Operation Instructions of Jaw Crusher 1.The preparation before starting: (1) Inspect each bearing to ensure whether it lubricates well, and whether there is enough lubricating grease on the toggle plate joints and bearing inners. (2) Check carefully whether all fasteners are totally fastened. (3) Check whether the drive belt is under good condition, and change the belt if any damages can be found. When there is grease contamination on the belt or bell wheel, it can be clean up with a clean dishcloth. (4) Check whether the protective device is under good condition, if there are any unusual events and safety hazards conditions, should correct them and report. (5) Check whether there are any ore or other impurities inside the crushing cavity. 2.The starting of the crusher (1) After inspecting the machine and transmission parts are under good condition, the machine may starts. (2) This machine can only start under empty load conditions. (3) After having started the machine, shut down the...
How much is a set of quarry plant, what equipment does it use? As we all know, gravel is a common material such as construction materials and highway construction materials. The plant mining gravel is called gravel yard, and the plant processing gravel is called gravel yard or stone factory. Granite is about 120~200MPa.Primary crushing usually adopts jaw crusher , which uses the extrusion and bending effect of two jaw plates on materials, crushes the crushing machinery of various hardness materials.The secondary crushing usually adopts impact crusher to produce the particle size of materials.SHUOSEN machine to recognize 300 tons per day of 300mm counterattack crusher feed particle size, discharging size and shape can be adjusted according to customer demand for multi-functional.In addition to the impact crusher, also can choose SHUOSEN machine spring crusher, cone crusher. Main factors for equipment selection can be summarized as follows: (1) the crusher is stable with continuous fee...
Common knowledge of mineral processing 1. What is productive rate? In the dressing process, the weight of a product and the percentage of raw ore weight, known as the productive rate. The production rate of each product is calculated as follows: Concentrate mineral rate 1=Q1/Q 100% Medium mineral rate 2=Q2/Q 100% Tail mineral rate 3=Q3/Q 100% Where Q -- raw ore weight, t; Q1 -- concentrate weight,t; T Q2 -- medium ore weight, t; Q3 -- tailings weight, t. What is the recovery rate? The concentration recovery is the percentage of the amount of metal (useful component) in the concentrate to the amount of metal (useful component) in the raw ore.This is an important mineral processing index, which reflects the degree of metal recovery, mineral processing technology and mineral processing quality.The recovery of ore dressing should be improved as much as possible on the premise of ensuring concentrate grade.The calculation method is as follows: 3. What is the Ore dressing ...
