制砂机（高效细碎机）是我公司专家结合 的工况条件好新设计的成果，是目前国内具有 先进水平的高性能制砂机设备。该机专为高速公路、高速铁路、高层建筑、市政、水电大坝建设、混凝土搅拌站提供优质砂石骨料，是人工制砂和石料整形 域的 选设备。

          Sand making machine (high efficiency fine crushing machine) is the result of good design of working condition combined by experts of our company. It is the advanced high perbance sand making machine equipment in China at present. This machine is specially designed for highway, high-speed railway, high-rise building, municipal, hydropower dam construction, concrete mixing station to provide high quality sand and gravel aggregate.

     高效细碎机结构设计原理由“石打石”粗碎腔、细碎腔、契形可调节反击板和圆弧板构成的冲击腔，以及三个排料通道组成。具有以下特点：出料粒度可任意调节，调节板可两头翻面，寿命增长，调整更容易，不卡、不堵、退让性好，安全性更高。锤头可四面使用，利用率高，浪费小。独特的调节功能，使反击板和筛板的调节更有效，方便，从而可控制物料的出料粒度，使所需的物料粒度可达95%以上，实现比较理想的物料粒度控制、分级。PXJ制砂机（高效细碎机）的研制成功，彻底改变了细碎、制砂行业长期困拢的制成品粒度差、粒形不规格等问题，解决了细碎、制砂设备锤头磨损大，调节，维修困难，从而造成生产成本偏高之缺陷。大幅度提高了高效细碎机的时产量，降低了能耗，使所生产成品质量达到或超过 标准。PXJ制砂机（高效细碎机）自推向市场以来，改变了制砂行业的“铁砂”这一怪象，扭转了制砂企业微利或亏损状况，得到了使用厂家的高度赞扬。

The design principle of high efficiency fine crushing machine structure is composed of "stone crushing" rough crushing cavity, fine crushing cavity, impact cavity with adjustable wedge and arc plate, and three discharging channels. It has the following features: the discharge particle size can be adjusted arbitrarily, the adjustment board can be rolled at both ends, the service life increases, the adjustment is easier, not stuck, not blocked, the concession is good, the security is higher. Hammer head can be used in four sides, high utilization rate, small waste. The unique adjustment function makes the adjustment of the counter plate and the screen plate more effective and convenient, so as to control the grain size of materials, make the required grain size of materials reach more than 95%, and realize the relatively ideal material grain size control and classification. The successful development of PXJ sand making machine (high-efficiency fine crushing machine) has compleby changed the problems of poor grain size and non-standard grain shape of finished products that have been trapped for a long time in the sand making industry, and solved the problems of heavy wear, adjustment and maintenance of hammer head of fine grinding and sand making equipment, thus causing the defects of high production cost. The output of high efficiency fine crushing machine has been greatly increased, energy consumption has been reduced, and the quality of finished products has been achieved or exceeded the standard. PXJ sand making machine (high efficiency fine crushing machine) has changed the phenomenon of "iron sand" in the sand making industry since its introduction to the market, and reversed the marginal profit or loss of the sand making enterprise, which was highly praised by the manufacturer.
