Does anyone have the operating procedures and start-up plan for pyrite acid production?

http://bbs.hcbbs.com/thread-267883-1-1.html http://bbs.hcbbs.com/thread-93395-1-1.html You can refer to it

Large enterprises have them and can be used as a reference. Does anyone have one? I'd also like to see it.

I have it here. I'll help you find it. If I find it, I'll tell you about it above.

Yes, I will post it when I can

Operating Procedures for Pyrite Raw Materials of a Plant (For Reference) Operating Procedures for Raw Material Section 1. Job Tasks and Management Scope (1) Job Tasks: This position will crush and screen pyrite lumps, sulfur concentrates and zinc concentrates, and provide ore with sulfur content, water content and stable particle size to the roasting posts, the quantity of which meets the requirements of the roasting posts. (2) Management scope: From the ore storage yard inside and outside the raw material factory building to the outlet of the #14 belt conveyor, including all buildings, equipment and associated electrical equipment and appliances within this range. 2. Process flow and starting and stopping methods 1. Process: See the process flow chart with control points in the raw material section. 2. Driving method: In principle, start from the end of the process and work forward. (1) Check all equipment according to the above requirements and confirm that there are no problems before driving. (2) All equipment is required to be started without load when driving. (3) The driving sequence is: Pyrite: #10 Belt Conveyor (A110) → Disc Feeder (B102) → #9 Belt Conveyor (A109) → #5 Belt Conveyor (A105) → #4 Belt Conveyor (A104) → #3 Belt Conveyor (A103) → #2 Belt Conveyor (A102) → #1 Belt Conveyor (A101) - Vibration Screen (B105) → Sand blasting machine (B104) → #1 jaw crusher (B103) → #8 belt conveyor (A108) → #7 belt conveyor (A107) → Chain crusher (B107) → Vibrating screen (B106) → #6 belt conveyor (A106) → Electric grab bridge crane (B101). zinc concentrate: #14 Belt Conveyor (A114) → #13 Belt Conveyor (A113) → #12 Belt Conveyor (A112) → Chain Crusher (B109) → Vibrating Screen (B108) → #11 Belt Conveyor (A111) → Electric Grab Bridge Crane (B101). 3. Parking method: Make contact before stopping, stop feeding, and wait until there is no ore left in the equipment (or on the equipment) before stopping the machine. In principle, the process starts from the beginning to the end. The parking sequence is: Pyrite: Electric grab bridge crane (B101) → #6 belt conveyor (A106) → vibrating screen (B106) → chain crusher (B107) → #7 belt conveyor (A107) → #8 belt conveyor (A108) → #1 jaw crusher (B103) → sand blasting machine (B104) → vibrating screen (B105 ) → #1 belt conveyor (A101) → #2 belt conveyor (A102) → #3 belt conveyor (A103) → #4 belt conveyor (A104) → #5 belt conveyor (A105) → #9 belt conveyor (A109) → disc feeder (B102) → #10 belt conveyor (A110). zinc concentrate: Electric grab bridge crane (B101) → #11 belt conveyor (A111) → vibrating screen (B108) → chain crusher (B109) → #12 belt conveyor (A112) → #13 belt conveyor (A113) → #14 belt conveyor (A114).

3. Main equipment operation points (1) Before starting the self-centering vibrating screen, you should first check the lubrication of the bearings, check whether the screen is tensioned, whether there is any damage, whether the screen holes are blocked, and check whether the conveyor belt is tightened and whether all bolts are loose. It should be started without load, and then feed material to the screen when the screen shaft reaches the specified number of revolutions. The feed quantity should be uniform and the materials should be distributed across the entire width of the screen surface. The maximum temperature of the screen bearings shall not exceed 70°C. When the screen is running, you should pay attention to the sound it makes. If you find any abnormal sound, you should immediately find out the cause and try to eliminate it. Feeding should be stopped before the sieve is stopped, and the power can be cut off only after the sieve materials are discharged.

(2) Before starting the belt conveyor, check the running direction of each belt. If there are any unsafe factors or items that prevent the operation, they should be removed and cleaned in time. Only after confirming that there are no problems can the belt conveyor be driven. When the conveyor belt is running, it moves smoothly along the longitudinal center of the conveyor. If there are any abnormalities or the conveyor belt is found to be too tight or deviated, it should be adjusted and eliminated in time. When the transport machine is in use, it should be cleaned and inspected after each shift to extend the service life of the machine. Before stopping work, all transportation materials should be transported before parking. Materials are not allowed to be stored on the transportation belt. If it is found that the conveyor belt is unstable and swaying from side to side, or the running speed is uneven, sometimes fast and sometimes slow, the reason is that the former conveyor belt is too tight and the latter conveyor belt is too loose, the tensioning device should be adjusted appropriately. No repairs or movements are allowed while the transport aircraft is in operation. All protective covers must be closed before the transporter is started, otherwise it is prohibited to start. A signal must be given before starting work on the transport aircraft.

(3) Before starting the jaw crusher, check whether the lubrication of the bearings, the drive belt of the motor, protective devices, etc. are in good condition, and whether all fasteners are tight. Check whether the adjusting bolt is retracted and whether the adjusting seat is pressed tightly. Check whether the movable jaw plate is opposite to the tooth tip of the jaw plate, whether there is a gap on both sides of the movable jaw plate, and it is strictly prohibited to rub against the side guard plate. The crusher may only be started without load. If abnormal conditions are found during startup, the operation should be stopped immediately, and the operation can be restarted only after the abnormal conditions are identified and eliminated. Feeding can only be started after the crusher is operating normally. Materials should be added evenly into the crushing cavity to avoid side feeding or overcrowding. During normal operation, the temperature rise of the bearing should not exceed 30°C, and the maximum temperature should not exceed 70°C. When the above temperature is exceeded, the vehicle should be stopped immediately to identify the cause and eliminate it. Feeding should be stopped before stopping, and the motor can be turned off only after the material in the crushing cavity is completely discharged. If the machine stops due to material blockage during crushing, the motor should be turned off immediately and the material can be discharged before starting again. The crusher needs regular inspection and maintenance.

4. Position start and stop of grab bridge crane 1. Position start (2) Remove all debris in the car body and track. (2) Check the brake coil temperature of the motor. (3) Check whether there is heat in the motor transmission part and whether the fasteners are loose. (4) Whether the brake of the limit switch is flexible and correct, and whether the braking of each brake is reliable. (5) Whether the wire rope has broken strands, burrs, or deviations. (6) Whether the steel wire on the winch is twisted and whether the grab pulley is intact. (7) Check whether electrical equipment, such as switches, lines, and conductive rails, are intact. 2. Parking at the post (1) After completing the task, park the crane at the stairs. If maintenance is required, park it in a place convenient for work. (2) Before parking, release the remaining material in the grab bucket and release the grab bucket to the ground at a 180-degree corner. (3) Pull down the knife and remove the fuse.
