Precautions for maintenance of sand making machine equipment

Precautions for maintenance of sand making machine equipment

Common sand making machines on the market today include jaw crushers for coarse and medium crushing, roller sand making machines for medium and fine crushing, hammer sand making machines, rod mill sand making machines, and impact crushers for fine crushing. Sand making machines and hydraulic open box sand making machines, and mobile sand making machines that can meet various crushing needs.

There are various types of sand making machines, just to adapt to different types of materials. The particle size, hardness and humidity of materials are different, which correspond to different sand making machines. If inappropriate materials are put in, it is easy to cause equipment blockage, wear and tear or the output does not meet the requirements.

Bosses who produce machine-made sand often say, “Once the machine sounds, you will get ten thousand taels of gold.” Sand making machines are the core of the production line. If it stops, the gold ten thousand taels will be ruined. Therefore, it is very important to understand the daily maintenance of the sand making machine and ensure the normal operation of the machine.

Let’s take a look at the daily use and maintenance methods of the sand making machine:

Three things to keep in mind when working

1) The crushing chamber should be empty

The starting of the motor is a gradual process. If there is debris in the crushing chamber, the motor will burn out due to excessive pressure when starting. Check before starting to ensure that there is no load, and wait for the motor to run before adding materials.

2) The sequence of switching on and off should be kept in mind

The sequence of starting up is to discharge first, then to the sand making machine, and finally to feed. The sequence of shutdown is just the opposite.

3) The feed should be uniform and stable

Normally, the greater the load, the more wear and tear the sand making machine will have. Try to feed the material at a uniform speed. Do not let the machine run idly or overload suddenly, so as not to crush the impeller and burn the motor.

Five points for attention during maintenance

1) Parts should be checked frequently

Parts are fixed together with other parts by screws. After a long period of machine vibration, the screws will become loose. If left unattended, the loose parts will be unevenly stressed. Therefore, if you hear abnormal sounds during use, stop the machine in time to check whether there is a problem with the parts.

Sand making machines generally work by rock-on-stone or stone-on-iron methods, and there will be a certain degree of wear and tear inside the machine. The parts that wear the fastest are the cutter head or the crushing chamber, hammer head, rotor, etc., which are in direct contact with the material. It is necessary to check the internal conditions through the observation door regularly, and replace it in time when the degree of wear affects the product effect or production efficiency.

Special attention should be paid to the fact that if the impeller is worn and needs to be repaired or replaced, be sure to contact the manufacturer of the equipment, and it is strictly forbidden to replace or manufacture it without permission.

2) The V-belt should be adjusted tight

When maintaining the sand making machine, the V-belt should not be ignored. V-belts will have aging problems during use, and the tension should be adjusted regularly to ensure uniform tension to avoid breakage.

When the sand making machine is driven by two motors, the V-belts on both sides should be grouped and matched to ensure the same length, and the current between the two motors should be equal. If there is a difference, the difference should not exceed 15A, otherwise the current needs to be adjusted. side of the belt.

3) Corrosion should be dealt with in time

Sand making machines, crushers, mills and most mining equipment are all made of steel. It is normal for them to get rusted after long-term open-air operation or erosion by water vapor. Rust is not terrible, but it must be dealt with in time to avoid damage to the machine.

Rust can be removed by chemical agents, open blasting machines, closed blasting chambers, vacuum blasting machines, high-pressure water mills, and impeller blasting.

4) Personnel need to stay away from

The sand making machine runs at a high speed, so you should pay special attention to your own safety when operating it. After starting, personnel should stay away from the work area. During the inspection, the observation door must not be opened when the machine is running. When repairs are needed, the power should be turned off before starting.

5) Lubrication should be timely

For the sand making machine to operate normally, it needs good lubrication. Insufficient lubrication will cause increased wear of the machine, and the bearing will heat up. After a long time, the machine will be damaged. Therefore, we must always pay attention to the addition of lubricating oil. The general saying in the industry is to add lubricating grease after 400 hours of work, clean the bearing after 2000 hours of work, and replace the bearing after 7200 hours of work.

When the temperature of the material is high, thin lubricating oil is used, and the temperature is low. For example, in winter, the lubricating oil will become viscous as the temperature drops, resulting in difficulties in starting and running. Replace the lubricating oil above -25#.
