Installation of TGM-Mill

Preparation Before Installation of TGM-Mill

Before installation of TGM Series Super Pressure Trapezium Grinding Mill, the mill should be properly maintained if TGM Series Super Pressure Trapezium Grinding Mil is not installed at once, and kept under roof to prevent sunlight, rain. The antirust grease is supposed to be applied on the exposed surface of the mill. To set up rules for the mill is highly suggested.

The plant should be equipped with suitable workshop, that means there should be enough height and space for installation in the workshop.

The foundation should be made according to actual situation with high grade cement according to foundation drawing, then prebury the braiding pipe for cable chute. When the cement foundation is made strong, there should be enough time for a curing cycle (generally at least 15 days).

Steps should be kept in the foundation pit.

The hoisting equipment of 5-15 t should be equipped in the installation site for installation and maintenance.

The site should also equip the three-phase four-line 400V/50Hz power supply.

The light is also necessary to keep the working site bright.

The main parts like the transmission part, roller, oil tank for classifier, etc should be cleaned and washed if there is a period of six months from leaving factory to operation. After that, enough lubricating oil or grease should be filled in the transmission parts.

Installation of TGM-Mill

• TGM Series Super Pressure Trapezium Grinding Mill Installation of blower.
• TGM Series Super Pressure Trapezium Grinding Mill Installation of bucket elevator.
• TGM Series Super Pressure Trapezium Grinding Mill Installation of jaw crusher.
• TGM Series Super Pressure Trapezium Grinding Mill Installation of feeder.
• Install the cyclone classifier, bag filter to the specific position according to the installation drawing, and then connect the pipes.
• The electric control panel should be installed and fixed in a suitable place. Then connect the wire reliablly.
• The electric accessory and electrical joints of TGM Series Super Pressure Trapezium Grinding Mill should be reliable.
• The pits for mainframe, jaw crusher and bucket elevator should be covered with strong wooden boards.

Trial-run TGM-Mill Without Load

Check whether the earth wires for equipments are safe before equipments trial-run starts, and whether there are protective covers installed in the transmission parts.

1. The rollers should be tightened by steel wires when trial-run the mainframe without load to avoid the collision between roller and ring. The direction drawing of mainframe and classifier is shown in the drawing.

2. The big and small angle gear of classifier should operate steadily without abnormal noise, and the lubrication oil should be smooth. 3. Start the blower after closing the valve, and then open the valve after the equipment operates normally. Check the rotating direction, there should be no abnormal noise or vibration.

4. Before trial-run the jaw crusher, tighten up the bolts and connecting parts, check the lubricating condition. Move the belt wheel by hand, start the trial-run without load after confirming that side movement is without any resistance. The continuous operation of the trial-run should not exceed one hour, and there should be no impact, noise, oil leak in the seal, and without swing of flywheel and belt wheel, loose or tight phenomena.

5. The swing and current of electric-switch box should be steady.

6. Measurement of the noise under the condition of zero loading: put a commen sound level caculator in the place which disctances the gabarit of the maiframe base seat for 1m and 1.5m in the height. The result is not below the average value of 4 point, A soud pressure value.

Trial-run TGM-Mill With Load

1. After trial-run without load, every part of the machine is qualified for normal operation, and then the trial-run with load shall start.

2. The trial-run with load should last no less than 8 hours.

3. The mainframe should work normally and there should be no abnormal noise or impact vibration in the transmission parts.

4. The highest temperature of rolling bearing of mainframe and lubricating oil should not exceed 80℃, while rising temperature should not exceed 40℃.

5. There should be no air leak in the pipes and joints of flange.

6. Capacity of mill should meet the regulated requirement.

7. To adjust the size of final product to meet the requirement, the rotating speed of classifier can be adjusted.

8. To meet the output size of jaw crusher, the discharging size should be adjusted. Also the rising temperature of bearing should not exceed 70℃.

9. The swing and current of feeder should be steady, and feeding amount should meet the requirement.

10. If the trial-run without load and with load are qualified, tighten the parts once again, and then put it into normal operation.
