High speed tablet pressA final mixing process that effectively handles the second stage mixing process, increases the capacity of the internal mixer, reduces costs, and improves quality. The internal mixer and batch mixing process are still the pillars of today's mixing technology. However, because this batch mixing process is always discontinuous, an independent second stage final mixing process is often necessary, in which sulfurizing chemicals are usually added at low temperatures.
High speed tablet press provides a visual understanding of the wear and tear of vulnerable parts. Due to its easy opening, the wear level of threaded components and the inner lining of the barrel can be detected at any time, allowing for effective maintenance or replacement. It will not be discovered only when there is a problem with the extruded product, causing unnecessary waste. Reduce production costs. When manufacturing masterbatch, it is often necessary to change the color. If it is necessary to change the product, open the open processing area within a few minutes. In addition, the mixing process can be analyzed by observing the melt profile on the entire screw. High speed tablet press: Currently, ordinary tablet presses require a large amount of cleaning material for color replacement, which is time-consuming, consumes electricity, and wastes raw materials. The split high-speed tablet press can solve this problem. When changing colors, it only takes a few minutes to quickly open the machine barrel for manual cleaning, which can save costs by using less or no cleaning materials.
High speed tablet press improves labor efficiency. During equipment maintenance, ordinary tablet presses often need to first remove the heating and cooling systems, and then extract the screw as a whole. However, the split twin-screw does not need to be used. Just loosen a few bolts, rotate the worm gear box handle device to lift the upper half of the barrel, and then open the entire barrel for maintenance. This not only shortens maintenance time but also reduces labor intensity.
The change of mixture for each batch of high-speed tablet press is very common, and additional operations during the mixing process, such as storage, weighing, and cutting of masterbatch, are also required.High speed tablet pressThe turntable is a circular disc with evenly distributed punch holes and middle mold holes around it. When it rotates under the drive of the spindle, each punch moves up and down along the curved guide rail, thus completing the pressing process. The turntable is the main working component of the tablet press. During continuous operation, common faults and their analysis and solutions are as follows:
(1) Long term wear of the punch hole or middle die hole may cause the coaxiality of the two holes to not meet the requirements: During use, the punch hole and middle die hole may experience different axis phenomena due to varying degrees of wear, which increases the frictional resistance of the punch rod moving up and down, and in severe cases, may lead to the inability to press the tablet normally. If the wear of the high-speed tablet press is not very severe, its coaxiality can be restored by reaming the rod hole with a reamer, but if the wear is severe, the turntable needs to be replaced.
(2) The upward movement of the turntable affects filling or dispensing: The upward movement of the turntable is generally caused by the loosening of the taper locking block that fixes the turntable, which can be solved by tightening the taper locking block. If there is a problem with the fastening screws, they should be replaced immediately.
(3) The loosening of the top wire of the middle mold causes it to move up, and the high-speed tablet press damages the feeder: the middle mold moves up, mostly due to the loosening of the top wire of the middle mold. Tightening the top wire of the middle mold can solve the problem. The top wire of the middle mold is a vulnerable part that cannot tighten the middle mold due to long-term wear and tear, and should be replaced in a timely manner.
The high-speed tablet press is mainly a device composed of two interlocking screws inside an "8" shaped cylinder, which is different from a single screw extruder. The conveying in a single coal rod extruder mainly relies on the frictional force generated between the material and the barrel, while the tablet press is a forward displacement conveying machine that has the effect of forcibly pushing the material forward. On the other hand,High speed tablet pressAt the meshing point of the two screws, there is also a shearing effect on the material.
