Wave-roller screen (mud and stone separator

The wave roller screen is driven by multiple shafts in multiple sections towards the discharge port, and the shafts are interlinked with each other, so it is also called a multi-shaft interlinked roller screen (there are also non-interlinked types). It is a professional separation and screening equipment designed for the coarse and fine separation of high-moisture, high-viscosity, large and complex materials. For various coarse and fine material separation conditions such as mud and stone separation, soil and stone separation, sand and stone separation, large and small stone materials and stone powder separation, coal screening, construction waste and solid waste separation, and old garbage separation, we design different wave-roller screens according to the different application environments of users. When the particle size of viscous and wet materials is 10mm, the screening efficiency can reach over 85%, and when the particle size is 30mm, the screening efficiency can reach over 90%.

The working principle of the wave roller screen

1. By utilizing the principle of sinusoidal wave, the materials on the screen layer are disturbed, loosened and separated. The relative space organically combined between the circular roller and the cutter head forms screen holes, which are combined into a screen grate to screen the materials.

2. The number of screen shafts and the shaft spacing (screening gap) can be flexibly selected according to the processing capacity requirements.

3. The rotation direction of the screen shaft is the same as the movement direction of the material: on the one hand, it saves the power for the screen plates to rotate and reduces the power consumption of the motor; On the other hand, it avoids the occurrence of adverse phenomena such as blockage, accumulation and clogging of dead coal, which is more conducive to screening. Under the same screening area, the screening efficiency is higher and the processing capacity is greater.

4. Strong adaptability to sieve hole size: By precisely adjusting the shaft spacing and the size of the spacer sleeve, the sieve hole size can be strictly controlled within the range of 0.6 to 30mm, and the sieve hole size can be determined as needed to adapt to different particle size classifications. This machine is highly flexible and adaptable. According to the working conditions and the characteristics of the sorted raw materials, it adopts a one-to-one customization service. For different materials and screening gaps, the structure of the model is designed differently to meet the needs of users.

Features of the wave roller screen

1. It is applicable to particle size classification of ≥0.6mm and above.

2. It has a large processing capacity per unit area and operates stably and reliably.

3. It is applicable to various types of materials to be screened. It can handle materials with high moisture content and high viscosity.

4. High screening rate, no jamming or clogging of screen holes, and continuous and smooth material passing through the screen.

5. Good environmental protection performance. The whole machine adopts a fully enclosed structure, featuring no vibration and low noise.

6. Vibration-free, compact in size, and more convenient for installation and maintenance.

This machine is widely used in: screening and feeding before crushers in stone quarries, the cement and building materials industry, mineral processing plants, coal mines and other industries, underground and above-ground raw coal screening and transportation, coal gangue, coke and blue carbon screening in coal yards, separation of construction solid waste and decoration waste, separation of old waste, etc.
