How to Remove Rust from Sand Sieve Mesh
The core component of a sand screening machine is the sieve drum, typically comprising a hopper, conveyor belt, transmission unit, screening system, and sieve surface cleaning mechanisms; it is mainly used for material handling in concrete mixing stations, sand and stone quarries, etc. Rust on the sieve mesh can be quite a headache, especially after the equipment has been unused for a long time, when a layer of dust and dirt accumulates on the sieve. This can affect the sand screening performance, so it's crucial to clean the dirt from the sieve mesh of the sand screening machine. Here's a look at the cleaning methods.
The entire sand screening equipment consists of a raw material storage hopper, a feeding belt conveyor, a horizontal screen mesh, a finished sand discharge belt, and a waste stone discharge chute. Once powered on, the loader fills the large-capacity storage hopper with raw materials, which are then fed onto the horizontal screen drum by the feeding belt. The rotating drum drives the raw materials to be pushed and tumbled within the drum blades, creating an artificial screening effect as the materials roll over the screen surface. The screened finished sand falls into a collection hopper and is then conveyed onto the finished sand belt, where it is elevated and forms a pile of finished material, or it can be directly discharged into the storage hopper. The entire process is continuous, with clear and accurate material grading. If rust appears on the sand screening mesh, it can be resolved by using warm water, soap, or detergent to clean the mesh. If there is oil污 on the surface of the screen, it should be wiped clean with a soft cloth first before using a cleaning agent. If there is rust on the mesh surface, a specialized cleaning agent is required, and we can also use 10% nitric acid or abrasive detergent to clean the rust stains from the mesh.
Some may wonder why stainless steel sieve meshes can also rust. This is because the surface of the sieve mesh for sand separators has a passivation film, which exists in a stable oxide state and possesses excellent corrosion resistance. However, when the sieve mesh is placed in a specific environment, this oxide film can also be oxidized, leading to rust on the sieve mesh. Once the rusting is severe, continued use of such a sieve mesh can easily result in detachment and damage. Therefore, when the sand separator is not in use for an extended period, it is necessary to properly store both the machine and the sieve mesh for future use.
The core component of a sand separator is the sieve drum. Typically, a sand separator consists of parts such as a storage bin, conveyor belt, transmission unit, screening system, and sieve surface cleaning, mainly used for material handling in concrete mixing stations and sand and stone material yards. How much do you know about this equipment? Users have reported to the sand separator manufacturer that they were unsure how to adjust the equipment upon initial use.
Sand Screening Machine Calibration and Operation Method:Before operation, ensure that there's no accumulated sand in the sand separator.
★ The sand separator has been debugged, and all components have been installed. After passing the inspection, it can be tested for operation. Prior to the trial run, a thorough check should be conducted to ensure that all components are correctly installed according to the drawings, that all fasteners are secure, and that there are no obstructions around the separator that could hinder the operation of the drum separator.
★ Place the rectangular inspection door in the open position and manually rotate the sifter drum using a handwheel. Observe for any jamming or friction in the comb sifter mechanism; if present, adjust using bolts.
★ Ensure that all bearing seats and gearboxes are well-lubricated, and the oil level in the gearboxes is appropriate.
★ Power connectors should be firm, reliable, well-insulated, and properly grounded.
★Additionally, there are some points to consider before and after using a sand screening machine. When operating the sand screening machine, it should be matched with other equipment according to the requirements of processing capacity and material screening. Therefore, users need to clearly understand the requirements for the height of the feed inlet and the machine body height, and then design and produce the equipment accordingly. During operation, do not overfeed material, as this can affect the screening effect and may lead to excessive motor load, damage to the vibrating feeder, impact on the screen, and shorten the lifespan of the sand screening machine.
★When it's time to shut down the sand separator after use, it's important to wait until the sand blocks have been completely separated before stopping to prevent the motor from being overloaded upon startup and potentially burning out. If the operation is outdoors, protective measures must be taken to prevent water from entering the motor's parts, which could destroy the motor upon turning it on. If a motor replacement is needed during use, it's crucial to replace it with a motor of the same model; a larger or smaller model could hinder the normal operation of the separator. It is emphasized that users should regularly inspect the easily damaged parts of the sand separator to avoid any disruptions in use. Users should also check the bearing area during operation and add lubricating oil for maintenance to reduce operating resistance and wear between the bearings. After some time of use, we should also check if the reducer is low on oil to prevent component wear.
