High Frequency Vibrating Screen
High-frequency vibrating screen is a screening device specially designed to improve the screening efficiency of fine-grained materials. It is widely used in mining, coal, building materials, chemical industry, and other industries. Compared with traditional vibrating screens, high-frequency vibrating screens improve screening efficiency through high-frequency vibration effect, can accurately separate materials of different particle sizes, and are especially suitable for wet screening and screening of fine-grained materials.
Capacity: 10-500tph
Motor Power: 2.2kW-30kW
Screen Layer: 1-4 available
Screen Materials: Steel, ethoxylate resin
Applications: Mining, quarrying, and so on industries to screen ore, sand, and gravel effectively.
High Frequency Vibrating Screen Overview
A vibrating screen is a kind of mine classification machine for ore, mine, sand, gravel, coal, slurry, etc. which consists of a screen and a vibrator. Generally below 50 mesh for the coarse screen, and 80 mesh for the fine screen. The vibrator is an eccentric wheel that rotates under the drive of the motor, making the sieve frame vibrate. Because of the vibration of the sieve frame, the thicker solid particles are left on the sieve surface when they flow to the sieve surface and are discharged from one end along the sloping surface. The finer solid particles and the mud liquid flow through the sieve hole to the mud pond together.
Vibrating Screen Types
The vibrating sieve can be divided into the mining vibrating screen, light fine vibrating screen, and experimental vibrating screen. It can also be divided into the linear vibrating screen, circular vibrating screen, high frequency vibrating screen, double deck vibrating screen, single deck vibrating screen, and so on.
The vibration screen is widely used in coal and other industries for material classification, mineral washing, dehydration, and sand screening. It is commonly used in mining, coal, smelting, building materials, refractory, light industry, and chemical industries for its high production efficiency, good classification effect, and convenient maintenance.
Advantages
The high frequency screen offers significant application advantages in mineral processing across various materials. For iron ore and limonite, it is utilized for ore concentrate classification by effectively screening out low-grade larger particles, enhancing the concentrate grade by 1% to 3% while simultaneously reducing over-grinding. Under the same concentrate grade conditions, the average granularity of the ore concentrate increases, leading to improved filtration conditions and a reduction in cake moisture content by 0.5% to 1%. In the processing of tungsten, tin, tantalum, and niobium, the high frequency screen can replace or work in conjunction with spiral classifiers and cyclones. This setup markedly reduces high-density material disruptions and enhances dressing efficiency, increasing the return ratio by 10% to 15%. Additionally, in quartz sand processing, it is employed in the scrubbing and screening flow to consistently produce certified products. For metal powder production, it effectively produces metals with particle sizes ranging from -38μm to -351μm (400 to 40 mesh).
✔ High screening efficiency: With high-frequency vibration, fine-grained materials stay on the screen for a short time, and the screening efficiency is significantly improved.
✔ Fine-grained material separation: It can process materials with a particle size of less than 1mm, suitable for the separation of fine materials.
✔ Small footprint: The equipment has a compact structure and saves production space.
✔ Simple operation and convenient maintenance: Reasonable design, easy to operate and maintain.
✔ Multi-layer screening: Multi-layer screens can be set according to needs to improve the processing capacity per unit time.
Structures & Working Principle
Vibrator Screen Structure
The main parts of a vibrating screen are the mainframe, screen, electric vibrators, electric motor, rub spring, and coupler.
Vibrating Screen Machine Working Principle
Vibrating screen uses electric exciter as a vibrating source, the material will be thrown around the screen, at the same time doing forward sports, in order to achieve the screening purpose. Material from the feeder evenly enters into the machine’s feeding inlet, with multilayer sieves to produce various products and unqualified products on the screen or under the screen, then discharging from the outlet respectively. It can be used in the automatic production line.
In the working process, the dynamic performance of the vibrating screen directly affects the screening efficiency and service life. The vibrating screen uses the vibration excited by the vibrating motor as the vibration source so that the material is thrown up on the screen Mesh and moves forward in a straight line Through the multi-layer screen to produce a number of the screen on the screen, screen under the material, respectively from their respective export discharge.
