What Is a Sand Conveyor?
The sand mixer is a device for uniformly mixing the various components in the molding sand and effectively covering the surface of the sand with a bonding agent. Sand mixer is the main equipment for foundry sand processing and molding sand mixing, and it is also the key equipment to obtain qualified molding sand [1] .
- The sand mixer will be used for foundry sand, binder,
- Anti-wear protection plates are added to the bottom plate and outer ring of the sand mixer to improve the effect of rolling and grinding materials and the service life of the whole machine.
- The height of the roller on the roller can be adjusted automatically. When encountering difficult to crush materials and thick material layers, the roller automatically rises to ensure safety.
- Uses: Core sands are mixed in the foundry, which can be used to mix particles or powdery materials in glass, ceramics, chemical, building materials, molding and other industries.
- As China develops from a foundry country to a strong country, the casting technology will continue to improve and improve. In order to adapt to the emergence of new casting technologies, new processes and various new products, the foundry sand mixing equipment will also develop. Various large-scale foundry sand mixing opportunities have emerged.
- During the development of small and medium-sized foundry production,
- 1. Only those who pass the examination and hold the equipment operation certificate are allowed to perform the operation. The operator must strictly abide by the relevant safety, transfer and other systems.
- 2. Before work, oil should be filled strictly in accordance with the lubrication regulations, and the oil quantity should be kept properly. The oil path is clear, the oil mark (window) is conspicuous, and the oil cup and linoleum are clean.
- 3. Check whether the various parts of the machine are intact, whether the rollers are rotating flexibly, and whether the size of the scraper is properly adjusted, and then run dry for 3-5 minutes. Make sure that the parts are normal before adding sand and material. load.
- 4. When the sand mixer is rotating, it is not allowed to pick up the material by hand and clean the roller. It is not allowed to reach into the roller to add various materials. Sampling must be taken from the sampling hole.
- 5. Both new and old sand must be sieved to prevent the sundries such as iron nuggets from being thrown into the roller to damage the machine.
- 6. Stop the car for some reason. The sand and materials in the roller should be cleared before starting. Do not force the car to start.
- 7. During operation, the operator must not leave, and should always pay attention to the sound and rollers, and should stop immediately when abnormal conditions are found.
- 8. When the roller is not completely stopped, it is not allowed to put your hands and other equipment into the roller, and when entering the roller for cleaning and maintenance, in addition to turning on the power switch, the warning of "Someone is overhauled and not allowed to close" is displayed. Outside the card, there is also a person to guard.
- 9. After work, you must check and clean the equipment, do the daily maintenance work, put all operating handles (switches) in neutral (zero position), and turn on the power switch to achieve neatness, cleanness and safety.
- 1. Before entering the workshop, you must wear protective equipment such as protective shoes, hard hats, masks, gloves, etc. Otherwise, you are not allowed to enter the workshop.
- 2. The operator of the sand mixer must be familiar with the structure and performance of the equipment used.
- 3. The new sand of the sand mixer needs to be screened and dried; the old sand can only be used after the sand is recycled.
- 4. When adding resin and curing agent, gloves and glasses must be worn and handled carefully to avoid splashing on the body. Requires accurate ratio.
- 5. Before starting the sand mixer, check whether there are obstacles on both sides of the guide rail. During driving, pay attention to pedestrians passing by.
- 6, when working, there should be a special person responsible, not to other people to operate, to avoid illegal operations.
- 7. When the sand mixer is overhauled, in addition to cutting off the power, a special person is required to monitor it.
- 8. When cleaning the sand mixing tank, shut down and clean up, clean the spiral blades, and prepare for the next sand mixing.
- 9. Clear the sand and objects scattered on the work site in time, keep the work site and pedestrian passages clean and tidy for safety.
