一、用途及特点：

跳筛用于纸浆的粗选、净化。通过频率振动将粗浆中的骨节，薄膜及其它粗大杂质筛出。良浆经过筛板进入下道工序，振框筛具有结构简单、维修简便、生产费用低、生产效率高等优点，是造纸厂家理想的浆料筛选净化设备。本设备分为高频振框式、低频自洗式、高频自振式三种。

Skip screening is used for rough selection and purification of pulp. The joint, the thin film and other coarse impurities in coarse pulp are screened out through frequency vibration. The good pulp enters the next process through the sieve plate. The vibrating frame sieve has the advantages of simple structure, simple maintenance, low production cost and high production efficiency. It is an ideal pulp screening and purification equipment for paper mills. This equipment is divided into three types: high frequency vibration frame type, low frequency self washing type and high frequency self vibration type.
