We design different kinds of roadheaders , water jet cutting , cutter bits and hydraulic nuts as hard rock cutting machine for mining. Roadheaders are indispensable equipment for infrastructure construction for road tunnels, railroad tunnels, dam headrace tunnels, coal-mine drifts, etc.
EBZ135 cantilever-type roadheader as hard rock cutting machine is low height in structure, uses imported pilot control hydraulic system with high reliability, flexible operation and adapts to minimum cross-section of 6 square meters, can work in conditions where hardness coefficient= f7.
EBZ160 cantilever-type roadheader as hard rock cutting machine with telescopic cutting arm, can achieve positioning cutting. Hydraulic system uses imported hydraulic components, with high reliability. Adapts to minimum cross-section of 7 square meters. Suitable for working in coal mine, water conservancy tunnel, engineering excavation, potash mine, sodium mine, bauxite and other geological conditions with hardness coefficient of f8. Equipped with a scraper conveyor, it can achieve rapid excavation and uninterrupted transportation.
EBZ230 cantilever-type roadheader as hard rock cutting machine uses imported hydraulic components with high reliability. Adapts to minimum section of 7.8 square meters. Suitable for work in coal mine, water conservancy tunnel, engineering excavation, potash mine, sodium mine, ore, bauxite and other geological conditions with hardness coefficient upto f8.
QSM-3.5-15-BJ waterjet cutting machine as hard rock cutting machine is used for directly cutting transport pipelines, oil tanks and other flammable and combustible articles, or cooperating with public security or fire control department for emergently coping with oil leakage accidents or traffic accidents of transport vehicles of flammable and combustible articles by undertaking emergent cutting operations.
QSM-4.5-15-BF waterjet cutting machine as hard rock cutting machine is applied to solve the issue that the ordinary waterjet cutting machine is unable to enter narrow sites of underground coal mines for cutting operations, in addition to the multi-storey platform of chemical enterprises and other environments restricted by water and electricity supply conditions, by realizing quick connection within a minute.
QSM-4.5-15-BG portable waterjet cutting machine as hard rock cutting machine, is used for cutting any 0-100mm–thick materials (except glass carbon, diamond and special hard alloy), and has obtained the certificate of Mining Products Safety Label and met the requirements for coal mine safety production. It is suitable for cutting operations on sites with water or electricity for underground coal mines to avoid risks of dismantling or maintaining high gas flammable and combustible equipment and eliminate the danger of flammable and combustible tanks confronted by chemical enterprises during the process of dismantlement and maintenance.
QSM-5-15-B-SH waterjet cutting machine as hard rock cutting machine is a new type of portable cutting equipment functioning by front-mix abradant water jet flow; it adopts cold cutting technologies.This waterjet cutting machine has passed spark test, static electricity test and temperature test, and met the anti-explosion requirements.Note: QSM-5-15-B-SH waterjet cutting machine is an integral part of the main machine system and provides high-pressure water jet flows for cutting operations; it needs to assist cutters (for example pipe cutter), cutting gun assembly and high/low-pressure hose to complete cutting operations.
Cutting bit as hard rock cutting machine is a kind of wearable part in roadway excavation machinery, roadheaders. It is the main tool for cutting rock and mineral. Common raw material from the majority of domestic and imported suppliers is : 42Cr, 35CrMnSi and other steel, hardness of up to 40-45HRC, impact toughness of not less than 49J / cm2. Now with the ONE BELT ONE ROAD construction of China along the way, the ROADHEADER machinery has been used more and more in the roadway works apart from the mines due to its better flexibility and lower working cost. Moreover, the cutting-bits at the same time also need to withstand high periodic compressive stress, shear stress and impact load, which requires the cutter body parts to have very good impact resistance and withstand wear and tear.
The Hydraulic Nut as hard rock cutting machine is a permanent fixture, replacing the conventional nut and retaining the high bolt load and extension in small space envelopes where there may not be sufficient space to use tensioners. The nut can be retrofitted to existing plant and is a simple and accurate solution to mechanical jointing problems.
