The Enduring Legacy of the Pioneer Crusher 20×36: A Workhorse of Aggregate Processing
In the demanding world of aggregate production and mining operations, reliability and robust performance are non-negotiable demands placed upon primary crushing equipment. Among the machines that have earned legendary status through decades of dependable service stands the Pioneer Crusher Model 20×36. This specific jaw crusher configuration represents a cornerstone design within Kolberg-Pioneer's (KPI-JCI) long history of engineering excellence.
The Significance of "20×36"
Emërtimi "20×36" immediately tells seasoned operators and plant managers what this machine offers at its core: një matje e hapjes së ushqimit 20 inches by 36 inç (508 mm x 914 mm). This substantial opening allows the Pioneer 20×36 to accept large run-of-mine rock directly from haul trucks or loaders – a critical capability for efficient primary crushing circuits handling hard rock like granite, bazalt, shkëmb kurth, or abrasive quartzite.
Built for Durability and Demanding Service
What truly defines the Pioneer 20×36 isn't just its size; it's its renowned construction:
1. Heavy-Duty Frame: Built around massive structural steel plates and reinforced ribs, the frame provides exceptional rigidity essential for absorbing immense crushing forces without distortion.
2. Vdes nofulla e kthyeshme e manganit: Utilizing thick manganese steel plates on both the stationary and movable jaws ensures extended wear life under punishing conditions.
3. Overhead Eccentric Shaft: The robust shaft assembly drives the pitman arm assembly with precision.
4. Kushinetat sferike me rul: Large-diameter bearings are employed at critical points (like the eccentric shaft) to handle high radial loads reliably over long periods.
5. Cilësimi i rregullueshëm i shkarkimit: A key feature is its simple yet effective toggle system for adjusting the closed-side setting (CSS). Operators can quickly set output size without complex procedures.
Performance Characteristics
While specific tonnage depends heavily on feed material characteristics (fortësi, gërryes), moisture content, feed gradation/size distribution, and CSS setting:
The Pioneer 20×36 typically handles capacities ranging from approximately 75 ton në orë (TPH) up to around 250 TPH under optimal conditions.
Its maximum recommended feed size is generally around 18 inç.
Its adjustable CSS allows producing product sizes suitable for feeding secondary crushers or screening circuits.
