华之强有机肥设备液压对辊造粒机用途与特点：
HD系列液压对辊造粒机是采用干法辊压工艺技术，主要靠压力进料加压方式，使物料强制通过两个相对旋转辊轮间隙，强制压缩成片块状，在辊压过程中，物料的实际密度能增大1.5~3倍，对含水量≤5%的粉状物料进行压缩成片或块状，从而达到颗粒强度要求。再经破碎整形，筛分工艺，使片块状物料变成使用要求的颗粒状物料。主要适用于化肥原料（硫酸钾，氯化钾，钾肥，碳酸钙，硝酸钾，磷酸铵等）;化工原料（抗氧剂，氧化锌，金属粉末，植物燃料等）以及环保材料的压缩造粒过程。
Hydraulic Roller Granulator Use and Features:
HD series hydraulic press granulator adopts dry roller press technology, which HD series hydraulic er-roller granulator adopts dry rolling technology, mainly relying on pressure feeding method, force material through two opposing rotating roller gaps and compress into pieces. In the process of rolling press, the actual density of the material can be increased by 1.5~3 times, and the powder material with water content less than 5% is compressed into pieces or Lump, thereby achieving granule strength requirements. After crushing and shaping, the lump material is turned into granular that meets the requirements of application. It is mainly suitable for chemical fertilizer materials (potassium sulfate, potassium chloride, potash fertilizer, calcium carbonate, potassium nitrate, ammonium phosphate, etc.）;Chemical raw materials (antioxidant, Zinc Oxide, metal powder, plant fuel, etc.), and the compression granulation process of environmental materials.
