Sand Making Machine: Core Equipment for Efficient Production of High-Quality Sand and Gravel

Sand making machine (vertical shaft impact crusher) is a machine that specifically crushes rocks, ores, and other raw materials into sand particles. It is primarily used to produce fine-grained artificial sand, which can replace natural sand in construction, road, bridge, and other projects.

Why Choose a Rich Mechanical Sand Making Machine?

Rich Machinery's sand making equipment offers numerous advantages in performance and design:

High-efficiency production: The deep-cavity rotor design increases material throughput by approximately 30%. The new impeller optimizes material flow, enabling a single unit capacity of up to 650 tons/hour.

Versatility: Combines fine and coarse crushing, resulting in cubic, uniformly shaped finished products with low flake content.

Flexibility: Supports both "rock-on-rock" and "rock-on-iron" crushing modes to accommodate materials of varying hardness.

Environmentally friendly: Self-circulating airflow within the vortex chamber and dust control devices reduce dust pollution.

Energy saving and consumption reduction: The thin oil lubrication system features automatic maintenance, reducing energy consumption by 10%-40% at the same output.

Cost advantage: The reversible guard plate extends its lifespan and reduces replacement costs by approximately 30%.

Sand making machine structure:

The sand making machine primarily consists of a feed hopper, distributor, vortex crushing chamber, impeller, main shaft, transmission system, lubrication system, and base. 

Popular Sand Making Machine Types

VSI Sand Making Machine: Deep-cavity rotor design provides high throughput, 50% energy savings, and a 20% increase in sand production rate.

HVI Sand Making Machine: Combines sand making and shaping, resulting in superior grain shape, utilizing an optimized impact angle design.

Mobile Sand Making Machine: Available with either an HVI or VSI main unit for on-site operation, improving efficiency and providing flexibility.

The sand making machine utilizes the high-speed impact crushing principle:

The material enters the vortex crushing chamber and is broken up by the high-speed rotating impeller. The material collides with each other, creating a vortex between the impeller and the casing. After multiple impacts and friction, the finished product is discharged from the bottom, where the particle size is controlled by a screening machine.

FAQ

1. How to choose between "rock-on-rock" and "rock-on-iron"?

"Rock-on-rock": Suitable for medium-hard or higher-abrasive materials (such as basalt and granite), resulting in fine grain shape but high fineness. "Rock-on-iron": Suitable for medium-hard or lower-abrasive materials (such as limestone), resulting in high efficiency but significant plate wear.

2. What factors influence sand production rate?

Material properties (hardness, moisture, viscosity, etc.), finished product fineness requirements, feed rate control,Impeller speed, and feed moisture content.
