Since May, the Harwusu Coal Preparation Plant has been actively conducting special inspections to enhance on-site safety management, eliminate potential hazards, and ensure the achievement of the "zero harm" goal. These efforts are part of a broader initiative to maintain a safe working environment for all employees.
Throughout the facility, safety protection measures have been implemented for various electromechanical equipment, including drums, couplings, high-speed shafts, and other rotating components found in driving stations, conveyor heads, tails, transfer points, corridors, and crushing areas. Inspections were carried out to ensure that all protective covers were properly in place, with any temporarily removed guards restored. Additionally, the high-altitude guardrails at the restroom platform near the coal bunker were reinforced, and the coal barrier at the tail of the M14 conveyor was replaced. These actions helped address existing risks and support safe operations across the plant.

Vitrified Grinding Wheels mean grinding wheels in ceramic bonded. Vitrified grinding wheels can be superabrasive grinding wheels like diamond grinding wheel or CBN Grinding Wheels. It also can be abrasive grinding wheels such as white aluminum oxide grinding wheel,pink grinding wheel,silicon carbide grinding.
Vitrified grinding wheel is only one type of bond, which is ceramic, it can be in any type of abrasive.
The main ingredient of vitrified bond are vitreous material with low melting point, such as borosilicate glass, lead glass, etc.It is widely used in various grinding methods such as outer circle, inner circle, flat surface, centerless, etc. It is the most commonly used bonding agent for abrasive tools.
Vitrified bond is characterized by high chemical stability, almost can work in a variety of cooling media, small elastic deformation, brittle, can be made into a variety of hardness levels of grinding tools to adapt to the processing of various hardness of the workpiece. Vitrified bond has good self-sharpening.
The grinding efficiency of single crystal diamond with vitrified bond grinding wheel is higher than metal bond grinding wheel. The wear ratio is very small and the processing cost is low. Therefore, the grinding efficiency of single crystal diamond with ceramic bond grinding wheel can be greatly improved.
