Analysis Of The Advantages And Disadvantages Of Automatic High Speed And Low Speed Tablet Press (2)
Dec 08, 2021
Table 2: Comparison table of functional indicators of ZP-83D high-speed press and ZP35 low-speed press
Functions and indicators |
ZP-83D high-speed chip press |
ZP35 low-speed chip press |
||
tightness |
Materials enter the hopper through a closed conveying system, taking effective means to prevent dust from flying. The pressed tablet enters the packaging process through the sheet and metal detection, and the whole process has good sealing ability. |
The process of the pressure plate from the feeding, feeding and other links are open, has not achieved sealing, resulting in dust flying between the pressure sheet. |

In the production |
High production |
796,000 tablets, / hour (maximum labor) |
Low production |
150,000 Tablets, / hour (maximum production) |
Conducting pressure |
high pressure |
1. Both main and prepressure provide a maximum of 100 kcal. 2. And the main pressure and pre-pressure can be directly displayed on the real color touch screen. 3. The main pressure and pre-pressure adopts the German Teyadi gravity sensor, the pressure check and deletion is accurate and direct, to ensure the stability of the pressure, and easy to ambiguity. 4. Can easily suppress the round, large, special, special, single face lettering, double layer and so on. |
The pressure is small |
Main pressure can provide up to 60 thousand cattle pressure, it is difficult to suppress large diameter, chewing pieces, or less formed materials. |
major structure |
Machinery, support |
1. The compressor frame is a four-column structure, and the four columns, the base plate and the roof plate form a rigid body. The force generated by the machine load work counteracts each other, the center of gravity is low, the smooth operation, and effectively realizes the overload protection function. |
Machinery, support |
Equipment operation vibration, high noise, overload alarm is not sensitive. |
|
|
2. The hydraulic system is cancelled, and the maintenance of the main pressure and prepressure pressure is realized by the high strength support system, which completely avoids oil leakage and reduces the pollution of drugs |
|
|
Method of feeding |
Forced feeding |
1. Double-layer three-paddle forced feeding device, the upper lobe swing to increase the mobility of the powder, balance the powder density, the following two leaves are used for filling and meter, to ensure the uniformity of filling. 2. The automatic servo motor controls and adjusts the internal guide rail, and controls the filling depth to ensure the high accuracy of the chip difference. |
Free falling material |
The filling is unstable, and the sheet weight is very different. |
Leap Jin way |
Fully automatic centralized lubrication system interconnected system |
1. Adopt the central divided automatic dilute oil cabinet sliding system and automatic dry oil cabinet sliding system. 2. The central divided steamer automatic sparse oil cabinet sliding system, can set the cabinet sliding cycle on the touch screen, with the alarm of insufficient cabinet sliding oil. 3. Automatic dry oil cabinet sliding system, to ensure that the bearing and other positions of the cabinet slide, greatly reduces the difficulty of maintenance. 4. The cabinet sliding cycle can be adjusted on the touch screen, and the dry milge sliding system also slides on the top part, which reduces the phenomenon of all thin oil and slag into oil thrown to the disk, and reduces the possibility of polluting the medicine powder. |
Oil cup lubrication |
Artificial oil injection, equipment is prone to insufficient cabinet slip, parts damage or cabinet slide through, drug pollution phenomenon. |
Get rid of bottom function |
Perfect function |
1. With start, stop batch elimination. 2. Process approval bottom, 3. The function of single film. |
not have |
The control system is simple and does not function to remove negatives. |
Safety protection function |
security guard |
1. Main motor overload protection. 2. Up and down overtight, pressure overload protection. 3. Material supply is insufficient for protection. 4. The cabinet slide oil is not adequately protected. 5. Fill with 40 alarms such as the upper and lower limits. |
not have |
Does not have a reliable security protection function.Such as single value pressure super difference, too large filling, too tight impulse and so on. |
mode of operation |
No hand brandishing |
1. Control with a 10.1-inch touch screen. 2. Automatic control of the fully automatic servo system motor. 3. Main pressure, pre-pressure and ironing measuring mechanism, and accurately control the position of each actuator. 4. Hand-free swing operation. 5. The equipment host and the electric control system are separated, keeping the electrical system away from dust and vibration, extending the service life, and and the safety and health coefficient are greatly strengthened. |
Hand brandishing |
Hand swing control, adjust the position of each actuator with experience |
control method |
PCC |
1. Using the Siemens industrial computer FCC control system, powerful, faster, larger answer, reliable quality. 2. Compliance to 21 CFR PART II. 3. Electrical components are repeatedly used by internationally famous brands to ensure the reliability and stability of the electrical control system. |
manual control |
Use a button switch for low automation. |
In the plate material |
stainless steel |
Using 2Crl3 stainless steel slag and light quenching, the surface hardness can reach above HRC55, with good hardness, wear resistance and corrosion resistance. |
iron casting |
The use of universal pity iron, in the Zheng wet ring grave, the plate is easy to rust, polluting drugs. |
die life |
long life |
The upper and lower molds are made of 6CrW2Si and medium flushing molds Cr12MoV material, high mold precision, long service life. |
Short life |
Made of bearing steel, with low mold precision and short service life. |
Conclusion: It can be seen in Table 2 that high-speed compressor is significantly better than low-speed compressor in many aspects of functional indicators.
