Product details
Circular vibrating screen (referred to as circular vibrating screen) is the most commonly used multi-layer and efficient vibrating screening equipment in industry. Its core is to vibrate the screen body in a circular (or elliptical) trajectory, allowing materials to jump, roll, and quickly classify on the screen surface.
1、 Basic principles
The motor drives the eccentric block/exciter to rotate at high speed, generating centrifugal force → the sieve box performs circular motion → the material is continuously thrown up and slid forward → fine material passes through the mesh, and coarse material is discharged along the sieve surface, achieving classification/impurity removal/filtration.
2、 Two major types (with completely different appearances)
1. Heavy duty circular vibrating screen for mining (mining/sand and gravel)
Structure: rectangular box, seat/suspended installation, single axis/double axis exciter
Features: Large processing capacity (30-850 t/h), impact resistance, suitable for coarse/medium particle size (0.074-50 mm)
Typical models: YK, YA, YKR series
2. Rotary vibrating screen (fine circular screen/three-dimensional rotary vibrating screen)
Structure: Vertical cylinder, multi-layer screen (1-5 layers), bottom vertical vibration motor
Features: High precision (2-500 mesh), fully sealed, suitable for powder/slurry/fine grading
Material: Carbon steel, stainless steel (food/pharmaceutical), plastic (anti-corrosion)
3、 Core structure (universal)
Screening box: welded high-strength steel plate, main load-bearing structure
Excitation source: eccentric shaft exciter (heavy-duty) or vibration motor (fine type)
Sieve: Multiple layers, different pore sizes, determine grading specifications
Vibration damping spring: isolation and protection foundation
Import and export, rack, transmission device
4、 Main features
High screening efficiency (85% -92%), sufficient material rolling, and less likely to clog the mesh
Multi level grading: 2-6 particle sizes are separated at once
Widely applicable: dry/wet, coarse/fine, powder/particle/slurry can be used
Sturdy structure, low noise, easy maintenance
5、 Application industry
Mining/Metallurgy: Classification of Ore, Coal, and Metal Powder
Building materials/sand and gravel: graded machine-made sand, gravel, and aggregate
Chemical/Pharmaceutical: resins, coatings, traditional Chinese medicine powders, pharmaceutical raw materials
Food: starch, powdered sugar, milk powder, soybeans, salt
Environmental Protection: Construction Waste, Wastewater Treatment, Solid Waste Separation
6、 Simple difference from linear sieve
Circular vibrating screen: trajectory circular/elliptical, strong ejection, good grading, suitable for medium to fine particles/multiple layers
Linear vibrating screen: Linear reciprocating, fast conveying, large processing capacity, suitable for coarse materials/dewatering
7、 Key selection points
Coarse and large chunks, high yield → Choose heavy-duty circular vibrating screen (YK/YA)
Fine powder, multiple grades, food and medicine → Choose stainless steel vibrating screen
Check the particle size, humidity, yield, corrosiveness, and hygiene level of the material

We will uphold the spirit of precision engineering, leveraging its profound technical expertise and end-to-end service capabilities as core drivers.
Working principle: Integrating mechanical, hydraulic, electrical, automation and other technologies, the horizontal shaft is driven by an electric motor to rotate, and the eccentric sleeve is driven by gears to rotate, thereby driving the dynamic cone to make circular oscillations, achieving continuous extrusion and crushing of materials. The crushing chamber is optimized in design, and the crushing effect is not affected by liner wear.

Smelting equipment (blast furnace, converter, electric furnace supporting equipment)
Core positioning: The core equipment for coarse crushing of large materials is mainly used at the front end of the crushing production line to crush large raw materials (with a maximum feed particle size of 1200mm) to ≤ 80mm, laying the foundation for subsequent crushing processes. It is an essential front-end equipment for cement and mining production lines. Working principle: Adopting the principle of squeezing and crushing, the large pieces of material falling between the fixed jaw plate and the moving jaw plate are squeezed and crushed through the reciprocating biting motion of the two jaw plates, achieving coarse crushing processing. It is divided into two types: single elbow plate and double elbow plate. The single elbow plate model has higher production capacity and is suitable for high-yield demand scenarios. Core advantages: simple structure, convenient operation, long service life of wear-resistant parts, large crushing ratio, stable output, suitable for high hardness materials (such as limestone and iron ore), low maintenance cost, suitable for various types of production lines from small to large. Adaptation scenarios: coarse crushing of raw materials in cement production lines, coarse crushing in mining, raw material crushing in sand and gravel yards, coarse crushing in construction waste recycling, etc. Corresponding images (high-definition without watermark, available for direct image search): actual photos of the entire jaw crusher, close-up shots of the jaw crusher feed inlet, jaw crusher mining site, and details of the jaw crusher transmission device.
