    The cobblestone sand making machine is specially used to produce the mechanism sand, that is, the sandstone raw material is crushed to a certain fineness to be qualified, such as the 3mm fine sand commonly used in the market. This new type of sand making machine has undergone many times of practice verification and technical improvement, so it can adjust the fineness of discharge according to the customer's wishes, in line with the development trend of the modern construction industry. With the continuous growth of science and technology, our cobblestone sand making machine has already realized automatic operation, which greatly reduced the labor input during the production of machine sand and the problems caused by insufficient manpower. Dayu Heavy Industry is very responsible to say: As long as you are a clear-headed user, you can easily control the cobblestone sand making machine regardless of your academic qualifications, so that it can exert its remarkable effect. Despite this, there are some problems in the use of the sand making machine that the user can't figure it out. It is like “the smaller the raw material entering the cobblestone sand making machine, the better?” This problem has some misunderstandings in many customers' minds. As we all know, the size of pebbles is different. When we mined, we use 5-10cm of raw materials. If we have larger particle size, we can use coarse crusher and then put it into cobblestone sander. Why is it 5-10cm? If the particle size of the raw material is smaller, can it not reduce the working pressure of the sand making machine, thereby increasing the output and reducing the loss? In fact, the reason why the cobblestone sand making machine can play an excellent mechanism sand crushing effect is because of the internal pattern. Under this feature, the rotor drives the hammer head to rotate at a high speed, and the cobblestone material in the action area is subjected to impact crushing. If the particle size of the cobblestone material is too small, the chance of encountering the hammer is reduced, and the effect will definitely decrease. After the analysis and research of Dayu Heavy Industry cobblestone sand making machine manufacturer, the pulverization effect can reach the best state when the cobblestone raw material particle size is kept at 5-10cm. Here, the user is reminded that if the raw material contains a small amount of pebbles larger than 5-10cm, as long as the feed port of the sand making machine allows passage, it can directly enter the crushing. If the quantity is large and the particle size is large, the jaw crusher must be used. Broken equipment. In addition, if the user's funds are not under pressure, a rough breaking program can be added in front of the cobblestone sand making machine. This method has a good effect on avoiding loss. sand making machine 制砂机

    The cobblestone sand making machine is a sand making device for crushing pebbles. In the initial stage of the purchase of new machines, there is a period of running-in. In the process of contact, friction and biting of mechanical parts during the running-in period, how can the equipment last for a long time and the economics of the equipment become better? The cobblestone sand making machine has also been run-in at the factory, but the surface of the part is still rough. If you want the normal and orderly work of the sand making machine in the later stage, it is necessary to run it in during the running-in period. For the user, the function and performance characteristics of the sand making machine equipment may not be known in the early stage. Therefore, there will be cases where work efficiency is not high. Did not achieve the desired results. Before the sand making machine equipment is in operation, the operator should have an understanding of its performance characteristics and structural performance. According to the professional guidance of the manufacturer, strict operation specifications are implemented to avoid unnecessary losses. During the running-in period, pay attention to the lubrication work and wear of the equipment, and be careful not to overload. As long as we are familiar with the performance and standard operation of the sand making machine equipment, timely inspection and maintenance of the wear and lubrication conditions can reduce the production cost in the later stage, and also improve the work efficiency and increase the production income.

Causes of jaw crusher bearing heat
The bearing is one of the more important accessories on the jaw crusher. It supports the various structures of the crusher and carries the impact force when the crusher breaks the material. The performance of the crusher directly affects the normal operation and production efficiency of the equipment..Bearing heating has great harm to the normal operation of the equipment. Therefore, pay attention to the temperature rise of the bearing and the noise occurrence of the bearing, and find and deal with it in time.
First of all, check the lubrication state of the shaft, the grease can not be too much or too little, and can not let the bearing work in the state of lack of oil, too much grease will cause the bearing to heat up.According to the standard of the lubrication specification, the grease added to the bearing is 50-70% of the bearing volume to ensure the normal and efficient operation of the crusher.In addition, it is necessary to replace the grease every three months to ensure the grease is clean. It is strictly forbidden to block the oil hole by pollutants.
Secondly, check the tightness of the bearing cap and the shaft. The bolt is too tight, the clearance is too small, and a lot of heat is generated by friction with the bearing. If it is too loose, it will cause the crushing machine body to shake, causing unnecessary load shock to the bearing.The bearing heat is increased and the bearing temperature is increased.Always check the tightness of the upper cover bolts in daily life to ensure that there is a qualified clearance to avoid excessive bearing temperature.
