JR系列直線振動篩 produced by Xinxiang Jiarui Electromechanical Manufacturing Co., Ltd. uses a vibrating motor as the excitation source, causing the material on the screen to be thrown up and move forward in a straight line. After the material is evenly fed into the feed port, it can be sieved through single- or multi-layer screens (1–6 layers) to separate materials by particle size. The oversize and undersize materials are discharged separately from their respective outlets. It has a large production capacity per unit, a simple structure, and is easy to maintain.
A dustproof cover can be added based on the material properties, and the fully enclosed structure prevents dust from escaping, creating a dust-free workshop. It can be connected with other equipment to form a production line. It is suitable for multiple industries such as food, pharmaceuticals, chemicals, building materials, and metallurgy, and we also provide non-standard customization services.
Proper linear vibrating screen operation is essential to maintain stable screening efficiency and extend equipment service life.
Let’s take a look at the operation and maintenance of the linear vibrating screen.

Linear Vibrating Screen Operation
Step1:Linear Vibrating Screen Preparation Before Operation
Before performing screening operations, a systematic inspection of the vibrating screen is required. This is a critical step to ensure the equipment operates smoothly and safely during screening.
通電前的基本安裝檢查
- 拆除防護裝置： 若機器為首次使用，必須拆除運輸期間用於固定機器的支撐裝置或防護框架。否則，篩機可能受損並縮短使用壽命。.
- 檢查機器位置與篩網: Check if the machine is placed horizontally and stable without shaking; ensure that both foot bolts on either side are tightened securely to prevent the machine from moving randomly, which could affect its operation and safety. Inspect the screen mesh for any damage or protrusions, as these would impact the screening accuracy and prevent guaranteed precision in screening.
- 檢查清網裝置： Before starting the machine, residual materials on the screen surface and discharge port should be cleaned promptly to prevent accuracy from decreasing and inaccurate material screening caused by clogging. Check the de-clogging devices such as the spring balls in a timely manner to ensure they are intact and not missing, guaranteeing the normal operation of the de-clogging devices. This reduces the phenomenon of repeated shutdowns due to clogging and improves screening efficiency.
- 確認電機旋轉方向： Check if the vibration motor angles are synchronized and consistent, and ensure that parts such as the power interface are in good contact with no damage to prevent machine damage.
- 檢查進出料口的密封性： If there is a need to integrate the production line, it is essential to carefully inspect whether the discharge port has already been properly sealed in contact with upstream and downstream equipment to prevent leakage or mixing of materials, thereby ensuring the quality of the materials.
Step2: Startup and Operating Procedures
啟動運行前
在進料之前，應先讓機器空載運行，以檢查其各方面運行是否正常，避免因此延誤運行進度。.
- Start without loading material first. Start the equipment first without pouring any material into it, run it for about 3 minutes, check if the vibration motor inside the machine vibrates synchronously and if the operating direction is correct, ensuring there are no abnormal noises or significant shaking of the machine.
- When the machine starts up, it operates normally. The material is then fed into it. The material needs to be evenly fed back and forth across the screen surface according to its width to avoid uneven force distribution on the screen when feeding from one side only. This prevents the material from deviating on the screen surface, which would otherwise affect screening efficiency and accuracy.
運行期間
空載測試運行後，確認各方面無異常，即可進行投料試運行，進入正常篩分階段。.

This prevents the material from deviating on the screen surface, which would otherwise affect screening efficiency and accuracy.
- 投料時應均勻連續供料，且不應從高處拋入篩網，以防止強烈衝擊力造成篩網損壞。.
- 篩分機運行期間，需持續監控其運行狀態的各個方面，例如是否有異常噪音、振動或馬達溫度過高等情況。.
Step3: Shutdown Procedure After Operation
Power must be turned off and the machine shut down only after all material on the screen has been emptied. If connected to a production line, upstream feeding equipment should be stopped first to extend the screen’s lifespan.
Linear Vibrating Screen Maintenance Tips
正確維護機器是延長其使用壽命的關鍵步驟。.
- Daily maintenance: After the machine stops, the sieve mesh and sieve box need to be cleaned promptly to prevent residual material buildup, which could affect the accuracy and efficiency of subsequent material sieving.
- Check if the screen mesh is damaged or bulging, and ensure the cleaning device is intact to guarantee the machine’s screening efficiency.
- Check if the motor is overheating and if there is any material leakage; the spring and other accessories remain intact with no signs of breakage.
- Regularly clean the machine, check for aging of wiring and various components, tighten screws and bolts, and prevent equipment failures and shutdowns.
