Single roller crusher sand with small 16O0mmx27O0mm single roll crusher, this transformation single roller crusher specifications remain unchanged, to gear, the tooth structure and configuration improvement and perfection: a spiral arrangement of the tooth, to overcome the sintering machine intermittent shock loads caused by the discharge, so that the work load evenly, the impact of a small motor, a smooth start new Sand, low energy consumption. IMPROVED hammerhead form structure, enhance the hammer breaking capability, ease of welding surface wear-resistant materials, improve the wear resistance, thereby increasing the life of the hammer. 3 shaft and bearing are water-cooled to reduce the thermal deformation. 4 multi-level signal control, in order to grasp the emergency stop time, to facilitate timely maintenance. 5 optimization process configuration Sand, rational arrangement of space under the material to ensure a smooth discharge. The main advantages and features of Sand primarily in the following areas: high crushing efficiency, with a crushing, coarse grinding function; simple structure, installation, easy maintenance, low operating cost; large product bulk density, minimal pollution; through non-broken material ability, moisture content of materials subject to little effect, the moisture content up to 8%; excellent product shape, a cube, flakiness content is very low, suitable aggregate shaping, artificial sand and highway aggregate production . Waterfall falling into the material feed size is larger than when the second impeller feed particle size, it needs feed from two feed ports respectively. Ore hopper into the river gravel crusher, respectively, through the feeder center feeding tube into the impeller, when the material into the high-speed rotation of the impeller, the impeller being rapidly accelerated in its acceleration up to several hundred or even several times the acceleration of gravity, and then at a rate of every 70-100m / s from impeller projectile out, first with a free fall into the cavity eddy broken impeller material impact outside broken, and with the impact of eddy crushing cavity material bed layer, is sprint onto the bed material rebound oblique whirl at the top of the crushing chamber, but also to change its direction of motion, deflected downward movement, rotation Road, emitted materials from the leaves form a continuous material curtain, so a piece of material in the turbine broken twice by the cavity as well as the impact of repeated crushing action. Throughout the crushing process, the material is self-reciprocal impact crusher, not in direct contact with the metal element. Since the road from the impeller emitted material oblique peripheral impact, forming material whirl crushing cavity material rotational movement on the bed, resulting vortex motion between the grinding action of material, due to the impact between friction and grinding materials, the crushed material is discharged from the discharge port. Henan Senda Heavy Industries of river gravel crusher with high performance stability, reasonable structure, high degree of automation, the entire production line in addition to power down equipment and routine maintenance, is simple and almost no manual operation and other advantages, important is its high production efficiency counterattack Sand, low operating costs, production crusher manufacturers, high-yielding, finished stones uniform size, grain shape is good, in line with national high-speed material requirements. The third generation of Sand, Yuxin Senda (certification), Dehui Sand by Henan new Senda Heavy Machine Co., Ltd. Henan new Senda Heavy Machine Co., Ltd. (www.hnsdzg.com) is a leader in Zhengzhou, crushing grinding equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In Yuxin Senda leadership with the staff warmly welcome all inquiries negotiations to create Yuxin Senda better future.
