Zimbabwe approves New Dawn’s indigenisation plan
Junior Canadian miner New Dawn Mining, which owns and operates several mines in three gold camps within in Zimbabwe,
on Friday announced that the Youth Development, Indigenisation and Economic Empowerment Minister had approved the company’s plan of indigenisation. Under the terms of the plan, four independent Zimbabwean indigenous investor groups and the National Indigenisation and Economic Empowerment Fund (NIEEF) would acquire equity in New Dawn, which were initially not expected to result in significant capital to the company.
The rotor is the main working parts of hammer crusher, hammer disc rotor comprises a main shaft, pin, hammer, etc. with pin holes distributed uniformly on the disk, with the pin axle suspension hammer, using the lock nuts on the pin shaft fixed at both ends in order to prevent axial disc and the hammer.
Hammer is the most important working parts of hammer crusher. The shape and material quality, hammer decides the hammer crusher production capacity and the size of the kinetic energy of the hammer head of hammer weight is proportional to the kinetic energy. The heavier hammer, the kinetic energy is greater, the crushing efficiency is higher.
According to the structure and properties hammer crusher is used in crushing coal, salt, chalk, gypsum, limestone, brick and tile. XSM hammer crusher also used for crushing waste fiber structure, strong flexibility and toughness of broken wood, paper or broken asbestos cement recycling to asbestos fibers, etc. And it is also suit for gold refinery machines equipment and plant.In addition, hammer crusher not only can be used for crushing production line, sand production line, but also can replace the cone crusher in the mineral processing production line.
Product AdvantageBearing adopts the integrated cast-steel structure, which ensures the ideal match with crusher frame.
Meanwhile, it significantly increases the radial intensity of bearing seat.Unique fixing device of blow bar brings larger reliability.Reformative adjusting device lower the time of machine quit and overhaul.Self-own open-top device can rapidly finish the replacement of wearing parts.Larger bearing specification and greater carrying capacity.Rotor analysis ensures stableness and reliability.Operational Principle
Material from the feed hopper into the impact of breaking the material, the impeller being rapidly accelerated acceleration of up to several hundred times the acceleration of gravity, and then from the impeller three uniform flow channel at a speed of 60-70 m/s projectile out, first of all with the part of the self-generated revenues falling by around the sub-feeder material impact crusher, and with the impact of the vortex cavity lining materials, material lining rebound oblique impact to the top of the whirl chamber, but also to change its direction of motion, deflected downward movement of material emitted from the impeller form a continuous materials curtain. Such a material eddy the crushing cavity by twice. As well as several times the probability of impact, friction and grinding crushing effect. The broken material is discharged from the lower part of the discharge opening. The entire crushing process, the materials be mutually self impact broken, not in direct contact with the metal components, but with the lining materials shock, friction and crushed, which reduces iron contamination, to extend the time of mechanical wear.
