Washing and screening machines are devices suitable for use in mining and construction sectors. They have a very wide range of use in sand and mineral quarries. They are very effective in separating the desired material from other substances. The material prepared for use is washed with water to separate unwanted materials, then the water is drained to make it ready for use. Through the screening system, materials of different sizes are separated. There are various combinations of washing and screening machines. Depending on the needs, either new or second-hand washing and screening machine is preferred. Washing and screening machines can be stationary in a facility, or they can be chosen in a mobile form consisting of both washing and screening machines that can be moved to the desired location.
These machines carry out the washing and subsequent dewatering processes of natural or crushed materials such as removing dust, dirt, and different particles from the material. They can be in different sizes. The amount of water used increases depending on the level of pollution of the material. The most important performance expected from washing machines is to achieve maximum cleaning with a minimum amount of water. After completing its task, the machine drains the remaining water out through a special drainage channel. Washing machines are used in mineral quarries and sand quarries. Washing machines are divided into 3 main groups: spiral washers, bucket washers, and hydrocyclone washers.
Spiral washers have single and double helix models. They generally provide superior performance in removing washed or mixed materials from water. The spirals carry the material to be cleaned to the center of the trough, causing each piece to rub against each other for effective cleaning. This way, the material is free from unwanted particles such as dust, mud, and clay. While the unwanted materials are carried on top of the machine as the water fills up in the tank, the thick materials are collected together. The cleaned material sinks to the bottom. The spirals push the cleaned material all the way to the outlet, ensuring complete dewatering. It is essential for the spirals to be resistant to wear to obtain long-term efficiency from the spiral washer, so they must be made of polyurethane material.
Bucket washers are used for removing fine materials such as dust, mud, and clay. They ensure maximum cleaning and dewatering efficiency of fine materials while being removed from water almost dry, saving significant time and cost for additional drying. Bucket washers have the flexibility to be adjusted according to both the amount of material to be cleaned and the level of pollution of the material. This option allows the machine's speed to be reduced, reducing friction force, resulting in low wear even on materials prone to extra wear.
These machines provide maximum efficiency in sand washing specifically. While they require a large amount of water to clean the material, they provide minimum water usage by screening and making the dirty water reusable. Hydrocyclone washers have low investment costs and are very easy to use.
Features Required for Washing Machines
Screening machine is used to separate materials such as sand, gravel, coal, and mineral ore according to their sizes. There are various types of screening machines depending on the size of the material to be screened. Horizontal screen, inclined screen, vibrating screen, and cylinder screen are the most commonly used types.
It provides very high screening efficiency since it allows the material to stay on the screen machine longer. These are very powerful machines with elliptical vibration and six-mill roll-driven system. The vibration, speed, and direction parameters of the screening machine can be adjusted. The bearings are oil lubricated, making maintenance very easy. They have high durability driving forces.
It is the most commonly used screening machine. It is a highly demanded machine type that is operated by gravity. Since small particles are drawn along the screen wire surface, it is also very suitable for use as a sand screening machine.
Cylinder screens are used for classifying materials such as quartz, feldspar, talc, calcite, limestone, and dolomite. They are completely enclosed on top. There is no contact with dust at all. It can be adjustable according to the amount of product to be screened. They are economical and easy to maintain. They operate very quietly.
Intensively vibrating screens are primarily used to separate wet or dry sand, gravel, and mineral ores. Vibrating screens can be used as both a stone screening machine and a sand sieving machine. In vibrating screens, the following types are separated: top-driven screen, top-driven stepped screen, grizzly screen, conventional vibrating screen, vibration control screen, fine material screen, vibrating twin screen.
