Common issue: Snowman formation.  Root cause in Case#1. Static Grate fans RPM were less.  Why: Because of wrong O/load setting, CCR couldn't increase the speed.  Action taken: O/load setting reset and problem solved [2018, 1350TPD plant]. Root cause in Case#2. Frequent temperature spike in kiln + preheater due to uneven coal dosing.  Why: Uncontrolled coal firing due to coal flushing through Feeding screw. Action taken: Barrel of screw was modified with a simple solution. Temperature controlled and problem solved [2022, 2300TPD plant].  Root cause in Case#3. Air Blaster purging pressure was less. They were not being fully charged.   Why: No header for air blasters. 1/2" line from main pipe line and tapping of the same size for 12 nos. of air-blasters (sounds funny but such things happen).  Action taken: Supply line upgraded. Header provided.  No snowman after that [June-2024, 5500TPD plant].

अगर आपने फिर से मुझे फोन किया है तो आपका नाम देखकर ही मुझे पता चल जाएगा कि आप मेरे साथ किस तरह से कनेक्ट हो, आपका नाम क्या है, कंपनी का नाम क्या है और कहां से है, और हमारी पहले मुलाकात या बात कब और कैसे हुई थी। और हां इसके लिए कोई बड़ा टूल नहीं है। आपका नाम मैंने जिस प्रीफिक्स और सफिक्स  के साथ से सेव किया है उसी से मुझे यह सब पता चलता है। स्मार्टफोन तो बाद में आया लेकिन जब से एक्सेल शीट उसे करना शुरू किया तब से मेरा कांटेक्ट मैनेजमेंट इसी तरह शुरू हो गया था।  इसका फायदा यह हुआ के जैसे ही गूगल कांटेक्ट जैसा जबरदस्त टूल मिला तब सारे कांटेक्ट उसके ऊपर ट्रांसफर [इम्पोर्ट] हो गए।  नए कांटेक्ट को सेव करने में टाइम नहीं लगता लेकिन हम इसको बहुत छोटा काम समझ कर पोस्टपोन कर देते हैं और फिर वह कभी नहीं होता।  हमें तो कांटेक्ट सेव करना है बस। बाकी काम तो गूगल ही कर देता है जैसे सिंक्रोनाइज़ करना, डुप्लीकेट कॉन्टेक्ट्स को मर्ज करने के लिए सजेस्ट करना, जो कीवर्ड दो उसके हिसाब से रिजल्ट निकल देना, वौइस्-कमांड से कॉल लगा देना।  कांटेक्ट मैनेजर (स्प्रेडशीट) के अलग अलग सेल से डेट...

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...

These notes are for my engineers who are working with me. If you read it, it may help you but there is a science behind it with actual work and practical exercises.

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...

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? 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 ...
