1,The introduction of the product:
ZH series automatic BB fertilizer production line is a new product indepently designed and produced by our company through investing the market demand,analyzing the market development situation,summarizing advanced experience,overcoming the disadvantages of development of other manufacturers and combining advanced technology with industrial stainless steel materials. 
Product advantages:Beautiful appearance,reasonable design,simple operation,accurate measurment.
Product features:high precision,fast speed,low engery consumption,small footprint.
Product configuration:raw material conveying systen,batching metering system,material mixing system,product packing system,high-performance control system.
The equipment overcomes the phenomenon of mixture chromatography or shunt caused by different proportion of raw materials and particle size,and improves batching accuracy.It solves the the impact of material characteristics, mechanical vibration, air pressure, voltage fluctuations, cold weather and other factors on the system, with high precision, fast speed, long service life and other characteristics, is a better choice for BB fertilizer (mixed fertilizer) manufacturers.
2,Main system features:
Batching system:single bag metering,the metering range is adjustable from 20 to 60 kg,the actuator adopts pneumatic drive,size two stages of feeding;This system adopts shockproof processing,multi-stage filtering technology,various materials can be measured indepently
oraccumulatively,with their own rough measurment,precision measurment and overshoot compensation,to ensure the measurement accuracy.According to different and  overshoot compensation, to ensure the measurement accuracy;According to different models, weighing scales are divided into single scale bucket, multi scale bucket, raw materials can be 3~8 kinds.
Material mixing system: use double spiral mixer, mix evenly, high production efficiency.Single bag mixing, mixing range of 20~60 kg adjustable, to overcome the large ingredients in the production process need to add more percentage content, and the shortcomings of material separation, saving costs.According to different models, there are single mixing cylinder and double mixing cylinder to choose from.
High performance control system: the nh-810 batching instrument adopted by the company has extraordinary batching control function, full Chinese display, user-friendly operation interface, intuitive and simple operation;It USES dual CPU hardware structure, all industrial-grade chips, SMT card technology and high speed 16bitA/D converter.The instrument adopts multiple filtering technology of power supply, input-output photoelectric isolation, resistor-capacitance filtering, transient voltage suppressor overvoltage protection technology, software digital filtering, various data verification measures, watchdog reset and other anti-interference measures, so that the instrument still has high weighing accuracy in the very complex industrial site.The whole system is fully automatic control, high-speed RS232/RS485 communication interface, can store 32 kinds of formula, can modify the formula according to requirements;With automatic zero tracking, coarse measurement and automatic compensation of drop, automatic measurement and modification of overshoot and fault alarm.
