Gold mining equipment solution. Mining gold is a complexed progress. In order to get gold, we must crush the gold ore. So we need crushers. Jaw crusher is the most common crusher of gold mining equipments. South Africa is the country that is abound in gold ore. At there, HONXING has several crushing plant.
Impact crusher grinder for making 500 mesh mineral powders With excellent capacity and performance, it is widely used in machining of reduced for highway construction, hydraulic engineering and architecture, etc.
HONXING Dating from a solid foundation over 30 years ago, Hongxing Machinery Corporation has grown to be the largest manufacturers in mining crusher in China. HONXING is professional in impact crusher, Mobile impact crusher.Aiming to be always a faithful partner, HONXING has successfully strived to develop sustainable progress and harmonious partnership with our worldwide dealer network.
Safedem conducted several trials to determine the most efficient way of dealing with this concrete monster. First, excavator-mounted hydraulic breakers were tried out, but it quickly became clear that mechanical demolition on its own would not meet the challenge.

HONXING coal Impact Crusher is a new product that absorbs advanced technologies at home and abroad. Dealing with the material with the side length 500mm, not more than 350Mpa anti-pressure strength, it can be widely used in the first and secondary crushing. The company vertical impact crusher and Steel impact crusher is characterized by great reduction ratio, high reduction efficiency, convenient maintenance, etc. The final product is in the shape of a cube.
Safedem then decided to trial explosive blasting followed by mechanical demolition. A number of 30 mm (1.2 in) diameter holes were drilled in a 1 m (3.3 ft) centre grid formation over areas up to 100 m2 (1,076 ft2), drilled to a depth of 2.2 m (7.2 ft) into the top three concrete layers of the roof. Because of the very heavy reinforcement in the concrete, this proved difficult and expensive due to breakage of drill rods and the high wear factor of drill bits.

During trial blasting, seismic monitoring was carried out to determine air over pressure and vibration levels. Various locations across the site were selected for this monitoring and in particular at positions immediately adjacent to the nearby residential homes. From the results, Safedem agreed with the local authority that the maximum weight of charge for each future blast would not exceed 25 kg (55 lb).
