Roller tooth of toothed roller crusher

Abstract

The invention discloses a roller tooth of a toothed roller crusher. The roller tooth comprises a tooth head, wherein a boss is formed in the upper part of a stress surface of the tooth head; integrally connected wear-resistant metal is arranged on the boss; an integrally connected protection table is arranged at the lower part of the tooth head; a mounting hole is formed in one side of the protection table; an integrally connected tooth handle is arranged at the bottom end of the protection table. The roller tooth of the toothed roller crusher is simple and smart in structure; the boss at the upper part of the stress surface of the tooth head is capable of effectively gripping ores, thus greatly improving the crushing efficiency; the integrally connected wear-resistant metal is arranged on the boss, thus effectively reducing the consumption of noble metal and saving the cost; the extended protection table is arranged at the lower part of the tooth head, thus protecting the roller surface and omitting the protection of the surface of a roller body; the mounting hole is formed, so that the roller tooth of the toothed roller crusher is simple to process and mount, time-saving and labor-saving effects are achieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of crushers used for crushing mineral products, in particular to the teeth of a toothed roller crusher. Background technique: [0002] With the rapid development of my country's economy, the scale of infrastructure construction is huge. The demand for building materials will be staggering. China is also a country with a large demand for mineral products. The mineral product processing market has broad prospects. At present, in China and even abroad, the crushing and processing equipment of mineral products has been hovering in the "one low" and "three high" of low efficiency, high energy consumption, high wear and high pollution. For example, "hammer crushers" and "impact crushers" have always been equipped with high power, heavy machine wear, low efficiency, high noise, and serious dust pollution. However, the old-fashioned "toothed roller crusher" still has defects such as complex structure, high consumption o...

I applied for the patent No. ZL201020628553.9 and ZL201120485478.X on November 26, 2010 for the toothed roller crusher patent. There are a lot of materials, the cost is high, and there is no boss on the upper part of the force-bearing surface of the roller teeth, so the breakage rate is relatively low
