The utility model discloses a kind of grinding plate tooth shape structure, which includes the body of the grinder. The grinding plate is divided into three regions, from the outside to the inside is the fine grinding area, the semi fine grinding area and the coarse grinding area. The surface of the grinding plate has a number of teeth on the external surface, the width of the fine grinding area is 80mm - 160mm, and the width of the semi finishing area is 40mm - 100mm, the width of the tooth profile is 1.5 - 2 times the width of the tooth profile in the fine grinding area. The width of the alveolus is 2 - 3 times the width of the alveolus in the fine grinding area, and the width of the coarse grinding area is 80mm - 160mm. The width of the coarse grinding area is 3 - 4 times the width of the fine grinding zone. In the rough grinding area and the fine grinding area, the semi fine grinding area is added, and the tooth type structure is designed to increase the tooth type strength and not easy to beat. The material has been further broken and grinded before entering the fine grinding area, which reduces the grinding strength of the fine grinding area, thus improves the life of the grinding plate and improves the quality of the fiber. Because the alveolar width of the semi fine grinding area is 2 to 3 times that of the fine grinding area, the resistance of the material flow is reduced, and the power consumption of the mill is reduced.

一种性能兼顾的磨片齿形结构
本技术涉及人造板行业,具体为一种性能兼顾的磨片齿形结构。
技术介绍
磨片设计选用合适的齿型以达到既定的打浆参数,还必须具有良好的耐磨性能和抗冲击韧性。纵观100多年来,全球范围的磨片制造和使用的发展中,石材、灰口铁、镍硬白口铁、高铬铸铁、镍铬合金、多元合金、不锈钢、碳化钨、高分子聚乙烯、改性尼龙、陶瓷、金刚砂等材料都得到过采用,鉴于耐磨性和经济性考虑,目前多元合金磨片和高铬铸铁磨片因良好的耐磨性能处于主导地位。具有表面粗粒的多元合金磨片倾向于对纤维更好的分丝帚化作用;特钢磨片倾向于纤维更剧烈的切断作用。人造板磨片是热磨机的磨削工具,利用磨片将木片磨成纤维状,再添加辅料压制成板。磨片性能指标主要是:耐磨寿命长、加工出来的纤维质量好、磨机功耗低、齿型强度高;磨片上按一定规律布满各种齿型,传统齿型磨片的齿型分为精磨区和粗磨区,精磨区齿型细,宽度一致,保证纤维质量。粗磨区齿数少,齿型宽,兼具拨料和粗磨作用。磨片的使用寿命除了和磨片的材料、热处理有关外,与磨片的齿型也有很大的关系;纤维质量和磨机功耗主要与齿型有关;齿型强度与磨片材料及热处理和齿型 ...
