VSI sand processing machine is the latest type of sand manufacturing machine. VSI sand-making machine is mainly used for construction sand making. It can process all kinds of rocks, sandstone, and pebbles into construction sand of various specifications. Machine-made sand has uniform particle size and high compressive strength, which is far more in line with construction requirements than natural sand or sand produced by ordinary hammer sand machines.

VSI sand-making machine is a popular piece of equipment in the field of artificial sand making and stone shaping. It is specially designed to provide high-quality sand and gravel aggregates for highways, high-speed rail, construction, municipal, hydropower dam construction, and concrete mixing plants.

The VSI sand processing machine utilizes high-speed rotating materials to crush each other and friction between materials. When working, the material enters the crushing cavity of the VSI sand-making machine vertically from the upper part. Under the centrifugal force of the high-speed rotating impeller, the materials interact and collide.

The maximum feed particle size is generally ≤80mm and materials larger than the specified particle size are strictly prohibited from entering the crusher, and the maximum water content of the feed is ≤20%. Generally, the ore from the sand washing machine can directly enter the VSI sand-making machine.

According to the feeding method and crushing form, the D&G MACHINERY sand-making machine is divided into 4 working modes, which are:

Full center feed + stone-on-stone

Fully center feed + stone-on-iron

Center feed accompanied by waterfall feeding + stone-on-stone

Center feed accompanied by waterfall feeding + stone-on-iron

Use Characteristics of Each Work Form

Center Feeding: Make the material obtain the highest kinetic energy (up to 80m/s).

Cascade Feeding: Increases output (up to 10%) without increasing power.

Rock-on-rock: Suitable for crushing materials above medium hardness. The material has a good particle shape and slightly more powder content.

Stone-on-Iiron: It is suitable for crushing materials below medium hardness. The crushing efficiency is high, the cost of wearing parts is also high, and the particle shape of the material is slightly poor.

From the perspective of crushing efficiency, when the working mode is 'central feeding + stone hitting iron', the crushing efficiency of the material is the highest, but the particle shape of the material is slightly worse. From the perspective of material shape, when the working method is 'center feeding + rock-on-rock', the material shaping effect is the best. In addition, according to the different needs of customers, you can choose the working mode suitable for their working conditions.

VSI sand processing machines consist of several key components that work together to achieve efficient and high-quality sand production. Let's discuss the composition of the VSI sand making machine:

Body/Frame: The body or frame of the VSI sand-making machine provides structural support and houses the various components. It is usually made of strong steel construction to withstand crushing forces and vibrations during operation.

Rotor: The rotor is an important part responsible for high-speed rotation inside the sand-making machine. It is usually made of durable materials such as high-grade steel or cast iron. The rotor plays a vital role in crushing the incoming materials and accelerating them to create the necessary impact.

Crushing Chamber: The crushing chamber, also known as the crushing chamber, is where the actual crushing and shaping of the raw material takes place. It is lined with wear-resistant materials such as manganese steel or high-chromium alloy to withstand the abrasiveness of the processed material. The shape and configuration of the crushing chamber can vary according to the desired output specification.

Impeller: The impeller, also known as the feed tube or feed cone, is located in the center of the rotor. It guides the material into the crushing cavity, distributes it evenly, and realizes high-efficiency crushing. The impeller design plays a vital role in controlling the flow and velocity of the material, ensuring optimum particle impact and distribution.

Distribution Cone: The distribution cone, sometimes called a distribution plate or wear plate, sits above the impeller. It helps the material to be evenly dispersed in the whole crushing cavity, ensures uniform wear of the worn parts, and improves the overall crushing efficiency.

Feed Hopper: The feed hopper is the inlet where the raw material enters the VSI sand-making machine. It is designed to accommodate a continuous and regulated material flow, ensuring a constant supply for efficient operation. The size and design of the feed hopper may vary depending on the specific application and material requirements.

Feed Tube: The feed tube, also known as the feed cylinder, connects the feed hopper to the impeller. It guides the material from the hopper to the impeller, controlling the flow and direction of the feed.

Drive System: The drive system is composed of a motor and a transmission mechanism, providing the power and rotational force required to drive the rotor. The motor drives the rotor through a belt or direct coupling to achieve the high-speed rotation required for effective crushing and sand production.

Lubrication System: Equipped with a lubrication system to ensure smooth operation and reduce friction between moving parts. It provides lubrication to bearings and other critical components, extending their life and minimizing wear.

Control Panel: The control panel allows the operator to monitor and control various parameters of the sand-making machine such as feed rate, rotor speed, and product size. It provides a user-friendly interface for efficient operation and adjustment of the machine.

Every component of a VSI sand-making machine contributes to its overall performance and ability to produce quality sand. The precise design and integration of these components ensure optimal crushing, shaping, and efficient operation, making VSI sand-making machines a valuable asset in the construction and mining industries.
