The three-layer vibrating screen is a rotary vibrating screening equipment manufactured by Longjun Machinery, designed for industrial grading and filtration operations. This device integrates three independent sieve layers, enabling simultaneous separation of a single material into four distinct particle size fractions in one pass. It supports continuous production processes and is compatible with granular, powdered, and slurry materials across various industrial applications.
The equipment operates with a three-dimensional vibration pattern, combining horizontal, vertical, and inclined motions to enhance material movement across the screen surfaces. This design facilitates consistent material distribution and improves separation efficiency compared to single-plane vibration systems.
The three-layer vibrating screen operates at a vibration frequency of 1420 times per minute. It features an adjustable deflection block angle that allows operators to modify vibration characteristics based on material properties and screening requirements. Rubber ball cleaning systems are integrated into each layer to prevent screen clogging and maintain consistent throughput during extended operation.
The equipment incorporates a patented mesh mounting system that reduces screen replacement time to 3-5 minutes per layer. This design minimizes production downtime associated with routine maintenance and screen changes, supporting uninterrupted commercial operations. The mesh structure accommodates various screen sizes to meet different grading specifications.
The entire screening chamber is fully enclosed to prevent material spillage and dust emission during operation. This design contributes to cleaner working environments and reduces material loss. Additionally, the enclosed structure helps contain operational noise, supporting compliance with workplace safety standards. The discharge ports can be adjusted to any direction along the 360-degree circumference, allowing flexible integration with existing production lines.

Pharmaceutical industry: Traditional Chinese medicine powder, Western medicine powder, and pharmaceutical raw material powders
Food industry: Sugar, salt, monosodium glutamate, starch, milk powder, soybean milk, fruit juice, rice noodles, dehydrated vegetables, yeast juice, pineapple juice, fish meal, and food additives
Kiln and ceramics industry: Glass, ceramics, porcelain slurry, grinding materials, refractory bricks, kaolin, quicklime, mica, alumina, and heavy calcium carbonate
Metal and metallurgy industry: Lead powder, zinc oxide, titanium oxide, casting sand, diamond powder, aluminum powder, iron powder, and various other metal powders
This equipment can separate materials into four different particle size fractions simultaneously. The specific particle size range depends on the mesh sizes installed, which can be customized according to individual processing requirements.
With the patented quick-change mesh structure, screen replacement for each layer takes approximately 3-5 minutes, significantly reducing maintenance downtime compared to conventional vibrating screens.
The three-layer vibrating screen is suitable for chemical, pharmaceutical, food, ceramics, and metal metallurgy industries. It can process granular, powdered, and slurry materials across these sectors.
Yes, each discharge port can be independently adjusted to any direction along the 360-degree circumference, allowing flexible integration with different production line configurations and facility layouts.
