rock crushing: the rock is the study of rock composition, texture and structure disciplines, occurrence, distribution, origin, evolution, and its relationship with the mineralization and the like. Geology branch. Rocky meteorites, lunar rocks and other cosmic sources, but also the study of petrology. Science is often divided into rock petrology and petrography. The main causes of the former rock in the early genesis of multi-finger associated with igneous rocks; latter is mainly to identify the composition and structure of the rock structure, characteristic of rock description and classification, also known description petrology or petrography. silica sand washing machine: Following the country's first pilot project of silica sand production line located in Panyu, in the perspective of many cement companies in transition into the steering mechanism gravel field, while the use of river sand, sand and other natural sand aroused great attention once again With the utilization of natural sand to raise standards and mechanisms to improve the cleanliness of sand, sand washing equipment-related and therefore increase demand. Sand washing equipment generally consists of a belt conveyor, spiral sand washing machine or wash bucket wheel sand bodies into, is the main equipment of sea sand and river sand taken. This device is suitable for sandy soil with high volume, more sandy gravel, sand, after the original screening crushed stone into the crusher and then washed with water, washed the sand clean, screening can be completed simultaneously, the separation process, a one-time production qualified products can be divided into sand, pebbles, the pebbles. cost of artificial sand in tamilnadu: artificial sand is professionally gravel crushing machinery, sand making equipment, processing, screening made of rock particles size less than 4.75mm, but does not include particles of soft rock, weathered rock. Artificial sand and natural sand with some differences, but the quality of the applications no way inferior to natural sand, while the cost of production also has certain advantages, therefore, has become a hot trend in the current investment and development. Meanwhile, sand production line to improve efficiency and reduce the cost of a coup. It features sand production line is effective to use, effective use of sand production line of features to enhance the yield and lower production costs is of great help. The use of professional crusher, sand making machine and other mechanical equipment will be all kinds of rocks, minerals, construction waste, tailings and other production granularity qualified, with reasonable level of gravel aggregate, usually sand or mechanisms become artificial sand. Mechanism of sand compared with natural sand, the drawback is not present, the difference between how much over the years, the domestic industry experts, technical staff, front-line workers in construction and other industries who have done a lot of experiments with this application proof of their quality and Cost has the same advantages as natural sand, even through manual control, after screening washing, its quality is better than natural sand mining. cost to setup mini cement plant in india: Cement should establish common modern equipment spare parts management emphasized that the integrated management, especially in the economic management. Have set up a cement plant spare parts workshop, not only cause human waste, and there is spare reserve quota is too large, repeat reserve, spare parts turnover longer occupy a lot of liquidity in the corporate malpractice. According to state regulations, spare reserve funds accounted for only 2% to 3% of the original value of fixed assets equipment. According to incomplete statistics, this year before the workshop cement plant spare parts warehouse plus reserve funds for more than 1.5 million yuan, has seriously hampered the economic development. As the implementation of the whole plant General Parts centralized supply system, the benefits of the following five points: 1 occupies the liquidity greatly reduced. Since the whole plant of the same model, a larger number of devices of the same type, the whole focus on the supply of spare parts GM plant, can greatly reduce the spare parts reserve quota to ensure that spare parts reserve funds does not exceed 2% to 3% of the original value of fixed assets 2 can be improved Spare utilization, accelerate the turnover of spare parts reserve funds. Spare reserves the workshop itself, because the equipment models and more inevitable large reserves of spare parts; Also, because the same model less equipment, spare parts utilization inevitable low. So do not inevitably lead to long-term backlog of spare parts, spare parts turnover so slow. A cement plant individual workshop using common sparing none of ten years, but already have apportioned the cost.
