# Polyurethane sieves

## Polyurethane VS metal

Mechanisms designed for screening coal, rocks, various ores, gravel, etc., were created from metal. They worked with a lot of noise, from what was called "the screens". To work on sorting the companies that make it difficult. The search for an alternative material that would reduce noise effects has led to the creation of polyurethane screens. That is the kind used in Europe.

Why the choice fell on this material it becomes clear if to understand its features.

Get PU from petroleum. It does not harm the environment, does not cause allergic reactions in humans. Therefore widely used in food and light industry, and medicine.

Unlike steel products, polyurethane sieves have a long service life exceeding that of metal analogues in 10-20 times. Run virtually silent.

Products are not deformed under the influence of low and high temperatures, can operate in a wide temperature range from -60°C to +100 °C.

They are easy to maintain, because debris and filtered parts do not adhere to the surface. To clean the item very easy and convenient.

Material not subject to corrosion, so it can be used in salt water and other corrosive liquids. Not deformed due to the weight and blows.

### What made polyurethane sieve

Polyurethane made many parts for industrial applications. Each requires a certain format of the source raw material, therefore producing PU rigid, soft, foam, integrated, and sheet. Latest and used to create screens for screens. It has a high density, good resistance to tear and ability to quickly restore the initial form. And yet, regardless of the operating conditions, prevents the appearance of fungi and mold.

It is important to remember that one should avoid contact of the sieves with acetone and chlorine. Given the characteristics of the PU sheet and correct operation, prolong the service life of devices for screening of coke, sand, slag, etc.

### How to choose the right sieve

Like any product, polyurethane screens has certain criteria due to the challenges they face. So pay attention to the size and shape of cells. You can order ready-made models:

- with a circular cross section (hole size varies from 0.5 cm to 8 cm);
- slit (slit width 0.5 mm);
- square section (size of hole in between 0.3 cm - 8 cm).

Manufacture custom samples according to your drawings. If necessary, develop a model according to the specified requirements. Prepare a sieve that will cope with the task of working on the screening of mixtures in dry form or in liquids.

Constructs used in screening plants are composed of modules that provide promotion mix, and tumbler screening cards. The size of the latter is determined by the dimensions of the screen box.

The cards are held together by special locks. With the wedge shaped modules are connected in a way. This fixation allows you to quickly change a faulty part without having to completely dismantle and not using a special set of tools.

Using polyurethane sieve for screens, collected in a section of patterned, guaranteed to provide production without downtime and loss of revenue.

Worrying about the durability of our products and their high quality, have relied on European raw materials. Today we use several grades of polyurethane that are obtained from manufacturers in Italy, the UK, France and Germany. We also signed a supply contract from Australia.

The material meets the internal standards of Ukraine and international norms.

It is possible to order sieves transparent, black or colored material. The color palette is diverse. Use non-toxic dye. Color due to embedded in the polyurethane UV rays, does not fade. To work in the color setting will be much more pleasant.

### Individual conditions of payment and prompt delivery

We are interested in a long cooperation and sympathetic to each client. We offer favourable payment terms until the deferred payment. All the nuances can be confirmed by the representative of the company individually.

Since the plant is located in the river, do not experience problems with logistics. Regardless of the amount of the order and the distance of the destination guarantee a prompt delivery to any region of the country convenient for the buyer way.
