hardware

Operation panel

Siemens operation panel with 10.1-inch color display is used to control and monitor the rolling process. Connect the panel to the control unit via the MPI bus cable. Connect the panel to the equipment bracket (rotate the fixed range position)

Programmable logic controller (PLC)

Install a standard Siemens S7-1200 PLC

The device is equipped with a permanent memory, without the use of batteries.

Frequency converter (VFD)

Siemens Micromaster G120 inverter with integrated control device is used to control the speed of the drive device. A grade filter is used to ensure safe operation in key laboratories and market facilities.

Access control

The access control of the equipment operation panel is set, so only after confirming the identity can you change the process parameters or make technical adjustments to the equipment. Access control means that only authorized personnel within the area of ​​responsibility can access the operation panel (name and password entry is required). Each user belongs to a user group and has set access rights to the system. This avoids unauthorized changes to the granulation parameters or the initiation of uncleared process steps.

Equipment operation

Automatic operation

Automatic operation is a normal production mode. The equipment starts and stops in an automatic sequence. In this mode, an interlocking system is used to protect the equipment from damage.

Manual operation

During equipment maintenance. Each device may need to be operated separately. Can be achieved in manual mode. In this mode, there is no need to activate the interlock function of the device. Functional components, such as hydraulics, are in semi-automatic operation mode, which facilitates operation. Production in this mode of operation is not allowed.

Setting mode

In this mode of operation, the measurement / calibration of the pressure roller gap can be performed, and even when the equipment cover is opened, the hydraulic system will not be closed.

Device parameters

This item includes all setting parameters of the device. Examples include start and stop delays, alarm limits, operating time series, used to provide signals for necessary maintenance, or pressure roller gap control parameters.

Option

Raw material hopper with lid

In order to integrate AFX 280 Pharma into a production facility and connect it with others. We also provide 3-inch quick-fit connectors and 1.5-inch quick-fit connectors. (3 inch quick connector can be connected with the material level device, in the case of automatic feeding)

Material is probe (option)

The level probe can display the lowest level in the feed hopper, for example, it can be used to control the feed of raw materials.

Pressure roller negative pressure cooling (or positive pressure)

A rotary interface device installed at the free shaft end is used to pass the negative pressure of cooling water from the customer's existing water supply network through the pressure roller. Use a valve to control the flow of water.

The cooling water consumption is about 120 litres / hour.

Granulator screen

Depending on the product, the granulator can be equipped with different screen inserts.

The following alternatives are available:

◆ Wire mesh screen

◆ Square sieve

◆ Round hole screen

Chute with separation function for detecting leaking material of seal

For standard equipment, separate the leaked material from the pressure seal of the pressure roller. Materials from process steps can be collected into separate bins or other storage items. The chute can be replaced by a chute that does not have the function of detecting the leakage of the sealing material. In this structure, the leaked material will be discharged together with the particles.

Sealed air control

In order to control the sealing air at the shaft penetration hole, after the equipment is operated for 12 months, the seal at the shaft penetration hole needs to be replaced

Commissioning with product

The trial operation of the equipment with products will be carried out at the customer's site.

Electrical (option)

Pressure roller gap measurement / indication

The actual pressure roller gap can be measured by the position sensor and monitored by the control panel. The display accuracy reaches `0.1mm.

Pressure roller gap control

The measured value of the roller gap is used as the actual data of the roller gap control. In the PLC, a PID controller is used to activate the preset rated and actual values. The output value of the controller will affect the speed of the feed screw. If the pressure roller gap is too small, the screw speed will increase until the desired pressure roller gap is reached. However, if the roll gap is too large, the controller will reduce the feed screw speed until the desired roll gap is reached.

With this device, changes in bulk density can be compensated.
