It includes building materials such as electrical wiring, waste bricks, cements, rebar, insulation and nails, meanwhile it also involves dredging materials, tree stumps and rubber. Besides it still contain asbestos, lead, or other harmful materials.In general, the construction waste consists of the construction-related waste materials, demolition debris, land clearing debris, and landfill disposal. Specifically speaking, construction waste is composed of unwanted materials generated directly or passingly by the building demolition waste , construction waste or industries. Zenith can provide the debris recycling plant and equipment in India.
Our sorters can treat such ores in a dry process in size ranges of -300/+20mm and feed rates of up to 300t/h. Nonetheless, certain deposits require physical processing of the ore to reach grades high enough to render transport economical.Manganese ore is typically mined in huge volumes and only crushed and screened before it is exported.
Dolomite can be used as rholite for making basic refractory and blast furnace iron. It can also be used as the ingredient to make glass and ceramics. All in all, dolomite is widely used in building materials, ceramics, glass and fireproof, chemical, agriculture, environment protection and energy saving fields and so on.
During the crushing stage, jaw crusher and cone crusher are two common types of crushing machine. Typically, cone crushers are suitable to crush various kinds of ores and rocks with medium or above medium hardness. Several stages of crushing and screening of mineral are employed to produce the final product. Usually, jaw crushers are used in the primary crushing stage, and cone crushers are used in the secondary crushing stages. However, there are other difference between jaw crusher and cone crusher, such as the working principle, price, working time, and working conditions, etc. Jaw crushers are used to deal with stones and ores with high hardness. To protect crushing machines and ensure the crushing efficiency, jaw crushers and cone crushers are always combined together. Compared with jaw crusher, cone crusher often adopts the spring safety system which acts as an overloading protection system that allows metals to pass through the crushing chamber so as not to damage the cone crusher.Answer: Hard rocks in the quarry must be crushed several times before it is at a size that is suitable for use by industry. If you need further information on jaw crusher vs cone crusher, you can contact our online mining engineers, who will offer more professional suggestions for you. The two types of crusher are widely applied in the metallurgical, construction, road building, chemical and phosphatic industry.
For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which a preferred embodiment of the invention is illustrated.The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
Concentrates were then collected at 2, 6, 12 and 20 min of flotation and a tailings sample was taken after the collection of the last concentrate. The cell was then topped up with the particular water quality to the 250 mL mark. Through a microsyringe, air was introduced at the base of the cell at a flow rate of 7 mL/min. The concentrates and tailings were filtered, dried and weighed. 50 mL of the particular water quality (adjusted for pH 9 using very dilute stock solutions of either NaOH and or HCl) was added to the mineral sample; the mixture was then ultra-sonicated for 5 min to allow for good dispersion of the mineral mixture. The procedure was repeated for the various water qualities, and all runs were done in duplicate to minimise experimental error. 90 µL (300 g/t) of 1% CMC solution was then added to the cell and conditioned for 1 min.Microflotation tests were performed using 3 g of talc at a size fraction of +38–106 µm. The suspension was then transferred to the microflotation cell, and the pulp was circulated by a peristaltic pump set at 90 rpm.
