The choice of jaw crusher depends primarily on the feed material size and the amount to be crushed.With its compact space-saving design, Model BB 51 is often used in laboratories for pre-crushing small amounts of sample with a large feed size.Series BB 100, BB 200 and BB 300 jaw crushers are mainly used for pre-crushing hard, brittle products with a degree of hardness >3 on the Mohs’ scale.BB 100 and BB 200 are particularly suitable for standard size reductions,e.g. of minerals, ores and fossil fuels.Models BB 200 and BB 300 are also suitable for size reduction in process plant, e.g. when included in a sampling station.
A Jaws crusher consist of two plates one job being fixed and other being mount by pitman mechanism due which the crushing can be done in one stroke due small moment of jaw plates. these two plates form a taper chute so that material can be crushed, as the load acts on the plates its wearing rate is high hence high wear resistant material is used generally magnese still are used a heavy flywheel is use to crushed the tough materials which provides the required inertia. Double Toggle jaw crushers may feature hydraulic toggle adjusting mechanisms.
XSM jaw crushers are used for the rapid, gentle crushing and pre-crushing of medium-hard, hard, brittle and tough materials. The variety of materials offered, such as heavy-metal free steel, their efficiency and safety make them ideal for sample preparation in laboratories and industrial plants.The throughput and final fineness depend on the type of instrument, the gap width and the crushing properties of the sample.Jaw crushers are particularly suitable for the preparation of rocks, minerals, ores, glass, ceramics, construction materials, brittle metal alloys, slag, synthetic resins and many other hard, brittle substances.
This project is located in the Malay nicaea, mobile crushing mainly for the production of architectural sand aggregate screening system, the project by my company with Singapore T joint implementation process design, equipment manufacture, system installation and debugging, the system training delivery operation, this project because of considering the customer's periodic construction, at the same time in order to improve the efficiency of system installation, saving the cost of investment, the system is broken unit and screening unit adopts the tyre mobile solutions.Because the material source of the project is coarse aggregate produced by the original mine jaw broken by the customer, the project is designed with two-stage crushing and screening sections of medium and fine crushed cone, and equipped with vehicle-mounted container centralized control room.
Customer demand: 200 tons per hour
Components: vibration feeder, jaw crusher, impact crusher, circular vibrating screen, belt conveyor and other related equipment.
Introduction to Dolomite
Dolomite crystal belongs to carbonate mineral of trigonal series, including iron dolomite and manganese dolomite. Its crystal structure is like calcite, and is usually rhombohedral.Dolomite is mainly composed of calcium carbonate and magnesium carbonate. This stone appears to be very close to limestone in appearance. In fact, dolomite is often found in areas where limestone deposits are found.Dolomite can be widely used in building materials, ceramics, glass and refractories, chemical industry and agriculture, environmental protection, energy conservation and other fields.Moreover, the production of Dolomite ore in China is very large, which can not only meet the needs of relevant industrial production, but also has been exported abroad, and shows a good development trend.
