● Weightless continuous formula metering platform scale is designed to meet the requirements of continuous production process, automatically and continuously weighs various raw materials according to proportion of ingredients and feeds them into continuous mixer or biaxial extruder, so as to serve the function of continuous discharge of the mixer of extruder.
● Since continuous mixers or extruders have been widely used in different industries such as plastic products, rubber products and packaging films, the types of raw materials and formula ratios are different due to different machine capabilities. Depending on customer requirements, some use one sort of material while some use many sorts of materials, and some use the same feed inlet while some use different feed inlets. 
● Such weightless continuous formula metering platform scale reduces abnormality of intermediate variables and abnormality of manual feed by combining automatic feed of raw materials with weight-losing continuous formula and platform scale. 
● Body: The body is an enclosed house that fixes suction feeder, platform scale and control cabinet.
● Suction feeder: Raw materials are suctioned from the storage tank by way of vacuum intake and temporarily stored in the suction feeder. Different number of suction feeders is furnished according to different settings of machine. 
● Weightless continuous platform scale: it is composed of quantitative discharge machine integrating middle vessel and agitating auger as well as load cell.
● Control cabinet: The control cabinet is an automatic control box that combines PLC such as suction, feed, metering and other kinds of control elements.
● Man-machine control box: The man-machine control box is the kind of control box that sets, displays and controls all operating control procedures, and is installed in nearby operation room according to the needs of operation. 
● Raw material storage tank: Raw material storage tanks of 1M3 and 2M3 are designed according to usage amount and package. Raw material storage tank is furnished with several suction tubes that are connected to the suction feeders of the lines, and agitator is furnished below the storage tank to prevent the appearance of bridging. 
● Windmill: One or more suction feeders can be driven by one windmill according to the material usage amount of the platform scale.
