How to judge the reasonableness of grinding body gradation?
The reasonable gradation of grinding body is temporary and can only keep stable in a relatively long time, and the length of time is related to many factors, but the key is the grindability of the grinding body itself. How to judge whether the gradation of grinding body is reasonable can be judged synthetically according to the following aspects. (ma 'anshan longsheng wear-resistant materials co., LTD.) to see the mill running current. In the control range, low current, insufficient grinding...
Knowledge of mill for ore dressing: basic types of mill for ore dressing in mines?
Basic types of mineral dressing and grinding machines? I. specification presentation method of grinding machine: Diameter length, denoted by symbol D L, if 2100 3600 ball mill, then its diameter is 2100mm and its length is 3600mm. Ii. According to the different media of the mill, it can be divided into: Medium for steel ball or cast iron ball, it is called ball mill; (2) medium for steel rod called rod mill; (3) the medium for gravel called gravel mill; (4) with their own ore as a medium called...
What kinds of heat treatment process can improve the wear resistance of high manganese steel?
1. Conventional heat treatment process for high manganese steel Normal heat treatment: 1000 ~ 1100 ℃ heating, heat preservation or heating to 650 ~ 700 ℃ heat preservation for a period of time and then heating to 1050 ~ 1100 ℃ and then quenched. Large, of which the thickness disparity, complicated shape in 650 ~ 700 ℃ heat preservation for a period of time, is good for reduce the deformation and cracking, and of uniform thickness, shape, simple not easy cracking of the small,, no heat...
How to choose wear-resisting lining board, screen board material and heat treatment technology?
(1) heat treatment process of sieve plate of high chromium cast iron sinter? Sinter sieve plate is working under severe conditions of abrasive wear, consumption, import the service life of the sieve plate, about 60 days, homemade sieve plate, about 40 days, mainly due to the low domestic sieve plate hardness, eutectic carbide quantity is less, particle rough, uneven distribution, in a large number of sinter under the constant collision and friction of sieve plate tissue deformation, furrow pit,...
