Most construction units prefer to stack their wastes directly on the construction field considering its convenience and little cost. In addition, the failure of arranging proper protective measures on the construction site causes the wastes heap to collapse, resulting in the road hindering and building crashing problems. Facing this serious situation, the Chinese mining machinery companies recommend the gold crusher south africa jaw crusher to process the construction wastes. However, there are still differences between Chinese manufacturers and the worlds advanced technology that needs us to pay more attention. There exist some deficiencies and flaws in the jaw crusher manufacturing process as follows: 1. The whole crushing procedure is too simple to realize multi-functional breaking. When the jaw crusher works, it will receive many types of materials with multi-phases that are to be crushed. The traditional crushing technology is unable to separate these materials completely from their phases, thus causing over crushing problems which decreases the useful elements and leads to crushing wastes and resource waste. 2. When the compressive strength reaches certain limit during the crushing process hammer mill for sale, the crushing equipment will consume too much energy without realizing ideal crushing effect. 3. Its too hard for the jaw crushers to complete the ultrafine grinding process in current technological condition because we need multi-stage processing to crush materials. Since the entire crusher is a giant in size with too much weight, lots of areas and strong supporting base are needed during the installation process. 4. Jaw crushers consume large amount of power and steel materials, so its hard to effectively realize energy saving.
