试验室NJ2型粘结指数测定仪技术参数
Technical Parameters of Laboratory Coking Index Determinator
以一定量的煤样与一定量的无烟煤(惰性物质)混合均匀,使得煤样(小粒度)均匀地附着在无烟煤(大粒度)的表面,干馏过程中煤样生成的胶质体将无烟煤的颗粒粘结在一起,然后用特制的转鼓做转磨试验,以测定焦碳的耐磨强度。以此来判断煤样(煤中胶质体)对无烟煤的粘结能力,再运用特定的公式来计算出煤样的粘结性。
用途:用于测定炼焦用煤的粘结能力—罗加指数及粘结指数
特点:
1.计数准确、操作方便。 2.转数可任意预置。 3.开机自动复位。 4.混合煤样按国标自动搅拌。
Uniform blending of coal samples with anthracite( inertia substance ) is made in certain amounts, allowing the coal samples ( small size fraction) to evenly attached to the surfaces of anthracite(large size fraction). Colloids produced by anthracite in the process of distillation to be bonded with particles of anthracite are subject to grinding tests with rotating drum for measuring abrasion strength of coke , on which ability of bonding of the coal samples (colloids in coal) to anthracite can be judged and the cohesiveness of the coal samples can be calculated using the special formula.
Use: It is applied for measuring bonding ability of coal for coke , Roga index and coking index.
Features:
1、Accurate counting and simple operation
2、Pre-setting of number of rotation randomly
3、Auto-reset after start-up
4、Blended coal samples being automatically agitated as per the relevant national standards.
