SCM series superfine grinding mill is a new type superfine powder (325-2500 mesh) processing equipment developed through accumulating years of grinding mill production experience, absorbing Swedish advanced machine manufacturing technology, and undergoing tests and improvements of many years. The SCM grinding mill is the result of Chinese and Swedish advanced technologies, and is the latest product leading the world trend of powder grinding mill.

Newly Designed Grinding Curves Newly designed grinding curves of grinding roller and grinding ring further enhance the grinding efficiency. With the same fineness and power, the production capacity is 40% higher than that of jet grinding mill and stirred grinding mill, and the yield is twice as large as that of ball grinding mill. However, the system energy consumption is only 30% of the jet grinding mill. Cage-type Separator---Adjustable Fineness between 325-2500meshes Cage-type separator produced with German technology is adopted to effectively increase the powder separating precision. In addition, multi-head cage-type separator can be configured according to the users' requirements on yield, fineness and sieving rate. The product fineness can be adjusted between 325-2500 meshes, and can achieve d975m once. No Rolling Bearing & Screw in Grinding Chamber The grinding chamber has no rolling bearing and screw inside, so that users are free from worries about damages on bearing or its sealing parts, and there is no machine damage problem caused by loose screws. The lubricating device is installed outside of the main shaft, so that lubrication without shutdown can be realized externally, and the production can be continued for 24h. Pulse Dust Removal High-efficiency pulse dust collector is adopted, so no dust pollution generates during the operating process of the entire grinding mill system. Silencer and noise elimination room are configured to reduce noises. The production is organized fully according to the national environmental protection standards.

home - delta grinding facility

home - delta grinding facility

Lehigh Hanson Materials Limited (Lehigh), is proposing to construct, operate and decommission a grinding facility with a marine terminal (the Project) to manufacture Supplementary Cementitious Material (SCM). The Project includes the construction of a grinding facility and associated dust-collection equipment, raw-material stockpiles, storage silos, pneumatic piping connecting to the cement plant, and a covered conveyor leading to a newly constructed vessel berth. The Facility, once fully operational, is expected to have an average annual production capacity of 650,000 t and employ approximately 14 people. The Project will be located adjacent to the existing Tilbury Island cement plant, on lands owned by Lehigh that are zoned for industrial use. The project address is 7753 Berg Road, Tilbury Island, in Delta, British Columbia.

Lehigh is a division of the Heidelberg Cement Group (Heidelberg) one of the worlds largest building material companies, with about 60,000 employees at more than 3,000 production sites in 60 countries across the globe. Heidelberg acquired its Canadian operations in 1993, and currently maintains four cement plants in Canada, including the Tilbury Island cement plant, along with extensive aggregate deposits and many ready-mix concrete plants.

The Project is proposed to be located along the Fraser River, on Tilbury Island, Delta, BC. and will cover an area of approximately 8.5 ha (7.9 ha of terrestrial area and 0.6 ha of aquatic habitat). The location was selected as it is adjacent to, and can make use of, existing infrastructure owned and operated by Lehigh, including the existing vessel berth that will be used during initial Stage 1 operations. Tilbury Island is a highly developed industrial area, with approximately 80% of the land used for industrial activities, including the existing Lehigh cement plant, the FortisBC Tilbury LNG Plant, Dynacor Coatings Ltd., and several manufacturing and retail businesses, including those in the Tilbury Island Industrial Park that is nearing full build-out.

Supplementary Cementitious Materials replace cement in concrete and are made from by-products (slag, silica fumes, fly ash) that originate from steel mills, blast furnaces, and coal-fired power generation plants. Re-using these materials has the benefit of improving the hardness, durability, and porosity of concrete, while also reducing the volume of greenhouse gases associated with the production of cement by up to 40%. With greater demand for green-building projects certified by Leadership in Energy and Environmental Design (LEED) and changing building codes, SCMs will become critical for the continued sustainable use of concrete.

