GNR YM1650 — Mobile Washing & Screening Plant (top model)

The GNR YM1650 is the most-preferred model in the range, a mobile wash-and-screen plant delivering 120-180 tph. Thanks to a wide washing screen and a screw, it turns out clean sand of several sizes and types in a single pass. All the washing-and-screening kit is united on a 21,000 kg single mobile chassis, with a feed window of 0-100 mm.

Wide deck, high tonnage

The YM1650 runs the same wash logic as its sibling YM1240 but on a bigger screen and a higher flow, delivering clean sand without choking even at high tonnage:

• Washing screen: water and vibration act together; clay and silt are scraped off the surface and shed.
• Screw: it scrubs the fine sand, overflows the silt-laden water and empties out clean sand.
• Stockpiling: multi-size clean sand is spread by by-product belts across separate stockpiles.

Technical data

Mesh calibre and the delivered gradation are locked in per order once the material is known.

Sand recovery and moisture

Screw-discharge moisture usually sits at 15-30%. The full sand-recovery chain runs like this: screw → hydrocyclone (d50 ~45-150 µm, target ~150 µm in aggregate) → dewatering screen; moisture thus falls to 8-20%, yielding a storable sand that holds a steady mortar/concrete batch. The clay burden is read from an SE (Sand Equivalent) or MBV (Methylene Blue Value) test.

Why the YM1650 is the flagship

YM is washing (screw + washing screen), ME is dry (no washing). Both the YM1240 and the YM1650 wash; capacity and size set them apart: the YM1650 offers a wider screen and 120-180 tph, a longer 13.6 m chassis (YM1240: 10.8 m) and 21 t of weight (YM1240: 18 t). That power-to-size balance is exactly why it sells most. For dry, clean feed the matching machine is instead the GNR ME1650.

Application

Multi-size sand production for the construction and chemical industries, aggregate for concrete batching plants, and washing of river and quarry sand. On off-grid sites it is driven by generator, and its high flow makes it the main sand source of large plants.

Full washing line, one contact

At most rivals the washing line lags; General Makina raises log, bucket-wheel and screw washers with dewatering with one contact that also takes in the batching plant. The YM1650 is engineered as a chain welded onto crushing-screening, with added washers (a log washer on clayey feed) and a batching plant — matched spares, undivided responsibility.
