1. Single flotation process The principle of mineral processing is based on the difference in chemical properties of wollastonite and calcite minerals, directly through flotation machine, flotation agent , etc., through flotation machine to separate them from each other to obtain wollastonite concentrate. 2. Positive flotation process: Positive flotation, also known as preferential flotation, is to adjust the surface electrical properties of wollastonite and calcite to make the wollastonite with a different potential, and then use the cation as an electrostatic collector to preferentially select the wollastonite concentrate. 3. Reverse flotation process: According to the characteristics of wollastonite, for example, in the case of Jiangxi customers, sodium silicate is used as an inhibitor of wollastonite and quartz , and oxidized paraffin soap is used as a collector for calcite. The calcite is preferentially floated and separated, and the same principle is used. Quartz flotation is separated. The wollastonite ore dressing equipment to be configured in the above wollastonite beneficiation flotation process includes: PF jaw crusher , MQG lattice ball mill , vibrating screen, classifier, mixing tank, flotation machine, thickener, etc. Connected devices. 4, magnetic separation process: The magnetic separation process is generally used in a wollastonite ore dressing production line with a relatively low grade. The weak magnetic minerals in the wollastonite ore can be separated by a magnetic separator to improve the grade of the wollastonite ore. The main ore dressing equipment of the magnetic separation process production line includes: PF jaw crusher, MQG grid ball mill, vibrating screen, dry/wet magnetic separator. After the wollastonite is crushed and ground, the weak magnetic minerals are separated by magnetic separation machine, and then the wollastonite is separated from the associated ore such as calcite and quartz by a flotation process, and finally the wollastonite concentrate is obtained. The magnetic separation-flotation process is the most effective beneficiation process for the wollastonite beneficiation process. Through the two processes of flotation process and magnetic separation process, the grade and recovery rate of wollastonite beneficiation can be greatly improved, and wollastonite can be given. The mineral processing enterprise brings the greatest economic benefits.
Ship building Straight Pipe is used to connect pipes in the ship a variety of mechanical equipment, used to convey information about the working medium water, oil, gas and so on. Ship line has two categories: power lines and ship system piping. Power line is used for the main and auxiliary services of various piping for fuel, oil, cooling water, compressed air, exhaust gas, waste heat and other pipeline. Ship piping systems is to improve the anti-sinking, the ship's stability, in order to meet the crew, passengers need a normal life. Many systems ship systems, promising a full boat of marine and freshwater water supply system; to regulate use of ships' ballast water ballast system; to exclude the use of bilge water bilge discharge system; compressed air for the whole ship with compressed air systems; fire extinguishing systems and so on. These systems are used in equipment such as pumps and compressors mostly electric and automatic control.

Procedure
- cutting material
- Welding seam preparation
- Pre roll bending of plate tip
- Rolling
- Pre heating
- Welding the vertical seam inside
- outside gas gauging(gas explosion) and cleaning root, then welding outside
- rolling to correct ovality
- Respecting tollerance
- assembly and welding neck flanges, welding 100% full penetration, make sure the straightness, perpendicularity
- assemble and welding hoisting eyes and other plates on the pipe
- do blasing and painting.
Assembly
Installation fitting is the root of a separate straight pipes also the corresponding valve member is connected to the ship together, and with a fixed support, and devices connected to the system and finally to form a complete pipe system.

Introduction of wollastonite beneficiation process and configuration beneficiation equipment
The wollastonite beneficiation process program mainly includes a flotation process and a magnetic separation process. The flotation process includes a single flotation, a positive flotation, and a reverse flotation. The magnetic separation process includes a single magnetic separation and a magnetic separation-flotation combined process.
