Based on the production demands of millions of customers, ZENITH has developed the industrial milling machines which cover fully the crude powder, fine powder and ultrafine powder. The tens of years of customer service experiences make ZENITH learn better the customer's investment ideas and considerations so as to provide specific solutions.
A grinding machine, often shortened to grinder, is a machine tool used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth. Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look or to attain a desired surface for a functional purpose.
Ball Mill is crucial equipment for grinding after materials are crushed. It is an efficient tool for grinding various materials into powder. Ball Mills widely applied in cement industry, chemical industry, new building materials, fire-resistant materials, fertilizer, porcelain and glass industry etc. It has two ways of grinding: dry process and wet process.
MTM Medium Speed Trapezium Grinding Mill is designed by our own engineers and technical workers to overcome the traditional grinding mill defect completely in application, capacity, fineness, energy consumption, service life, etc. This series of grinding mill has become a leading-world-level industrial mill. It adops numbers of national national patents and world-leading-powder processing technology, such as trapezium¡¯s working surface, flexible connection, roll urled pressure boost, etc.Now MTM Medium Speed Trapezium Grinding Mill is the ideal substitute of the traditional mill, such as Raymond mill, high pressure suspension grinding mill, ball mill, etc.
Coarse Powder Mill is a kind of new high-tech grinding mill to meet the requirements of sand processing customers. Based on over 30 years¡¯ research experience of our experts in the grinding mill industry and considering recommendations & requirements of domestic and foreign clients, it is the ideal equipment to replace the traditional grinding mill which only process powder materials. By being a component of closed production lines, coarse powder grinding mill can produce various size of products according to the requirements.
Most grinding wheels are made of silicon carbide or aluminum oxide, both of which are artificial (manufactured) abrasives. Silicon carbide is extremely hard but brittle. Aluminum oxide is slightly softer but is tougher than silicon carbide. It dulls more quickly, but it does not fracture easily therefore it is better suited for grinding materials of relatively high tensile strength.
Silicate bond releases the abrasive grains more readily than vitrified bond. Silicate bonded wheels are well suited for grinding where heat must be kept to a minimum, such as grinding edged cutting tools. It is not suited for heavy-duty grinding. Thin cutoff wheels are sometimes made with a shellac bond because it provides fast cool cutting.
The abrasive particles in a grinding wheel are held in place by the bonding agent. The percentage of bond in the wheel determines, to a great extent, the ¡°hardness¡± or ¡°grade¡± of the wheel. The greater the percentage and strength of the bond, the harder the grinding wheel will be. ¡°Hard¡± wheels retain the cutting grains longer, while ¡°soft¡± wheels release the grains quickly. The most common bonds used in grinding wheels are vitrified, silicate, shellac, resinoid, and rubber.
