Embodiment Construction

[0073] First refer to the following figure 1 with figure 2 , the principle of the crushing device meeting the requirements of the first aspect of the present invention will be described. The pulverizing device includes a feed port 110 through which liquid containing solids is fed. The liquid containing solids meets an annular orifice plate 120 with a plurality of openings through which the solids and liquid can pass. The orifice plate is fixedly mounted on a discharge casing 130, and the fluid containing solids after the solids contained therein are crushed enters the casing, and then flows out of the discharge casing in a radial direction through a discharge port. .

[0074] On the side of the perforated plate 120 facing the inflow opening is arranged a knife holder 140 with a total of four knives 141 a - d arranged thereon. The cutting edges of the knives 141 a - d are located on the side of the orifice plate 120 facing the feeding port. Each of the knives 141 a - d ex...

Abstract

The invention relates to a comminution device, in particular to a comminution device comprising an adjusting mechanism, said adjusting mechanism including a hydraulic cylinder (165, 167) which is coupled between the first and the second cutting element and is in hydraulic communication with a closed hydraulic and pneumatic volume (220, 230), which is filled with a hydraulic fluid in a first part (220a) and with air in a second part (220b), and the wall of which is at least partially transparent so that the hydraulic fluid level can be read from a scale (222) which displays a wear condition of the first and second cutting element. The invention also relates to a comminution device in which lubricant-filled cavity (380) is formed between a first area (32; 453) and a second area (342; 463), the volume of said cavity being reduced by an adjusting movement of the second cutting element and which is in fluidic communication with the positive engagement connection in order to supply lubricant to the positive engagement connection.

Description

technical field [0001] The present invention relates to a comminuting device comprising a first cutting element having at least one first cutting edge, a second cutting element movable relative to the first cutting element on a first movement path and comprising at least one second cutting edge . Here, the second cutting element rests against the first cutting element in such a way that a relative movement of the second cutting element along the first path of motion causes a shearing effect between the at least one first cutting edge and the at least one second cutting edge . The pulverizing device also includes an adjustment mechanism that adjusts the second blade relative to the first blade on the second path of motion in such a way that when the first and / or second cutting element is driven by the first cutting element along the When worn by the relative movement of the first moving track, the first cutting element is guided to always be in close contact with the second c...
