River sand, natural sand in the building has a lot of advantages, but with the improvement of the indicators required by the building, natural sand due to geographical differences in the distribution and generation of natural weathering conditions, and physical and chemical indicators showing volatility, which for concrete, especially high performance concrete is certainly not conducive to the stability of quality. Most importantly, with a significant reduction in infrastructure development and river sand resources, and the state strictly limited dredging sand, so finding new sand source is a priority infrastructure. Sand also known as impact crusher, Barmac US companies use the famous "stone at stone" crusher works and production technology, combined with sand production technology at home and abroad to develop out of the situation with the international advanced level stable performance, low emissions equipment, its performance in a variety of fine ore broken equipment can not be replaced, and the most effective, practical and reliable. The crusher is used in construction sand, road sand, asphalt concrete and cement concrete aggregate ideal production equipment, can be used for transportation, construction, etc; in the field and is an indispensable machine. It is suitable for crushing soft or medium hard and extremely hard materials, shaping the third generation of Sand, is widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone and a variety of metallurgical slag, has been widely used, especially for silicon carbide, silicon carbide, sintered bauxite, the US high sand hard, special hard and abrasion resistance material is higher than other types of crusher production efficiency. The basic principle of a stone sand stone, stone blacksmith, or a combination of both methods. Yuxin Senda following combination provides the latest Heavy Sand 5X Sand introduced the sixth generation of its overall operation. 5X Sand manner in accordance with the feed in two ways: with a central waterfall drop feed, feed the whole center. Feed the whole center. Through the central feed hole into the high-speed rotation of the rotor after being fully accelerated and thrown back by launching mouth Sand, the first part of the material with the rebound after a free-fall was hit, and then went to the impact of the surrounding swirling vortex chamber Feeding lining (or back on the block) vsi crusher, the first to be bounced back to the top of the crushing chamber, after deflected downward movement, and the material emitted from the impeller material impact to form a continuous curtain finally discharge through the lower discharge port. The third generation of Sand, Sand, Guizhou, Henan by Henan new Senda Heavy Machinery Co., Ltd. The new Senda. Henan new Senda Heavy Machinery Co., Ltd. (www.hnsdzg.com) strong, credible, in Zhengzhou crushing grinding equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Yuxin Senda and you hand into the brilliant, for a better future!
