1. Vibration motor steering / insufficient excitation force of vibration motor:
When using a linear screen, two horizontal vibration motors are used as vibrating screens. The rotation of the motors is divided into forward and reverse rotation. Under normal circumstances, the rotation of the two motors is in opposite directions, but if the user connects the power to the positive and negative The wrong pole connection will cause the motor to rotate in the same direction, and the problem of the screen surface material will not run out;
2. The problem of motor installation position:
There are three installation positions of the linear screen vibrating motor: bottom, two sides, and top. If the vibrating motor is installed close to the feed inlet, the screen surface will run for a certain distance, and the speed will decrease and stay on the screen surface;
3. The height of the discharge port higher than the screen surface:
When designing a linear screen, if the discharge port is higher than the screen surface, the problem of material stagnation on the screen surface will occur during the production process.
4. The screen surface of the screen is not tensioned or damaged
The tension of the screen and the flatness of the screen surface directly determine whether the force of the material is uniform and the speed of feeding and feeding. In the process of long-term use, due to the impact of the material or the wrong feeding method, the screen surface will be loose or damaged. This is usually the culprit that causes the linear vibration screening machine to not move; replace the screen If the net is not tensioned and then fixed, it will also cause the problem of slow feeding.
5. The screen box is not installed horizontally
The screen box of the small linear vibrating screen is the placement frame of the screen and the grid. Its level directly affects whether the screen and the grid are level. If the screen box cannot be installed horizontally and horizontally, it will cause The inclination of the screen surface causes deviations in the force of the material, which makes it impossible to flow in a straight line according to the schedule.

1. The non-feeding of the linear vibrating screen often occurs in the design, production and power connection problems. When the user connects to the vibrating motor, there will be a wiring prompt on the motor. When connecting, the user should carefully read the instruction manual of the linear vibrating screen and the motor manual. After the power is successfully connected, run it and observe the motor rotation. If the rotation direction is the same, please stop and adjust immediately Motor connection line. After the motor line is connected normally, if the material is still stagnant, you should check the motor installation position and the height of the discharge port. The height of the discharge port can be observed intuitively, but the installation position of the motor needs to be determined technically, so if you find the above problems, please contact the manufacturer immediately.
2. Regularly check the tension and flatness of the screen. When replacing the screen, it must be replaced in strict accordance with the requirements of the linear screen manufacturer. There must be more than two people to cooperate, one person is responsible for tensioning the screen, and the other is responsible for tightening Sieve. It is worth noting that when feeding, we must adopt a uniform and quantitative scientific feeding method, which can effectively avoid the slack and damage of the screen surface caused by the uneven thickness of the material on the screen surface.

Grain transportation is an important part of the whole grain industry, a lot of grain may be in the process of transportation because of improper operation of the grain caused by secondary pollution or damage, which will cause waste of grain, for the manufacturer is also a loss of money, so many people in order to avoid such things happen will use professional grain transportation equipment suction machine, the following we will talk about What are the advantages of this equipment.
1, grain suction machine in the process of work to a greater extent to ensure that the grain of the sterile environment, but also to dry food processing, we all know that if the grain in the process of transportation moisture is directly lead to food spoilage.
2, grain suction machine can be very fast to complete the transport work, more efficient than the traditional manual transport, and can also be operated so that the grain to reach the designated location, the operation is also very convenient.
In short, the grain suction machine has numerous advantages, which is why it is used by many manufacturers, then, if there is a demand, be sure to find a professional and regular manufacturers to buy.

Grain suction machine is a professional agricultural equipment, mainly used to suck flour or other fine grain materials. In the process of operating the grain suction machine, there are many matters that need attention, according to the requirements of the operation can make the grain suction machine to play a maximum role, the following points may wish to learn.
1, before using the grain suction machine to check whether the air source is clean, if not clean, the cylinder and solenoid valve will appear blocked, which in turn affects the performance of the whole system, so make sure that the air source is clean. There is also to ensure that the pressure is in the normal range, if the air pipe at all levels is not firmly connected together, it may appear that the air pipe falls off, which will bring safety hazards.
2, before each use to check whether the various parts of the grain suction machine is firmly connected to avoid any safety problems. If there is a safety problem, press the emergency stop button, so that the damage in all aspects can be minimized.
3, grain suction machine work process if the feeding pipeline failure, to close the feeding valve, wait until the check is clear and troubleshooting before you can continue to use.
So, want to let the grain suction machine can play the biggest role, then, in the use of the above aspects must come and, can not be ignored.

1. If this problem occurs when the newly purchased product is used for the first time, you should check whether the screen mesh of the rotary vibrating screen is at the same level as the outlet. If the screen mesh and the outlet are not level, it will cause the rotary vibrating screen to discharge The problem of slowness arises.

2. The second case is the adjustment of the motor angle. The angle of the eccentric block of the vibration motor of the rotary vibrating screen can be adjusted to change the trajectory of the material moving on the screen surface. The smaller the angle, the faster the material will spread out ;The larger the angle, the slower the material will spread out. Generally, the motor angle is adjusted to 35 degrees to 45 degrees. If the angle is above 45 degrees, there will be a problem of slow discharge, which is suitable for screening materials with less impurities.

The solution to the slow discharge of vibrating sieve

1. Increase the weight of the two heavy hammers

2. Change the included angle of the upper and lower weights

Ultrasonic vibrating screen is a screening equipment for fine materials, which can be widely used in the screening of food, medicine, chemical industry, metal powder and other materials. However, some users reported that the ultrasonic transducer overheated during use. So what factors are causing this problem? How to solve it?

1. There is material residue at the transducer interface

The transducer is installed on the screen frame. Due to long-term operation, the interface between the transducer and the screen frame will become loose, and excessive material falling to the interface of the transducer will cause poor heat dissipation of the transducer, thereby cause the transducer to heat up.
For this problem, we can check the transducer regularly, stop it immediately for maintenance if it is loose, and clean it up immediately if there is residue.

2. The short circuit of the connecting line causes the transmission signal to be abnormal

The ultrasonic screening system is composed of a transducer and an ultrasonic power supply, and the cable is connected to the two. If the cable is damaged, the transmission power will be abnormal and the temperature of the transducer will be abnormal. For this problem, we can check the connecting wire before and after production, and replace it immediately if any damage is found;
3. Ultrasonic power problem

For the parts that provide ultrasonic waves to the transducer, the output power will be unstable when the ultrasonic power supply fails. In the long run, the temperature of the transducer will be abnormal, which will affect the screening accuracy and output. When starting the ultrasonic power supply, please check the equipment in advance to ensure normal operation;

4. Voltage instability

Both the vibrating screen and the ultrasonic system require electricity to maintain operation, so if the power supply is unstable, it will also cause the transducer to overheat. Therefore, please check the connection cables regularly during production to ensure that the cables are normal and the power supply is stable.
