Description

[0001] MULTI STAGE-PELLET MATERIALS GRINDING APPARATUS [0002]

The present invention relates to a multi-stage pellet mill, and more particularly, to a multi-stage pellet mill for grinding pellets, which can prevent malfunction in the grinding process of the pellets to form the pellets, The present invention relates to a multi-stage pelletized raw material pulverizing apparatus capable of improving the yield and facilitating easy separation and maintenance.

Grindable fibrous materials such as sawdust, leaves, sugarcane stalks, corn stalks, reeds, chaff, raspberries, rootstocks, grasses, twigs, tree roots, and wood pulp are compressed to high pressure and made into particles of a certain size And transportation. However, since it is not well formed at present, it is used in the form of feed, fertilizer or fuel (firewood) as it is in its natural state.

In other words, due to the problem of processing by the volume of the raw material, an additional process such as forced compaction or crushing is required in order to reduce the volume of the raw materials. That is, since the raw materials have many fibers in the natural state and are not tacky, they can not be pelletized by themselves. In order to mold the raw materials into a pellet mill, the particle size must first be small and uniformly pulverized, and then a viscous material is mixed with an auxiliary raw material and molded in a pellet mill. The viscous material may be a starch solution and may be a raw material containing high moisture such as food waste or manure.

For example, in Korean Patent No. 443899, food waste is crushed to a size of 10 mm or less through a crusher, the crushed food waste is put into a kiln type dryer, and the dried moisture content is finely crushed to 3 mm or less Next, the pulverized food waste and the sawdust were mixed at a ratio of 7: 3 in the mixer, and the mixture was poured into a pellet extruder for extrusion molding. The extrudate was cut, And secondary drying by indirect heat of ~ 60 ° C to greatly reduce environmental pollution and to obtain a high added value at a low fuel consumption.

In Korean Patent Application No. 2002-28770, the pulverized rice husk powder and livestock manure are mixed in a range of 10-20 mesh at 50% ~ 70%: 30% ~ 50%, and after completion of the mixing step, The fermented mixture is put into the fermentation tank and fermented at a temperature of 50 to 70 ° C for 20 to 24 hours to regulate the occurrence of hyphae. The fermented mixtures are then post-fermented at room temperature for 14 days to 21 days, And then the mixture is taken out through a crusher in the form of a fine powder to prepare a pellet, and the pellet is processed into a spherical shape.

Conventionally, however, the pellet can not be smoothly pulverized during the pellet milling process, and the milling and crushing path of the crushing mill are blocked, thereby causing a trouble of the device.

In addition, in the case of pulverization raw materials containing water in the past, there is a problem that the water does not completely dry and clumps together to form a lumpy shape, and the resulting pellets are easily broken or subjected to a separate drying process There is a problem in that it is inconvenient for the user.

The dispersing member 200 is formed in an inverted V shape and is fixed to the upper inner wall of the housing 100 through the fixing rod 201. At least one pellet material through-hole 210 is formed in the dispersing member 200 in the vertical direction or diagonal direction. In FIG. 2, the pellet material through-hole 210 is formed in a vertical direction.

The dispersing member 200 is inserted into the pellet feed hole 110 of the housing 100 while spreading the pellet feed through the pellet feed hole 210 formed in the dispersing member 200, Into the room or to be inclined and fall into the crushing unit (400).

The driving unit 300 is for driving the grinding unit 400 which is received by an external driving source (for example, a motor driving source) and is fixed by the tensioner 500. For example, the driving unit 300 includes a worm gear assembly A rotation shaft 320 coupled to the worm gear assembly 310 and a cam nut 330 for fixing the protruding end of the rotation shaft 320 protruding from the upper portion of the tensioner 500.

In this case, the cam nut 330 is formed to be round in shape, thereby preventing the foreign materials including the raw pellets from being easily caught, and can be easily removed even if foreign matter is caught.

The grinding unit 400 includes a grinding plate 410 having an outer edge fixedly secured to an inner wall of the housing 100 and having a plurality of holes formed over the entire surface thereof to discharge pellets to be pulverized, And a milling roller 420 that receives the force and applies a pressing force to the grinding plate 410 to crush the pellet material on the grinding plate 410.
