Ten common faults of ore sand making machine are easily solved

Ore sand making machine, also called vertical impact crusher, is the preferred equipment for sand making equipment. Our company has rich experience in the production of ore sand making machine equipment, and can also directly reach the problem when dealing with various problems. We will produce it today. The problems encountered in the process are summarized here again, so that these events can be solved or avoided in the future production process.

The equipment makes abnormal noise during the working process

Cause of failure: The connecting bolts inside the sand making machine, lining plates, impellers and other wearing parts are loose and fall off.

Solution: Stop immediately, retighten and install loose or dropped parts.

The equipment does not run smoothly, and the fuselage swings too much

Causes of failure: 1. The wearing parts on the impeller are seriously worn; 2. The feeding particle size is too large; 3. The impeller runner is blocked, causing uneven feeding and swinging.

Solution: 1. Replace the wearing parts and balance the internal impeller of the sand making machine; 2. Strictly control the feeding particle size, which cannot exceed the maximum allowable value of the equipment; 3. Take out the blockage on the impeller runner and clean the crushing cavity frequently.

Bearing temperature rises

Causes of failure: 1. Dust and foreign matter enter the bearing components; 2. The bearing is worn and broken; 3. The bearing is short of oil.

Solution: 1. Clean up foreign bodies; 2. Replace new bearings; 3. Add lubricating oil on time.

The upper and lower sealing rings of the shaft are damaged

Cause of failure: The upper (lower) bushing is heated due to the friction between the upper (lower) bushing and the bottom of the upper (lower) gland, which will be damaged over time.

Solution: Replace the upper and lower sealing rings with new sealing rings.

The bearing operation is not flexible

Cause of failure: foreign objects such as materials enter the bearing sealing cover of the sand making machine.

Solution: Open the sealing cover and clean up foreign objects.

The sound of the machine suddenly becomes louder and there is a rumbling sound

Causes of failure: 1. Bearing or gear problem; 2. Loose bolts; 3. Serious wear of parts.

Solution: 1. Check whether the bearings and gears are in good condition, and repair or replace them in time; 2. Fasten the bolts; 3. Replace the worn parts.

The idling resistance is too large

Cause of failure: The bearing seal cover is blocked by material.

Solution: Remove the blocked material from the bearing and check whether the corresponding device is blocked by the material.

Working principle of vertical impact crusher

There is a metal collision sound in the sand making machine

Cause of failure: loose bushing, impeller or other parts worn.

Solution: Check, tighten or replace all relevant parts of the machine.

Oil seepage on the upper and lower ends of the shaft

Cause of failure: As the sealing ring moves up and down with the bearing, the sealing ring is worn and oil leakage occurs.

Solution: replace the sealing ring.

The discharge particle size becomes larger

Causes of failure: 1. Due to the long-term operation of the equipment, the V-belt of the transmission part is loose; 2. The feed particle size is too large; 3. The impeller speed is unreasonable and the efficiency becomes low.

Solution: 1. Adjust the tightness of the belt; 2. Strictly follow the feeding requirements of the sand making machine (if the feeding is too large, the equipment swings too much; if the feeding is too small, it is difficult to achieve the 3. Adjust the speed of the impeller until it reaches the ideal standard.

The ore sand making machine plays an irreplaceable role in the sand making of various ores, and is the most effective, practical and reliable sand making equipment at present. The above 10 types of failures are frequently encountered problems in the production of sand making machines. In addition, if there are other unexplained failures during operation, it cannot be taken lightly, and the machine should be stopped immediately to avoid damage to other components.
