What are the common stone crushers?


The stone crusher is a device specially used for crushing large stones into stones. Common stone crushers include jaw crushers, hammer crushers, impact crushers, impact crushers and so on. These stone crusher are widely used in stone crushing and stone processing, each with its own advantages. Under different production requirements, different crushers can be selected.
The jaw crusher is also called the tiger’s mouth, because it is a crusher that simulates the two-inch movement of the animal to complete the material crushing operation. The equipment can be regarded as the equipment used in the crushing of stone materials, because the large stone first needs to be coarsely broken by the jaw crusher, the crushing ratio is large, the efficiency is high, the structure is simple, and the crushing compressive strength is below 320Mpa. Stone material has great advantages in stone crushing.
The hammer crusher is a section of crushing crusher that directly crushes materials with a large particle size of 600-1800 mm to 25 or less. Generally used as secondary crushing, mainly relying on impact energy to complete the material crushing operation, the equipment is suitable for medium-hard materials, such as limestone, slag, coke, coal and other materials in the medium and fine crushing operations.
The impact crusher appears much later than the smashing. It is the main fine-breaking equipment, and the new crusher designed on the basis of smashing. Counter-breaking can handle materials with a length of 100-500 mm or less, and the compressive strength can reach 350 MPa, which has the advantages of large crushing ratio and cubic particles after crushing. It can simplify the crushing process and make the three-stage crushing into two sections or a section of broken.
The impact crusher is generally called a sand making machine and plays an irreplaceable role in various fine ore crushing equipment. It is an effective, practical and reliable stone crusher. The equipment is suitable for artificial sand making of stone pebble, pebbles, limestone, granite, basalt, diabase, andesite. It has the advantages of shaping function, cubic shape and high bulk density. It is essential for the production of mechanical sand. device.

What is the quality of the mechanism sand produced by the sand making machine?


We all know that the sand making machine is used to produce sand for construction. The quality of the mechanical sand produced by the sand making machine directly affects the quality and price of the product. Then, what is the quality of the mechanical sand produced by the sand making machine?
To produce machine-made sand, it is impossible to rely on a sand-making machine. What is needed is a sand-making production line to complete the production of machine-made sand. Then, the quality of the mechanism sand is related to the equipment of the whole sand-making production line. Only when all the equipment of the entire sand production line meets the requirements can we produce the required mechanism sand.
The machine-made sand production line is composed of a combination of a vibrating feeder, a crusher, a sand making machine, a vibrating screen and a tape conveyor. Among them, the crusher, sand making machine and vibrating screen determine the quality of the mechanism sand.
The raw material is first crushed by a crusher into a sand that can be used for the sand making mechanism, and then crushed and sanded by a sand making machine. Finally, the required particle size is selected through a screening device to obtain the desired mechanism sand.
Characteristics of machine sand:
Although the solid performance of the machine-made sand is slightly worse than that of the river sand, it still meets the standard superior product index, and there is no problem in the use of ordinary concrete.
In the process of engineering construction, sand and gravel as an important part of concrete structural materials, its quality has a significant impact on the quality and durability of the entire project. Under the premise of meeting the performance index of sand, the economical and feasible scheme is adopted, which not only meets the construction quality requirements, but also effectively controls the production cost. Therefore, in areas where natural sand resources are scarce, it is not only feasible to use the mechanism sand construction. Its comprehensive benefits are also significant. At the same time, in the use of machine sand, it is also possible to carry out research and experiments on the discipline of building materials, accumulate experience and lay the foundation for the development of the discipline.

The reason why the granite ore mill suddenly crashed


In the production of granite ore mills, equipment problems occur due to prolonged grinding. Therefore, it affects the normal operation of the granite ore mill to a certain extent. In particular, the phenomenon that the equipment suddenly locks up not only affects the construction period, but also reduces the milling efficiency. Then, today Xiaobian will introduce the reason why the granite talc grinding mill suddenly crashes.
1. Before the granite ore mill is fed, the raw materials are not inspected, resulting in the entry of non-metallic substances with high hardness into the grinding chamber, resulting in the phenomenon that the grinding chamber is stuck, and the granite ore grinding machine is produced. Suddenly crashed. Therefore, before the operation, the material needs to be sieved to properly grasp the hardness of the abrasive material.
Second, when the particle size of the granite is too large, the difficulty of crushing and grinding the equipment will increase. This will extend the residence time of the granite ore mill in the grinding chamber and also increase the wear of the material on the grinding rolls and the grinding ring. Once the material is piled up on the basis of insufficient grinding, it is easy to cause the equipment to suddenly crash. For this phenomenon, we should correctly control the feed size of the material.
3. In the production of granite ore milling machine, when the operator feeds the equipment unevenly, the grinding cavity will be broken, which will lead to excessive feeding and gather in the grinding cavity to make the grinding cavity. Excessive aggregates eventually led to a sudden collapse of the granite raymond mill. Therefore, the operator should feed the equipment at a uniform speed.
Fourth, the user wants to ensure the normal operation of the granite ore mill, and regularly add and replace the lubricant during the operation. In the case of failure or contamination of the lubricating oil, the friction between the components will increase and the speed of the main engine will be slowed down, resulting in a sudden crash of the granite ore mill. Therefore, good lubricants can prevent important factors in equipment crashes.

How to improve the working efficiency of stone sand making machine


Nowadays, consumer shopping is increasingly seeking personal experience. In the past, the salesperson’s model of pursuing intent customers has become less popular. Shanghai SBM as a mining equipment manufacturer that pays attention to users’ experience, our sales theme also tends to “you just need, I just have, and professional.” Today’s Xiaobian introduces the stone sanding machine equipment produced by the company, including its scope, advantages, types and prices. If you need it?
With the drying of natural sand, construction, road, railway, water conservancy and other industries have used artificial sand to replace natural sand. Therefore, the demand for stone sanding machines is quite large. Under this background, Shanghai SBM developed and produced A special stone sand making equipment. It can excavate most of the stones on the mountain (extra-hard), processing like limestone, bluestone, marble, etc. After all, the finished sand can be comparable to natural sand in terms of grain shape.
Shanghai SBM sand making machine is different from the typical impact sand making machine. It uses sand hammer to impact sand. It is commonly called hammer sand making machine or double rotor sand making machine. It is used in the mechanism sand production line. The customer response is also good. The advantages of this type of equipment are mainly manifested in three aspects.
1. The structure is simpler and more humane. Firstly, the casing, the hammer head, the two rotors and the sieve plate are included. The investigation door is arranged under the sand making machine, and the condition of processing the stone can be observed at any time to facilitate the maintenance of the equipment.
2. The feed size is larger. The feed size of a typical sand making machine is usually around 50 mm, and the stone sand making machine can accept a feed with a particle size of 150 mm or even 250 mm. This shows that the stone between 50mm-250mm can avoid the crushing process and reduce equipment investment.
3. The hammer of the primary working component is made of high hardness and good wear resistance. The long service life is used, which reduces the economic and time cost of replacing parts and directly improves the customer’s profit rate.
