Problems solved by technology

Disadvantages are the slip due to the belt drive, which makes it impossible to achieve a defined meshing angle of the two crushing rollers with respect to each other and, moreover, does not ensure a continuous particle size due to the increase in the crushing gap in the case of overload
Furthermore, belt drives require high safety expenditure due to the large pulleys, must be protected against flying mineral fragments and are also expensive to maintain

Embodiment Construction

[0021] figure 1 A roller crusher according to the invention is shown with two drive chains. The roller crusher has two crushing rollers 3 which are arranged in a housing 2 . Arranged on the side of the housing 2 perpendicular to the crushing roller 3 are two transmissions 4 , the output shafts of which are arranged coaxially with the crushing roller 3 and are connected to the crushing roller.

[0022] The drive shaft is arranged on the same side of the transmission 4 as the output shaft, but further outside, so that the axis of the shaft is shown next to the roller crusher housing 2 . Furthermore, next to the housing 2 two motors 6 are arranged as far as possible axially parallel to the crushing roller 3 , which are each driven via a cardan shaft 8 of one of the transmissions 4 . A hydraulic clutch 7 is also connected between the cardan shaft 8 and the motor 6 respectively. The hydraulic clutch significantly improves the start-up behavior in the case of overfilled roll crus...

Abstract

The invention relates to a drive train for a roller crusher having at least one transmission and a motor, wherein the motor drives the drive shaft of the transmission directly and the output shaft of the transmission directly drives the roller crusher. Driven directly, in this context, means that the force transmission occurs without slippage, meaning not via a belt drive or something similar. According to the invention, the transmission is designed such that the drive and output shafts are on the same side of the transmission and thus the motor and roller crusher are also arranged on the same side of the transmission. The drive train advantageously thus makes a hairpin bend, by means of which the total length of the crusher can be significantly reduced. According to the invention, an articulated shaft is particularly preferably arranged between the motor and the transmission or between the transmission and the roller crusher. The motor or the crusher can thus be advantageously arranged offset to the transmission, and the crusher designed to be even smaller. The effort required to align the motor shaft or the shaft of the crusher roller with the transmission shaft is furthermore advantageously eliminated.

Description

technical field [0001] The invention relates to a drive chain for a roller crusher and to a roller crusher with a drive chain of this type, wherein the crusher can be used in mining as a pulverizer for minerals. Background technique [0002] Different types of roll crushers belonging to the group of screens are known. They differ between the number of rollers and the type of drive for the rollers. Twin roll crushers with two crushing rolls are often used. Twin roll crushers have a single-sided drive (ie only one roll is driven) or a double-sided drive. By synchronizing the two breaker shafts, it is possible to drive both breaker shafts with a single-sided drive. In the drive chain, there is usually a transmission mechanism between the motor and the crusher. Such a breaker is eg disclosed in WO2010 / 032037A. In addition to the large installation space required for such a breaker, the high complexity for aligning the drive chain is also disadvantageous. [0003] Direct dr...
