What is the Difference Between the AT1860 and AT2160?

Both models share an identical three-layer screen configuration, 40T crawler chassis, and 154KW engine. The only difference is screen box width – 1800mm on the AT1860 versus 2100mm on the AT2160 – giving the AT2160 a higher processing capacity for the same feed size and screen aperture range.

How Many Products Can the Screen Produce at Once?

The three-layer screen box can separate feed into up to four sized fractions in a single pass – three from the screen decks and one fines fraction from the under-screen conveyor. The actual number of products used depends on which conveyors are configured to discharge to separate stockpiles.

What is the Minimum Site Size Required?

In operating configuration, the AT1512 requires approximately 20m × 10m of clear working area, including product conveyor discharge clearance and access for a wheel loader. In transport configuration, the plant folds to its road-legal envelope. No concrete apron or permanent access road is needed – compacted gravel or quarry floor is sufficient for the 63T crawler […]

Can the Plant Run on Grid Power Instead of the Generator?

Yes. The AT1512 supports full-electric drive via external grid connection in addition to the standard 550KW diesel generator. In grid-connected mode, the generator is bypassed entirely. This configuration significantly reduces fuel cost and noise on permanent or long-term sites where grid power is available.

How Often do the Hammers Need to be Replaced?

Hammer life depends on material hardness and abrasiveness. On clean limestone, high-chromium alloy hammers typically run 300–500 hours before rotation or replacement. On more abrasive material such as coal mixed with shale, expect 150–250 hours. The crusher housing opens hydraulically, allowing a two-person crew to rotate or replace all hammers within a standard shift.

What Materials are NOT Suitable for this Plant?

The heavy hammer crusher is designed for soft-to-medium hardness material with compressive strength up to approximately 200 MPa. Hard abrasive rock such as granite, basalt, quartzite, and siliceous river pebble causes rapid hammer and liner wear at unacceptable cost per tonne. For hard rock primary crushing, the Crawler Jaw Crusher Plant or Crawler Cone Crusher […]

What is the Difference Between a Heavy Hammer Crusher and an Impact Crusher?

Both use impact to fracture material, but the heavy hammer crusher is specifically designed for single-stage coarse-to-fine reduction at high feed sizes – accepting material up to 600mm and producing a finished product in one pass. A conventional impact crusher typically handles pre-crushed feed below 400mm and is optimised for particle shape at lower reduction ratios. […]

Is Full-electric Operation Available on all Three Models?

Yes. All three THP models support full-electric drive via an external power connection in addition to the standard diesel-generator configuration. In full-electric mode, the on-board generator is bypassed and the plant runs entirely from grid supply. This is the preferred configuration for permanent or semi-permanent installations in regions where grid power cost is significantly lower […]

What Liner Materials are Available?

Standard liners are high-manganese steel (Mn18Cr2), suitable for most quarry applications. For highly abrasive feed such as quartzite or siliceous river pebble, we offer premium high-manganese-molybdenum alloy liners with approximately 30–50% longer service life. Liner selection is confirmed at the order stage based on material sample hardness and silica content.
