However, due to the light texture and alkaline nature of shell powder, it is very dusty when applied in coastal sandstorm areas. Prolonged contact with shell powder during application may cause burns to the skin, and local concentrati...

Abstract

The inventive technique process of grainy calcium material for preventing and treating peanut blight primarily includes: adopting the shell powder and weathered coal as raw materials, machining into peanut blight prevention material through agglomeration granulation. The invention has innovative and reasonable design, which not only has simple process, easy implementing, but also has low cost of raw materials, product application convenience, remarkable peanut blight prevention effect, and capability of promoting high-efficient production pf peanut. In particular, the invention applies coastal oyster shell wastes for machining calcium materials for preventing and treating peanut blight, which not only reduces environmental pollution, but also promotes recycling of resources, has very significant economic, social and ecological benefits and greater promotional value.

Example Embodiment

[0015] Example 1

[0016] Weigh 85kg of 80-mesh shell powder and 15kg of 80-mesh weathered coal, and mix them well.

[0017] First, transfer 50kg of the mixture to a disc granulator for granulation. The speed of the granulator is controlled at 30-45r/min, and water is sprayed intermittently. With the remaining material, the nuclei gradually grow up, and finally reach the desired particle (between 1.0-3.5mm); the control time of the granulation process is 15-25min. The granulated granular materials are directly sun-dried or transported to a dryer at 80-100°C for drying, so that the moisture content is not higher than 2.5%. Then the dried material is sieved through the screen, and finally the particle size of the finished product is controlled between 1.0-3.5mm, and the finished product rate can generally reach 80-85%. The unqualified products are crushed by the crusher and then re-granulated.

Example Embodiment

[0018] Example 2

[0019] Weigh 80kg of 80-mesh shell powder and 20kg of 80-mesh weathered coal, and mix the two well.

[0020] First, 40kg of the mixed material was transported to the disc granulator for granulation. The speed of the granulator was controlled at 30-45r/min, and water was sprayed intermittently. The remaining material makes the ball core grow gradually, and finally reaches the desired particle (between 1.0-3.5mm). The granulation process control time is 15-25min. The granulated granular materials are directly sun-dried or transported to a dryer at 80-100°C for drying, so that the moisture content is not higher than 2.5%. Then the dried material is sieved through the screen, and finally the particle size of the finished product is controlled between 1.0-3.5mm, and the finished product rate can generally reach 80-85%. The unqualified products are crushed by the crusher and then re-granulated.

Example Embodiment

[0021] Example 3

[0022] Weigh 82kg of 80-mesh shell powder and 18kg of 80-mesh weathered coal, and mix them well.

[0023] First, 60kg of the mixed material was transported to the disc granulator for granulation. The speed of the granulator was controlled at 30-45r/min, and water was sprayed intermittently. The remaining material makes the ball core grow gradually, and finally reaches the desired particle (between 1.0-3.5mm). The granulation process control time is 15-25min. The granulated granular materials are directly sun-dried or transported to a dryer at 80-100°C for drying, so that the moisture content is not higher than 2.5%. Then the dried material is sieved through the screen, and finally the particle size of the finished product is controlled between 1.0-3.5mm, and the finished product rate can generally reach 80-85%. The unqualified products are crushed by the crusher and then re-granulated.

[0024] The invention is innovative and reasonable in design, not only simple in procedure and convenient in implementation, but also in low cost of raw materials and convenient in product application, can effectively prevent peanut hollowing, and is favorable for continuous and efficient production of peanut. In particular, the application of coastal oyster shell wastes into peanut seedling treatment materials not only reduces environmental pollution, but also drives the recycling of resources. Its economic, social and ecological benefits are very significant, so it has great application and promotion value.
