PEX 300x1300 Fine Jaw Crusher for Andesite Crushing
The PEX 300x1300 fine jaw crusher takes a 250 mm maximum feed and is rated 30-105 t/h on a 55 kW motor at a 25-60 mm outlet setting. Baichy builds the PEX 300x1300 fine jaw crusher as the fine crushing stage of an andesite line, behind a primary jaw that has already brought quarry rock below 250 mm.
What Does the PEX 300x1300 Fine Jaw Crusher Do in an Andesite Line?
The PEX 300x1300 fine jaw crusher reduces andesite below 250 mm to a 25-60 mm discharge band by compressing rock between a fixed jaw and a moving jaw, driven by an eccentric shaft.
Andesite runs 5-6 on the Mohs scale at a uniaxial compressive strength of 80-200 MPa that varies significantly by quarry, so the fine stage has to transfer crushing force rather than rely on rotor speed. Baichy publishes that its compression-type jaw crushers consume less unit energy and suit high-hardness rock better than an impact crusher, which is why a fine jaw is specified on abrasive andesite.
Feed sent to an impact crusher instead moves the operating cost into rotor wear: Baichy's Indonesia andesite selection guide budgets blow bar life at 300-800 hours in andesite. The PEX 300x1300 fine jaw crusher carries high manganese steel jaw plates and a deep crushing chamber, so its wear surface is a fixed and a moving plate rather than a rotating assembly.

The table is Baichy's published PEX fine jaw crusher series, which spans a 120-250 mm maximum feed, 15-55 kW motor power and 5-105 t/h capacity. The PEX 300x1300 fine jaw crusher is the largest model in the series, with a 300x1300 mm feed opening and a 2000x2320x1730 mm overall dimension.
The PEX range is the fine-crushing subpision of the PE jaw series, and its deep cavity chamber prolongs material residence time in the crushing zone.
How Do You Size a PEX 300x1300 Fine Jaw Crusher for Andesite?
Size the PEX 300x1300 fine jaw crusher from three numbers: the largest lump in mm reaching the fine stage, the target product top size in mm, and the required output in t/h. A 250 mm maximum feed and a 25-60 mm outlet range fix the working window of the PEX 300x1300 fine jaw crusher.
Capacities in the PEX table are quoted on a limestone basis, and Baichy's Indonesia andesite selection guide applies a 0.7-0.85 derating factor to capacity when the feed is andesite, which is harder and denser than limestone. At the mid-point factor of 0.75, the published 105 t/h top of the PEX 300x1300 range becomes about 79 t/h (105 t/h x 0.75), and that derated figure is the number to carry into an andesite contract; the guide works the same factor through a PF1315 example.
Feed above 250 mm has to be reduced first: the PE600x900 jaw crusher accepts a 500 mm maximum feed and discharges at a 60-125 mm outlet adjusting range, inside the 250 mm feed window of the PEX 300x1300 fine jaw crusher.
Andesite Crushing Circuit with the PEX 300x1300 Fine Jaw Crusher
An andesite crushing circuit places the PEX 300x1300 fine jaw crusher between a primary jaw and a YK vibrating screen, fed by a vibrating feeder and linked by belt conveyors that return screened oversize to the fine jaw in closed circuit.
In Indonesia, andesite is quarried for railway ballast and road construction, and Baichy's Indonesia andesite selection guide routes measured strengths above 200 MPa or high SiO2 content to a cone crusher instead. A Symons cone crusher follows the fine jaw wherever the market needs fractions below the 25-60 mm jaw discharge.
Where the deposit is scattered and the plant has to move, Baichy's project record includes a 400 tph andesite mobile portable crusher plant in Indonesia, and a wheel-mounted plant carries the same fine crushing duty without a fixed foundation.

FAQ: PEX 300x1300 Fine Jaw Crusher for Andesite
1. What is the capacity of the PEX 300x1300 fine jaw crusher?
The PEX 300x1300 fine jaw crusher is rated 30-105 t/h at a 25-60 mm outlet setting on a 55 kW motor. On andesite, apply the published 0.7-0.85 derating factor before a figure is written into a contract.
2. What is the maximum feed size of the PEX 300x1300 fine jaw crusher?
The maximum feed size of the PEX 300x1300 fine jaw crusher is 250 mm. Larger rock goes to a primary jaw first: the PE600x900 jaw crusher takes a 500 mm maximum feed and discharges at 60-125 mm, inside the feed window of the fine jaw.
3. Can the PEX 300x1300 fine jaw crusher process andesite?
Yes. Andesite runs 5-6 on the Mohs scale at 80-200 MPa, and Baichy publishes that compression-type jaw crushers suit high-hardness rock better than impact crushers. Above 200 MPa or with high SiO2 content, the guide routes the feed to a cone crusher.
4. How is the discharge of the PEX 300x1300 fine jaw crusher adjusted?
Outlet size across the PEX range is adjusted by gaskets or a hydraulic device, and the published outlet range for the PEX 300x1300 fine jaw crusher is 25-60 mm. Outlet adjustment sets the product top size and does not change the feed window.
5. What does a PEX 300x1300 fine jaw crusher cost?
The PEX 300x1300 fine jaw crusher is quoted per project, because jaw plate grade, drive configuration and control level change the price of one model size. Send the andesite feed size in mm, target output in t/h and product top size in mm for a quotation.
