Embodiment Construction

[0025] FIG. 1 shows a grinding machine 1 with two rows of rollers, each row being two rollers 2 . All rolls 2 are equipped with tearing elements 3 . The tearing elements 3 are formed as rods, which have the same thickness along their entire length and are fixed perpendicularly to the outer surface 4 of the roller 2 . The rollers 2 are mounted in such a way that the tearing element 3 almost reaches the outer surface 4 of the adjacent roller. The inside of the walls of the mill 1 is also provided with tearing elements 5 at the level of the first and second row of rollers, so that the tearing elements 3 of the rollers also interfere with these tearing elements 5 .

[0026] Above the first row of rollers 2 there is installed a vibrating device, hereinafter referred to as a vibrator 6 . The purpose of this is to prevent the material added to the grinder 1 from becoming lumpy and thus from falling onto the roller 2 but hanging over it as a bridge. The vibrator 6 vibrates intermit...

Abstract

An apparatus for drying materials such as fertilizers, mud, etc., comprising a grinding section and a drying section comprising at least one conveyor belt (10) and an air heater (16). A closed air circulation system is provided above the conveyor belt, which directs air countercurrently to the material on the conveyor belt. The temperature of the air heated in the heater (16) and the time for drying the material are adjusted so that the dried material does not contain bacteria and weeds.

Description

technical field [0001] The invention relates to a device for drying materials, such as fertilizers and slurry, according to the preamble of claim 1 . This device is especially suitable for drying chicken manure. Background technique [0002] Currently, the Norwegian Authority requires that if a farmer has a certain number of livestock, he must have a correspondingly large area for spreading manure. For example, in order to keep 5000 poultry, he would have to have an area of ​​about 19 acres (300 Norwegian ml). Thus, at times, the area available for spreading manure will limit the number of livestock a farmer can keep, thereby limiting the source of income. [0003] The Norwegian Authority has also set limits on when manure can be spread, and it is not allowed on snowy and icy land. This means spreading manure over the winter is not allowed, and the farm's compost field must be large enough to store all the manure produced during this time. [0004] Manure from farm anim...
