Zhejiang mine crusher

1. Calculation method
1. Calculate I = Dmax / Dmax by the ratio of the maximum particle size of the material before crushing and the maximum particle size of the proct after crushing, where Dmax is the maximum particle size of the material before crushing; dmax― http://www.ysxuankuang.com/cpzx.html - the maximum particle size of the material after crushing
2. The ratio of the effective width of the feeding port and the width of the discharging port of the crusher
I = 0.85b/b
where
b --- the width of the feeding port of the crusher; B --- Crusher & lt; Width of discharge port
0.85 -
ensure the effective width of the crusher gripping the material. The maximum width of discharge port is selected for coarse crusher; Take the minimum width of discharge port for middle crusher
3. Calculate with average particle size
I = DCP / DCP
where
DCP - average diameter of material before crushing; DCP - average diameter of crushed material. The crushing ratio obtained by this method can truly reflect the crushing degree of sand and stone equipment.

2. The crushers used in quarries belong to stone crushers and mine crushers, including jaw crusher, heavy hammer impact crusher, impact crusher, cone crusher, plate hammer sand making machine, reversible sand making machine, vertical shaft sand making machine, grinding machine, etc. According to the crushing principle, it is divided into extrusion crusher and impact crusher. According to the particle size of crushing discharge, it is divided into coarse crusher, fine crusher and pulverizer. I'm a stone crusher manufacturer. I hope I can help you.

3. Jiapurui specializes in the proction of crushers. At present, the mining crushers proced by jiapurui mainly include hammer crusher, deep cavity fine jaw crusher, impact crusher, European version hammer crusher, cone crusher, Simmons cone crusher, hydraulic cone crusher, PCL impact crusher, VSI series impact crusher and diesel power crusher.

4.

Lithotriptor can be divided into medical lithotriptor and mining lithotriptor. In principle, the mining crusher is suitable for crushing massive hard rock in mines. The typical granite discharge particle size is less than or equal to 40mm, accounting for 90%. The machine can handle materials with side length less than 100-500mm

mine crusher is mainly used to crush all kinds of stone materials. According to different crushing principles and proct particle size, it can be divided into many models. Crushers are widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical instry. Objective: in the metallurgical, mining, chemical, cement and other instrial sectors, a large number of raw materials and recycled waste need to be processed by crusher every year. For example, in the concentrator, in order to separate the useful minerals in the ore, it is necessary to use the crusher to crush the raw ore to the size required by the grinding process. The crushing machine is needed to crush the raw material to the size required by the next operation. In coking plant, sintering plant, ceramic plant, glass instry, powder metallurgy and other departments, it is necessary to use crushing machinery to crush raw materials to the size required by the next operation. Significance: in the chemical instry and electric power sector, crushing and grinding machinery will crush and grind raw materials, increase the surface area of materials, and create favorable conditions for shortening the chemical reaction time of materials. With the rapid development of instry and the rapid rection of resources, it is very important to reuse the waste in the proction of various departments. The reprocessing of these waste needs crushing machinery. Therefore, crushing machinery plays an important role in many departments. Mining crusher, also known as crusher, is a crushing machine whose particle size is more than 3mm in the discharge, accounting for more than 50% of the total discharge. The proction cost is low. Compared with the hammer crusher, the wear-resistant parts have the advantages of long service time, high proction efficiency and small investment

5. Small ore crusher is not very high for crushing output. Generally, the output is about 3-5 tons, 10-50 tons, and the price ranges from 8000 to more than 100000
mainly depends on the configuration and model
for reference only

6. The price of iron ore crusher mainly depends on the output. Different output requires different equipment. Cheap equipment is about 0.5 tons an hour, and expensive equipment is hundreds of thousands an hour.

7. Giant rock crusher is the representative of large stone crushing in crusher, which can crush the stone with diameter of more than 800mm, such as large ore, marble leftover, curb stone, large aerated brick waste, construction waste concrete block. It is the most popular large rock crusher in the market at present
in the long-term communication with customers, Zhengzhou General Mining Machinery Co., Ltd. has keenly felt that many stone proction lines and sand proction lines now use jaw crusher because of the large raw material of stone, so it upgrades and improves the technology in time, and introces giant stone crusher and giant stone crusher to the market, It can process large stones
with a diameter of less than 2 meters for free installation and debugging.

8. For small stone crushers, the output of about 3 tons is about 5000 yuan, and the output of about 15 tons is about 15000 yuan. It is suggested that you determine the model of the machine according to your actual demand, and the price is better.

9. Zhejiang Shuangjin has high requirements for parts, good mechanical rability and low repair rate. Their jaw crushers are not bad, and their output is very good. Our excavators and pickaxes are not good enough at the beginning. Our mine makes machine-made sand. In Shuangjin's full set of sand making proction line, the cone type sand making machine seems to be their patented proct, which is much higher than our previous machine output. Now our machine-made sand output is the largest in the province.

10. The single-stage jaw crusher is the exclusive patent proct of Yiwu black and white Mining Machinery Co., Ltd., which has the unique effects of energy saving, consumption rection and proction increase, as follows:
1. The single-stage jaw crusher eliminates the inherent disadvantages of the traditional jaw crusher mechanical structure of "force recing state", and changes it into "force increasing effect", It makes the mechanical structure of jaw crusher more scientific and reasonable
2. It realizes "one machine two-stage crushing" and even "one machine three-stage crushing", which can directly crush large materials below 500 mm into sand or powder below 5 mm at one time, which is the first time for jaw crusher to realize "fine crushing" (sand making) function
3. It is easy to use and maintain with "rough breaking" equipment, which reces the technical requirements for on-site maintenance and operation personnel, and is easy to employ or train
4. Greatly simplify crushing proction line, save investment (omit secondary and tertiary crushers and conveyors), save land, save energy and consumption, and easy to manage. It not only promotes the technical progress of "crusher", but also promotes the technical progress of "crushing proction line".
