Hongxing Mining Machinery Co., Ltd

Zhengzhou, Henan, China

We are offering combination crusher. Featurescombination crusher, which can also be called compound crusher, is one of the commonly used machines in crushing production line and sand making production line. Combination crusher is suitable for crushing limestone, clinker, coal and other ores in building material, mine, metallurgy and chemical industry, and the compression strength of the materials to be crushed should not exceed 140mpa and the humidity should not be higher than 15%. working features of combination crusher1. Little influence of the abrading of board hammer or the scaleboard. 2. No setting of grates. 3. Able to crush the materials with high contents of water and mud. 4. Elastic adjusting structure. The uncrushed materials can be discharged automatically, which does no harm to the machine. 5. Long operating life. The bearings arranged flatly can prolong the life of the machine. 6. Unique structure, steady performance, low noise. 7. Easy to repair. working flow of combination crusherraw materials are fed from the top of the combination crusher, and fall into the rotating impeller at a high speed to be crushed. As other materials simultaneously fall around the rotating impeller, the two kinds of materials join together and are crushed by each other. The materials are crushed many times in the impeller of the combination crusher, and are finally discharged from beneath the machine.

We are offering sand making machine. Characteristics of hongxing sand making machine1. High capacity, high productivity--50-500th, the output is 30% higher than that of the traditional sand maker under the same power. 2. Low consumption of wearable parts--- best design of crushing chamber to make it have little friction with the wearable parts, 30% lower running cost compared with traditional equipments, reducing the cost directly. 3. Excellent shape of final products--- cubic products shape, good granularity, reasonable grading, adjustable fineness modulus, especially suitable for artificial sand making and stone reshaping. The practice has shown that the effect of this series sand maker can improve 30% output in the process of sand making and stone reshaping than the traditional equipment. 4. Easy installation and maintenance --- light weight, various installation ways, movable installation; the installation, repair and maintenance are easy, the operation is easy. materials are transferred to sand making machinery from hopper and then they fall into two parts by material-scattering device. One part falls to the impeller which rotates at a high speed from material-scattering device. In the impeller, materials rotate at even higher speed and their acceleration is as big as hundreds of acceleration of gravity, then they are thrown out through three passages of impeller at a speed of 60-70 meterssecond. They firstly hit part of materials that fall from material-scattering device, then strike with materials inside the cavity and its direction of motion changes to downward. The closed circuit forms. Usually, the materials can be crushed to the ones that are smaller than the mesh after three times in the circulation. The crushed materials will be discharged from outlet.

We are offering raymond mill. Structural advantages of hongxing raymond mill1. Driving system of main frame adopts airtight gearing and pulley to guarantee the smooth drive and reliable operation. 2. The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. The crushing of raw material, grinding and packing is an independent production system. 3. The electric control system is controlled centralizely, so the automatcity is high, the people is not needed in the operating room. 4. Main parts of the whole plant are made of cast and steel of high quality. The subtle technics ensures the durability of whole plant. 5. Compared with other milling plants, its passing ratio achieves 99%, which is what other mill can not reach. working principle of raymond millload the stuff for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus ground. after being ground, the stuff is to be routed to the sorter along the wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the product cyclone collector together with airflow and is expelled from the powder output pipe as product. in the grinding chamber, since the stuff may contain moisture to some extent, the heat generated during grinding makes the moisture evaporate. Since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases. In order to enable the grinder to work under negative pressures, the increased airflow is guided to the duster anew sequentially to the atmosphere after purification.

We are offering rod mill. Brief introductionrod mill is widely used in various industrial departments and its performance has reached international advanced level. It is one of the most effective, practical and reliable machines for construction. It is mainly used for the processing of feldspar, quartz, minerals and other raw materials and it can be also applied to the production of abrasives, refractory, cement, steel grit, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt aggregate and other hard, brittle materials. It is an efficient, energy-saving machine when compared with the traditional ones. working principlethe rod mill drives the cylinder in rotation by the engine through the rotation of the reducer and big gears around in deceleration or through low speed synchronous motor driving directly peripheral big gears. The machine is equipped with appropriate grinding medium-steel bar, which is raised to a certain height under the centrifugal force and friction force and then cast down or discharged. The materials to be crushed are continuously added to the cylinder, shattered by the rotating grinding medium and discharged for the next procedure by the overflow and the power produced by continuously feeding in materials.

We offer High Strength Raymond Mill.The machine is used for grinding the barite, limestone, kaolin, ceramics and slag with Mohs hardness below scale 9.3 and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 80-425 (1000 the finest) meshes. It is possible to product 30-80 mesh coarse powder through special device in the machine. Working process: In the main frame, a 100-1500 kg powered pressure spring is fixed to the roller suspender. After the grinder is put into effect, the roller rotates around the main shaft, and rolls closely against the ring pressed by the high pressure spring and centrifugal force. And its rolling pressure ration is 1.2 times higher than that of the raymond grinder under the same power condition and the production output is raised to substantial degree.When a certain degree of wear of roller and ring is effected, it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring. As a result, the stable output and fineness are ensured.
