According to the matrix theory of comminution, which involves the concepts of the classification matrix and breakage matrix, the mathematical models of roll crushers and rotary breakers of coal preparation plants have been investigated in this paper.For the roll crusher model, the classification matrix is expressed by a certain equation. The breakage matrix is developed firstly by a single particle pendulum breakage test, and then by a computing calculation for the test data using a multidimensional cubic spline regression technique.The rotary breakage involves three subprocesses:prescreening, crushing and, rescreening. The prescreening and rescreening suoprocesses are represented by a simple efficiency curve model. Modelling the crushing subprocess uses the same concept as the roll crusher model, but needs more assumptions. The feed of the rotary breaker is considered to be divided into two components( "coal" and "ash"). These two components have the same classification function but different breakage function. They are also selected for breakage at different rates. The crushing and rescreening subprocesses repeat for several stages.The above two models have been tested using a number of industrial experimental data. It has been found that they can be used to predict the size distribution of crushing products with reasonable accuracy.In addition, an empirical model has been developed to predict the ash content ot the broken coal fractions.

根据粉碎(作用)的矩阵理论(包括分级矩阵和破碎矩阵),本文提出了选煤厂辊式破碎机和选择性破碎机的数学模型。在辊式破碎机的模型中,分级矩阵用一个方程式来表示。破碎矩阵的导出,需先进行单颗粒煤样的摆锤破碎试验,然后用多维三次样条回归技术作计算机处理。选择性破碎机的整个过程由三个子过程组成:预先筛分,破碎和检查筛分。其中,预先和检查筛分的模型用一个简单的效率曲线公式来代表。破碎子过程的模型与辊式破碎机模型的概念类似,但需作进一步的假设:选择性破碎机的入料是纯煤和纯灰的混合物;这两种成分的分级函数相同;它们的破碎函数不同,且进入破碎子过程的选择率也不同;破碎和检查筛分两个子过程是多段反复进行的。经检验,上述两个模型可用朱比较准确地预测破碎产品的粒度分布。此外,本文还提出了一个预测破碎产品各粒级灰分的经验公式。

Experiment research on ultr-fine comminuting mica with high pressure water jet,usingthe priciple of direct injection abrasive jet,has been studied. The nozzle is able to disintegratemica which size is larger than its inside diameter. And the pressure is the most important parameter that affects the effectiveness of comminution with high pressure water jet. The output of fine-size particles increases when the pressure increases and input mica size decreases.The effectiveness of comminution with water jet in submerged state is better than that innon-submerged state. Ultra-fine comminuting mica with high pressure water jet is a practicaltechnique for ultra-fine mica comminution, which can satisfy the demand of pearly micapowder,protecting the sheet structure and mica glossiness.
