Fill-in-the-blank questions: In the PVC production process, the function of the drying vibrating screen is _________________________; the specifications of the vibrating screen mesh are _________________________. Answer: Separate the coarse particles from the PVC resin ； 25–30 mesh or 40 mesh
The function of a vibrating dryer screen is to _____process solid particles____; the dimensions of this vibrating screen are ____585*1165mm_________.
1. It operates by utilizing the reciprocating helical vibration generated by vibrator excitation. The upper rotating weight of the vibrator causes the sieve surface to undergo planar rotational vibration, while the lower rotating weight induces conical rotational vibration on the sieve surface; the combined effect of these two results in complex rotational vibration of the sieve surface. Its vibration trajectory is a complex spatial curve. 2. Vibration screening equipment can be classified by weight and application as: mining vibration screens, lightweight precision vibration screens, and experimental vibration screens
The function of a vibrating dryer screen is _sorting, removing liquids, and eliminating impurities_. The types of vibrating screens include _air-sealed type, direct-drain type, jet-type, water-jet type, rotating-brush type, mobile-wheel type, etc._.
Separate particles of different sizes, improve drying efficiency, use fixed screens, etc
It can quickly separate large or small slag particles with a low percentage content. A single vibrating screen can be equipped with up to 4 layers of screens, enabling the continuous separation of 2–5 particle sizes while allowing for control over a narrow particle size range
Its functions are screening, impurity removal, and filtering. Vibrating screen mesh size: 400–600 mesh
In the PVC production process, the function of the drying vibration sieve is to _______select out the particles__________________. The mesh size of the vibration sieve screen is ________8 mesh_________________.
