Sand and gravel powder selection machine is a device used for grading and screening sand and gravel materials, mainly used to meet the requirements of products with different particle sizes. It uses a sieve or airflow to classify and screen materials, separating sand and gravel of different particle sizes into different areas.

Structure and Working Principle

The sand and gravel powder selection machine mainly consists of the following parts:

Shell: including ash hopper, feeding hopper, and bent pipe, etc., equipped with guide vanes, buffer plates, and air seals inside for easy maintenance.

Rotating part: including the rotor and main shaft bearings, the rotor rotates through the transmission part, usually consisting of a feeding tray, horizontal and vertical partitions, upper and lower shaft sleeves, and connecting plates.

Transmission part: The main shaft and bearings are installed inside the main shaft sleeve, using thin oil lubrication and sealing measures.

Lubrication system: responsible for lubricating the spindle and bearings to ensure the normal operation of the equipment.

Its working principle is to classify and screen materials through a sieve or airflow. After entering the powder selection machine, the material is separated by the screen or airflow. Larger particles are left on the surface of the screen or collide with the guide blades before falling, while smaller particles fall into the collection bin below through the screen or airflow. By adjusting the rotor speed, it is easy to adjust the product fineness.

Application scenarios and advantages

The sand and gravel powder selection machine is suitable for the construction industry and road construction fields, and is used to produce sand and gravel aggregates of different particle sizes and densities to meet the different needs of construction and road construction.

Its advantages include

Good separation effect: using air suspension and centrifugal force, the separation effect is excellent.

Simple structure and easy maintenance: The equipment has a simple structure, is easy to maintain, and can operate stably for a long time.

High quality of finished products: can be adjusted according to needs to meet different product requirements.
