1.Driving grinder


The main feature of the driving grinder is that the walking speed and direction of the machine are controlled by the mechanical rocker during use, and the replacement of abrasives is controlled by electro-hydraulic, which effectively reduces labor intensity, improves construction standards, reduces abrasive wear and increases machinery
The grinding width and frequency, the weight is relatively large, the pressure of the relative mechanical grinding head is increased, the torque is large, and the linear grinding performance is excellent.


The cutter heads of metal grinding blocks are also different, Arrow Stone Floor Grinding Segment,Rectangle,
Metal Round Grinding Pad Tipssingle arc and other shapes

Advantages: excellent grinding performance, uniform walking speed during operation, better abrasive loss and construction flatness, equipped with vacuum cleaner, can be used for dry grinding construction.


Disadvantages: heavy machinery, inconvenient loading and unloading of the transporter, only used for large-area construction.



2.Double-head counter-rotating grinding machine


The double-head counter-rotating grinder adopts three-phase 380V voltage, power 7-15HP, mechanical speed 150-290r/min, and can be equipped with three-jaw counter-rotating planetary grinding head. The maximum revolution speed of the grinding head is 600r/min and the maximum rotation speed is 1800r. /min. Can be used with
Smooth Grinding Metal Diamond Pads For Suppliers.


General machinery is equipped with frequency conversion speed regulation device. The main function is to adjust the running speed of the grinding head. Different grinding processes should use different speeds. At the same time, the frequency conversion device also has a soft start function and a protection function for the machine. The soft start can not only improve The service life of the machine will also prevent the ground from heating up and overheating during the machine starting process, which will damage the ground.
  
Advantages: During the grinding process of the machine, the grinding traction forces of the two grinding heads can offset each other, and the mechanical operation is relatively easy and stable. The double grinding head cross grinding can avoid the grinding blind zone between the grinding heads. At the same time, due to the operation of the two grinding heads, the increase in width will also improve the flatness of the construction, which can meet the grinding construction of soft ground and effectively improve work efficiency.

Disadvantages: The mechanical grinding head adopts the counter-rotating operation mode, which has poor grinding performance compared with the planetary grinding head and lower efficiency for hard ground. If the planetary grinding head is equipped, the mechanical manufacturing cost is higher.


3.Three-head planetary grinding head grinding machine


The three-head planetary grinding head grinder adopts three-phase 380V voltage, power 7.5-15HP, maximum mechanical revolution speed 400r/min, maximum rotation speed 1500r/min. The characteristic of the three-head planetary grinding head grinder is that the revolution and rotation of the mechanical grinding head have a fixed speed ratio, and the grinding force of mechanical grinding is increased.


Advantages: The machine is equipped with large power, large grinding width, and large grinding force, which can meet the needs of large-area construction. Equipped with vacuum dust holes can be used for dry grinding construction.

Disadvantages: The rotation speed ratio between the rotation and revolution of the three-head planetary grinding head grinder cannot be adjusted mutually, which causes the machine to operate on soft ground with greater traction, which will increase the labor intensity of the construction personnel and reduce the trial of the machine range.


4.Three-head distribution planetary grinding head grinder


The three-head distribution planetary grinding head grinder adopts three-phase 380V voltage and single-phase 220V voltage, power 5-15HP, maximum mechanical revolution speed 500r/min, maximum rotation speed 700r/min. The characteristic of the three-head distribution planetary grinding head grinder is that the revolution and rotation of the machine will adjust the speed ratio through the friction coefficient of the ground, reduce the power output of the machine, and increase the use range of the machine.
  
Advantages: Compared with the double-head counter-rotating grinder, the grinding force is increased, and it has a better light output effect on hard ground. At the same time, it has strong mechanical comprehensive ability. It can be used for polishing and surface treatment by adjusting the pressure of the grinding head.
Disadvantages: The grinding traction of the revolution and rotation of the distributed planetary grinding head cannot completely cancel each other, which makes it difficult to operate the machine on soft ground and increases the labor intensity of the construction personnel.


5.Four-head floor grinding machine


The main feature of the four-head floor grinder is that during the grinding process, the four-heads are cross-polished. The longitudinal and transverse traction forces of the grinding heads can offset each other. The four-head cross-polishing can also avoid the blind zone between the four grinding heads.
  
Advantages: The mechanical operation is particularly easy and stable, and the grinding width is large, which effectively improves the flatness of the construction and meets the requirements of large-area construction. It is equipped with a vacuum cleaner and can be used for dry grinding.

Disadvantages: Due to the non-planetary design of the mechanical grinding head, in order to meet the requirements of 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 remains unchanged.
