How to Control the Amount of Steel Balls in the Construction Waste Crusher?

Construction waste crusher is the key equipment for materials to be smashed after crushing, which is widely used in cement, silicate products, new construction materials, refractory, chemical fertilizer, black and non-ferrous metals, glass chinaware and other production industries. It can conduct dry or wet grinding for many kinds of ores and other materials which can be grinded. As the construction waste crusher can produce materials with high fineness, low energy consumption and low production cost, so the construction waste crusher is more and more widely applied in ore dressing industry. However, how to make it more efficient? It is not as simple to implement, for example the efficiency of construction waste crusher itself, the quality is the root. On the other hand, whether the installation work is rigorous, or the operator is responsible. All of these factors mentioned above have necessary connections, and during the following paragraph, we mainly introduce the relationship between steel ball amount and motor current of construction waste crusher. The steel balls will cause certain wear in the operation process, some customers will reduce the use of steel balls, so as to reduce the losses. However, in general, the flow of current and the amount of steel balls is directly proportional, you should not decrease the number of balls in order to increase the yield and reduce the losses. The number of balls, the motor flow as well as the fineness and amount of materials can influence each other. In the selection of steel balls, you should also take the characteristics of raw material into consideration, if the hardness of the material is relatively large, choose the relatively large balls in the range of size that construction waste crusher can bear. SHR Machinery is a professional manufacturer of construction waste crusher, and we produce various types of construction waste crusher, such as cone construction waste crusher, chinaware construction waste crusher, energy saving construction waste crusher, etc. SHR construction waste crusher has reliable performance, reasonable price and considerate after-sales services. We will spare no effort to find a perfect way for customers in our future researches!

How to Choose Crushing Equipment for the Stone Production Line

In the stone production line, crushers are the indispensable equipment and also the important material crushing machines. Then how can the customers choose stone crushing equipment in a more proper way? Next, we will analyze it from the following three aspects: (1) Features of the raw materials: The hardness, granular composition, mud content and water content are very important parameters. For this reason, for different raw materials, the customers should choosing different crushing and screening machines. When the raw materials are very hard, generally speaking, jaw crusher and cone crusher are often used as primary crushers; and when the raw materials are not very hard, the customers can choose impact crusher as primary crusher. The granular composition of the raw materials also influences the general parameters. As for the rocks produced by exploding in the quarry yard, the customers should choose construction waste crusher according to the biggest granularity of the rocks; as for sand-cobble raw materials, the selection of primary crusher should be based on grading curve and the pre-screening machines should be equipped; when the mud and water content of the raw materials is high, wet crushing and screening flow should be considered. In general, the customers should choose the technological flow of the equipment and the production capacity of all parts according to the product granularity and choose the types of primary and secondary crushing equipment according to the hardness of the raw materials. (2) Quality requirement of the products. The product quality includes granularity, product grading and the shape of the particles. As for different projects, the quality requirements for the final products are also different and the processing quality of the products is related to the crushing machines and the production flow. If the product granularity is small, the general crushing ratio of the crushing and screening equipment will be high, and the more the product fraction, the more complicated the equipment will be. Sometimes in order to obtain rocks with multiple grading, an independent screening machine can be equipped for grading. In many projects, the dust content of the stone materials should not be high since the dust will influence the quality of the concrete. If the dust content exceeds the required standard, a cleaning procedure should be added. (3) Production capacity. The production capacity is an important technological parameter for the crushing and screening machines. The production capacity requirement includes two aspects: the productivity of the granularity standard product and the productivity of all the products. As for the project practice, the productivity of every granularity standard product has more significance. For this reason, when determining the production capacity of the equipment, the customers should first consider the actual needs of the projects.

Advantages of Dry Type Construction Waste Crusher Technology

The rapid development of China's iron and steel industry makes the iron oredemand also grow, so a lot of lean ores whose grade lower than the average levelare mined and used, which leading to the increase of processing cost. Dry typeconstruction waste crusher technology can save energy and reduce the processingcost. construction waste crusher operation is normally taken in the mines, and itspurpose is to throw the tailings and improve the ore grade. Dry-construction waste crushertechnology has five advantages: ①Reduce transportation costs of theore; ②Improve the grade of crude, reduce wet-selectioncosts; ③Beneficiation medium is air without greater requirement of workingconditions; it is much better used in water-scarce areas; ④Tailings aredirectly discharged into the mine, and do not need to build a tailings pond. Inaddition, the tailings after simple treatment can be used for farmlandafforestation without environmental pollution; ⑤Most of the soil and mud arejettisoned with tailings in dry election, more favorable to subsequentsorting. In the beneficiation flow, dry-type construction waste crusher can be divided intopre-crushing pre-selection and pre-milling construction waste crusher. Pre-crushingpre-selection refers to the selection before secondary crushing and three-stagecrushing. It throws away non-magnetic minerals and barren rock that produced inthe last crushing process, greatly reducing consumption and pressure of thefollowing crushing. Pre-milling construction waste crusher refers to the selection betweenfine crushing process and grinding process. After crushing, magnetite materialand gangue are further separated, dry separation then can vastly improveconcentrate grade so that improve ore taste and reduce grinding quantity. Thedry type construction waste crusher has significantly obvious effect; it can greatly improveresource utilization, reduce processing cost, and has been popularized bycrushingmachine productionenterprises.
