How to solve blockage during the operation of crushing equipment

There are many reasons why sand and stone processing equipment gets clogged while running. Common causes include material characteristics, improper operation and equipment issues.

If the materials contain too much moisture, they will stick to the machine easily. A practical fix is to heat the materials at the feed inlet to cut down moisture content before processing. Overly hard or oversized materials also frequently lead to clogging. For this case, make sure to crush or break down raw materials into proper sizes before feeding them into the machine.

Clogs also happen when materials are fed in too fast while the crushing speed cannot keep up. Running the machine under constant overload will burn out the motor. You need to feed materials steadily and continuously to prevent blockages.

This type of machine uses V-belts to drive pulleys for crushing. If the V-belt becomes loose, it will slip and fail to drive the pulleys normally. The materials will not be crushed properly and eventually cause a jam.

Slow discharge of finished sand will let crushed materials pile up inside the crushing chamber and outlet, resulting in clogging. Worn-out spare parts will leave materials incompletely crushed. Be sure to replace damaged wear parts in a timely manner.

Low or fluctuating voltage will reduce the machine’s actual working capacity. If you do not slow down the feed rate accordingly, clogs will occur easily. Keep the power voltage stable during operation.
