Grading crushing machine

Abstract

The invention discloses a grading crushing machine. The grading crushing machine comprises a feeding opening, a discharging opening as well as a crushing cavity, a crushing assembly and a power device of a sieve screen, wherein the crushing assembly comprises a turntable with a hammerhead, the turntable is installed in the crushing cavity, the turntable is provided with crushing teeth, the crushing cavity is provided with crushing grooves matched with the crushing teeth, the crushing grooves are arranged along the radial end surface of the side inner wall, the hammerhead is arranged on the outer circumferential surface of the turntable, furthermore, an inlet of the crushing groove is communicated with the feeding opening, an outlet of the crushing groove extends to the outer circumferential surface of the turntable, furthermore, an inner gear ring is embedded on the inner wall of the crushing cavity, the inner gear ring is provided with a crushing gear bar, a grinding cavity is formed between the crushing gear bar and the hammerhead, materials are primarily ground by virtue of the crushing teeth and then conveyed to the hammerhead by virtue of the crushing grooves, the materials are further refined by virtue of the hamming of the hammerhead and then ground by the grinding cavity, so the raw materials are broken level by level, the refining of the raw material particles can be accelerated, so that the operation efficiency can be improved; multilevel crushing can be realized in one crushing cavity, the crushing effect is good, the size is small, and the occupied space is small.

Description

technical field [0001] The invention relates to a pulverizer structure, in particular to a graded pulverizer suitable for grinding and pulverizing materials such as grains, fodder, fruits and vegetables, and medicinal materials such as whole grains, stems and grasses, ores, pearls, dried herbs, and dried medicinal materials. Background technique [0002] The most common pulverizer on the market is a single-stage pulverizer, which achieves pulverization through relative movement between a fixed toothed disc or a fixed pulverizing hammer head and a movable toothed disc or a movable pulverizing hammer head. For example, a hammer-type pulverizer usually includes a crushing chamber, a hammer-type rotor is arranged in the crushing chamber, a sieve is arranged on the outer periphery of the rotor, and a feeding port is provided above the crushing chamber, and the feeding port is connected to the crushing chamber through a gap on the upper part of the sieve; When working, the materia...
