Sand making machine is a kind of equipment used to crush large stones or ores into sand, which is widely used in the production process of construction, mining, water conservancy, transportation, and other industries. It is mainly used for manufacturing artificial sand (mechanism sand) and for processing many kinds of stones such as river pebbles, limestone, granite, basalt, and so on.
Sand Making Machine Types
Sand making machines is divided into various types according to the working principle and structure, including:
- Impact sand making machine: stone material is thrown to the impact plate for crushing by the high-speed rotor, which is suitable for fine crushing of hard materials.
- Vertical Shaft Impact Sand Making Machine (VSI Sand Making Machine): Commonly used in ore shaping and sand making, the output sand grains have better shape and even particle size.
- Impact Sand Making Machine: Utilizing the impact between the impact plate and stone material for crushing, suitable for sand making of medium hardness material.
- Hammer sand-making machine: It relies on a high-speed rotating hammer to strike the material, which is suitable for crushing medium hardness and brittle materials.
- Roller sand-making machine: This machine adopts two rollers to crush and grind the materials, which is suitable for fine crushing of soft stone materials.
The sand-making machine is usually used in conjunction with a crusher, screening machine, sand washing machine, and other equipment in the mechanism sand production line.
Sand Making Machine Failure
Sand making machines in the process of long-term use, there may be a variety of failures, which is usually due to a variety of reasons such as wear and tear of the equipment, improper operation, inadequate maintenance, or environmental factors. Common sand-making machine failures and their causes include:
| Item | Failure Causes | Solution |
| 1. Abnormal sound during the use of sand making machine | The connecting bolts, impellers or liner plates and other vulnerable parts in the sand making machine are loose and fall off. | Immediately stop the machine operation, and re-tighten the loose or falling parts. |
| 2. Sand-making machine running instability, the body swing too big | (1) Dust and foreign matter entering bearing parts; (2) Bearing wear; (3) Lack of oil in bearings. | (1) Replace the bearing with a new one; (2) Clean up the foreign matter; (3) Increase the lubricant on time. |
| 3.Bearing temperature rises | (1) Dust and foreign matter entering bearing parts; (2) Bearing wear; (3) Lack of oil in bearings. | (1 )Replace the bearing with a new one; (2) Clean up the foreign matter; (3) Increase the lubricant on time. |
| 4. Bearing running inflexible | sand making machine bearing sealing cover inside the material and other foreign matter caused. | Open the sealing cover of the sand making machine and clean the machine. |
| 5.Bearing upper and lower seals are damaged. | The upper (lower) shaft sleeve is hot due to the friction of the upper (lower) cover bottom surface, and the upper (lower) shaft sleeve is damaged for a long time. | Remove the damaged upper and lower seals and replace them with new ones. |
| 6.Sand making machine inside the metal collision sound | Impeller, liner loose or other parts wear. | Check, fix or replace the relevant parts of the machine. |
| 7.Granularity of discharged material becomes large | (1) The triangle belt of the transmission part is loose because of the long running time of the equipment; (2) The feed particles are too large; (3) The rotational speed of the impeller of the sand making machine is too low and unreasonable, resulting in low efficiency and large particle size. | (1) Adjust the belt tightness; (2) Strictly in accordance with the sand making machine feeding requirements feeding too large, feeding too small, collision crushing is not enough to meet the requirements of the finished sand); (3) Adjust the rotational speed of the impeller until it reaches the ideal standard. |
| 8.The machine suddenly becomes louder with a rumbling sound | (1) The sound becomes louder caused by loose bolts; (2) The bearings or gears of the sand making machine have problems causing the sound to become louder; (3) The wear parts of the sand making machine are seriously worn out causing the sound to become louder. | (1) Tighten the loose bolts; (2) Check whether the bearings and gears of the sand making machine are intact, and repair or replace the bearings and gears in time; (3) Replace the worn-out wearing parts in time. |
| 9.Oil seepage from the upper and lower ends of the shaft | The seal ring should move up and down with the bearing, resulting in seal ring wear and thus causing oil leakage. | Remove the worn sealing ring and replace it with a new one. |
| 10.Idle resistance is too large | The sealing cap on the bearing is blocked by the material. | Remove the blocked material from the bearing and check whether the corresponding equipment is blocked. |
How to Extend The Service Life of Sand Making Machine?
To extend the service life of the sand-making machine, ensure its long-term stable operation, and improve production efficiency, you can take the following measures:
Regular maintenance and upkeep
- Regular inspection: each key component of the sand-making machine (such as impeller, bearing, rotor, liner plate, etc.) should be inspected regularly to ensure that there is no excessive wear or looseness. Repair or replace the parts in time when problems are found to prevent small problems from developing into big failures.
- Lubrication and maintenance: Ensure that the bearings, transmission parts, and other friction parts of the sand-making machine are adequately and appropriately lubricated. Use high-quality lubricating oil or grease and replace it regularly to prevent premature wear of the equipment due to insufficient lubrication or oil pollution.
Standardized operation
- Avoid overloading: the load of the sand-making machine should be controlled within a reasonable range, and should not be overloaded for a long time. Overloading will cause the machine parts to wear out too quickly and shorten the life of the equipment.
- Control the production capacity: adjust the production capacity according to the specification parameters of the sand-making machine and the working environment, don’t pursue the production speed excessively, and avoid bringing too much pressure to the equipment.
- Standardize the operation process: the operation of the equipment should be carried out by trained professionals and standardized in accordance with the operation manual provided by the manufacturer to avoid damage to the equipment or a decrease in production efficiency due to improper operation.
Daily maintenance
- Clean up material accumulation and clogging: Clean up the material accumulation inside the equipment regularly to prevent the equipment from running poorly due to material clogging, resulting in increased vibration, noise, and wear.
- Anti-corrosion and anti-rust measures: sand making machines are prone to corrosion and rust when exposed to moisture, dust, and other environments for a long time, so they need to take anti-corrosion and anti-rust measures, especially when working outdoors, pay attention to the protection of the equipment.
Through these effective measures, not only can you extend the service life of the sand-making machine, but also improve production efficiency, reduce downtime, and save maintenance costs.
