  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.

Recently, the emergency disposal project of the silt landfill site has successfully passed the handover and acceptance. 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...
