Granite Manufactured Sand Washing Plant 150 tph Low Fines

For producers of high‑quality concrete sand, a granite manufactured sand washing plant 150 tph low fines removes excess ultrafines (below 0.075 mm) while retaining valuable fine aggregates. Granite is hard and abrasive, and its manufactured sand often contains more than 15‑20% fines after crushing. A properly designed washing plant helps meet concrete specifications (typically <10% passing 0.075 mm) without losing yield. Below we explain the key components and how OCP Mechanical Company supports efficient sand washing.

1. Why Washing Is Essential for Granite Manufactured Sand

A granite manufactured sand washing plant 150 tph low fines typically includes a sand washer, hydrocyclone, dewatering screen, and water recycling system. Granite VSI sand often carries excessive fines due to the high‑energy impact crushing process. Washing removes these fines, improving the sand’s fineness modulus and reducing water demand in concrete.

OCP offers the Type W sand washing plant, integrating a bucket wheel or screw washer, hydrocyclone cluster, and a dewatering screen. Note: Product data are constantly updated; for the latest specifications of Type W, please contact our online customer service.

Typical equipment for a granite manufactured sand washing plant 150 tph low fines (for illustration only; actual data subject to continuous improvement):

• Sand washer: Type S screw washer (single or double shaft) or bucket wheel

• Hydrocyclone cluster: 2‑4 cyclones (150‑250 mm diameter)

• Dewatering screen: 1,500 x 4,500 mm with polyurethane media

• Water pump and recycling tank (clarifier optional)

The above values are for illustration only. OCP continuously improves its products. Contact our online team for the most current data sheet.

Many aggregate producers in Southeast Asia and South America have adopted this configuration, reporting final sand with 5‑8% fines – suitable for high‑strength concrete.

2. How to Achieve Low Fines While Minimizing Water Use

To run a granite manufactured sand washing plant 150 tph low fines economically, focus on fines recovery and water recycling:

• Use a hydrocyclone – It separates fines more efficiently than a screw washer alone. Adjust the vortex finder and apex to control cut size (typically 0.075 mm).

• Recycle water – Install a thickener or clarifier to settle silt and reuse up to 90% of process water.

• Monitor feed solids – Keep feed slurry density between 20‑30% solids for optimal cyclone performance.

• Inspect screen media – Polyurethane panels last longer than woven wire and reduce blinding.

OCP’s Type W plant features a modular design with variable frequency drives on pumps for easy adjustment. Many operators find that a properly tuned hydrocyclone recovers 90‑95% of sand above 0.075 mm while discarding ultrafines. Actual recovery depends on feed gradation and pressure – please ask our engineers for a site‑specific estimate.

To keep your granite manufactured sand washing plant 150 tph low fines running smoothly, we recommend:

• Checking cyclone wear (ceramic liners recommended) every 200 hours.

• Cleaning the water recycling tank weekly to prevent silt buildup.

• Keeping a spare set of screen panels and cyclone apexes in stock.

As a direct‑selling manufacturer, OCP provides factory pricing on wear parts and can ship to major ports worldwide within 15‑20 days.
