The market for sand and gravel aggregate demand continues to increase driven by the widespread distribution of sand and gravel production equipment. Henan Hongxing Mining Machienry Co., Ltd. as domestic famous mining, crushing and screening equipment manufacturers, and production of the PF series impact stone breaker much market favor .Impact crushing machine can be widely used in the the hydropower highway stone production line, the rotor body of sleeve connection with keyless , efficient and wear plate hammer, insert the installation form, tilt bearing unique tooth counterattack lining rack multi-faceted open the door, screw or hydraulic opening device so that replacement wearing parts , maintenance is more convenient. Crushing counter-attack function deal with the side length of 100-500 mm of the following materials , the compressive strength of up to 350 MPa, with broken than large , the material was broken cube particles, etc., crushing compression strength not more than 350MPa hard rock, crisp grain material , especially suitable for the the highway hydropower project, the use of aggregate, fabric and artificial sand, the crushing of hard materials such as basalt, river gravel, granite, hard lime.Hongxing Machinery developed its own production of the pp series stone impactor than larger, more simple structure , run more smoothly, more efficient work, etc., it is simple maintenance, change convenient decisive advantage of leaving the impact breaker to be a lot of investment favor objects are widely used in building materials, mineral processing, chemical and power sectors . It is the most satisfactory and the Heart of Hongixng Machinery on the quality of service requirements, has been praised by the industry and the general user. The Hongxing Mechanical impact stone breaker is a heavy-duty rotor design, a perfect combination of high wear-resistant materials, as well as the design of the…
