The price of soil and rock separator

Separating soil and rock is an important part of the process of crushing stone. Although it is an auxiliary process, it can determine the value of sand and gravel. With the acceleration of economic development, the demand for the use of sand and gravel in various industries has increased, while the quality The requirements are becoming more and more stringent. For example, the content of mud should not be greater than how much, the content of stone powder should not be greater than how much, what is the size of the particle size, and how many grades are required. With sand and gravel requirements, the earth-rock separator and the mud-rock separator can play a great role.

The quality of the gravel without stone powder and soil is of high quality and high value

Introduction to classification of soil and rock separators

In actual production, most users know that vibrating screens are used for soil and rock separation, but in fact, in mining machinery and equipment, there is more than one type of vibrating screen that can achieve For the separation of soil, rock and mud, lets look at other classifications below.

1 Vibrating feeder

Vibrating feeder is used for the initial screening and is equipped with the vibration feed of the screen bar. The feeder can simply separate the raw materials of the mixed soil and rock, the soil that does not need to be crushed in the raw materials can be transported aside, and the large stones that need to be crushed are fed to the jaw crusher.

Vibrating feeder is generally located before coarse jaw crushing

Vibrating feeder uses a pair of vibration motors with exactly the same performance parameters as the excitation source. When the vibrating motor rotates in the opposite direction at the same angular velocity, the inertial force generated by the eccentric mass is repeatedly superimposed or offset in a specific phase, thereby generating a huge synthetic exciting vibration force, so that the trough is periodically forced on the support spring Vibrate, and use this vibration as the power to bring the animal material to slide and throw on the trough, so that it will continue to move forward to complete the feeding process. When the material passes through the screen on the trough, the soil and fine-grained materials are permeable The gap between the screen bars falls down to achieve the function of pre-screening, which can improve the coarse crushing capacity.

2 Tumbler screen

The main structure of the tumbler screen is the screening cylinder, which is composed of A combination of multiple round-shaped screens. This machine mainly uses the principle of rolling conveyance. When the material enters the drum, due to the tilt and rotation of the drum, the material on the screen surface is constantly turned and rolled, and passes through the classification from top to bottom. The screen is separated out. The drum support adopts an integral through-shaft structure, which runs smoothly and has low noise. According to the needs of screening, it can adopt a fully enclosed structure or an open structure.

Drum screen

The drum screen is very adaptable to materials. Through continuous movement, the clay and stone in the materials that are difficult to separate and clean such as damp and clay are separated to obtain a better cleaning effect. Among them, all The closed structure is easy to seal and collect dust without pollution.

3 circular vibrating screen

The circular vibrating screen is used for the screening after the second stage of crushing, mainly for the classification of the finished material The machine is composed of the bottom frame of the sieve box, screen vibrator, damping spring device, etc., and adopts a cylindrical eccentric The shaft exciter and the partial block adjust the amplitude. The material on the screen is subjected to the impulse transmitted by the screen box on the inclined screen surface to produce continuous throwing motion. When the material meets the screen surface, the particles smaller than the screen hole are passed through the screen. So as to achieve classification.

The circular vibrating screen can thoroughly screen the stone to the users requirements, with high screening efficiency, strong and durable, low noise, not easy to block holes and long service life.

4Sand washing machine

Sand washing machine is suitable for the washing of fine-grained and coarse-grained materials, and is used for building roads with sand Sand and gravel are suitable. Through the impact of strong water flow, not only the stone powder and soil in the finished sand and gravel can be removed, but also the water vapor layer covering the surface of the sand grains can be destroyed during the continuous washing and stirring process, so that the finished sand and gravel can be dehydrated faster , It has the advantages of high cleanliness, reasonable structure, low energy consumption and low water saving. It is an ideal equipment for wet mud and rock separation.

Sand washing machine

The four types of debris separators are introduced above. There are dry separation and wet separation. These are very popular in the sand and gravel market. Which one to choose depends on the actual situation. In short, which one to choose No one will step on the pit.
