Sand Making Machine | Leimeng Sand Production Solutions

1. Introduction: The Critical Role of Sand Making Equipment in Construction and Infrastructure

As global construction and infrastructure projects continue to expand, manufactured sand is playing an increasingly vital role as a replacement for natural sand. In sectors such as concrete production, highway and bridge construction, airport projects, and real estate development, high-quality manufactured sand is essential to ensure engineering quality.

At the heart of manufactured sand production is the sand making machine, a core component of the process. Currently, two major types of sand making machines dominate the market: the VSI Vertical Shaft Impact Crusher and the 2PG Series Double Roller Crusher.

As a leading Chinese sand making machine manufacturer, Leimeng has developed mature technologies and amassed numerous successful project cases involving both types of equipment. We are capable of providing efficient, energy-saving, and customized sand production line solutions for clients in regions such as the Middle East, Africa, and South America.

2. Equipment Principles and Suitable Materials

Leimeng VSI Sand Making Machine

The VSI sand making machine uses a high-speed rotor to throw materials against an anvil or material bed, achieving either “stone-on-stone” or “stone-on-metal” crushing.

Key Features:

• Dual working modes: “stone-on-stone” and “stone-on-metal,” switchable based on material properties
• Ideal for hard and abrasive materials such as basalt, granite, and quartz
• Produces excellent grain shape, widely used in high-strength concrete, dry mortar, and road sand

Leimeng 2PG Double Roller Sand Making Machine

The 2PG series double roller crusher operates on a principle of compression and shearing between two rollers. Under the combined pressure of hydraulic cylinders and springs, material is crushed as it passes between the rollers.

Key Features:

• Adjustable gap between rollers to meet various granularity requirements
• Capable of handling medium-hard, high-moisture, and high-clay-content materials
• Low dust, high reduction ratio, and low energy consumption—ideal for projects with strict demands on finished product rate

3. Grain Shape and Output Comparison

In real-world applications, Leimeng’s 2PG roller crusher demonstrates a clear advantage in finished product yield and particle control, making it especially suitable for large-scale production and energy-conscious projects.

4. Energy Consumption and Operating Costs

VSI Sand Making Machine

The VSI impact crusher has an energy consumption of 2.8–3.5 kWh per ton. Due to its high-speed rotating rotor, it requires significant power input, resulting in relatively high energy consumption. Additionally, energy losses occur during crushing, such as dissipation from high-speed impact and over-crushing of materials, leading to lower energy efficiency.

2PG Double-Roll Sand Making Machine

The 2PG double-roll crusher consumes only 1.7–2.1 kWh per ton, saving 40% in electricity compared to the VSI impact crusher, with significantly improved energy efficiency.

For example, at the same processing capacity of 400 tons per hour:

• The VSI630 (dual-motor) has a total power of 315 kW × 2 = 630 kW.
• The 2PG1510 operates at just 450 kW.

Its low-speed operation (roll speed <15 m/s) reduces energy loss and avoids the energy dissipation caused by high-speed impact, enhancing overall energy utilization.

Additionally, the utilization rate of the roller liner is as high as 88%. The machine adopts solid rollers with solid liners, extending liner life to 800–1200 hours, significantly improving durability.
