Know how to reduce the production cost of packaging paperboard for small and medium-sized enterprises (Part 2)

3. Low energy consumption is the basis for cost reduction.

the energy consumption of paper-making enterprises mainly refers to water, electricity, steam (coal). Paper-making enterprises are large consumers of water, drainage, sewage discharge and energy consumption in the light industry and even the whole industrial production. Energy consumption accounts for a large proportion of the cost. Reducing energy consumption is the basis for reducing costs, and it is also the basic work of enterprises

4. The main measures to reduce the energy consumption of packaging board are:

· save water and basically achieve zero emission. The treatment technology and cost of the middle section wastewater using waste paper have basically passed the standard. As long as the white water is recycled, the water before and after the workshop is used in reverse and the treated purified water is reused, zero discharge can be basically achieved

· for enterprises that produce bleached paper at the same time, the middle water discharged can be supplied to the cardboard production workshop

· the waste paper treatment line of small enterprises should not be large and foreign. Do not exceed the actual capacity too much, too much surplus, increase the installed capacity, and use too large motors

· the equipment with the largest installed capacity due to its small effect and poor use effect should be discarded

· avoid idling the equipment, and avoid that the equipment of pulping and waste paper treatment line does not operate in low concentration according to the process requirements. Avoid "big horse pulling small car"

· where the price of electricity at night is low, more standby slurry storage tanks shall be provided. Sundaram added some suggestions from his tutor Wojciech matusik, an associate professor of electrical engineering and Computer Science (EECS) at MIT; Marc Baldo is also an associate professor of EECS. It is strictly prohibited to "run, emit, drip and leak" steam containers, steam equipment, steam pipelines and valves

· steam return must be fully utilized

5. Unit hour output is the key to reducing costs.

output is the ultimate embodiment of "all the work of the enterprise". Without output, it is empty talk if other work makes a considerable number of bubbles in the sample

stable unit hour output is the basic requirement to complete the total output. Only by increasing production can we increase income. Increasing output is the key to reducing costs

the relationship between output and cost can be seen from the following formula:

unit cost (yuan/ton) = (fixed cost (yuan for the rapid development of green manufacturing industry) x variable cost (yuan)/output (ton)

fixed cost refers to the cost that must be paid normally regardless of the output, including: enterprise management fee (administrative expenditure, loan interest, environmental protection fee, management salary, etc.) Workshop expenses (repair costs, depreciation, spare parts, workshop staff salaries, etc.) are basically unchanged

variable costs refer to the costs that change with the change of output, including raw materials, auxiliary materials, water, electricity, steam consumption, packaging materials, etc. Generally speaking, the output is inversely proportional to the consumption. Relatively speaking, the larger the output, the less the unit consumption, especially the lower the unit coal power consumption

as can be seen from the above formula, because the fixed cost remains the same, even if the unit consumption remains the same, the higher the output, the lower the cost. The main measures to improve the output:

· improve the running time. The paper industry is a continuous production, and the lost time cannot be made up. The running time quota of the paper machine in the past; The long-term machine is 22 hours a day on average, and the round machine is 22 hours and 30 minutes a day on average, including medium and small repairs, parking and washing, excluding major repairs. The more unplanned downtime, the greater the impact on production

· there must be major, medium and minor repair plans and spare parts

· do a good job in daily inspection, lubrication and maintenance. The maintenance workers should come as soon as they are called and can fight when they come

· plan the downtime quota

· there is a strict and realizable reward and punishment system for good or bad output planning

· determine the personnel, position, indicators and scope of responsibilities

· try to avoid and eliminate all accidents

· it is necessary to carry out a variety of team labor competition, such as carpet changing, no broken ends, hourly output, safe production and no accidents

on the premise of ensuring the quality, only by increasing the output and reducing the cost can the economic benefit of the enterprise be improved
