The screen machine is equipped with double-layer screen plates according to customer needs and uses dual-axis vibration source excitation. It has a larger processing capacity and higher screening efficiency, and is energy-saving and environmentally friendly. The design concept of the gold vibrating screen breaks the design concept of the same vibration source, same amplitude, and same vibration frequency of the conventional vibrating screen, and can adopt a new structure that combines circular motion, elliptical motion, and linear motion. The collected ore needs to be transported from the mining area to the beneficiation plant for preliminary purification. This process usually uses equipment such as trucks and belt conveyors. The ore needs to be crushed and screened during transportation to break the ore into smaller particles and remove waste rock and impurities. The ore particles after preliminary purification are easier to enter the subsequent beneficiation process, thereby improvin...

The tin ore beneficiation process is roughly divided into four links: crushing, pre-selection, flotation, and re-selection. The connection between each stage is appropriate. Only when the equipment configuration is reasonable, the whole process of tin ore beneficiation technology will be smoother and more convenient to operate. 1. Crushing and screening The nature of the tin ore is relatively simple, and a simple one-step crushing with a jaw crusher can achieve good results. The ore is crushed to 20mm, and then screened into two particle sizes of 20-4mm and 4-0mm. After crushing, the tin ore particles are uniform in size, beautiful in shape, and without over-crushing, providing high-quality raw materials for the next link, reducing the load of the grinding equipment, and having a good promoting effect on improving the grade of tin concentrate. 2. Pre-selection The 20-4mm ore enters the heavy medium cyclone for pre-selection, and then after a rod mill, the jig is used for pre-selection...

This device can clean the waste brick-concrete particles mainly waste concrete and reduce the impurities on the aggregate surface, meet the basic requirements of recycled aggregate, and have high production efficiency. Product features (1) Research on the operation problems of the primary screening device, cleaning device and screening device First, the recycled concrete aggregate after crushing by the jaw crusher is poured into the primary screening device through a pipeline, and the impurities in the aggregate are screened out after the primary screening treatment. The fine aggregate with a particle size of less than 4.75mm enters the cleaning device; the impurities adsorbed on the aggregate surface are further removed by cleaning, and the recycled aggregate is soaked to reach a saturated state; the concrete aggregate after the above two procedures is poured into the screening device, and the aggregate is screened by adding screening nets of different particle sizes. The screened coa...

The fine sand recovery machine is a new type of fine sand recovery machine developed by the professional team of Longzhong fine sand recovery machine manufacturer based on previous production experience. The product is more practical and convenient, and the environmental protection function is enhanced. According to the feedback of users, a multifunctional, economical and practical new type of fine sand recovery machine is produced. The work flow of the fine sand recovery machine is similar to that of the previous fine sand recovery machine. The mud water flows into the cleaning tank, and the mud water is sent to the high-pressure separator through the wear-resistant pump to separate the sewage and sand. The sand passes through the nozzle to the dewatering screen, and is sent to the conveyor belt after dehydration. The sewage flows back to the return box, is divided into the cleaning tank, and the excess is discharged.

The spiral stone washer uses the buoyancy of water to separate dust and impurities from sand and gravel. After the agitation of the spiral blade, the purpose of filtering water to remove impurities is achieved. The spiral stone washing opportunity forms a sedimentation tank in the lower part of the inclined water tank. The spiral head is not inserted into the sedimentation tank. The spiral is rotated by the motor through the deceleration drive, and the cleaning water is fed from the bottom of the sedimentation tank to complete the functions of washing, dehydration and classification.
