1 heavy hammer tension

The heavy hammer type tensioning device uses the gravity of the weight to generate the tension. The structure is simple, the work is reliable, the maintenance is small, and the application is very wide. The tensioning mode is characterized by constant under various working conditions. The tensioning force can automatically compensate for the change of the length of the conveying tape caused by temperature changes, mechanical wear and the like. The disadvantage is that the occupied space is large, the tension of the tension in the work fluctuates greatly, and the automatic adjustment cannot be performed immediately.

2 fixed tension

The tensioning roller of the fixed tensioning device is fixed in position during the operation of the conveyor, and the adjustment of the tensioning stroke has two modes: manual and electric. The advantage of this tensioning device is that the structure is simple and compact, and the work is reliable. The disadvantage is that the elastic deformation and plastic elongation generated by the belt during the operation of the conveyor cannot be timely compensated, thereby causing the tension to decrease, which may cause the conveyor belt to slip.

3 self-controlled tension

The self-controlled tensioning device automatically adjusts the tension of the conveyor belt according to the needs of different layouts of the belt conveyor, so that the conveyor can run more reliably and safely. For large-capacity, long-distance belt conveyors, the automatic tensioning device can ensure its effective and reliable operation, avoiding the phenomenon of slack, ribbon, deviation, and surge of the conveyor belt.

The self-controlled hydraulic tensioning device is a kind of self-controlled tensioning device, which has been fully applied on a large-capacity, long-distance, high-speed belt conveyor. Due to the different needs of the tension belt conveyor start and stop and normal operating conditions, the choice of controlled hydraulic tensioning device, can be adjusted automatically in accordance with the reasonable range for setting the tension of the conveyor belt, in line with modern advanced technology selected from coal Claim.

High-pressure Desorption Electrolysis

This series of equipment is oriented to the gold-loaded carbon in the gold cyanide carbon slurry process for gold desorption and electrolysis, and the gold adsorbed on the gold-loaded carbon is produced in the form of high-grade gold mud.

This series of equipment has 3 patented technologies and 5 proprietary technologies. Sodium cyanide is not used in the desorption liquid, which reduces the lean carbon grade below 100g/t. The key technology of this equipment is to ensure the balance of metal content, avoid the phenomenon of equipment "accumulation" and "floating gold", and ensure the stable and stable technical indicators of the equipment. The cost is low, and the content of technological advancement has been broadcast on the Spark Science and Technology column of CCTV in 2000. The technology passed the technical appraisal in 2003 and won the second prize of Science and Technology of the China Gold Association. The overall technical level is domestically leading. In 2006, it was designated as an energy-saving technology for gold production by the National Development and Reform Commission. In 2007, it was designated as an industry standard equipment by the National Development and Reform Commission. The equipment has obtained 3 Chinese patents, the patent numbers are: 01241537.5 01241538.5 200620029209.1
