The equipment selection and configuration and process design of the crushed stone production line have a very important impact on the yield of sand and gravel and the quality of the finished sand. Therefore, many factors should be considered in the selection and configuration of the crushed stone production line equipment, and the choice is suitable for your own production situation crusher equipment. So, as a relatively hard material, what kind of crusher equipment should be used to crush diabase into various specifications of stones?
First consider the type and hardness of the gravel master batch, whether it is limestone, granite, river pebble, diabase or basalt, the rock's Mohs hardness (a rock with a Mohs hardness of 7 or more), and whether the rock is soft or brittle hard and brittle, soft and brittle crushing uses jaw crushers, impact crushers and hammer crushers or box crushers (heavy hammer crushers), etc. Hard and brittle crushing requires cone crushers and shaping crushers.
The second is to consider the performance (crushing ratio) and applicability of the crusher. The jaw crusher has a large crushing ratio, squeezing and crushing, and the discharge has many needles and flakes, which is suitable for coarse crushing; cone crusher, impact crusher, hammer crusher. The products of the type crusher and impact crusher have good grain shape and are suitable for medium and fine crushing. Impact crushers and hammer crushers are suitable for the crushing of medium-hard and below-hard stones, and cone crushers and plastic crushers are suitable for the crushing of medium-hard and above-hard stones.
Once again, the output is considered, which requires better matching between equipment. The final output is related to the equipment of the entire production line. For example, if the output is required to be 500t/h, the hourly output of the sand making machine must not only reach 500t, and the processing capacity of the front jaw crusher, cone crusher, belt conveyor, etc. must also be matched, otherwise the final output will definitely not meet the requirements.
Finally, consider whether there is a special quality requirement standard for the crushed stone. If the crushed stone is required to be of high size, it needs to be shaped, and a shaping crusher should be configured. The complete set of crushing production line equipment mainly includes vibrating feeder, jaw crusher, cone crusher, impact crusher, vibrating screen, belt conveyor, dust removal equipment, centralized electric control and other equipment. Sometimes due to processing needs, plastic crushers can also be equipped. The hardness of diabase is above 6.5 on Mohs. Cone crusher with laminated crushing principle can be selected. In addition, according to the requirements of finished materials, it can be used with sand making machine.
Diabase is a relatively hard material. In order to reduce the abrasion of equipment, the following crushing equipment is recommended for crushing diabase:
It is recommended to use JC series jaw crusher for coarse crushing. This jaw crusher is coarse crushing processing equipment. The crushed material has a hardness of 320MPa. It is made of special materials with strong wear resistance and has a deep "V"-shaped crushing cavity. With large feed volume, it can also effectively prevent the material from splashing outside.
It is recommended to use HPY series multi-cylinder hydraulic cone crusher for medium crushing. The cone crusher is mainly suitable for crushing high-hard materials and laminating crushing to minimize the wear of the equipment. The unique thin oil lubrication system design improves the service life of the equipment. The seal has no wear, which improves the reliability of blocking dust, and fundamentally eliminates common faults such as oil-water mixing in the cone crusher.
For finely crushed sand, it is recommended to use the PLS series sand making machine (sand shaping machine). The sand making machine is used to process materials with relatively high hardness. The PLS sand making machine is a new type of sand making equipment. The principles of "stone beat stone" and "stone beat iron" have the effects of sand making and shaping. The particle gradation, finished product shape, fineness modulus, particle size and other aspects are more in line with the construction sand standard.
