With the scarcity of sand and gravel aggregates, machine-made sand aggregates have become the main force of construction sand. Granite is a common machine-made sand raw material. When processing granite materials, granite sand making machines are required. The granite sand making machine will inevitably have material blockage during use, which will affect the sand making efficiency and reduce the output. This article summarizes the causes of material clogging, and attaches solutions for your reference.
Reasons and treatment methods of blockage of granite sand making machine
- The material is inappropriate
If the material has a large water content, it may stick to the sand making machine and cause blockage of the granite sand making machine. An effective solution is to preheat at the entrance. If the material has a large particle size or high hardness, it will also cause equipment blockage, which needs to be crushed before being sent to the sand making machine. - The elasticity of the triangle belt is inappropriate
In the production process of the granite sand making machine, the power is transmitted to the pulley through the V-belt, and then the stone is crushed. When the V-belt is loose, it will cause slipping, and the material cannot be crushed by the normal crushing force in the crushing chamber, which will cause the material to be blocked. - Feeding speed is too fast
The feeding speed is not well matched with the processing speed, such as fast feeding, slow crushing, and slow discharging, which will cause material blockage. Therefore, when feeding the granite sand making machine, the uniformity and continuity of the feeding should be maintained. In addition, the change of the ammeter pointer should be paid attention to when feeding.
Generally speaking, if the feed speed is greater, the deflection angle of the ammeter pointer will be greater, and the motor will burn out due to long-term overload. In this case, immediately reduce or close the material gate, or increase the feeder to control the feeding speed to prevent the sand making machine from blocking the material. - Improper adjustment of the discharge port
In the production process of the granite sand making machine, if the discharge port is not adjusted properly, the discharge speed will be too slow, which will cause the subsequent crushed materials to accumulate in the outlet and the crushing cavity, causing discharging obstacles. - Coordination of production line equipment
If the conveying capacity of the belt conveyor exceeds the crushing capacity, when the conveying capacity of the conveyor does not match the crushing capacity of the crusher, the materials behind it will quickly enter the crusher without being crushed, resulting in untimely blockage. - The wear-resistant parts are severely worn
The materials entering the granite sand making machine cannot be completely broken and discharged in time, causing material blockage. Therefore, if the wearing parts of the granite sand making machine are severely worn, new wearing parts should be replaced in time. - The voltage is too low or unstable
When the voltage is too low or unstable, the actual processing capacity of the granite sand making machine will be lower than the theoretical value. At this time, if the feeding speed is not adjusted, it is easy to cause blockage. After the device is started, the voltage should be in a stable state.
When the granite sand making machine encounters material blocking problems, it is necessary to clean the materials in the crushing cavity in time to avoid affecting the production efficiency of machine-made sand and reduce the service life of the granite sand making machine equipment.
