What kinds of equipment are suitable for small-scale domestic waste disposal?

At present, there are three types of small-scale domestic refuse organic combustible waste treatment furnaces, including mechanical grate, rotary kiln retorting and pyrolysis gasifier. 1 .mechanical grate incinerator The mechanical grate incinerator uses layered combustion technology, which has the advantages of low requirement for garbage pretreatment, wide adaptability to garbage calorific value and simple operation […]

Brief Introduction of Heavy Calcium Technology and Equipment Technical Performance

Ⅰ.Raymond Mill+Classifier Technology Raymond mill is a kind of crushing, which uses motor to drive the roller and centrifugal force to press the materials under low-speed conditions. It is accompanied by intermittent impact crushing. Raymond Mill has great advantages in terms of investment and energy consumption in the production of products below 400 mesh. However, […]

The Signification of temperature between Preheating Time and Calcination Time in Activated Lime Production

In order to promote the development of active lime technology and provide good service, through long-term sampling experiments, a large number of practical production process control data were finally obtained, including the research of limestone calcination active lime preheating, calcination optimum time, calcination optimum temperature and other levels of diversification.   According to the experimental […]

Perfect Performance of Cement Rotary Kiln Co-processing Waste Treatment

The global cement industry is pursuing the harmonious coexistence of environmental protection and cement production. Using cement rotary kiln to treat municipal solid waste synergistically has always been the common goal of the industry to achieve the ultimate reuse of waste resources. In the process of industrialization and urbanization in China, in order to meet […]

Indonesia oil sand pyrolysis characteristics

Oil sands are sedimentary sands rich in natural bitumen and are therefore also referred to as “asphalt sands”. China’s energy structure is rich in coal, lean in oil, and low in gas. Oil sands are unconventional oil and gas resources. The reserves are second only to coal. After oil sands are dry distillation, pyrolysis oil […]

Ⅰ.Market Demand Situation As an energy-saving, green and environmentally friendly mineral filler, heavy calcium is mainly consumed in paper making, plastics, rubber, paint and coatings. Paper and plastics industry is the main industry for large-scale demand and fine application of heavy calcium. The consumption of heavy calcium in the world paper industry has increased from […]

Method for treating oil sludge with different oil content

What is oil sludge? Oil sludge refers to oily solid waste generated during oil extraction, transportation, refining and oily wastewater treatment. The oil sludge generally has an oil content of 10-50% and a water content of 40-90%. In China’s petrochemical industry, an average of 800,000 tons of tank bottom mud and pool bottom mud are […]

Grinding process of cement and particle grading and water demand

The water demand of cement has already attracted the attention of cement users. Especially in the areas where commercial concrete is developed, more and more users are placing higher and higher requirements on the water demand of cement. Concrete producers are hoping to choose cements that require less water, which affects the competitiveness and price […]
