1. Application time. Farmhouse fertilizers are slow to be effective and should be applied early. Generally, they are applied once before sowing. However, the amount of chemical fertilizer is small, and the effect is quick. Generally, it should be applied about 7 days before the peak of nutrient absorption.
2. Application method. Farmyard manure should be combined with deep tillage into the soil tillage layer, or combined with ridges to buckle into the bottom of the ridge. Nitrogen fertilizer with farmyard manure, 30% as base fertilizer, 70% as top dressing, phosphate fertilizer and potash fertilizer as base fertilizer applied once.
3. The amount of application. Fertilizer and farmyard manure application, the amount can be different according to crop and soil fertility, such as planting corn on infertile ground, 4 cubic meters of farmyard manure per fertilizer, 24kg of urea, 13kg of phosphate fertilizer, or 3 15% of compound fertilizer 13kg; medium fertility soil can be applied to farmer's fertilizer 3 cubic meters, urea 20kg, or 3 15% of compound fertilizer 12kg; high-fertility soil can apply farmer's fertilizer 2.5 cubic meters, urea 15kg. Urea is better used in top dressing, and compound fertilizer is better in base fertilizer.
CBN is a man-made Superabrasive that outperforms Diamond when used for Ferrous grinding operations.
CBN derives its name from its chemical makeup, of the cubic form of boron nitride (CBN). It has a very desirable characteristic that is sought after when working with difficult to grind (DTG) materials.
Due to its high thermal stability and chemical resistance, the CBN grinding wheel is most suitable for grinding hard ferrous materials, hardened steel, bearing steel, nickel based alloys. machining ferrous materials.
CBN Grinding Wheels are used to sharpen, cut, or remove metal from hard surfaces. Use these wheels when you need a good consistent finish.
Most notably CBN wheels are used to cut HSS metals, like wood tools, blades, bits, and cutters. This type of steel is better than the older high-carbon steel because it can withstand higher temperatures. When you`re tools become dull over time from use, a CBN wheel will bring them back to its sharp use.
Kemei produce CBN(cubic boron nitride)grinding wheels, which can be resin bonded CBN wheel, metal bonded CBN wheels and electroplated Diamond Grinding Wheels. For same steel parts, you can choose all three types CBN wheels, but there still some difference, if you need more information and the best solutions ,please contact us.
