The difference between the crushing method of sand making machine “stone stone” and “stone hitting iron”


The sand making machine is one of the standing machinery for stone crushing and sand making machine. It provides a large number of high-quality sand for high-standard sand, railway, paving, construction, water conservancy and hydropower projects. The equipment mainly uses the hammer body mounted on the rotor running at high speed to crush the material and accelerate the crushing operation of the material by the mutual friction between the materials. There are two ways to break the sand making machine: “stone hitting stone” and “stone hitting iron”. What difference do they have?
1. Stone-rock–installation of upper and lower striking guards on the wall of the crushing machine of the sand making machine, so that the ore material accelerates when the material is accelerated, and the lining layer formed around the material is impacted, rubbed or material and material It breaks at high speed and does not directly contact the metal of the equipment. This way reduces the wear and tear of the parts and prolongs the service life. “Stone stone” is suitable for medium and hard abrasive materials, such as basalt, and the finished product has good grain size, but the powder content is slightly more, which is more suitable for shaping ore materials.
2, stone hit iron - different from “stone hit stone”, the sand making machine in the crushing chamber wall will be replaced by the lower guard plate into a weekly shield, the ore material is directly impacted on the weekly guard plate when the picking wheel is accelerated and thrown The crusher and the crusher collide with the material in the crushing chamber under continuous impact, and the ore material is broken more fully by impact, friction and grinding, and the finished material has smaller particle size. “Stone iron” is suitable for materials with low abrasiveness below medium hardness, such as limestone, etc., and the crushing efficiency is also high. However, due to the impact crushing, the peripheral guard plate is high in grinding, the cost of the wear parts is relatively high, and the finished product shape is slightly poor, which is more suitable for sand making.
The different differences in the way of crushing are important factors that influence the choice of the user. Different user requirements also affect the choice of the crushing method of the sand making machine. Only the right one is right.

What are the cleaning methods for Raymond mill components?


In the production process of raymond mill, its regular cleaning is an important part of maintenance. Reasonable cleaning can improve the use time of accessories, thus reducing wear and improving equipment production efficiency. However, the cleaning methods, methods and methods of equipment are very important. So, what are the cleaning methods for Raymond mill components?
First of all, before cleaning the parts, you need to know the individual parts, the type of parts, and which cleaning method to use, and pay attention to clean the general parts. At the same time, the cleaning requirements of precision parts are high. Pay attention to the way and strength of cleaning, and use soft and suitable tools to avoid damage during the cleaning process.
Secondly, the choice of detergent should be anti-corrosion and moisture-proof. The cleaning agent should not contain any corrosiveness. Before cleaning, it is necessary to consider the material of the parts, select the appropriate cleaning products, and carry out corresponding anti-corrosion measures for the cleaned parts. . Raymond mill accessories are made of steel. In a humid environment, it is prone to oxidative reaction and rust. Therefore, the cleaned parts need to be dried.
Once again, when cleaning the parts, the raymond mill should pay attention to light handling, avoid collision and scratches in the finishing, and order the same type of parts. This discharge can reduce the ease of installation in the later stage. At the same time, special tools need to be cleaned up with special tools.
Then, during the cleaning process, it is important to pay attention to the personal safety of the operators and the protective measures. The premise of cleaning is to protect the physical and mental problems of the personnel, and to properly treat the cleaned wastewater and waste to avoid the surrounding environment. Make an impact.

SBM teaches you how to solve common faults in ultra-fine mills


In the production process, the components of the Ultrafine Mill equipment will inevitably have such failures. Only when these faults are well solved can the equipment be in good working condition, so the main point of this article is to explain the ultra-fine grinding equipment in production. In recent years, SBM has also invested a lot of research on the faults in the process of equipment work. It also made some conclusions on the problem of component failure of ultra-fine mill equipment. Let me introduce you to the following. :
First of all, for the problem of equipment components, the manufacturer’s solution is to check whether the power outlet, power cord, etc. are broken or not, and if there are any problems, it should be solved in time. Otherwise, the power supply can be used and the test machine can be used. jobs;
The second is the problem that the motor does not rotate after the device is powered on. At this time, the wheel is lightly moved by hand. If the rotation indicates that one of the starting capacitors of the device has failed;
Once again, the pressure is applied after the device is energized, and a weak current sound is emitted, indicating that the starting capacitor has a slight leakage. If the current is loud and the motor cannot be started, the starting capacitor is short-circuited;
For the fault problems and corresponding solutions in the production of Ultrafine Mill components, the above summary is clear. In the actual working process, only the maintenance of the equipment can be fine to ensure the working state of the equipment.
