1. Project overview:
Pilot test address: Henan Zhengzhou Mining Machinery Co., Ltd.
Pilot unit: a research institute in Beijing
Product Name: Silicon Fertilizer
Pilot scale: 3 tons of silicon fertilizer production line per day
Scope of services: One-stop technology service from storage and transportation of raw materials, drying, milling, batching, mixing, granulation, calcination, cooling to storage and transportation of finished products, dust collection, electrical automation control and pilot data recording, etc.
2. Project description:
A research institute in Beijing is affiliated to the National Energy Group and was established in December 2009. It is a national innovation and entrepreneurship base for overseas high-level talents. This pilot project mainly focuses on the cleaning and recycling of fly ash.
3. Pilot test process:
The main raw material for the pilot test: fly ash.
Pilot product: high-efficiency citric acid-soluble fertilizer with effective silicon content ≧ 30%.
Pilot test process: raw material drying → grinding → batching → granulation → screening → calcination → cooling → screening → packaging.
