Stepless gear roller set and stepless gear roller crusher

Abstract

The invention discloses a stepless gear roller set and a stepless gear roller crusher. The stepless gear roller set comprises at least two gear rollers, wherein a gap is formed between the two adjacent gear rollers, and the gap is gradually enlarged from one side to the other side. The stepless gear roller crusher consists of a feed opening, a sorting feeder, the stepless gear roller set, a sieving feed opening, a sieving machine, a coarse material refeeding opening, a discharge opening and a main machine frame. Aiming at overcoming the defects that an existing equipment is complex in structure, is large in size, is high in building cost, and the like, the rate of certified product of particle size after cracking of brittle materials is lower, and the excessive smashing phenomenon is serious, the stepless gear roller crusher is integrated equipment capable of sorting feeding, sorting smashing and sieving. The stepless gear roller crusher has the advantages that the structural design is simple and reasonable, the building cost is low, the floor space is small, the highest particle size certified product rate can achieve about 95%, and the crusher is the most environment-friendly, the most electricity-saving and the most durable.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a stepless toothed roller crusher which combines a feeding system, a crushing system and a screening system, and a stepless toothed roller set thereof. Background technique [0002] For the crushing of brittle materials, the particle size quality rate of manual crushing is about 95%, while the particle size quality rate of mechanical crushing is less than 85%. In order to improve the rate of genuine particle size and reduce labor at the same time, after research, jaw crusher is better than hammer crusher, cone crusher is better than jaw crusher, and roller crusher is better than cone crusher. [0003] The roller crusher is suitable for coarse and intermediate crushing of brittle block materials in cement, chemical, electric power, mining, metallurgy, building materials, refractory materials, coal mines and other industries. It can crush materials with compressive strength ≤ 160MPa...
