High efficiency grinding equipment knowledge (2)
One Development trend of floor grinding machinery
With the continuous development of the floor industry, the demand for large-scale construction and the increase in labor costs have formed a lot of professional floor grinding construction teams. In order to better meet the needs of high-end customers, further improve work efficiency and reduce labor intensity, twelve grinding machines and twelve planetary grinding machines have been developed, which have stable operating performance and high efficiency, and are widely used in stone and floor industries. Due to the rapid increase in the demand for grinding treatment of commercial floors such as underground garages, in order to better meet the construction needs of large areas, driving grinding equipment soon entered the floor industry. In order to meet the grinding needs of the single-pointing super-flat floor of the elevated storage space, a laser leveling grinder was developed in China in 2015.
The development of the overall grinding machinery at the site not only to meet the development of the stone industry, but also to promote the needs of the development of the floor industry, so that the requirements for mechanical properties are becoming higher and higher. Therefore, the pace of research and development of domestic grinding machinery has been accelerated, which has shortened the gap between China's grinding machinery and similar foreign products, and even exceeded foreign products in some aspects.
In the 21st century of economic globalization, the development of China's floor industry and the rapid popularization of its culture, in today's increasingly prosperous floor industry, the original traditional labor-intensive operation mode is no longer suitable for the development of the floor industry. The integration of machinery and equipment, high efficiency, intelligence will become the mainstream of The Times, in order to better meet the market demand, we must introduce high-end technology, strengthen research and development efforts, and further improve the performance of machinery and equipment.
Two Grinding equipment
Floor grinding machine is a set of fast sealing curing agent floor, hardening floor, epoxy floor treatment, stone renovation, concrete leveling, grinding, polishing and other different processes in one of the multi-functional machine equipment. Its conception design basis is: the extension of stone processing machinery; The necessary elements of concrete, cement floor, ground stone slag cleaning, leveling and grinding and polishing functions; Humanized operation and construction requirements; Therefore, the floor grinding machine is a combination of excellent function, remarkable efficiency, reasonable structure, easy and flexible operation, and has become an essential equipment for modern floor grinding process.
1, double head rotary grinding machine
Dual-head counterrotating grinding machine adopts three-phase 380V voltage, power 7-15HP, mechanical speed 150-290r/ min, can be equipped with three-claw counterrotating planetary grinding head, grinding head maximum rotational speed 600r/min, maximum rotational speed 1800r/min.
General machinery is equipped with frequency conversion speed regulation device, the main function is to adjust the grinding head running speed, different grinding processes should use different speed, while the frequency conversion device also has the function of soft start and the protection of the machine, soft start can not only improve the service life of the machine, but also avoid the machine during the start of the ground overheating, so that the ground is damaged.
Advantages: In the grinding process, the grinding traction of the two grinding heads can offset each other, and the mechanical operation is relatively easy and smooth. Double grinding head cross-grinding can avoid the grinding blind area between the grinding heads, and due to the operation of the two grinding heads, the width increases, which will also improve the flatness of the construction, which can meet the grinding construction of the soft texture surface, and effectively improve the work efficiency.
Disadvantages: The mechanical grinding head adopts the rotating operation mode, which has poor grinding performance compared with the planetary grinding head and is suitable for hard ground
The efficiency is low, if equipped with planetary grinding head, its mechanical manufacturing cost is higher.
2, three head distribution planetary grinding head grinding machine
The three-head distribution planetary grinding machine adopts three-phase 380V voltage and single-phase 220V voltage, power 5-15HP, the maximum mechanical revolution speed 500r/min, the maximum rotation speed 700r/ min-three-head distribution planetary grinding machine is characterized by the mechanical revolution and rotation will adjust the speed ratio through the friction coefficient of the ground, reducing the power output of the machine. Improve the scope of use of machinery.
Advantages: Compared with the double head rotary grinding machine grinding grinding force, the hard ground has a better light effect while the mechanical comprehensive ability is strong, by adjusting the grinding head pressure can be used for polishing and surface treatment.
It is difficult to operate on soft ground, which will increase the labor intensity of construction personnel.
Disadvantages: The grinding traction force of the distribution planetary grinding head rotating and rotating can not completely offset each other, resulting in difficult operation of the machinery on the soft ground, which will increase the labor intensity of the construction personnel.
3, three planetary grinding head grinding machine
The three-head planetary grinding machine adopts three-phase 380V voltage, power 7.5-15HP, and the highest mechanical revolution
The grinding force of mechanical grinding is increased when the ratio between the fixed speed and the self-converting speed is changed. 400r/min, maximum rotation speed 1500r/min. The three-head planetary grinding machine is characterized by a mechanical grinding head
Advantages: Mechanical equipped with large power, large grinding width, large grinding force, to meet the large area of construction needs equipped with vacuum dust hole can be used for dry grinding construction.
Disadvantages: The speed ratio between the rotation and revolution of the grinding head of the three-head planetary grinding machine cannot be adjusted to each other.
It leads to a large tractive force in the operation of machinery on soft ground, which will increase the labor intensity of construction personnel and reduce the scope of use of machinery.
4, four head floor grinding machine
The most important feature of the four-head floor grinding machine is that during the grinding process, the four-head cross-grinding, the longitudinal and transverse traction of the grinding head can offset each other, and the four-head cross-grinding can also avoid the grinding blind area between the four grinding heads.
Advantages: The mechanical operation is particularly easy and smooth, and the grinding width is large, which effectively improves the flatness of the construction to meet the requirements of large-scale construction, and is equipped with vacuum dust suction holes for dry grinding construction.
Disadvantages: Due to the non-planetary design of the mechanical grinding head, in order to meet the needs of the hard ground and improve the mechanical grinding force, the unit pressure of the mechanical grinding head is relatively increased, the mechanical weight is relatively increased, and the handling is unchanged.
5, driving grinder
The main feature of the driving grinding machine is that the speed and direction of the machine in use are controlled by the mechanical rocker, the replacement of abrasive is controlled by electric hydraulic, which effectively reduces the labor intensity, improves the construction standard, reduces the abrasive loss, increases the width and power of the mechanical grinding, the weight is large, the relative pressure of the mechanical grinding head is increased, the torque is large, and the linear grinding performance is excellent.
Advantages: excellent grinding performance, uniform walking speed during operation, better control of abrasive loss and construction smoothness, excellent machine automation performance, greatly reducing labor intensity, to meet the requirements of large area construction, equipped with vacuum suction, can be used for dry grinding construction.
Disadvantages: heavy machinery, handling and loading is not convenient, only suitable for large area construction.
