Primary Jaw Crusher
Aluminum ore primary crusher selection starts from the largest lump in the run-of-mine feed, not from the target tonnage. Baichy publishes jaw crusher models for this duty from 5 to 1,100 t/h, with feed openings from 250x400 mm to 1500x1800 mm and motors from 15 kW to 280 kW.
What Equipment Does Primary Crushing of Aluminum Ore Require?
A jaw crusher fed by a vibrating feeder is the published first choice for primary crushing of aluminum ore. The PE series covers a feed size of 125 mm to 1200 mm and is used for both coarse crushing and fine crushing.
Aluminum ore reaches the plant as bauxite, kaolin and alunite, at a published hardness of Mohs 1-3. Clay minerals make bauxite primary crusher duty harder than that hardness range suggests, because the ore adheres to liners and bridges in the chamber.
Why a Jaw Crusher and Not an Impact or Hammer Crusher
A jaw crusher reduces the ore between a moving jaw and a fixed jaw, and its published cavity is deep with no dead zone, which raises feeding capacity and output on wet, clay-bearing aluminum ore.
• Adhesion and clogging — for aluminum ore with high water and mud content, the published answer is a double roller crusher with self-cleaning toothed rollers and a hydraulic adjustment device.
• Compressive strength — the jaw crusher accepts material up to 320 MPa; the impact crusher is published for a side length not exceeding 500 mm and a compressive strength not exceeding 350 MPa.

PE Jaw Crusher Models Published for Aluminum Ore Coarse Crushing
PE jaw crusher capacity on aluminum ore is published at 5-1,100 t/h across the range. Throughput per model moves with ore hardness, feed size and outlet setting, so the t/h figures below are published values, not fixed output.
| Model | Feeder Opening Size (mm) | Max. Feeding Size (mm) | Outlet adjusting Size (mm) | Capacity (t/h) | Motor Power (kW) |
|---|---|---|---|---|---|
| PE250×400 | 250×400 | 210 | 25–60 | 5–20 | 15 |
| PE400×600 | 400×600 | 350 | 40–90 | 15–60 | 30 |
| PE600×900 | 600×900 | 500 | 60–125 | 90–180 | 55 |
| PE750×1060 | 750×1060 | 630 | 60–150 | 110–380 | 110 |
| PE900×1200 | 900×1200 | 750 | 95–165 | 220–450 | 132 |
| PE1200×1500 | 1200×1500 | 1020 | 150–300 | 400–800 | 220 |
Numbers are reproduced as published; headings are re-typeset from the source table's row labels, whose Overall Dimension (mm) column is omitted. The PE750x1060 jaw crusher page carries the model sheet.
How Do You Size an Aluminum Ore Primary Crusher?
Size an aluminum ore primary crusher from three numbers: the largest lump in mm, the required tonnage in t/h, and the product size the next stage accepts.
• Largest lump — published maximum feed size runs from 210 mm on the PE250x400 to 1,020 mm on the PE1200x1500; 500 mm is 83% of the 600 mm opening on the PE600x900.
• Required tonnage — Baichy maps under 100 t/h to the PE250x400 and PE400x600, 100-300 t/h to the PE600x900 and PE750x1060, and above 300 t/h to the PE900x1200 and the C Series.
• Outlet setting — the outlet adjusting size runs from 25-60 mm on the PE250x400 to 150-300 mm on the PE1200x1500, pushing the coarse product into the 50-150 mm band used for road cushion filling.
What Drives Wear and Energy Cost in Aluminum Ore Primary Crushing?
Wear parts and installed power set the operating cost of aluminum ore primary crushing more than purchase price does.
• Wear material — Baichy publishes high-chromium alloy and tungsten carbide composite parts on key components, with wear-part lifespan stated as more than 30% longer. Jaw plates are published as high-manganese steel.
• Energy — the same source publishes single-machine energy saving of 15% to 30% and system energy saving of more than double, against an unstated baseline.
• Adjustment — the gasket-type outlet device is published as reliable and convenient, with a wide adjustment range for ore grade changes between benches.
FAQ: Aluminum Ore Primary Crushing
1. What is the primary crusher for aluminum ore?
A jaw crusher is the published first choice for primary crushing of aluminum ore, and the PE series covers a feed size of 125 mm to 1200 mm. Aluminum ore reaches the plant as bauxite, kaolin and alunite at Mohs hardness 1-3.
2. What is the maximum feed size of a PE jaw crusher on aluminum ore?
The published maximum feed size runs from 210 mm on the PE250x400 to 1,020 mm on the PE1200x1500. In between: 500 mm on the PE600x900, 630 mm on the PE750x1060 and 750 mm on the PE900x1200.
3. How much does an aluminum ore primary crusher cost?
No price is published for the PE range. A quotation moves with ore properties, feed conditions, required capacity in t/h and site conditions. Send the largest lump in mm and the target tonnage for a model recommendation with a flowsheet.
4. Does sticky aluminum ore change the crusher choice?
Yes. Clay minerals and varying moisture make aluminum ore adhere and bridge, so the published answer for high water and mud content is a double roller crusher with self-cleaning toothed rollers and a hydraulic adjustment device.
5. What comes after the primary crusher on an aluminum ore line?
The published coarse crushing line runs a vibrating feeder, jaw crusher, vibrating screen, feeder and conveyor belt, with a finished size mostly between 50-150 mm for road cushion filling.
