According to their function, vibration filters divide into industrial using and laboratory using. We have many types of filters, such as standard type, flanged, sluice gate type, supersonic type, double-motor type, All closed with vibration hopper type for industrial using and 200 Particle analyzing instrument for laboratory. Our��400mm?#1092;2500mm series sifters, which are made of high quality stainless steal, install up to four layers of sifters. The inside electromotor can vibrate steadily and generate great vibration strength. Moreover, the net frames are flexible and easy to stretch completely and can be replaced in a very short period of time so that the efficiency has dramatically arisen. Our ��400mm-��1000mm series vibration with trays have reached the world quality standard. They are proved to have long life-span and high filtration efficiency. They are featured as reliable steadiness, ease in operation and repair, low noise and consumption, high productivity and accuracy, smooth net holes and tight seal. These machines have been used in sieving of solid construction or mining materials or liquid materials. They are widely used in food, pharmaceutical, chemical, metallurgical, construction, glass, ceramic and paper-making industry. Regards, Ms. Ginger Lee Zhengzhou Sinco Machine Co., Ltd
