Install grinding discs of different mesh numbers (currently mainly 20#, 36#, 60#) for grinding as needed. However, using an angle grinder for grinding has the following disadvantages:

1. During construction, workers need to squat to work, which is labor-intensive and low-efficiency. 2. Since it is difficult to connect the vacuuming equipment during the construction of the angle grinder, the dust is large during the construction process, which pollutes the environment and damages the health of workers.

3. At the same time, because the angle grinder uses its series motor, the load capacity is poor, and it often cannot withstand the pressure of contact with the ground during grinding, resulting in excessive current and the motor is easily damaged.

4. When manually operating the angle grinder to grind the ground, the grinding disc and the ground are often in partial contact, and the grinding disc is unevenly stressed, so the damage is very fast, and the consumption of the grinding disc is very large.

Therefore, in order to improve the above situation, some engineering teams try to install sanding sheets on the ground grinding machine to grind the middle coating batch scraper, which not only overcomes the above-mentioned defects of the angle grinder, but also greatly improves the work efficiency. In particular, the design and development personnel of Shanghai Jingzhan Electromechanical Co., Ltd. have accumulated more than ten years of experience in construction and use of equipment and independently innovated. They have designed and developed a three-head multi-purpose ground grinder. The machine is equipped with three knives that are the same as the angle grinder. The seat, so that all the knives and grinding discs that can be installed on the angle grinder can be used on the three-head machine. At the same time, an alloy cutter head specially designed for the three-head machine is also designed, so that it can grind the cement concrete in the same way as other grinding machines.

The design idea of the three-rotor multi-purpose ground grinding machine: strive to be people-oriented, improve the labor intensity and working environment of the staff.

The main structure of the three-rotor multi-purpose ground grinding machine: an AC motor is used to drive the three rotating grinding heads at the same time through the pulley group or gear group, and the whole machine is equipped with a dust collector. The three grinding heads can be installed with multi-blade alloy cutter discs to grind cement floors; universal angle grinder sand discs can be installed to grind the bottom coating; nylon brushes or bristle brushes can be installed to clean the ground; A wire brush can also be installed to remove rust from the steel plate. Since the whole machine is equipped with a vacuum cleaner, dust-free construction is realized during the construction of the floor coating. The rear of the equipment is also equipped with front and rear adjustment and height adjustment devices of the wheel, so as to be adjusted according to different use needs.

Compared with the previous similar equipment at home and abroad, this machine is light and fast, with high work efficiency, reducing labor intensity and improving the working environment; realizing multi-purpose of one machine and improving the utilization rate of equipment.

The main technical advantages of the three-rotor multi-purpose ground grinder: The three-rotor multi-purpose grinding machine is equipped with a multi-blade alloy cutter head. When grinding cement, terrazzo or hardened wear-resistant floors, its effect reaches or exceeds the level of similar foreign equipment.
