Ton production, processing complete sets of processing equipment, main products: E-type, hammer, roller, counter-style, vertical crusher, and highly efficient energy-saving cone bearing Mill Park, shaker, automatic anti-sand-a spiral -, And highly efficient energy-saving flotation machine, mixing tank mine, Feeder, thickener, mine upgrade, conveyors and other equipment.

生产日处理5-1000吨级成套选矿设备，主要产品有：鄂式、锤式、辊式、反击式、立式破碎机、高效节能园锥轴承球磨机，振动筛，自动反砂螺旋分极机、高效节能浮选机、矿用搅拌槽、给料机、浓缩机，矿用提升、输送机等设备。

A flowsheet consists of three stages of fine grindings,two stages of gravity separations and a screening process was adopted to recover iron from iron-smelting slag ,and reduced iron powder with MFe exceeding 90% can be prepared.

为了有效回收炼铁渣中的铁，对炼铁渣进行三级细磨、二级重选以及一段筛分处理，制得了MFe含量90%以上的还原铁粉，实验表明2 t粉铁可制取出1 t还原铁粉，残渣则可用于制作陶瓷、免烧砖等，实现了资源综合利用。

ZZS series shake frame flat screen apply to removing section and coarse select ofmechanical wood pulp ,sulphate wood pulp ,straw pulp and wasted paper,etc,during the procedure of make thick liquid extensively.

ZZS系列振框筛广泛用于机械木浆、硫酸盐木浆、草浆及废纸等制流程中的除节和粗选。你知道它的英文吗？

The technology of water washing can remove all above-mentioned harmful impurities except of P〓O〓 in crystal lattice. However, the feasibility of water washing technology may rely on the ability in investment as the initially required investment size is big. Also, this technology may cause a secondary pollution as the process generates large amount of waste water. Organic matters can be removed by a floating technology. Lime may be used as a neutralizing agent which transforms watersoluble P〓O〓, F〓 into salts of low solubility. Grinding can improve the crystal morphology and the gradings of PG. A combined technology of neutralization with grinding may have the advantages of both.

水洗可除去除共晶P〓O〓以外的所有杂质，但存在一次性投资大、工艺复杂、污水排放造成二次污染等问题；浮选可除去磷石膏中的有机物；石灰中和使有害态的可溶磷、氟转化为惰性的难溶盐；适当的球磨可有效改善磷石膏的颗粒形貌与级配；筛分可除去有害杂质含量特别高的部分，提高磷石膏品质；球磨与石灰中和结合的预处理工艺，既消除了主要有害杂质的影响，又改善了磷石膏颗粒结构与级配。

Itsprocessing craft relative is simpler, including the raw materialchoice, the clean, the selection, goes to the skin, goes to thenucleus, goes to the stem, brokenly, presses out the juice, sievesfilters, the sterilization, cooling, mixes,isotropically, the vacuum degasification, the sterilization, canned,the seal, cooling and so on various steps.

其加工工艺相对较简单，包括原料挑选、清洗、拣选、去皮、去核、去梗、破碎、榨汁、筛滤、杀菌、冷却、调配、均质、真空脱气、杀菌、罐装、密封、冷却等各步骤。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
