The rod mill sand making machine is widely used in the sand and gravel industry, and it is one of the more traditional river pebble sand making machines for construction sand and river pebble sand making machine, which is mainly used for the processing and crushing of raw materials such as feldspar, quartz, and ore. The cylinder rotates at a certain speed, and the grinding body rises to a certain height under the action of friction and centrifugal force and is thrown down, so that the material is subjected to impact grinding and grinding to achieve the purpose of sand making

The above several kinds of river pebble sand making machine, river pebble sand making machine have their own advantages and disadvantages, is the rod mill sand making machine discharge is mostly construction fine sand, and the impact crusher discharge grading is the best, users need to choose equipment according to their respective conditions

If the installation is not correct, it will directly affect the production of the sand making machine, if the installation is not correct, it is likely to lead to the failure of the sand making machine, which will affect the service life of the equipment, and also affect the efficiency of the sand making production line, so how to install the sand making machine correctly? Below Wally, we will introduce you to 5 methods:

Check the sand making machine to see whether the sand making machine is damaged during transportation, then count the various parts of the sand making machine, according to the packing list, to see if there is any omission or deformation, etc., and finally check whether the scale and relative orientation of the anchor bolt hole are consistent with the equipment on site. After the inspection, prepare for the installation work.

The sand making machine will bear the effect of force in the work, so it is generally installed on the concrete, and the concrete structure should be able to withstand 4 times the weight of the sand making machine, so as to ensure that it can bear the load of the sand making machine, and can be installed in the plant or outdoor operation according to the needs of the sand making airport, in order to reduce the vibration phenomenon produced in the production process of the sand making machine, shockproof materials should be added on the basis of the sand making machine and concrete.

Keep the spindle straight during installation, calculate some foundation height, area, depth and soil conditions of the sand making production line at the same time, pay attention to remove the protective film and dust and oil stains on the packaging during installation, pre-detect and pre-install the parts and key fittings of the equipment, avoid rework in the installation process, and affect the installation progress and quality, in order to facilitate future maintenance work, a part of the space can be reserved during installation.

After installation, check the lubrication of the equipment, add lubricating oil in time when the lubrication is insufficient, check whether there are foreign objects in the sand making machine, whether the bolts are installed firmly, whether the motor belt is tightened and whether the wiring is good, keep its rotation direction consistent with the sign, do not reverse rotation, and start the equipment after all inspections.

After checking the installation of the sand making machine, the sand making machine can be started for idling test, observe whether the sand making machine has abnormal vibration and sound during the test run, observe the operation of each component, and feed the equipment evenly and continuously after there is no abnormality, and then start the load. In addition, it should be noted that the equipment can not be overhauled during the operation of the equipment, and can only be carried out after the shutdown, and the operation of the sand making machine should be carried out in strict accordance with the instructions of the sand making machine.

The above is the installation method of the sand making machine introduced to you, the correct installation of the sand making machine is very important, which is related to the safety of the entire sand making production line, and also affects the production efficiency of the sand making production line, therefore, the correct installation of the sand making machine is very important.

Replace wearing parts regularly.

The sand making machine generally works in the open air, exposed to wind and rain, and the working environment is very harsh. In addition, when working for a long time, the working intensity of each part of the equipment is relatively high, and problems such as wear and tear are relatively easy to occur. If basic maintenance is not done well, the cost of production will be high.

Therefore, regular maintenance must be carried out during the use of the sand making machine.

If there is any material in the crushing chamber, the motor will burn out due to excessive starting pressure. Therefore, before starting, it is necessary to pay attention to cleaning the debris in the crushing room to ensure that the no-load start, and then add the machine-made sand raw materials.

Different specifications of sand making machines have different requirements for the feed size, hardness, humidity and so on of the material. When the hardness, agglomeration and humidity of the material exceed the bearing range of the equipment, blockage, wear and tear will occur, and the damage to the sand making machine is very serious. Therefore, the selection of manufactured sand raw materials must match the specifications of the sand making machine equipment.

Regular shutdown, open the observation door to observe the internal wear, serious wear should be repaired or replaced with new parts in time to avoid affecting the normal operation of the sand making machine, special attention should be paid to the fact that without the approval of the manufacturer, it is strictly forbidden to manufacture impellers.

The sand making machine can only run normally and efficiently if it is well lubricated. When lubrication is insufficient, the wear and tear of the machine increases, and the bearings become hot, which can damage the machine. Therefore, the sand making machine checks whether it is necessary to add lubricating oil after using it for a period of time.

The grease of the sand making machine should be added appropriately after 400 hours of work, the bearings should be cleaned after 2000 hours of work, and it needs to be replaced after 7200 hours of work.

The parts of the sand making machine should be tightened in time when they are loose, the parts are fixed together by screws and other parts, if they move frequently and violently, these screws will become loose, and if there is abnormal noise during use, they should be stopped for inspection in time. Find the loose parts and tighten them in time.

The sand making machine needs to rest after working for a long time, and in order to pursue a high level of production output, if it is operated day and night, the equipment will definitely accelerate its damage. Therefore, according to the strength of the crushed material, it is very necessary to stop the equipment and adjust the rest after working for a period of time in the basic maintenance of the sand making machine.

The above introduces the basic maintenance and maintenance work of 5 sand making machines, I believe that we have a certain understanding of the maintenance work of sand making machines, and it is inevitable that there will be many failures when the sand making machine works for a long time, and the maintenance and maintenance work is very important at this time, and it must be paid attention to.

The sand making machine is widely used in the production of building materials, building aggregates, cement and concrete industries due to the advantages of uniform sand grain shape, simplified production process and long hammer life, but when the sand making machine equipment is used, there may be low efficiency and other phenomena, what is the reason for this?

For the production of sand making machine, if the quality of the sand making machine equipment is not good, it will receive friction force during production, which will be subject to greater wear and tear, so that the sand making machine will fail, which will not only reduce the production efficiency of the sand making machine equipment, but also reduce the service life of the sand making machine equipment and increase the maintenance cost, so when purchasing the sand making machine equipment, it is necessary to judge the quality of the sand making machine equipment, so as to ensure a good output;

If the model of sand making equipment is unreasonable, the sand making machine will not be able to successfully complete the processing of materials, and it may also aggravate the wear and tear of the sand making machine, resulting in frequent failures of the sand making machine. For example, if the selected sand making machine model does not match the humidity of the machine-made sand material, it may lead to the blockage of the sand making machine, which will affect the production efficiency of the sand making machine, so the selection of the sand making machine model is an important reason to ensure the smooth production of the sand making machine equipment;

If the quality of the sand making machine is good and the model is reasonable, but the operation mode of the sand making machine is unreasonable, it may also reduce the production efficiency of the sand making machine. For example, the feeding speed of the sand making machine is greater than the processing capacity of the sand making machine, and the material will not have time to be processed, which will lead to the phenomenon of material blockage and stuffiness of the sand making machine, and the production efficiency of the sand making machine will be delayed.

The above mainly introduces the three reasons for the reduction of the production efficiency of the sand making machine, namely the quality of the sand making machine equipment, the selection of the model and the operation method, for these three aspects are analyzed, the purchase of the sand making machine should not only pay attention to the quality, but also choose the appropriate sand making machine model, the operation of the sand making machine should be standardized and reasonable, so as to ensure the production efficiency and service life of the sand making machine.
