On this page, you can find preventive maintenance principles, maintenance schedules, checklists, and step-by-step maintenance procedures for various equipment in mill and grain processing systems. These guides have been prepared with Tanış A.Ş.’s over 60 years of industry experience and technical expertise.

Creating a Preventive Maintenance Program

An effective preventive maintenance program reduces downtime, extends equipment life, and lowers operating costs. To create a successful maintenance program:

• Create Equipment Inventory: List all equipment, record technical specifications, model numbers, and manufacturer information.
• Perform Criticality Analysis: Classify equipment according to its importance in the production process, failure risk, and replaceability.
• Determine Maintenance Periods: Create daily, weekly, monthly, and annual maintenance calendars based on manufacturer recommendations, operating conditions, and equipment age.
• Assign Tasks: Determine maintenance personnel’s areas of responsibility and competencies.
• Plan Resources: Determine time, personnel, spare parts, and tool-equipment needs required for maintenance.
• Establish Monitoring and Improvement Mechanism: Determine KPIs to measure maintenance effectiveness and conduct regular evaluations.

A systematic documentation structure is essential for recording, analyzing, and improving maintenance activities:

• Equipment Cards: Records containing technical information, maintenance history, and spare parts information for each equipment
• Maintenance Schedules: Calendars showing planned maintenance activities
• Maintenance Instructions: Step-by-step maintenance procedures and checklists
• Failure Records: Records containing failure types, causes, and solutions
• Performance Reports: Metrics and analyses showing maintenance effectiveness

Roll System Maintenance Guides

Roll systems are the most critical equipment in mill facilities and require regular maintenance:

Daily Maintenance Operations:

• Check the operating temperature of roll motors
• Check the cleanliness and adjustment of roll scraper blades
• Check for abnormal sounds and vibrations
• Check product flow and whether there is accumulation on the rolls

Weekly Maintenance Operations:

• Check belt tension and adjust if necessary
• Check roll lubrication points and grease them
• Check the condition of roll scraper blades
• Clean roll feeding mechanisms

Monthly Maintenance Operations:

• Check parallel adjustment of roll cylinders
• Check the working condition of roll pressure mechanisms
• Check the condition of motor bearings
• Check belt wear condition

6-Monthly / Annual Maintenance Operations:

• Check roll cylinder wear condition in detail
• Check roll bearings and replace if necessary
• Check motor electrical connections and insulation
• Check drive system in detail and replace necessary parts
