What are the maintenance procedures and requirements for vibrating screen exciters?

In industries such as mining and coal preparation, materials need to be screened and classified before they can be used. Vibrating screens use mechanized vibration to classify materials according to different sizes. They have a large processing capacity and high screening efficiency, which is many times more efficient than traditional manual sorting. They can be said to be a “good helper” for screening work. Однако, if the screen is used improperly, it will cause mechanical failures and short service life. In order to avoid these problems, you need to learn more about the operating steps and precautions of the vibrating screen.

Vibrating screen operation steps

Vibrating screen

1. Inspection before starting

(1) Check whether the starting equipment is in good condition, whether the motor is grounded properly, and adjust the tightness of the V-belt.

(2) Clear the debris on the screen to avoid heavy load starting.

(3) Check and tighten the bolts of each part.

(4) Check and add enough lubricating oil in the vibrator.

(5) Check whether the inlet and outlet chutes are unobstructed, check whether the crossbeams are welded, and check whether the safety protection devices are safe and reliable.

(6) After completing the above preparations, you can send a signal to notify the start-up.

2. Start the machine

Turn the control switch handle to the forward position of the motor, press the start button, close the switch, and start the motor. Observe the operation status. There is no abnormal sound or vibration. It can only run normally after it runs smoothly. It can only be fed after it runs normally. Before starting the equipment, it must be ensured that the discharge port transportation equipment has started and run normally. After confirming that the operation of the vibrating screen is completely normal, send a signal to notify the discharge.

3. Equipment operation

The feeding must be uniform, and it cannot be overloaded or have excessive impact. Pay attention to the temperature and abnormal sound of the motor at any time. Always pay attention to the discharge situation. If there is any blockage, it must be cleared in time. Inspect the nozzle of each vibrating screen for blockage or detachment, and observe the temperature and sound of the motor and the sound of the exciter frequently. Any repair or adjustment of the vibrating screen during operation must be carried out after the power supply of the machine is cut off and the sign prohibiting closing is hung.

How to install the vibrating screen bearing

Installing bearings in a вибрирующий экран is a critical task that requires precision to ensure that the machine operates effectively, minimizes downtime, and maximizes bearing life. Vibrating screens operate under harsh conditions, with heavy loads and high vibration, so proper bearing installation is essential to prevent premature failure.

Vibrating screen bearing installation

vibrating screen

1. Prepare for Installation

Gather Tools and Materials: Make sure you have the necessary tools and equipment, including the correct bearings, tools for mounting (например, bearing pullers, гаечные ключи, молотки), grease or lubricant, cleaning materials, and any special tools for your screen design.

Ensure Proper Conditions: Perform the installation in a clean, dry environment to avoid contamination of the bearings. При необходимости, use a workbench with sufficient space to handle the components.

2. Осмотрите подшипники

Проверьте наличие повреждений: Перед установкой, inspect the bearings for any signs of damage (such as cracks or dents) или загрязнение. Ensure the bearings are the correct size and type for your vibrating screen.

Clean Bearings: If the bearings are new, ensure they are free of dirt or debris. Wipe the bearings with a clean cloth if needed. If you’re reusing old bearings, thoroughly clean them before installation.

Как улучшить коэффициент использования материала брикетировочной машины?

In today’s increasingly tight resources, improving the material utilization rate of industrial equipment has become an important means for enterprises to reduce costs and enhance competitiveness. As a kind of equipment widely used in metallurgy, строительные материалы, химическая промышленность и другие отрасли, the material utilization rate of the briquetting machine is directly related to the production efficiency and economic benefits of the enterprise. This article will explore how to effectively improve the material utilization rate of the ball press through a series of measures, in order to provide a reference for related industries.

Material utilization rate of the briquetting machine

briquetting machine

1. Accurately control the moisture content of the material

The moisture content of the material is a key factor affecting the molding effect of the briquetting machine. If the moisture content is too low, the adhesion between the materials is insufficient, resulting in the fragile pellets after molding; if the moisture content is too high, the pellets will be too soft and lack strength. Поэтому, it is very important to accurately control the moisture content of the material. This can be achieved by adjusting the amount of water added during the mixing process or pre-drying the material before pressing.

2. Reduce impurities in the material

Impurities not only affect the quality of the pellets, but may also damage the ball press. By removing impurities in the material by pre-screening or using methods such as magnetic separation, the purity of the material can be improved, thereby improving the material utilization rate of the ball press.

3. Reasonable use of additives

The use of additives can improve the molding performance of materials, but they need to be reasonably selected according to the characteristics of the materials and production requirements. The right amount of additives can improve the strength and molding rate of the pellets, but excessive use will increase costs and even affect the quality of the pellets.

4. Optimize the particle size of the material

The particle size of the material has a direct impact on the molding effect of the briquetting machine. Слишком крупные или слишком мелкие частицы повлияют на формовочный эффект материала.. Обычно, Размер частиц материала должен контролироваться между 80 и 200 сетки для обеспечения равномерных зазоров между частицами материала и улучшения качества формования.

5. Улучшить чистоту материала

Чем выше чистота материала, тем лучше эффект формования. Материалы высокой чистоты могут уменьшить влияние примесей на эффект формования., повысить прочность и долговечность пеллет, и, таким образом, улучшить коэффициент использования материала шарового пресса.
