To turn the ore into sand, it needs to go through the steps of coarse crushing, medium crushing, fine crushing, and screening. The ore crusher is indispensable equipment in the production of sand. Due to the different physical properties and structural differences of ore raw materials, the selection of crushers should also be analyzed in detail. Although the crusher is divided into coarse crushing, medium crushing and fine crushing, in order to better subdivide the particle size and capacity of the finished material, various types of crushing equipment have been prepared accordingly. In daily production, we use the most crushers: jaw crusher, cone crusher, sand making machine, and impact crusher, hammer crusher, etc. There are many crushing equipment on the market. Choosing suitable crushing equipment can not only reduce the crushing time and reduce the waste of materials, but also help to a certain extent for the loss of the crushing equipment.
The output is also an important indicator that determines the selection of crushing equipment. The conventional understanding is that the higher the output requirement, the larger the size of the crushing equipment required, and the corresponding input and output will increase. With so many types of crushers, do you know the capacity of several common crushers?
1. Jaw Crusher
Feed size: ≤1360mm
Processing capacity: 50-1500t/h
Performance characteristics: The jaw crusher has a large feed size, which can be used for primary coarse crushing of raw materials; the integrated installation structure of the main machine and the motor is firm and reliable, and the footprint is small; the wedge-type discharge opening adjustment method realizes stepless adjustment, to reduce the labor intensity of workers and downtime; the large inclination angle bracket design makes the lower stroke of the cavity larger and higher output.
Feed size: <1000mm
Processing capacity: 50-1200t/h
Performance characteristics: used for crushing soft ore (dolomite, etc.), the finished product has good grain size and less powder. It is mostly used in small and medium stone factories, but cannot be used for sand making; the user can adjust the gap between the impact board and the hammer to control discharge granularity: New high wear-resistant materials are used in large quantities, and are equipped with a variety of safety locking devices to extend the service life, improve safety performance and save costs.
Feed size: ≤560mm
Processing capacity: 45-2176t/h
Performance characteristics: Cone crusher is mainly used to crush hard materials, and has large production capacity and high crushing efficiency. It is suitable for large stone factories; it has iron-pass protection and automatic cavity cleaning functions, which are stable and reliable; parts can be disassembled from the upper and side, which is convenient check and repair; the price is slightly expensive, but the use cycle is long, and the fully automatic control system can easily realize remote control.
Feed size: ≤1500mm
Processing capacity: 250-2000t/h
Performance characteristics: suitable for crushing limestone and medium-hard ore with compressive strength lower than 200Mpa; sledge hammer head, dual power, satisfying larger production capacity; one-time forming, no secondary crushing process, suitable for users with small working sites. At the same time, it reduces the purchase of other crushing equipment and saves investment costs.
Feed size: ≤240mm
Processing capacity: 8-715t/h
Performance characteristics: used in the fine crushing and shaping of minerals and rocks in a variety of metal and non-metal mines, refractory materials, abrasive ceramic raw materials, building materials, high-speed and high-speed railway construction, water conservancy and hydropower construction, civil sand and gravel aggregate production and other industries, especially for centering hard, extra-hard or abrasive materials, such as sandstone, granite, basalt, silicon carbide, emery, alumina, magnesia, etc. are more superior than other equipment. It has two crushing principles of "stone beat stone and stone beat iron", sharing a set of crushing chamber; equipped with hydraulic lifting opening device, manual or electric hoist, convenient for maintenance; equipped with PLC automatic control and monitoring system, high safety performance and convenient monitoring.
