How to Solve Common Problems for Screening Process and Why Choose Huatao Polyurethane Screen Panels

In the mineral processing industry, screening efficiency directly determines the production line capacity and product quality. Polyurethane fine screen mesh has become a key component in the screening of ores, coal, silica sand and other materials due to its high wear resistance, impact resistance and excellent elasticity.

However, in practical application, users may face problems such as low screening efficiency and short service life,etc. This article will analyse the root causes of the problem from a technical point of view, and put forward targeted solutions to help enterprises achieve cost reduction and efficiency. And we will also give reasons why you should choose our Huatao Polyurethane Fine Screen Panels?

I. Common Problems and Causes

Screen hole blockage: when the mineral particles have high mud content and high humidity, they are easy to adhere to the screen holes, resulting in a reduction in the effective screening area.

2. Improper setting of vibration parameters (such as amplitude and frequency) of the sieve machine, resulting in the accumulation of materials on the screen surface or insufficient jumping.

3. Insufficient elasticity of sieve mesh: traditional sieve mesh due to material quality problem, can not effectively transfer vibration energy, affecting the particles through the sieve rate.

However at Huatao Group, you can have screen panels made of imported Top quality Lanxess Polyurethane from USA, which will guarantee as least 6 months perfect working condition.

I. Targeted solutions

1. Choose right screen meshes and screening methods according to characteristics of screened materials

When screening materials with fine particles, high moisture content, and a large amount of clay, the materials are prone to adhesion. Especially when the moisture content is more than 5%, the materials need to be dried and dehydrated before screening. If the moisture content is more than 8%, wet screening should be carried out.

2. Adjustment of vibration parameters of sieving machine

For minerals with high density and coarse particle size (such as iron ore), it is recommended to adopt low frequency and high amplitude (vibration frequency of 15-20Hz, amplitude of 4-6mm) to enhance the throwing force of materials;

For fine particles or sticky wet materials, it is recommended to use high frequency low amplitude (vibration frequency 25-30Hz, amplitude 2-3mm), to enhance the penetration rate and reduce the plugging holes.

3. Ask Huatao Group for Customised service

According to the characteristics of minerals (particle size, humidity, hardness) customised screen hole shape (square, slit) and aperture rate, accurately matching the screening needs.

HUATAO Group offers a variety of polyurethane screen plates and is committed to becoming your trusted supplier of high-quality accessories suitable for various screening machines.
