Dust pollution should pay special attention to the wear of the jaw crusher

The jaw crusher is the first choice for the crushing of ore in the gravel production line. In the gravel production line, the jaw crusher is generally used for coarse crushing of ore. Compared with the general ore crusher, the jaw crusher can be broken. The ore is relatively hard and has a relatively large feed. Due to the harsh environment of the jaw crusher during use, the crusher manufacturer reminds the users to pay attention to it, and it is necessary to pay attention to the dust pollution problem of the jaw crusher. In order to reduce the dust caused by air leakage from the crusher casing, in actual production, when the material is dry, water is often poured at the inlet of the crusher. In fact, this situation is wrong, which will aggravate the bag filter of the jaw crusher. The filter bag and the feeder are clogged. During the falling process of the ore and other materials on the belt conveyor, the air enters the sealed dust hood together with the material, and the dust-containing gas diffuses outside the cover through the gaps and holes in the cover wall. In addition, due to the improper setting of the dust removal point at the corner of the belt conveyor The dust collector has almost no effect on the dust of the lower belt conveyor regardless of the opening and closing. Since the operation of the jaw crusher, the dust collector has not been operated, and the lower belt conveyor has been in the process of dust pollution. When the crushing material of the crusher machine has a large humidity, the elbow portion is easily worn by the dust and the dust particles that are blocked into the dust collector are thicker than the broken dry material, and the bag type dust remover is easy to paste the bag, and the feeder is easy to block. As a result, the ventilation resistance of the bag filter is greatly increased, and the ventilation capacity is lowered, resulting in wear of the jaw crusher.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands
