The entire unit is equipped with vibration-damping feet. During installation, ensure proper layout and sufficient operating space. Equipment Operating Instructions Before conducting a trial run, carefully inspect the following items: 1. Verify that the local power supply parameters match those specified in this manual, and confirm that all electrical components are correctly and securely connected. 2. Check all connections for looseness; if any are loose, tighten them promptly. 3. Confirm that the gearbox contains the correct lubricant and that the oil level is adequate. Use medium‑pressure gear oil N150 or another high‑quality gear oil of similar viscosity. The oil level should reach the upper mark on the gearbox’s oil dipstick. 4. Manually rotate the coupling connecting the main motor to the gearbox in a clockwise direction for at least two full revolutions. The rotation should be smooth and effortless. 5. Ensure the main motor rotates in the correct direction: when viewed from the head end, it should turn clockwise. After completing these checks, proceed with the trial run of the main unit. The key steps are as follows: 1. Increase the temperature of the main unit; the specific temperature varies depending on the material being processed and should be set by the user. Once the desired temperature is reached, maintain it for 0.5–1 hour. Monitor the temperature control system during heating to ensure proper operation. 2. Verify that the cooling water system is functioning normally and check for leaks. If any leaks are detected, address them immediately. 3. After completing all the above steps, begin rotating the screw. Do not feed material yet; gradually increase the screw speed to approximately 40 r/min and run the machine idling for about 4–5 minutes. Observe whether the equipment operates smoothly. If any abnormalities occur, stop the machine immediately, rectify the issue, and then restart. Gradually increase both the screw speed and the feed rate until the desired production capacity is achieved.

Equipment Installation

This equipment can be installed on a pre-cast concrete foundation or placed directly on a level, stable surface. The entire unit is equipped with vibration‑isolating feet.

During installation, ensure a well-organized layout and leave adequate clearance for operation.

Equipment Operating Instructions

Prior to the equipment’s trial run, the following items shall be inspected one by one.

1. Verify that the on-site power supply parameters match those specified in this manual, and ensure that all electrical components are properly and reliably connected.

2. Inspect all connection points for looseness; if any are found, tighten them promptly.

3. Check that the gearbox contains the correct lubricant and that the oil level is adequate. Use medium‑pressure gear oil N150 or another high‑quality gear oil of similar viscosity; the oil level should reach the upper mark on the gearbox dipstick.

4. Manually rotate the coupling connecting the main motor to the gearbox, ensuring it turns clockwise for at least two full revolutions; the rotation must be smooth and flexible.

5. Verify that the main motor is rotating in the correct direction: when viewed from the head end, it should rotate clockwise.

After completing the inspections of the aforementioned items, a trial run of the host unit may be conducted. The main steps are as follows:

1. Increase the host temperature; the specific temperature varies depending on the material and should be set by the user. Once the host temperature reaches the set value, maintain it for 0.5 to 1 hour. During the heating process, carefully monitor that the temperature control is functioning properly.

2. Verify that the cooling water system is functioning properly. Check for leaks and, if any are present, address them promptly.

3. After completing all the above steps, you may begin rotating the screw. Do not feed material at this stage; gradually increase the screw speed to approximately 40 r/min and run it idling for about 4–5 minutes, observing whether the equipment is operating normally. If any abnormalities are detected, stop the machine immediately to troubleshoot and resolve the issue, then restart it.

Gradually increase the screw speed and feed rate until the desired production rate is achieved.
