bivitec Difficult-to-screen bulk materials and highest levels of separation we process the future Processing Technology

TASK 2 In processing technology, it is increasingly a question of classifying raw materials and intermediate products. This places considerable problems on such conventional screening machines as circular vibratory screens and linear vibratory screens. Three main reasons are responsible for this: The high material humidity in connection with clay, mud or other impurities causes a build-up on the screen surface Fingery as well as bladed material leads to the development of sticking grain Fibrous, matted substances entangle the screen webs Result: In all the three cases, no screening can take place...

SOLUTION In order to ensure the screening function, the acceleration values to be made to act on the screening material that is difficult to screen are much higher than usually. For optimally fulfilling this task, Binder+Co has developed a solution that is both simple and efficient: BIVITEC screening machines with a dual vibration principle from a single drive. The development of the BIVITEC screening machines was based upon the conventional circular vibratory screen. This screen is the body describing the fundamental mode even today. The linear vibratory screen represents an advance as a basic...

TECHNOLOGY The dual vibration principle of BIVITEC screening machines results from a fundamental oscillation and an overlaid vibration. The fundamental oscillation describes a circular or linear motion, which is introduced by a circular or linear vibratory screen. The overlaid vibration describes an elliptic motion and is started by the fundamental oscillation. The Bearings The screening machine is bedded on hollow springs made of rubber, because the following advantages won‘t be provided by helical springs: Hollow springs made of rubber cause little noise have optimal inlet and outlet properties...

quality in use Practical BIVITEC screening machines are designed for screen cuts of 0.2 – 50 mm. The fact that the screen mats are fixed without screws guarantees a gentle screening as well as a fast change of the screen mats and prevents caking. For changing a screening area of 10 m2, about one working hour is required. Efficient The descending gradients of the screening machine that are selected are low in order to ensure that particles frequently hit the screen mats and therefore an optimal screening performance can be achieved. The lateral OX-HORN designed seal prevents outsize rejection...
