Identification : VRPM,
Type of construction : motor
Characteristics and application :
Roll flow control gate with motor drive (further only VRPM) serves for material flow regulating and closing in technological lines. It is determined for material temperature up to 120°C. Flow quantity is regulated with turning of inside roll, which is operated by means of a geared motor. The equipment is designed for milled powdered materials and it is dustproof.
Dimensions and parameters :
Type range of roll flow control gates is designed in 8 basic sizes
Description of construction :

Drive of VRPM is done by means of geared motor with leverage, which is bolted on the body.
Used material :
Construction – casing (body) of VRPM is welded and is made from a normal steel St-37 (class 11 acc. CZ-Standard ČSN), the transported product touching parts are made from steel St-52 (class 11 acc. CZ-Standard ČSN). Inside roll is made from steel St-52 and it is fixed with shaft into self-lubricating sleeves on outside covers.
