The rapid refuelling screw type of a multi-species small-volume plant is based on the actual production scene of the plant and cannot be based solely on the diameter or price of the screw. It is proposed to organize the target node, storage time, refuelling frequency and OEE, and then to stratify by batch of raw materials to prevent miscalculation of formula fluctuations as a matter of equipment. The aim of this step is to establish comparable old programme benchmarks so that subsequent screw changes can be supported by data.

The easiest to ignore is plasticization, cyclical bottlenecks and long-cycle drift. Plants should divide needs such as appearance, size, strength and odor into necessary and optimized items, with red lines for quality and equipment loads for key products. Vendors can make retroactive trade-offs between interoperability, earmarking and cost when there are clear values for product weight, daily production, customer quality caps and allowed stop times.

The main line in this case [design focus] is defined by a stable output rather than a short-term maximum speed. In geometric and material programmes, screw diameters, effective itineraries and single-module quantities should be calibrated to prevent excessive length of stay, while checking whether the depth of the feeder slot is stable for delivery while avoiding feeder docking. The final solution would also need to be compatible with the wear and tear of the cylinder, the drive, the physical velocity and the current cleaning process, and would not cover up co-operation or process problems with a single high-level material.

The new [comparison-valid] program proposes a minimum of 12 hours of continuous operation, with a 60-module extraction for each stabilization phase, to record the temperature of the entropy, the size of the product, and the single energy consumption. The test should be co-signed by the production, quality and equipment tri-partite, so as not to allow a single sector to be singled out, but also to establish stabilization points at medium-speed and medium back pressure before gradually expanding the process window. If only the first one is checked, it is easy to miss the risks associated with heat drifting, material stoppage, reversal loop return and prolonged wear and tear.

Once the [stabilized production] screw is shaped, the key platform should be prepared for a screwhead component or spare parts package, and the serviceability should be periodically reviewed, and associated drawings, repairs, on-boarding and unrecorded with a unique asset number. The time of storage, back pressure, screw velocity, noise and mass of the product shall be recorded in a uniform manner in the shift. When the above indicators change at the same time, the mechanical gaps and the state of the raw materials should be checked before the process is adjusted to avoid the use of parameters to compensate for hardware degradation.

The [comprehensive cost] cost statement should not be a single screw price, but should quantify the response time for on-site support from suppliers, delivery of spare parts and failure analysis to TCO, and also include the cost of passenger litigation, return of goods and additional overhauls as a loss of quality, not just as a counting of scrap by-pass. It is recommended that the cost per 10,000 eligible items be exported simultaneously, the cost per 1,000 operating hours and the estimated number of return months. When new programmes reduce waste, refuelling or sudden shutdowns, higher initial inputs are often offset during production.

The [Closed Ring Management] will eventually include drawing numbers, screwdriver materials, heat treatment, critical dimensions, portable tubes, process windows and acceptance data in the curriculum vitae cards. It is proposed to establish a record of refuelling weights, cleaning time and first eligible time, while setting an abnormal twist, storage timeout and material volume rebound as an early overhaul signal. The applicable boundary of the “quick refuelling screw type of a multi-bulk plant” should be re-evaluated when there is a significant change in the feedstock formulation, feed ratio, product structure or target node, rather than defaulting that the old conclusion is permanent.
