Meanwhile, SBMwill stand on the unprecedented height, to research and develop more advancedkaolin ore milling equipment, grinding miller and other grinding machine, providingcustomers with the highest quality products and the most perfect service!
SBM ore milling equipment is the trend of today. The integrative serves is the main advantage of this equipment. The installation of this equipment has eliminates the complicated operation process and reduce the material and working hours consumption. The compact design has improved the flexibility of field presence. ore milling equipment can be used independently. According to the customer requirements and the type of materials in the production process, it can provide a more flexible process configuration to meet the various crushing and screening requirements of the user, which will made the transport more direct effective and the cost lower.
The disadvantages of ore milling equipments:
1. The increased broken reproduced link made the production line more complex.
2. The main parts are bringing from the foreign country. The domestic use experience is not enough. The supplier of the abrasion parts is difficult.
3. The operational stripping ratio is bad and the mining area is difficult.
4. The system links and overall reliability are bad, which limit the production capacity of this system.
The ore milling equipment that produced by SBM company can efficiently realize the recycle of the construction waster. It greatly promotes the recycle rate of the city rubbish. The disposed construction waster can be used for the production of regenerate construction material, which not only realize the recycle of the construction waster, but also reduce the power consumption and improve the production efficiency.
Recently, our company has introduced the world level designing and manufacturing technology for our single-cylinder ore milling equipment. Our new ore milling equipment has been welcome because of its various structural features.
The adjustment of the discharging mouth of the cone crusher can be completed through operating the control valve of the hydraulic system. If the iron is stuck in the discharging mouth, it can be removed by manipulating the hydraulic operating valve to control the movable cone to move up and down, thus reducing the labor strength and technical difficulty of the workers.
Our ore milling equipment can change the eccentric distance through changing the eccentric sleeve to adapt to the requirement of crushing different materials. Due to the adoption of hydraulic adjustment and hydraulic protection, complicated adjusting ring, supporting ring and spring device are eliminated, so that single-cylinder ore milling equipment has simplified structure and light weight.
There are bearings both above and under the principal axis, thus improving the force situation of the principal axis of the ore milling equipment which uses sealed chamber structure to prevent dust, so that it is more reliable than the water sealed structure of the spring cone crusher.
Since the principal axis of the movable cone uses simple supported beam structure, its eccentric angle is small, and generally speaking, the eccentric angle is only one second that of the spring cone crusher, for this reason, the crushing cone is relatively steep and the crusher is longer, thus improving the uniformity of the ore crushing.
The liner of the general cement ball mill is made of the manganese steel material whose service life is 6months to 12 months. According to the statistics, the national metal mine consumes 80,000 tons liner ore milling equipment. Recently, the experts of SBM have developed and researched a kind of magnetic liner which has surpassed a lot of advantages of the traditional liner. The working principles of the magnetic liner are the followings. Due to the magnetic field of the liner, when the mill works, it may absorb a layer of magnetic particles or the fragments in the grinding medium from the magnetic layer and form a protective layer so that the surface of the liner will not be worn directly. The magnetic liner instead of high-manganese steel liner will undoubtedly bring huge economic benefits to the enterprises. The magnetic liner can be widely used in the milling machine of the metal mine. Since the working principles of the magnetic liner are different from that of the common liner, the service life of the liner is far greater than the service life of the ordinary liner. The magnetic liner has the following advantages when it is used to deal with the magnetic materials in the ball mill.
The cement ball mill is mainly used for grinding the finished products in cement factory or the raw materials. The cement ball mill is also suitable for crushing various ore and other materials with grindability in metallurgy, chemical, electric power and other industrial and mining enterprises. The cement ball mill can be used for open stream grinding and the circle flow grinding composed by the powder concentrator. The cement ball mill has the characteristics of strong adaptability, continuous production and large crushing ratio. The cement ball mill can be used for both the dry production line and the wet production line. In addition, the grinding process and the drying process can be carried at the same time.
The cost of the liner can be reduced to 25% to 40%. The working surface of the magnetic liner can absorb a layer of magnetic material which can form a layer of protective layer so that the surface of the liner will not be directly worn. The magnetic liner reduces the time for replacement and maintenance and the working amount so that the operating efficiency is improved.

Crushing and grinding are mainly made by mineral processing equipment (jaw crusher) for coarse crushing. The standard cone crusher is used for crushing and crushing, and short head type cone crusher and roller crusher are adopted. Most of the medium and small-sized gold mining plants are broken by two sections and one closed circuit, and the large scale gold mining plant adopts three sections and one closed-circuit crushing process. In order to improve the yield and utilization coefficient of equipment, concentrator generally follow the principle of more crushing and less grinding, reduce the particle size of ore into the mill.
