该机是本厂用于自行研制的最新型磨粉机，其特点如下：1、与同类磨粉机相比，在同功率的情况下产量有较大提高（增产20%-50%）。节约能耗2、增加了集尘装置，有效地降低了粉尘污染。3、主风机出料降低了操作工人的劳动强度。4、主机门盖可开，便于检修和刀具的更换。5、采用风水双冷，较好的降低了机体内的工作温度，所研制的料不易变性，同时也有利于热敏性塑料的磨制，可对部分PE，ABS进行磨制。 It is the latest grinder developed by our factory with features as follows1.Compared with similar grinders ,its output is greatly improved (increase by 20-50%)under the same power .It is energy-saving.2.The dust collector is added to effectively reduce dust pollution.3.The discharging of the air shutter reduces labor strength of operating workers.4.The door cover of the main machine can be opened for convenience of maintenance and replacement of knives.5.Wind and water cooling is adopted to decrease the working temperature inside the machine body ,the grinded material uneasy for transformation and be good for grinding of heat-susceptible plastics and that part of PE and ABS can be grinded.  工作原理 1、该机工作部分为刀盘。高速粒子在撞击齿板后部分被粉碎，经吸风抽出，而较大粒子则继续撞击，粉碎后被抽出。这样减少了刀盘负荷，提高磨粉效率，又能使粉料得到均匀冷却。2、温度低是该机的主要优点。按热功当量：每小时作功后转换为860千卡热量。本机为外抽风。风量达50m/KW由进、出口风温差，带走大部分热量。少部分热量由水冷却解决。要求冷水的进口温度不大于25℃，出口水温度不大于45℃，夏天适当增加冷却水流，以降低温度。 Working principles1.The working part of this machine is cutter disc .High speed particles are grinded after impacting gears and drawn out by absorption of air while large particles remain being impacted and are drawn out after being grinded,which reduces load of the cutter disc,improves power grinding efficiency and enables the powder materials be evenly cooled.2.Low temperature is the main advantage of this machine .In heat power:The power will be converted into 860kcals heat after the operation of each hour.This machine is external extraction fan .The wind amount reches 50m/kw and the wind temperature difference at inlet and outlet brings away most heat while little heat is handled by water cooling .The temperature at inlet of cool water is required not to exceed 25℃ and the temperature of water at outlet shall not exceed 45℃ .Cooling water flow can be appropriately added in summer to reduce temperature.  主要技术参考Main Technical  Parameter刀盘数：1只，外径：483mm±1 mm赤板：1付12片（优质合金刚，硬度50°-58°）刀片：24片（优质和金刚，硬度52-55）主电机转速：2950r/min主电机功率：30KW。配用三角带： B型，2007mm引风机：型号9-19，4#，配用电动机3KW关风机：型号ZGF，配用电动机0.75KW产量：PVC20目300kg/h外型尺寸：整套机器（长*宽*高）5900*1450*2900整机重量：1200kg 用途： 本厂吸收国内外先进技术研制开发的系列磨粉机。用于硬度低到中等的PVC塑料，高密度PE，或其它塑料经过试磨成功的。经塑料制品专业工厂实践操作证明，磨制粉料在加工回访中加入20%-30%碳酸钙，其制品的化学物理性能保持全新的各项指标不变而且产量可以达到300kg，因此，此设备是塑料制品厂降本节支，解决废品积累的最佳设备。 UsagesThis factory absorbs both domestic and abroad advanced technology to research and develop series of grinders.The PVC plastic for low to medium hardness,high density PE or other plastics succeed in trial grinding.It is evidenced by practices and operation of plastic manufacturing factories that the chemical and physical properties of the products can keep updated indexes unchanged and the output can be increased to 300kg if 20-30% calcium carbonate can be added in grinded materials during processing ,so this equipment is the optimal device of the plastic manufacturing factories to reduce this cost and solve waste accumulation.
