Can Paper Mill Sludge Be Added to Concrete Mix?

Paper mill sludge is a byproduct of the papermaking process and is primarily composed of cellulose fibers, calcium carbonate, and other inorganic compounds, like limestone. Existing asphalt concrete mineral powder is mostly made from limestone. This method consumes a large amount of limestone. So, can paper mill sludge be added to concrete?

Can coal gangue powder replace fly ash?

Can coal gangue powder replace fly ash? What equipment is used to prepare gangue fly ash? Fly ash was originally a solid waste that no one cares about, but in the past 40 years of waste utilization practice, it has been increasingly used in the field of building materials. For example, fly ash (silicate) cement is a hydraulic The cementitious material is made of Portland cement clinker, fly ash and appropriate amount of gypsum. Coal gangue has similar chemical compositions to fly ash and clay, and the latter two are excellent building materials. Today, coal gangue vertical mill manufacturer Guilin Hongcheng will analyze and answer for you.

Methods for Regenerating Spent Activated Carbon

With the massive amounts of spent activated carbon resulting from pollutant adsorption, it has become a significant industrial solid waste. Direct incineration of spent activated carbon can release various hidden bacteria and viruses into the air, posing potential health threats to humans. Discarding it leads to soil and water pollution as well as wastage of resources. So, how can spent activated carbon be handled?

Can mineral powder be made into waterproof material?

Can mineral powder be made into waterproof material? Yes, there are many raw materials involved in waterproofing membranes, and a large part of them are non-metallic minerals, such as pink quartz, heavy calcium powder, and wollastonite used in preparing waterproofing agents. These non-metallic minerals need to be ground before they can be mixed and used. So, how to produce mineral powder for waterproof membrane? As a manufacturer of ore powder mills, Guilin Hongcheng will answer this question for you today.

What is the principle of limestone grinding?

What is the principle of limestone grinding? Limestone is fired into lime blocks. In order to make lime powder, it needs to be finely ground. During fine grinding, a limestone Raymond mill, which is a limestone grinding machine, is needed. As a manufacturer of limestone Raymond mill, Guilin Hongcheng will introduce to you the working principle of limestone grinding machine today.

How to use sludge incineration ash?

How to use sludge incineration ash? As a "derivative" of sewage treatment, sludge production continues to increase as the amount of sewage treatment increases. At present, the sludge incineration treatment process can achieve harmlessness, reduction, energy recovery, etc. to the greatest extent, and has become one of the mainstream technologies for sludge treatment and disposal. Incineration ash is both polluting and has certain resource characteristics. As a solid waste vertical grinding mill manufacturer, today Guilin Hongcheng will introduce to you the comprehensive utilization of sludge incineration ash.

How to judge calcite quality
