The vibrating screen is widely used in coal preparation, mineral processing, building materials, power and chemical industries. This screen machine has the characteristics of * structure *, strong excitation force, low vibration noise, easy maintenance, and durability. Next, let's talk about several key details to pay attention to when using a vibrating screen, as well as several common faults caused by low temperatures in winter.
Details of using a vibrating screen:
1. The operator and sand making machine manufacturer suggest that everyone should have a detailed understanding of the basic structure and working principle of the vibrating screen, and regularly check, summarize experience, and record operating data.
2. Before removing the transport fixing plate, the sand making machine throwing head manufacturer recommends not to turn on the vibration motor. If the fixed plate is not removed before starting, it may cause damage to the equipment, vibration motor, and may result in personal injury.
3. Before each start-up, check whether the screen is tightly pressed, leveled, and whether the tie ring screws are locked.
4. Before each start-up, necessary inspections should be carried out, focusing on checking whether the lubrication is good, whether the connecting parts are loose, and whether there is any jamming between the moving parts. Attention should also be paid to ensuring the necessary clearance between all moving parts and fixed parts. And after working for 8 hours, tighten all the fasteners of the equipment again.
5. Each time the vibrating screen is started, it should be ensured to operate in an unloaded state. After the screen runs smoothly, the machine should be stopped only after the material inside the screen box has been drained.
6. If the vibrating screen experiences abnormal conditions during operation and requires maintenance or routine upkeep, it must be shut down for implementation. Dynamic maintenance or upkeep is strictly prohibited.
7. The manufacturer of the sand making machine throwing head believes that necessary routine maintenance and regular repairs are required after the equipment is put into normal use, especially lubrication of the vibration motor bearings.
Possible faults of vibration screening machine caused by low temperature in winter
1. Cannot run
When the screening machine cannot operate normally, the motor and bearings may not run smoothly due to low temperature. This problem usually occurs when the vibrating screen is installed outdoors without proper protective measures. To solve this problem, we can install protective covers and take anti freezing measures at the motor and bearing parts. Antifreeze can be added to the motor and bearing parts to prevent the lubricating oil from thawing;
2. Low screening efficiency
This problem mostly occurs in screening materials with liquids. In winter, the temperature is low, and when screening materials containing taxes, ice will form and adhere to the sieve, thereby reducing screening efficiency. The solution to this problem can increase the liquid temperature of the material within the allowable range (generally maintained at 10 ℃), and clean the sieve mesh in a timely manner after the screening work is completed to ensure that there is no liquid residue on the surface of the sieve mesh;
3. Frequent malfunctions
If the quality problem of the screening machine itself is excluded, the solution to frequent malfunctions is to strictly follow the user manual for operation. Regularly inspect and maintain the screening machine, and make handover records during shift changes. The maintenance of vibrating screens in severe cold environments is very important, only high-quality vibrating screens can withstand the test of harsh winter.
