The double-layer banana sieve is mainly used for coal grading, desliming, dehydration and de-intermediation, and also suitable for the screening and grading of other minerals. The double-layer banana screen includes side panels, vibration exciters, motors, belt drives, auxiliary shaft pairs, buffer springs, upper sieve plates, lower sieve plates, excitation beams, upper beams, lower beams, lifting beams, etc. Double-layer vibrating sieve for banana sieve. The upper sieve plate has a large inclination angle, and the lower sieve is basically arranged horizontally. This structure can efficiently process a large amount of feedstock through thin-layer screening. The feed material passes through the upper sieve plate at a high speed to make the powder material get preliminary separation. The material moves at high speed on the sieve plate to separate it into thin layers. Maintenance of banana sieve Before installation, it is necessary to check whether the parts are intact and complete, and

  vibration motor features 1. The vibration force and power are matched properly, the vibration force is large, the body weight is light, the volume is small, and the mechanical noise is low. 2. Because the vibration motor is a strong resistance type vibration instead of resonance, it has a stable amplitude. 3. Large vibration frequency range. The vibration frequency of the electromagnetic exciter is fixed, generally equal to the power step rate, and the vibration frequency of the vibration motor can be adjusted in a wide range by adjusting the speed, and the vibration frequency and amplitude can be arbitrarily selected according to different paths. 4. Affected by power fluctuations, electromagnetic exciters will cause large changes in excitation force due to voltage changes, but this change is very small in vibrating motors.

In the process of disposal, the project department abandoned the conventional factory operation practices and innovated the management model; actively carried out scientific research and innovation, solved a number of stuck technical problems, and formed “sludge screening + sludge conditioning + dewatering reduction + co-processing” The overall technical route of the Qingninghou landfill will eventually achieve the goal of reducing, harmless, and recycling about 330,000 tons of sludge in the Qingninghou landfill.  Although the method of directly transporting the raw mud to thermal power plants...

Stone powder with a particle size of less than 0.08mm in machine made sand can improve the workability of concrete. The gradation and particle size of machine-made sand will obviously affect the working performance of concrete. Reasonable use of superplasticizers can make up for the negative impact of stone powder in machine-made sand. One view is that when the content of stone powder in machine-made sand is between 5% and 10%, the effect on the working performance of concrete is negligible. Another view is that the stone powder in machine-made sand has a positive effect on the strength of concrete. The stone powder in the machine-made sand can fill the pores in the concrete, thereby increasing the compactness of the concrete and improving the strength of the concrete. According to the conclusions of related experiments, the influence of 5 kinds of stone powder content of machine-made sand on the working performance, compressive strength and impermeability of C60 high-strength concre

The banana screen is a vibration grading with a box vibrator and a plurality of different inclined screen faces. The shape of the main box is similar to that of a banana. It is mainly used for the classification of large and medium-sized materials with high fine content, and can also be used for dehydration, de-intermediation, and de-sludge operations. (The fine particles refer to particles with a particle size of less than half the size of the mesh.) The banana screen is designed by injecting a banana-shaped multi-stage working surface on the basis of a linear classifier. There is a larger slope screen at the feed end, followed by a stepwise decrease at a certain number of angles until the discharge opening, the overall screen surface is concave curved. The sloped screen at the feed end allows for more material to pass through the screen surface with higher screening speeds and thinner material delamination. Because the bulk material passes through the steep slope faster, this earlie

The curved vibrating screen is a linear vibrating screen with a box vibrator and multiple screen surfaces with different inclination angles. Because the shape of the screen box is similar to that of a banana, it is also called a banana screen. It is mainly used for the classification of medium and fine-grained materials with high content of fine particles. It can also be used for dewatering, de-intermediation and desliming operations (fine particle size refers to particles whose particle size is less than half of the mesh size). It can carry out dry and wet classification for small and medium particles of coal, coke, ore, gravel, or other materials. It is a large-scale vibrating screen commonly used in large coal preparation plants, coal washing plants, sintering plants, pelletizing plants, and ore dressing plants.

