VSI Sand Maker for Cubical Concrete Sand 0-5mm Output

For concrete producers, achieving a VSI sand maker for cubical concrete sand 0-5mm output is essential to improve workability and reduce cement consumption. A vertical shaft impactor (VSI) is widely used to convert hard rock into well‑shaped, fine aggregates. Below we explain how a VSI works, what affects output quality, and how OCP Mechanical Company supports your sand production.

1. Why a VSI Is Preferred for Cubical Concrete Sand

A VSI sand maker for cubical concrete sand 0-5mm output uses high‑speed rotor and anvil or rock‑on‑rock impact to break particles along natural grain boundaries. Unlike cone crushers that produce elongated or flaky particles, a VSI generates cubical grains with a low flakiness index – a key requirement for high‑strength concrete.

OCP offers the Type V vertical shaft impactor, designed specifically for fine crushing and sand shaping. Note: Product data are constantly updated; for the latest specifications of Type V, please contact our online customer service.

Typical operating parameters for a VSI sand maker for cubical concrete sand 0-5mm output (for illustration only; actual data subject to continuous improvement):

• Feed size range: 5‑40 mm (closed circuit)

• Rotor speed: 1,400‑1,800 rpm

• Capacity: 80‑250 tph depending on rock hardness

• Output: 0‑5 mm with 80‑90% passing 2.36 mm

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

Many concrete batching plants in Southeast Asia and the Middle East have adopted the Type V VSI, reporting improved slump retention and reduced cement demand.

2. How to Achieve Consistent 0-5mm Output

To get reliable performance from a VSI sand maker for cubical concrete sand 0-5mm output, follow these practical steps:

• Control feed size – Keep feed between 10‑40 mm for best results. Oversize lumps reduce tip life and increase recirculation.

• Use a closed circuit – Pair the VSI with a vibrating screen (3‑5 mm apertures) to return oversize material.

• Adjust rotor speed – Higher speed produces more fines but increases wear. Start at 1,500 rpm and adjust based on your sand gradation target.

• Monitor moisture – Feed should be dry (less than 3% moisture) to prevent blinding on screen media.

OCP’s Type V VSI features a variable frequency drive (VFD) for easy speed adjustment and a rock‑on‑rock chamber that minimizes metal consumption. Many operators find that with proper feed control, a set of tungsten carbide tips lasts 80‑150 hours when processing granite or basalt. Actual wear life varies with rock abrasiveness – please ask our engineers for a site‑specific estimate.

To keep your VSI sand maker for cubical concrete sand 0-5mm output economical, we recommend:

• Pre‑screening fines (below 5 mm) before the VSI to reduce unnecessary tip wear.

• Inspecting the rotor tips every 40 hours.

• Keeping a spare set of tips and feed tube in stock.

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