To create the Supplementary Cementitious Material, Lehigh is proposing to import and store Ground Granulated Blast Furnace Slag (GGBFS), a by-product of the iron and steel industry, which will be ground to suitable fineness and mixed with cement to produce slag cement.

Stage 1 will entail construction and commissioning of the grinding facility and associated infrastructure. Materials will be shipped through the existing marine terminal at the adjoining Delta Cement Plant. Preliminary design for Stage 1 is expected to be completed to support the required environmental assessment process. Stage 1 is expected to be complete in 15 months excluding pre-construction and site preparation

Stage 2 will entail construction and commissioning of the marine terminal and conveyor belt system, and is expected to be complete in 16 to 22 months, excluding pre-construction and site preparation, depending on the chosen configuration. The design for Stage 2 will remain conceptual, and the timing of construction is dependent on market conditions.

At this time, the Delta Grinding Facility is in the early stages of project development. The Project is subject to review under both the BC Environmental Assessment Act and the Canadian Environmental Assessment Act, 2012. The Project is undergoing a provincial and federal environmental assessment through a substituted process led by the BC Environmental Assessment Office. The BC Environmental Assessment Office will conduct a single assessment that the Government of Canada and the Government of British Columbia will rely upon to make their respective decisions on whether the Project should proceed.

The Project entered the environmental assessment process with the issuance of the Section 10 order by the BC Environmental Assessment Office on March 14, 2019. The Canadian Environmental Assessment Agency, now the Impact Assessment Agency of Canada, commenced the environmental assessment on May 7, 2019. On August 13, 2019 the Impact Assessment Agency of Canada notified Lehigh that they are grandfathered under the Canadian Environmental Assessment Act 2012, and that under provisions of the federal Impact Assessment Act the substituted environmental assessment process for the Project will continue under the requirements of Canadian Environmental Assessment Act, 2012, and the BC Environmental Assessment Office will continue to conduct the substituted environmental assessment process.

The Project is in the pre-application stage of the environmental assessment process. The purpose of the pre-application stage is to establish the scope and the terms of reference for the BC Environmental Assessment Office process and to ensure that both the BC Environmental Assessment Office and the Impact Assessment Agency of Canada have all the information they need to conduct a complete and thorough assessment of the Project. The pre-application phase provides input opportunities for Indigenous Nations, government agencies and the general public.

We are interested in hearing your thoughts on the proposed Delta Grinding Facility and we appreciate and welcome your perspective and feedback! If you have any questions or comments related to the Delta Grinding Facility, please fill in the form below to contact our representative.

natural pozzolan use in the us - cement industry news from global cement

natural pozzolan use in the us - cement industry news from global cement

Charah Solutions has been steadily building up its fly ash distribution business in recent years with an eye on the supplementary cementitious materials (SCM) market. This week it opened the third of its new series of SCM grinding plants, at Oxnard in California, US. The unit sticks out because it is focusing on grinding natural pozzolans. The plant will receive natural pozzolan by truck and rail and then use Charahs patented grinding technology to produce pozzolan marketed under its MultiPozz brand. The previous plants in this series mentioned natural pozzolans but this is the first to promote it explicitly.

The change is potentially telling because global demand for granulated blast furnace slag (GBFS) outstrips supply. Both performance benefits and environmental regulations are pushing this. Its a similar situation for fly ash, also driven by trends to close coal-fired power stations in some countries. As Charles Zeynel of SCM trading firm ZAG International explained in the March 2019 issue of Global Cement Magazine, ...volcanic pozzolans are a potential SCM of the future. This is gaining traction, but its slow progress at the moment. This will be the answer for some users in some locations.

The problem though is that natural pozzolans are down the list of preferred SCMs for their chemical properties after silica fume, GBFS and fly ash. The first is expensive but the latter two were traditionally cheap and easy to obtain if a cement or concrete producer had access to a source or a distribution network. Natural pozzolans are very much subject to variations in availability.

