AZO, Osterburken, Germany, has recently included an integral vibrating perforated sheet with its new Type ET…VS GA feeding hopper which was launched this spring at Powtech. The perforated sheet is designed to prevent packaging residue and other unwanted coarse material from entering production. The arrangement of the vibratory motors and associated vibration elements causes product to flow in a defined direction on the screen. Coarse particles that are larger than the screen mesh size are conveyed to the coarse material outlet, from where they are evacuated. The inclination and intensity of the vibratory motors can be varied to suit different products. The circular screens are available with a polyester/plastic fabric in mesh sizes of 2-5mm, or with special metal screens in a range of mesh sizes with no risk of wire rupture.

 

Throughput rates vary, depending on the product and mesh size. The following rates can be used for reference purposes: 4500kg/h wheat flour with a mesh size of 3mm; 1700kg/h powdered milk with a mesh size of 5mm. The hopper serves to feed powders and granulate into closed materials handling systems, such as a pneumatic conveying line. www.azo.com
