Core requirements for installation of dry granulation machine
Installation work can be roughly divided into three stages: pre installation preparation, installation execution, and post installation verification.
Part 1: Preparation before Installation (Foundation and Environment)
This is the most crucial step. If the preparation work is done well, the subsequent work will be twice the result with half the effort.
Foundation and load-bearing capacity:
Ground requirements: It must be installed on a sturdy and flat concrete floor. The ground should be able to withstand the static load (weight of the machine itself) and dynamic load (vibration and impact during operation) of the machine.
Levelness: This is of utmost importance. Uneven foundation can cause equipment deformation, misalignment of the main shaft, uneven pressure on the pressure roller, resulting in bearing damage, high vibration noise, uneven granulation, and a series of serious problems. The requirement for levelness error is generally less than 0.1mm/m (refer to the equipment manual for details).
Space and Layout:
Operating space: Sufficient space should be reserved around the equipment (usually recommended to be at least 1-1.5 meters in front, back, left, right) for daily operation, maintenance, replacement of pressure rollers and screens, as well as material transportation.
Maintenance space: Special consideration should be given to the extraction space of the roller module and the granulator module, in order to facilitate major repairs and replacement of core components.
Upstream and downstream equipment connection: Reasonably plan the position relationship between the feeding machine (such as vacuum feeding machine, spiral feeding machine) and downstream equipment (such as vibrating screen, elevator, material bucket) to ensure smooth material flow without blockage or excessive drop.
Preparation for public works docking:
power supply
gas source
Environmental Requirements
Cleanliness: The installation environment should meet GMP requirements, with no large amount of dust or corrosive gases.
Temperature and humidity: The recommended ambient temperature is usually between 5-40 ℃. Humidity has a significant impact on materials, and if control is necessary, workshop dehumidification should be considered.
Part 2: Installation and Execution Process
Positioning and leveling:
Mobile: Use a forklift or crane to move the equipment, ensuring the lifting point is correct and avoiding collisions.
Positioning: Place the device steadily on the prepared foundation.
Fine tuning level: Use a high-precision level to measure on the machining reference surface such as the equipment base or main bearing seat. By adjusting the gasket under the anchor bolt and repeatedly adjusting it, ensure that the longitudinal and transverse levelness meet the requirements of the manual. This is the core step of installation, which requires patience and meticulousness.
Fixed:
After leveling is completed, tighten the anchor bolts to the specified torque to ensure the stability of the equipment. Recheck the levelness again to ensure that there is no change during the tightening process.
Public works connection:
Electrical connection: Operated by professional electricians. Connect the power cord to the equipment cabinet to ensure correct phase sequence (for equipment with cooling systems, incorrect phase sequence may cause the water pump or fan to reverse). All cables should be protected using conduit or cable trays.
Gas connection: Use a suitable pressure resistant gas pipe and seal the connection with clamps or threaded sealing tape to ensure no leakage.
Vacuum system connection:
This is the key to ensuring the production environment and particle quality. Connect the dust hood at the discharge port of the equipment to the central dust removal system of the factory or use an independent dust collector.
Ensure tight connections, no leaks, and sufficient air intake to effectively remove fine powder generated during the granulation process.
Docking with upstream and downstream equipment:
Install the feeding machine and downstream feeding equipment, preferably using food grade soft connections at the connection points to ensure sealing and reduce vibration transmission.
Part Three: Post installation Inspection and Debugging
Installation completion does not mean the end of the work, strict inspection and debugging must be carried out.
Mechanical inspection
Electrical and safety inspection
No load trial operation
