The molded pulp machine (JZC2-9894) used in this study is fully automatic. To improve the mechanical properties of pulp molding while maintaining a good uniformity of pulp molding, we added a certain proportion of bamboo pulp fiber to the bagasse pulp. The proportion of raw fibers was 70% bagasse pulp and 30% bamboo pulp.

ELMo: Embeddings from Language Models¶. Word embeddings such as word2vec or GloVe provides an exact meaning to words. Eventhough they provided a great improvement to many NLP task, such "constant" meaning was a major drawback of this word embeddings as the meaning of words changes based on context, and thus this wasn't the best option for …

The breakage index equation (BIE), or t10 model from drop weight testing (DWT) data for rocks and ores is used in the design of crushers and mills. Such models are becoming increasingly difficult to visualize as the number of variables increases. The so-called double fan BIE, combined with the Swebrec distribution's accurate description of the sieving curves, is applied to the …

A modified carbon paste electrode with Sn(II)-exchanged clinoptilolite nanoparticles (CNP-Sn(II)-CPE) showed voltammetric current (in cyclic voltammetry (CV)) for Sn(II)/Sn(IV) in sulfuric acid electrolyte (pH 2). The peak current was decreased when bromate was added to the solution. Hence, this decrease was used for indirect voltammetric …

To determine the power that a dry grinding needs, full grate discharge mill Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is

The second one is for calculating the surface finish of a normal ball nose end mill. If you used the first calculator you would put the diameter that it gives you and use it as the diameter in the second one. The real beauty of the second one is that if you input a diameter and surface finish, it will inversely calculate the step over for you.

(1). As an estimate, we can use the famous Blasius equation: fl4 = 0.O791/Reu4 (2) where 4 converts from Darcy to Fanning factors. Eq. (2) is valid for Reynolds numbers between 2,100 and lo6 for hydraulically smooth pipe (E/D = 0). This simple equation is useful for making estimates for a range of 0.0178
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.
