Introduction
A portable screener, also known as a portable screening plant or portable vibrating screen, is a mobile equipment used in various industries to separate and classify materials.
The equipment is designed to be easily transported and set up at different working sites, providing flexibility and efficiency in screening operations.
In river sand gravel separation applications, it is ideal equipment for processing capacity less than 100 tons per hour.
Working principle
Raw materials are loaded to the hopper by excavator or wheel loader. If it is river sand and gravels, the large rocks should be separated before loading, because it will have great impact with the top screen mesh, which reduces the service life.
At the bottom of the loading hopper, there is a belt conveyor for feeding, frequency inverter control panel can control the feeding speed.
When materials are sent to the vibrating screen, which is normally installed with an angle 12 to 22 degrees, separation starts.
During the vibrating process, the large size of material will stay on the top while the small and fine size material pass the screen mesh to the bottom to get different sizes of materials.
Each layer of the screen mesh comes to a collection hopper to different belt conveyors. Thus the materials is separated to different groups.
