(1) Mineral processing and processing methods China's wollastonite mines generally have a high grade, and only a small number of picks can be obtained to obtain special, primary and secondary wollastonite nuggets. Float and magnetic separation methods are used to remove the associated quartz , calcite and iron minerals only when the wollastonite in the copper ore tailings is comprehensively recovered. However, due to the high cost, the application is not widespread. The processing of wollastonite is mainly to use high-quality nuggets, various kinds of grinding and ultra-fine grinding equipment to produce various specifications of wollastonite powder, and surface modification can be carried out when needed. (2) Dressing practice 1. Jilin Province Lishu Wollastonite Mining Company Jilin Province Lishu Wollastonite Mining Co., Ltd. cooperated with Wuhan University of Technology to develop LPM-630 fluidized bed airflow pulverizer for the production of wollastonite ultrafine powder (-10μm). A demonstration production line with an annual output of 200t wollastonite ultrafine powder was built. The production line consists of processes such as coarse crushing, medium crushing, fine crushing, ultrafine crushing, and product collection. The wollastonite nuggets are first crushed by a two-stage jaw crusher, passed through a hoist and a feed bin, and then passed into a Raymond mill for grinding. The grinding products (325 mesh) are collected by a cyclone classifier, and then passed through a hoist. The silo and the screw conveyor are fed into the LMP fluidized bed type jet mill, and the milled product is classified by the turbine classifier carried by the mill itself, and then sent to the product collector to obtain the final ultrafine wollastonite powder product. 2. Liyang Minghua Minerals Co., Ltd. Xiangyang Minghua Minerals Co., Ltd. is located in Daiyu Town, Fuyang City, Jiangsu Province. The company's fine powder materials company developed and produced a needle-like stripping machine, which is specially used for the production of wollastonite high aspect ratio needle powder. The process is: wollastonite primary product → stripping machine → classifier → packaging. The 60-200 mesh wollastonite powder processed by the stripping machine has an aspect ratio of 20:1. After the wind selection, the aspect ratio can reach 30:1. The production line has 8 stripping machines with a production capacity of 20,000 t/a wollastonite acicular powder. (3) Main deep processing product varieties and uses (1) Wollastonite fine powder (0 ~ 38μm) is mainly used for ceramic raw materials and glazes, paper, rubber, plastic fillers, paints and so on.
Hybrid Sedan is a type of car that combines an internal combustion engine with an electric motor and batteries, offering the advantages of both electric cars and traditional gas-powered sedans.
One advantage of Hybrid Sedans over electric cars is their extended driving range. As plug-in hybrid sedans, they can use both electricity and gasoline, providing flexibility for longer journeys and reducing range anxiety.
Additionally, Hybrid Sedans offer improved fuel efficiency compared to conventional gas-powered sedans, leading to reduced fuel consumption and lower carbon emissions.
As the automotive industry advances, the best midsize hybrid sedans showcase technological progress, providing a balance between performance and eco-friendliness.
Embracing Hybrid Sedans allows us to reduce our environmental impact while maintaining the convenience and practicality of traditional sedans.
While Hybrid Sedans offer benefits over both electric and gas-powered vehicles, the continuous development and adoption of electric and hybrid technologies will drive a cleaner and more sustainable future for transportation.

The processing process of wollastonite powder is generally: the ore that has been sorted to remove impurities is sent to the jaw crusher for coarse crushing and medium crushing, and then enters the Raymond mill or other dry grinding equipment for grinding, and the silica fume is obtained by cyclone classification. Stone ordinary powder. The ordinary powder is then sent to a fluidized bed or other type of jet mill for ultrafine pulverization to obtain ultrafine wollastonite powder or acicular wollastonite powder.
Crushing equipment for ore dressing: Commonly used jaw crusher for wollastonite crushing.
Processing mill equipment: including ordinary grinding equipment and ultra-fine grinding equipment. Ordinary grinding equipment is commonly used in Raymond mill and high-speed impact mill, mainly used to produce 200 mesh, 325 mesh wollastonite powder; ultrafine grinding equipment includes flat, circulating tube, fluidized bed and other airflow The pulverizer is mainly used to produce ultra-fine wollastonite powder and acicular powder of less than 10 μm.
(2) Wollastonite ultrafine powder (0~10μm) is mainly used for fillers such as paints, cables, rubber and plastics.
(3) Wollastonite acicular powder (length to diameter ratio of 10:1 and above) is mainly used for paint pigments, rubber plastic reinforcing agents, automobile clutches, brake fillers, and the like.
(4) Modified wollastonite powder is mainly used for functional fillers and reinforcing agents for cables, rubber plastics, resins, and the like.
