Embodiment

[0023] as attached figure 1 The pulp grinding disc made of high-chromium white iron shown in the figure can be used as a dynamic grinding disc of the grinding machine; the disc surface is an overall disc shape, and there are a plurality of single teeth evenly distributed on the inner side of the disc surface , there are two concentric annular teeth with different radii on the periphery of the disk.

[0024] The ring tooth is composed of a ring tooth root and a plurality of ring teeth, the ring tooth root is in the shape of a complete circle, the ring tooth root is connected to the disk surface, and a plurality of ring teeth are dispersedly connected to the ring tooth root.

[0025] as attached figure 2 , attached image 3 As shown, the shapes near the tooth heads of the single tooth and the ring tooth are both isosceles triangular pyramids, and the direction of the tooth shape is the tangent direction of the arc at its position, and they are all clockwise. The addendum ang...

Abstract

The invention discloses a pulp abrasive disc which can be made of high chromium white iron. According to the pulp abrasive disc, a plurality of single-teeth are distributed on the inner side of the surface of the abrasive disc, annular teeth are arranged on the periphery of the surface of the abrasive disc, each annular tooth is composed of an annular tooth root and an annular tooth body, annular tooth roots are composed by one or more complete circles or a plurality of arcs with the same radius, tooth profile directions of the single-teeth and the annular teeth are all clockwise, height of the single-teeth and the annular teeth is 12-16 mm, height of the annular tooth roots is 8-12 mm, and tooth tail width of the single-teeth or the annular teeth is 12-16 mm. The pulp abrasive disc is capable of increasing volume of an abrasive chamber, increasing the rubbing area of abrasive teeth, and improving grinding efficiency and grinding quality, and suitable for grinding of various pulp such as hardwood pulp, cork wood pulp and non-wood pulp.

Description

technical field [0001] The invention relates to a grinding sheet for a grinder, in particular to a grinding sheet suitable for pulp grinding. Background technique [0002] The work of the grinding machine is to rely on the relative movement (rotation) of the moving plate and the static plate to cut, squeeze and knead the material (such as wood pulp). Each grinding machine has a moving plate and a static plate, the moving plate is composed of the moving plate fixing seat and the moving grinding plate, and the static plate is composed of the static grinding plate fixing seat and the static grinding plate. The grinding disc (moving grinding disc, static grinding disc) is composed of a disc surface and a plurality of teeth distributed on the disc surface. Depending on the size of the grinding machine, the disk surface can be in the shape of a whole disc or a disc composed of several sector pieces; different tooth shapes and different tooth shape distributions will produce diffe...