Its no surprise then that Charah is promoting natural pozzolans in a Californian plant given that states environmental stance. Its unclear where Charah is sourcing their pozzolan from but they are not the only company thinking about this in the US. Sunrise Resources, for example, is working on the environmental permits for a natural pozzolan mine near Tonopah in Nevada. As it described in its company presentation, California and Nevada are the most affected states in the fly ash supply crisis because they are, ...at the end of the line when it comes to rail deliveries from power stations in central and eastern USA. It also estimated that California used 0.9Mt of pozzolan in its cement production of which about 90% is fly ash. The state produced 9.6Mt in 2015. Other companies are also mining and distributing natural pozzolans in the US as the website for the National Pozzolan Association (NPA) lists. Although, if this line-up is comprehensive, then the field is still fairly select. Most of these companies are based in the west of the country.

One last thing to consider is that various groups are tackling a potential future lack of SCMs for the cement industry by making their own pozzolanic materials through the use of calcined clay. These groups include the Swiss-government backed LC3 project and Cementirs Futurecem products. Using clay should bypass the supply issues with natural pozzolans but the cost of calcining it requires at the very least an investment to get started.

As concrete enthusiasts often point out, a variant of pozzolanic concrete was used by the Romans to build many of their iconic structures, some of which survive to the present day. To give the last word to the NPA, What is old is new again: natural pozzolan is back! If environmental trends continue and steel and coal plants continue to be shut then it might just be right.

scm ultrafine mill create benefits for plaster grinding plant in japan

scm ultrafine mill create benefits for plaster grinding plant in japan

As a potentially non mineral resource rich and good technological material prosperity, plaster has attracted people's attention. It especially has the excellent characteristics: simple process, low energy consumption, light quality, quick setting, so that the developed countries carry out a lot of work from theory to application. Japan, Germany, France, Russia and other industrial developed countries have been attached great importance to study the by-product plaster utilization over the yearsthey took advantage of phosphogypsum and flue gas desulfurization plaster and successfully opened up many new applications and new technology about plastering.

Japanese natural plaster resources are very limited and the quality is poor, industrial by-product plaster line use has been confirmed early; they began to use phosphogypsum for plaster board production in the early 20th century. In 1986, Japan consumed 6800000 tons plaster; In 1998 Japan plaster total production is 305000000 square meters. Subsequently, Japan specified the plasterboard used as fireproof board for ceiling and interior wall, resulting in plasterboard demand greatly increased. Japanese timber resources are limited; plaster products have broad application market in order to meet the needs of the construction industry. Wood building structure of Japan housing is a very obvious characteristics, plasterboard used as interior decoration materials has a rapid demand growth and obtained a widespread promotion.

Plaster is monoclinic mineral, whose main chemical components are calcium sulfate (CaSO4). Plaster has a wide range in the industrial materials and building materials which can be used in the cement retarder, plaster building products, model making, medical food additives, sulphuric acid production. Plaster began its formation on Earth 600 million years ago. Before that, sea levels were much higher than they are today. As climate changed and sea levels lowered, sea water on what is now dry land evaporated, leaving plaster deposits behind. Today, processed plaster, or hydrous calcium sulfate has made outstanding contribution to the Japanese construction industry.

In Japanese plaster grinding plant, drying, grinding, and calcining process are performed in heated impact milling equipment. In these mills hot gas contacts plaster as it is ground. The gas dries and calcines the ore and then conveys the stucco to a product cyclone for collection. The use of heated impact mills eliminates the need for rotary dryers, calciners, and roller mills. Plaster grinding plant process in Japan main purpose is to get gypsum powder whose fineness less than 6mm, the grinding effect is helpful for the fabrication of Japan gypsum products.

We must say a fact that SCM Ultrafine Mill has an excellent performance in Japanese plaster grinding plant based on its unique characteristics. SBM milling equipment is mainly used to produce fine powder and super fine powder. SCM Ultrafine Mill is applicable to non-flammable and non-explosive materials with hardness less than 6mm, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, talc, vermiculite, diatomite, barite, gypsum, alum earth, graphite, fluorite, and potash ore.
