The material was change to liquid material after pass through a chute and then flow into the flow valve , which can prevent the flow control parts from forming columnar material 物料先通过一段小斜槽，使物料流态化，然后再进入流量阀，这样可避免在流量控制部分形成料柱。
Measures have been taken to save energy and reduce consumption . using chain - board elevator and air slides , reliability of the system is enhanced and conveying energy consumption is decreased 4充分考虑节能、降耗，生料入窑使用节能型的板链式提升机和空气输送斜槽，提高了系统的运行可靠性，降低了输送能耗。
The company has advanced technologies and the first - class equipment of examination and test of products . main products as below , raw elevator guide rails , container beam channel , forklift beam channel , mine using inclined beam channel , tire steel , ship - making bulb steel , track steel , equal angle bar , angle with unequal , silicon steel sheets , etc . and among them , bulb steel and track steel are the special kinds of products paid much attention by country 公司技术力量雄厚，检测设备一流，产品主要有：电梯导轨毛坯集装箱槽钢叉车槽钢矿用斜槽钢汽车轮辋钢船用球扁钢履带钢等边角钢不等边角钢矽钢片等，生产的“上三牌”电梯导轨毛坯技术含量高，是全国信得过产品，具有国际信誉。
A permanent magnet synchronous motor is selected so that the system could work excellently . multiform measures are taken to weakening the torque ripple , such as adopting stator - flume , choosing right ratio of magnet - width and slot - width , and programming properly . a permanent magnet synchronous motor cad software is worked out for predigesting the design of the motor 力矩脉动是衡量交流伺服系统性能优劣的重要指标，为达到理想的控制效果，系统采用正弦波驱动的稀土永磁同步电动机作为执行元件，电机本体的设计综合采用定子斜槽、将转子永磁体连续移位、合理选择永磁体宽度和齿槽宽度比等方法，基本消除了齿槽转矩；对于纹波转矩，系统采用软件的方式加以削弱和补偿。
