The diabase artificial aggregate crushing production and processing plant

Diabase is usually found in smaller relatively shallow intrusive bodies such as dikes and sills. Diabase dikes occur in regions of crustal extension and often occur in dike swarms of hundreds of individual dikes or sills radiating from a single volcanic center.

The Palisades Sill which makes up the New Jersey Palisades on the Hudson River, near New York City, is an example of a diabase sill. The dike complexes of the British Tertiary Volcanic Province which includes Skye, Rum, Mull, and Arran of western Scotland, the Slieve Gullion region of Ireland, and extends across northern England contains many examples of diabase dike swarms. Parts of the Deccan Traps of India, formed at the end of the Cretaceous also includes dolerite. It is also abundant in large parts of Curaçao, an island off the coast of Venezuela.

In Western Australia a 200 km long dolerite dike, the Norseman–Wiluna Belt is associated with the non-alluvial gold mining area between Norseman and Kalgoolie, which includes the largest gold mine in Australia, the Super Pit gold mine. West of the Norseman–Wiluna Belt is the Yalgoo–Singleton Belt, where complex dolerite dike swarms obscure the volcaniclastic sediments.

Baise Multipurpose dam is located the Youjiang upstream Baise river, is the one mainly in flood control, combined with the overall efficiency of power generation, shipping, both irrigation and water supply (a) large water conservancy and hydropower project of 130 m high roller compacted concrete gravity damthe total amount of concrete about 3 million m3 (of which RCC 2.2 million m3), 4.1 million m3 of concrete aggregates. The dam area to the lack of natural aggregate reserves and quality of artificial limestone aggregate is not ideal, the preliminary design phase of the project, began to study application of the main dam right abutment abundant diabase feasibility of artificial aggregate. The diabase artificial aggregate in the concrete application of domestic and foreign precedent, the need to study and solve the first problem is the fragmentation problem. Diabase is a hard rock processing equipment of artificial limestone aggregate, Guangxi region, can not be the diabase processed into the design of concrete aggregate.

Diabase rock hard, uniaxial compressive strength of 120 ~ 200 MPa, which is limestone 2 - 4 times. Diabase stone excavation of diversion tunnel of Baise Multipurpose dam, transported to the Guangxi region of leafy Hydropower Station, Rock Ertan Hydropower Station site. Artificial limestone aggregate processing system, the crushing test, the result is a large energy consumption, the rate of consumption of steel, the high cost of crushing, and crushing the aggregate gradation to meet the design requirements. Through research that, Fujian Mianhuatan Hydropower Project in roller compacted concrete dam is artificial granite aggregate, the uniaxial compressive strength of granite, limestone, 1 to 2 times. The engineering of artificial granite aggregate crushing production system are examined, and its energy consumption, the consumption of steel ratio and crushing costs and the Guangxi region of limestone aggregate is not very different, and aggregate gradation. To this end, the researchers again Baise Multipurpose dam diversion tunnel excavation of diabase stone, transported to the Fujian Mianhuatan Hydropower Station site, crushing granite aggregate production systems, diabase aggregate crushing test.

From diabase artificial crushing the whole process to see Mianhuatan Hydropower Project artificial aggregate system of diabase can be processed into line with the artificial aggregate of the design requirements, at all levels of crushing equipment production capacity to achieve the required quota. On laboratory test can be broken index, abrasion index and the crushing test namely diabase power index larger than granite, crushing energy consumption diabase than granite. Grindability index diabase than granite diabase crusher wear body than granite.

From the test results, levels of coarse aggregate grain better, less flakiness content, finished level with a reasonable distribution of ultra-Thomson diameter can be controlled in the range specification allows; Barmac crushing machine production of the diabaseshape better, artificial sand fineness modulus in line with regulatory requirements and the gradation.

The diabase artificial gravel powder high, and the powder with water easy to agglomerate or stick wrapped in the aggregate surface, all dry crushing process should be adopted and strictly control the water content of the source material.

Using Swedish SvEDAI. The early pieces A company JMl211HD jaw crusher, the s4000C gyratory crusher secondary crushing, crushing machine three crushing and the B9000 Barmac crushing Sand H4000MC cone, can be produced to meet the design or specification of the requirements of artificial diabase aggregate.
