts available?
Parts can be checked after the exact model and drawing version are confirmed.
When should I consider a larger jaw crusher?
A larger primary crusher may be required when the feed size, continuous operating duty or capacity is beyond the compact machine range.