 Judging and debugging the working status of the hydro cyclone 1. The concentration and fineness of the overflow. ⑴ The overflow concentration is small and the fineness is fine. At this time, it is necessary to reduce the pressure or adjust the concentration of the ore, and the small grit nozzle can also be replaced to meet the requirements. ⑵ Large overflow concentration and coarse fineness. At this time, the requirements can be met by increasing the pressure and adjusting the concentration of the ore, or by replacing the large sedimentation nozzle. However, the above adjustment cannot rely on only one method to adjust, because this may make the cyclone work insufficiently normal and stable. 2. The settled sand is discharged in an umbrella shape. The judgement basis is that the angle of the settling is between 10°-20°, and the concentration reaches about 75%, which is the best working condition. If the settling angle is too large, there are three reasons: ⑴ The grit nozzle is too larg

 The high-efficiency graded cyclone adopts a unique feed structure design and is composed of cone segments with different cone angles. While dealing with the same material, compared with the traditional cyclone, the overflow fineness is effectively improved and the classification efficiency is greatly improved. when the same overflow fineness is obtained, the large diameter cyclone can be used instead of the small diameter cyclone. In field use, an overflow of 325 mesh (90%) can be obtained from 63% of coarse-grained materials with-200 mesh after only one classification. The cyclone is separated by centrifugal sedimentation. The two-phase mixture to be separated is fed from the feed port of the hydrocyclone at a certain pressure, thus forming a strong rotational separation movement in the hydrocyclone. Due to the density difference between the light phase and the heavy phase or the particle size difference between the coarse and fine particles, the centrifugal force and the power of t

 As construction sand, washed sand needs to meet certain standards. It is necessary to ensure that the sand washing machine has a good washing effect, the ratio of fine sand to coarse sand is reasonable, and the sand making raw materials should be selected from rocks with higher hardness.  The basic requirements of concrete for sand are as follows: 　　 1. The total surface area of the sand particles should be small, that is, the sand should be as coarse as possible. In concrete, cement paste is effectively bonded through the surface of aggregate particles. The smaller the total surface area of the aggregate, the more economical the cement is. 　　2. The sand has a good particle size distribution. Particle gradation refers to the situation where sands of different particle sizes are matched with each other. The size of the sand particles is reasonably matched to achieve step-by-step filling and reduce the porosity to achieve the highest possible density. It can be seen that the use of wel

  Features Of DMC 1. The separation efficiency of the heavy medium cyclone is relatively higher than that of the ordinary hydrocyclone, which is also one of the important factors that people like to use it. 2. The adjustment range of the separation density of the heavy medium cyclone is relatively wide: the separation density of the heavy medium coal separation is generally 1300 kg/m3 ~ 2200 kg/m3 and it is also convenient to adjust this is its advantage. 3. The heavy-medium cyclone has a relatively strong use capacity and not only has a wide range of sorting strength, but also has a good effect on the quantity and quality of coal preparation. 4. The sorting particle size range is wide. The size limit of the lump coal separator is generally 100-6mm, and the particle size limit of the fine coal heavy medium cyclone is 50-0mm (the sorting depth can reach 0.15mm). 5. The heavy medium cyclone has large processing capacity, the current maximum processing capacity of the heavy medium separat

Screw classifier is used in the dressing plant to match with the ball mill to distribute the ore sand, or in the gravity dressing plant to classify the ore and mud. The particle size classification of the slurry in the metal beneficiation process and the desilting and dewatering of the washing Wait for homework. This machine has the characteristics of simple structure, reliable work and convenient operation. The screw classifier is mainly composed of a transmission device, a spiral body, a trough body, a lifting mechanism, a lower bearing (bearing bush) and a discharge valve. The water tank of the machine is installed obliquely. The inclination angle is determined according to the equipment configuration in the process flow. The transmission device drives the screw to rotate in the groove. After the fine slurry is fed into the groove from the side feeding inlet, a lower end is formed at the groove. The surface area and volume of the slurry settlement area are determined by the inclinat

Tailing is one of the products of the sorting operation in the beneficiation, in which the part with the lowest content of useful target components is called tailings.  Tailings are not completely useless waste, and often contain components that can be used for other purposes and can be comprehensively utilized. Achieving no waste discharge is a requirement for the full utilization of mineral resources and the protection of the ecological environment. Tailing drying screen is designed for the dewatering of tailings. Technical characteristics of tailings dewatering screen: 1. High working frequency, high vibration intensity, low moisture content of the product on the screen, high unit processing capacity, and high solid recovery rate when used for dewatering tailings. 2. Using the principle of self-synchronization, the motor drives the vibrator through a tire coupling, with simple structure and low working noise. 3. Installation with negative inclination angle, the screen surface of the
