Trend analysis to find a root-cause of an abnormality [Example: High temperature of VRM bottom bearing]

Image
Analyzing the high temperature of the VRM (Vertical Roller Mill) separator bottom bearing using trend analysis involves systematically monitoring and interpreting temperature data over time. This process helps identify patterns, root causes, and potential corrective actions to prevent bearing failure and ensure the smooth operation of the VRM. Steps to Analyze VRM Separator Bottom Bearing High Temperature through Trends 1. Data Collection Temperature Monitoring: Install temperature sensors on the VRM separator bottom bearing. These sensors should provide real-time temperature data, which is logged and stored in a centralized data system (e.g., SCADA, DCS). Data Logging: Ensure that temperature data is continuously recorded over time. The logging interval should be frequent enough to capture temperature fluctuations, typically every few minutes or less. 2. Historical Data Review Historical Trends: Review the historical temperature data of the separator bottom bearing. Look for any tr...

The ROI Principle for Value Statements

Image
When you're working for a company, it's crucial to understand and articulate the value of your work. This concept is summed up by what I call the 'Return on Investment (ROI) Principle': **“If you are being paid by a company to do work, you should be able to describe why that work is worth the pay.”** Your work is valuable. If you can pinpoint **why** it’s impactful, you can likely quantify it. Here’s how you can measure the value you bring to your job, with relatable examples to illustrate each point: 1. **Rupees Saved**: If you find a more cost-effective supplier for materials, you save the company money. 2. **Hours Reduced**: Automating a manual process can save your team countless hours each month. 3. **Work-flow Tasks Reduced**: Simplifying a complex workflow can reduce the number of steps and make the process more efficient. 4. **Processes or Controls Improved**: Implementing new quality control measures can reduce defects in production. 5. **Schedule Progress Made...

Position of Girth Gear on Rotary Kiln and Ball Mill is different. Why?

Image
The positioning of the girth gear on rotary kilns and ball mills is a strategic decision based on operational, maintenance, and design considerations. Here's a detailed explanation of why the girth gear is fitted at specific locations for rotary kilns and ball mills: Rotary Kiln Girth Gear at Kiln Inlet Side 1. Heat Considerations:    - Lower Temperature at Inlet: The inlet side of a rotary kiln is cooler compared to the outlet side where the clinker is discharged. Placing the girth gear at the cooler inlet side minimizes thermal stress and extends the life of the gear.    - Thermal Expansion: By positioning the gear away from the high temperatures at the outlet, thermal expansion and contraction are less pronounced, reducing the risk of gear misalignment and premature wear. 2. Maintenance and Accessibility:    - Easier Maintenance Access: The inlet side typically has more accessible maintenance areas compared to the outlet side, which may be enclosed by co...

WHAT IS TPM? | The Goals of TPM | Benefits of TPM

Image
WHAT IS TPM? Total Productive Maintenance (TPM) is a comprehensive approach to facility maintenance that aims to achieve perfect production and eliminate unplanned breakdowns. TPM maintains and improves equipment reliability, production output, and product quality. As per TPM everyone in a facility should participate in maintenance, rather than just the maintenance team. It engages all levels and functions in an organization to maximize the overall effectiveness of production equipment. TPM (Total Productive Maintenance) is a approach to equipment maintenance that strives to achieve perfect production. TPM is focused primarily on keeping machinery functioning optimally and minimizing equipment breakdowns and associated waste by making equipment more efficient, conducting preventative, corrective, and autonomous maintenance, mistake-proofing equipment, and effectively managing safety and environmental issues. The Goals of TPM: 1. No Breakdowns 2. No Small Stops or Slow Running ...

SHOCKING -> IT'S JUST CONTRADUCTORY TO THE MY EARLIER POST.

Eliminate your 1:1s Give feedback in front of people. Here’s why: Jensen Huang, CEO of NVIDIA, has 60 direct reports and zero 1:1s. He flattened all hierarchy, and in doing so, removed all games of telephone that can often dilute company mission and directives. Jensen has one meeting with all 60 direct reports. During that meeting he gives individual feedback…in front of the entire group. Sounds frightening to the average person and, when done poorly, could result in a toxic culture. Feedback in front of others, done well, can be both empowering and incredibly impactful. Jensen believes that giving feedback in a 1:1 session robs the other 59 reports of learning that same lesson. Similar principles are used in big coaching workshops like those Tony Robbins runs. Tony gives feedback to one person in front of the whole room of 3-4k people. Everyone gets to reflect on the lesson and apply learnings to their own experience. This principle is modeled in our Inflection retreats as well. At a ...
