Generally 0.512316; 0.9kPa, and is affected by the following factors: 1) the inlet velocity. The pressure loss and the gas inlet velocity is proportional to the square of the. 2) the relative size of coal crusher. Pressure loss with the exhaust pipe diameter decreases with increasing with increasing length of cylinder and cone part and reduced 3) fly ash grinding equipment inner degree of finish.

The rough inner wall will cause the pressure loss increased. the application of fly ash processing equipment of coal crusher has the advantages of simple structure, low cost, easy and convenient installation and maintenance, thus being in low-pressure boiler using, can also be used as a pretreatment device for other high efficiency coal crusher.

In practical application, in order to improve the efficiency of coal removal or flue gas handling capacity and a plurality of coal crusher connected in series or in parallel are used together, to form a combined multi tube coal crusher. The coal crusher is the shortcomings of the coal removal efficiency is low, the cylinder, the cone inner wall is easy to wear and easy to block the ash cone part.

The hardness of the ore, the wear resistance of the vibration sieve to be particularly good, can meet the demand of the production. In the ore production line, generally used for screening large material bentonite manufacturing plant, which are broken again until it meets the requirements.

A small piece of material directly through the vibration sieve, filter out. Because of different ore of sieve surface abrasion degree, for the hard ore, vibration sieve screen surface replacement frequency higher than that applied to soft ore sieve. In view of the screen surface use, operation personnel should pay special attention to the screen surface of the fastening device is fastened. Daily maintenance includes sieve surface vibration sieve, sieve surface fastening situation etc..

Vibration sieve loose shall timely fastening. Vibrating screen is in use process, the operator should regularly clean the screen surface. The paint falls off site, the staff should be promptly repaired, derusting and painting; when processing the exposed surface should be coated with petroleum jelly to prevent rust. In the whole process of the work, the staff should be some attention to the above proposed.

Comprehensive analysis and supplemental test 1, according to the theory of optimal solution is obtained by orthogonal test. The level of the solid liquid reaction to further improve the quality ratio, reaction temperature appropriately reduced, arrange the supplemental test further.

In the near optimal scheme making a round of tests of 2 level of small batch, the reaction time is fixed at 90min, factor A from a higher level of 1:4 than 1:3, factor B from 50 DEG C, the test results show that, the extraction rate was 86% and the theoretical value is not. At the same time verified the test, final test to determine the condition of solid-liquid mass ratio of 1:3, reaction temperature 50 C, reaction time is 90min.

2, vertical impact crusher and wet sieving, filtrate effective recovery, and as a fine tuning agent solution of pH, to achieve material recycling, the maximum value of two times the increase of vertical impact crusher as resource utilization, and reducing the environmental pollution.3, the use of solubility product principle to calculate Fe3 in the solution pH value reaches 4.1 complete precipitation of Al3 in solution, pH value is 3.8 when begin to appear Al (OH) 3 floc, use of the specific conditions of selected pH value 3.8 ~ 4.1 as the cut-off point, with 1mol/L, 0.1 mol/L, 0.01 mol/L,

3 different the concentration of NaOH solution was used as the reaction solution pH coarse, reconcile fine-tuning agent, through the change of digital pH meter control solution of pH readout data effectively and in time value.

In the process of mine equipment work, production capacity is related to many factors. In order to ensure production capacity, there are many measures that will be taken, one of which is to extend the service life and reduce the failures in production, so as to ensure The balance of production capacity, which is no exception to the use of ultrafine mill, then in the process of maintenance and maintenance, what issues need attention?

Mining equipment is an indispensable and important equipment in today's construction and other projects. In the process of work, their production capacity is a problem that customers always pay attention to, but the production capacity is related to many factors. To ensure production capacity, it will be adopted. There are many measures, one of which is to extend the service life and reduce the failures in production, so as to ensure the balance of production capacity. This is no exception for the use of ultrafine mill, then in the process of maintenance and maintenance, it is necessary to pay attention to What are the problems?

Point, if the equipment work site is a high temperature environment, then the mill can be placed in a ventilated position, this can ensure that the motor work heat dissipation, which is an effective program to extend the service life of the motor.

Artificial sand production, can be divided into mechanisms of sand and broken marble grinder mechanism sand two categories. Rod mill mechanism sand with process stability, maturity characteristics. Crushing mechanism has vertical impact crusher sand sand and other types of rotating disk fragmentation laminated form , but the application of more PCL vertical shaft impact crusher.

Smaller than the marble grinder volume , basic simplicity , high efficiency, but the vertical impact crusher mechanism is not completely sand sand requires closed- loop circulation process large amount of finished sand fineness modulus compared large, coarse particles , and the particle size distribution is not ideal , especially in the production of limestone sand, grit and powder have produced more intermediate level of particles less than normal shortcomings.

This requires supplemented easy to control , stable quality marble grinder as a regulation. This can complement each other, that the impact of the joint use of vertical sand breaking technology combining with the marble grinder . In fact , finished by a vertical impact crusher sand is sand , sand and some mechanism marble grinder less than 5mm screen blanking, and most blended powder 4 made ​​, the composition of the particles of sand products more reasonable.

Duck Creek Pengshui hydropower male sand aggregate processing system uses three V1400 vertical impact with four broken marble grinder joint sand , finished sand production capacity of up to 370t / h.

In 2013 November, our company customer service team to use Baoji crusher shaker for nationwide customer feedback, focus on understanding the performance of crusher shaker in the production line, integrated the various aspects of the source of information, to evaluate the single sand line production and power consumption, benefit, the final result is Baoji play sand machine with four big advantage is the customer named sand artifact.

Next we analyze the crusher shaker in the development of the market in Baoji, Shaanxi concern customer sand industry prospects. The current development trend of city infrastructure in our country present comprehensive, housing construction, road construction, water conservancy project construction on the aggregate demand is very big.As Chinese civilization birthplace Shaanxi Baoji, has been vigorously promoting the construction of expressway.

In 2009 a comprehensive start the construction of the Yan Zhiwu expressway is carrying the Shaanxi people's dream project, known as the injected new vitality of the popular road become rich road development road. Baoji large play sand machine good reputation from Yan Zhi Wu Expressway to start. The above work every single equipment for 14 hours, each hour mechanism sand production reached 500 tons, has provided the powerful material guarantee for the construction of expressway.
