Steel ball is a commonly used grinding medium with the following characteristics:
1. High hardness: Grinding tool steel ball is usually made of high carbon chromium steel material, high hardness, can effectively grind hard materials.
2. Strong wear resistance: Due to the use of high hardness material, grinding tool steel ball has good wear resistance, can be used for a long time and is not easy to wear.
3. Good compression resistance: After special treatment, the steel ball of the grinding tool has high compression resistance, can withstand greater pressure, and is not easy to deformation or fracture.
4. Good grinding effect: The steel ball of the grinding tool has high grinding efficiency and grinding accuracy, which can quickly and evenly grind the surface of the object to achieve the required smoothness or accuracy.
5. Widely used: Grinding tool steel ball can be used for metal materials, ceramic materials, glass and other materials grinding processing, widely used in machining, electronic manufacturing, chemical industry and other fields.
It should be noted that the appropriate size and material need to be selected according to the specific situation during the use of the grinding tool steel ball to ensure the grinding effect and service life. In addition, pay attention to safety precautions during use to avoid damage to personnel and equipment

The so-called fertilizer application is based on soil conditions, crop growth needs, nutrient supply, two or more fertilizers with different properties and different functions, such as nitrogen, phosphorus, potassium fertilizer, or quick-acting fertilizer and late-acting fertilizer, or Organic fertilizer is mixed with inorganic fertilizer, micro-fertilizer and growth hormone.
Main principles of mixed use
Mixing between fertilizers, including micro-fertilizers, micro-fertilizers and common fertilizers, must follow the following principles: (1) Mixed application should be highly targeted and must be suitable for crop nutrient and soil fertility conditions; (2) After mixing, it is necessary to achieve the effect of mutual benefit, so that the physical properties of the fertilizer can be improved; (3) It is beneficial to enhance each other's effectiveness, and the fertilizer efficiency of any one of the fertilizers cannot be reduced, and the "one application is effective" is realized. Expectations.
(1) Zinc fertilizer should not be mixed with alkaline fertilizers such as ammonia. It is best not to mix with superphosphate phosphate soluble phosphate to avoid zinc phosphate precipitation and reduce fertilizer efficiency. (2) Mixed application of trace element fertilizers When the concentration and dosage should not exceed the specified amount, otherwise the seeds after soaking and seed dressing will not emerge, and the spraying of the leaves will cause damage to the seedlings; the trace element fertilizer should not be mixed with the grass ash; (4) various micro When the fertilizer is mixed with the soil and fertilizer, it should be diluted gradually, fully and evenly. It is best to mix it with a small amount of fine soil and then mix it with the soil; (5) Spray the micro-fertilizer with water, or When mixed with manure, it should be dissolved with a small amount of water, then added to clean water, manure water and fully stirred before application, so as not to cause burning and burning.
