摘要:
A roller mill for grinding particulate material, such as cement raw materials, cement clinker and similar materials has a rotatable grinding table with a substantially vertical centerline and a number of rollers being configured for interactive operation with the grinding table and turning about separate roller shafts which are fixed to a rotatable center shaft with a substantially vertical centerline. The center shaft and the grinding table are fixed one to the rotor and the other to the stator of the same motor, which may have the capability of rotating both the grinding table and the center shaft.

Described is a rolling bearing (1) for a rocker arm, said rolling bearing comprising an at least partly circular outer part (2), an at least partly circular inner part (3) and a number of rolling elements (5) which are fitted between the outer part (2) and the inner part (3). The rolling bearing is peculiar in that at least one of the rolling elements (5) comprises two opposite, curved side faces (6, 7), which viewed in at least one cross-sectional constitutes arc lengths of the same imaginary circle (10), and which constitutes contact faces for the outer and the inner circular part (2, 3) respectively, and at least one side surface (8, 9), which lies within the mentioned imaginary circle (10).It is hereby obtained that the number of rolling elements in the bearing can be increased, thereby reducing the load on each single rolling element subject to the same total load rate, thereby increasing the total load bearing capacity of the bearing. This is due to the fact that at least a part of the roller face of the traditional circular rollers which do not get into contact with the outer or inner part of the bearing through small reciprocating angular rotations is omitted thereby significantly reducing the space taken up by each of the rolling elements in the circumferential direction of the bearing.

A glass crushing machine and glass crushing system comprise a cylinder crushing chamber 2; a powder and particle collecting chamber 4 formed to be cylindrical and disposed downward of the crushing chamber 2; a funnel-like crushed substance collecting portion 5 disposed at the powder and particle collecting chamber 4; a porous bottom plate 7, detachably and attachably disposed between the crushing chamber 2 and the powder and particle collecting chamber 5, having a number of pores and divided into a plurality of segments; a drive shaft 8 disposed at a roughly middle part of the crushing chamber 2; a roller rotating shaft 10 connected to the drive shaft 8 via a connection member; crushing rollers 11 rotatably fitted to the roller rotating shaft 10 and having crushing elements 12 consisting of rows of square columns formed in duplex on the outer circumferential surface. The glass crushing machine has excellent durability, and can efficiently crush a large quantity of glass products into any desired particle size without leaving crushed pieces of glass in the crushing chamber and without damaging the drive portion. Furthermore, the glass crusher can be adapted to be mobile.
