Not only choose the right material for the material, but also the food control systems. An example is the automatic funnel filling control. If the container is filled too frequently, the controller will need less time to measure the weight loss, which can affect the accuracy of the loader. On the other hand, if the filling level in the hopper falls too low, the sudden pressure of the material falling into the hopper during filling may cause the material to flow through the screw, especially for low density pulps. and slightly fluidifying materials. Since this material flow falls into the automatic screw feeder price, this leads to a temporary increase in the load of the motor, which leads to an increase in the torque in the control screen of the extruder. These torque peaks must not exceed 100% of the available torque of the extruder. Otherwise, the safety latches will stop the extruder to avoid overloading. As a result, the normal operating torque of the process must be kept lower to make room for these possible peaks.
The increase in efficiency with the optimization of the feeding system can be calculated by the increase in productivity. Table 1 shows an example of its calculation for a 70 mm twin screw extruder, which processes a automatic screw feeder price with a profit margin of 10 [/ kg]. In this example, a feed that experienced an increase in filling was replaced with another one more suitable for the material, which increases the flow from 2,000 kg / h to 2,300 kg / h (4409 to 5,070 lb). / h). The result is an additional annual benefit of $ 180,000, more than four times the cost of the new sender. In addition, as the degree of filling of the twin screw extruder increases, the specific mechanical energy supply for the material increases. This means an energy saving of 5% or 138 automatic screw feeder price / year.
After the feed system has fed the material to the automatic screw feeder price, it must be directed downstream to the feed area. The flow is limited if the entrance area does not have sufficient capacity to transport materials. The transport capacity of the feeding area is determined by the free area of ??the twin screw and the inclination of the screw elements in that area, as well as the speed of the screw and some specific parameters of the product.
The free cross section of the automatic screw feeder price is fixed in a standard twin screw extruder. Extruders with a greater external diameter / inner diameter ratio have a larger free area. This must be taken into account when buying a new extruder. The parameters of the product are related to the selection of raw materials. Changes are often complicated for reasons of purchase or product quality.
The parameters that can be optimized in an existing machine are, therefore, the pitch of the screw elements and the speed of the screw. An increase in screw speed usually leads to a greater input of energy into the material. This increase in energy can be partially compensated by increasing the feed rate. However, this increase tends to be trained by increasing the speed of the screws. This leads to a higher melting temperature which, among other disadvantages, can lead to problems with granulation or product quality.
In conventional polymerization processes, there is a melting zone comprising a section of mixing blocks that are completely filled with polymer. Since this section of the automatic screw feeder price is completely filled, entrained air can not pass through the molten polymer downstream of the molten seal. In conventional polymerization processes, there is a melting zone comprising a section of mixing blocks that are completely filled with polymer. Since this section of the extruder is completely filled, entrained air can not pass through the molten polymer downstream of the molten seal. Instead, it must escape through the nearest upstream opening, which is normally the feed opening . As a result, there is a competitive flow of raw materials and effluent air.
