This discharge port plate inner face is sphere shape, and is provided with at least one discharge opening;

Offer at least five discharge openings on this abrasive sheet.

The utility model is by the external spiral cover, the spindle nose overcoat, the central rotating shaft of inside spin axle and butt joint is with it formed, utilize the external spiral cover of this bulking machine and the structural design of inside spin axle, forming not, the extruding of equidistant non-standard spiral system advances, gas in the object is discharged from, and filled by material rapidly, object is subjected to the shearing force effect and produces backflow, pressure in the machine thorax is increased, along with the friction between spiral, material is fully mixed, extruding, heating, add hot gluing, gelatinization and produce tissue and change, original structure is subjected to fragmentation, pressure became normal pressure by high pressure when simultaneously mechanical energy was extruded to outlet by material, became normal temperature by high temperature moment, caused moisture content promptly to be evaporated from institutional framework, make the countless microcellular structure of its inner formation, cool off expanded shaping then, this structural design compactness is rotated flexibly, make its efficient height thereby solved, cost is low, and is sturdy and durable, the technical problem that the stable drive noise is low.

The utility model is simple in structure, and its advantage is as follows:

1, the utility model structural design compactness, the production efficiency height, cost is low, adopt to do expanded autothermal process, and the feed nutrition of producing variation is little, digestibility is high, safe and harmless, is particularly suitable for user's needs.

2, the utility model is sturdy and durable, and fault rate is few, stable drive, and noise is low, and is simple to operate easy to maintenance.

3, the utility model adopts all steel and critical piece to finish long service life through the heat treatment manufacturing.

4, the utility model power is little applied widely, can drive with 7.5 kilowatt motors, the particularly suitable rural area does not have the place of three phase mains, gets final product with power drives such as four-wheel tractor, diesel engine, hand tractor more than 12 horsepowers, install simple and convenient, and tool practicality.
