The usage method of mineral powder binder typically involves the following key steps:
# Preparation
- Raw material selection: Ensure the quality and particle size of the mineral powder raw materials meet the requirements, usually with a particle size of less than 80% (below 3mm) and a moisture content of less than 8%.
# Proportioning and Mixing
- Proportioning: Determine the ratio based on the type of mineral powder and the performance of the binder, such as 1000KG of iron concentrate powder, 15-20KG of dry powder binder, and 50-80KG of curing water.
- Mixing method: Add the mineral powder and binder into the mixing equipment in proportion, stir thoroughly to ensure the binder is evenly distributed in the mineral powder.
# Water Addition and Stirring
- Water addition: Add an appropriate amount of water according to the material humidity, controlling the material humidity within a suitable range (usually forming a ball when held in hand).
- Stirring: Use a mixer to fully mix the material and water, ensuring the material is evenly moistened to form a mixture with a certain viscosity.
# Molding
- Briquetting or block pressing: Feed the evenly stirred material into a briquetting machine or block press for molding operations, ensuring appropriate molding pressure to obtain high-strength pellets or blocks.
# Drying
- Drying conditions: Place the molded pellets or blocks into a dryer and dry at an appropriate temperature (e.g., 150°C) for 2-3 hours, or allow them to air dry naturally.
# Quality Inspection
- Strength testing: Conduct strength tests on the dried pellets to ensure they meet the usage requirements.
- Appearance inspection: Check the appearance of the pellets to ensure they have a smooth surface without cracks.
It should be noted that the specific usage methods may vary for different binders, and adjustments should be made based on the technical guidance provided by the binder manufacturer and actual conditions.
